Is it possible to use a CSS selector to target an input that has a specific value?
Example: How can I target the input below based on the value="United States"
<input type="text" value="United States" />
Dynamic Values (oh no! D;)
As npup explains in his answer, a simple css rule will only target the attribute value which means that this doesn't cover the actual value of the html node.
JAVASCRIPT TO THE RESCUE!
Ugly workaround: http://jsfiddle.net/QmvHL/
Original Answer
Yes it's very possible, using css attribute selectors you can reference input's by their value in this sort of fashion:
input[value="United States"] { color: #F90; }
• jsFiddle example
from the reference
[att] Match when the element sets the "att" attribute, whatever the
value of the attribute.
[att=val] Match when the element's "att"
attribute value is exactly "val".
[att~=val] Represents an element
with the att attribute whose value is a white space-separated list of
words, one of which is exactly "val". If "val" contains white space,
it will never represent anything (since the words are separated by
spaces). If "val" is the empty string, it will never represent
anything either.
[att|=val] Represents an element with the att
attribute, its value either being exactly "val" or beginning with
"val" immediately followed by "-" (U+002D). This is primarily intended
to allow language subcode matches (e.g., the hreflang attribute on the
a element in HTML) as described in BCP 47 ([BCP47]) or its successor.
For lang (or xml:lang) language subcode matching, please see the :lang
pseudo-class.
css attribute selectors reference
It is possible, if you're using a browser which supports the CSS :valid pseudo-class and the pattern validation attribute on inputs -- which includes most modern browsers except IE9.
For instance, to change the text of an input from black to green when the correct answer is entered:
input {
color: black;
}
input:valid {
color: green;
}
<p>Which country has fifty states?</p>
<input type="text" pattern="^United States$">
Yes, but note: since the attribute selector (of course) targets the element's attribute, not the DOM node's value property (elem.value), it will not update while the form field is being updated.
Otherwise (with some trickery) I think it could have been used to make a CSS-only substitute for the "placeholder" attribute/functionality. Maybe that's what the OP was after? :)
As mentioned before, you need more than a css selector because it doesn't access the stored value of the node, so javascript is definitely needed. Heres another possible solution:
<style>
input:not([value=""]){
border:2px solid red;
}
</style>
<input type="text" onkeyup="this.setAttribute('value', this.value);"/>
Sure, try:
input[value="United States"]{ color: red; }
jsFiddle example.
You can use Css3 attribute selector or attribute value selector.
/This will make all input whose value is defined to red/
input[value]{
color:red;
}
/This will make conditional selection depending on input value/
input[value="United States"]{
color:red;
}
There are other attribute selector like attribute contains value selector,
input[value="United S"]{
color: red;
}
This will still make any input with United state as red text.
Than we attribute value starts with selector
input[value^='united']{
color: red;
}
Any input text starts with 'united' will have font color red
And the last one is attribute value ends with selector
input[value$='States']{
color:red;
}
Any input value ends with 'States' will have font color red
Refreshing attribute on events is a better approach than scanning value every tenth of a second...
http://jsfiddle.net/yqdcsqzz/3/
inputElement.onchange = function()
{
this.setAttribute('value', this.value);
};
inputElement.onkeyup = function()
{
this.setAttribute('value', this.value);
};
In Chrome 72 (2019-02-09) I've discovered that the :in-range attribute is applied to empty date inputs, for some reason!
So this works for me: (I added the :not([max]):not([min]) selectors to avoid breaking date inputs that do have a range applied to them:
input[type=date]:not([max]):not([min]):in-range {
color: blue;
}
Screenshot:
Here's a runnable sample:
window.addEventListener( 'DOMContentLoaded', onLoad );
function onLoad() {
document.getElementById( 'date4' ).value = "2019-02-09";
document.getElementById( 'date5' ).value = null;
}
label {
display: block;
margin: 1em;
}
input[type=date]:not([max]):not([min]):in-range {
color: blue;
}
<label>
<input type="date" id="date1" />
Without HTML value=""
</label>
<label>
<input type="date" id="date2" value="2019-02-09" />
With HTML value=""
</label>
<label>
<input type="date" id="date3" />
Without HTML value="" but modified by user
</label>
<label>
<input type="date" id="date4" />
Without HTML value="" but set by script
</label>
<label>
<input type="date" id="date5" value="2019-02-09" />
With HTML value="" but cleared by script
</label>
Following the currently top voted answer, I've found using a dataset / data attribute works well.
//Javascript
const input1 = document.querySelector("#input1");
input1.value = "0.00";
input1.dataset.value = input1.value;
//dataset.value will set "data-value" on the input1 HTML element
//and will be used by CSS targetting the dataset attribute
document.querySelectorAll("input").forEach((input) => {
input.addEventListener("input", function() {
this.dataset.value = this.value;
console.log(this);
})
})
/*CSS*/
input[data-value="0.00"] {
color: red;
}
<!--HTML-->
<div>
<p>Input1 is programmatically set by JavaScript:</p>
<label for="input1">Input 1:</label>
<input id="input1" value="undefined" data-value="undefined">
</div>
<br>
<div>
<p>Try typing 0.00 inside input2:</p>
<label for="input2">Input 2:</label>
<input id="input2" value="undefined" data-value="undefined">
</div>
I am doing a phonegap app. When I am trying type="date" input field as shown below, it shows date picker in iPhone as I expected but it doesn't show the placeholder I have given. I found the same issue here in SO, but no solution anywhere.
<input placeholder="Date" class="textbox-n" type="date" id="date">
It may not be appropriate... but it helped me.
What I did is start with a text input field, then change the type to a date input when the input is in focus.
<input
placeholder="Date"
class="textbox-n"
type="text"
onfocus="(this.type='date')"
id="date" />
If you use mvp's method but add the onblur event to change it back to a text field so the placeholder text appears again when the input field looses focus. It just makes the hack a little bit nicer.
<input placeholder="Date" class="textbox-n" type="text" onfocus="(this.type='date')" onblur="(this.type='text')" id="date" />
I ended up using the following.
Regarding Firefox comment(s): Generally, Firefox will not show any text placeholder for inputs type date.
But as this is a Cordova/PhoneGap question this should be of no concern (Unless you want to develop against FirefoxOS).
input[type="date"]:not(.has-value):before{
color: lightgray;
content: attr(placeholder);
}
<input type="date" placeholder="MY PLACEHOLDER" onchange="this.className=(this.value!=''?'has-value':'')">
As of today (2016), I have successfully used those 2 snippets (plus they work great with Bootstrap4).
Input data on the left, placeholder on the left
input[type=date] {
text-align: right;
}
input[type="date"]:before {
color: lightgrey;
content: attr(placeholder) !important;
margin-right: 0.5em;
}
Placeholder disappear when clicking
input[type="date"]:before {
color: lightgrey;
content: attr(placeholder) !important;
margin-right: 0.5em;
}
input[type="date"]:focus:before {
content: '' !important;
}
I used this in my css:
input[type="date"]:before{
color:lightgray;
content:attr(placeholder);
}
input[type="date"].full:before {
color:black;
content:""!important;
}
and put somenthing like this into javascript:
$("#myel").on("input",function(){
if($(this).val().length>0){
$(this).addClass("full");
}
else{
$(this).removeClass("full");
}
});
it works for me for mobile devices (Ios8 and android). But I used jquery inputmask for desktop with input text type. This solution it's a nice way if your code run on ie8.
Based on deadproxor and Alessio answers, I would try only using CSS:
input[type="date"]::before{
color: #999;
content: attr(placeholder) ": ";
}
input[type="date"]:focus::before {
content: "" !important;
}
And if you need to make the placeholder invisible after writing something in the input, we could try using the :valid and :invalid selectors, if your input is a required one.
EDIT
Here the code if you are using required in your input:
input[type="date"]::before {
color: #999999;
content: attr(placeholder);
}
input[type="date"] {
color: #ffffff;
}
input[type="date"]:focus,
input[type="date"]:valid {
color: #666666;
}
input[type="date"]:focus::before,
input[type="date"]:valid::before {
content: "" !important;
}
<input type="date" placeholder="Date" required>
I took jbarlow idea, but I added an if in the onblur function so the fields only change its type if the value is empty
<input placeholder="Date" class="textbox-n" type="text" onfocus="(this.type='date')" onblur="(this.value == '' ? this.type='text' : this.type='date')" id="date">
According to the HTML standard:
The following content attributes must not be specified and do not apply to the element: accept, alt, checked, dirname, formaction, formenctype, formmethod, formnovalidate, formtarget, height, inputmode, maxlength, minlength, multiple, pattern, placeholder, size, src, and width.
It works for me:
input[type='date']:after {
content: attr(placeholder)
}
I used this whit jQuery:
http://jsfiddle.net/daviderussoabram/65w1qhLz/
$('input[type="date"], input[type="datetime"], input[type="datetime-local"], input[type="month"], input[type="time"], input[type="week"]').each(function() {
var el = this, type = $(el).attr('type');
if ($(el).val() == '') $(el).attr('type', 'text');
$(el).focus(function() {
$(el).attr('type', type);
el.click();
});
$(el).blur(function() {
if ($(el).val() == '') $(el).attr('type', 'text');
});
});
Found a better way to solve your problem.
I think this will help you. when focused out, the box will change type into text so it will show your placeholder. when focused in, its type changes into date so the calendar view will be shown.
<input placeholder="Date" class="textbox-n" type="text" onfocusin="(this.type='date')" onfocusout="(this.type='text')" id="date">
<input placeholder="01-01-2021" class="textbox-n" type="text" onfocus="(this.type='date')" onblur="(this.type='text')" id="date" />
Adressing the problem in the current correct answer "clicking the field shows the onscreen keyboard instead of the datepicker":
The problem is caused by the Browser behaving according to the type of input when clicking (=text). Therefore it is necessary to stop from focussing on the input element (blur) and then restart focus programmatically on the input element which was defined as type=date by JS in the first step. Keyboard displays in phonenumber-mode.
<input placeholder="Date" type="text" onfocus="this.type='date';
this.setAttribute('onfocus','');this.blur();this.focus();">
To summarize the date inputs problem:
You have to display them (i.e. avoid display:none) otherwise the input UI will not be triggered ;
a placeholder is contradictory with them (as per the spec, and because they have to display a specific UI) ;
converting them to another input type for the unfocused time do allows placeholders, but focus then triggers the wrong input UI (keyboard), at least for a small time, because focus events cannot be cancelled.
inserting (before) or adding (after) content doesn't prevent the date input value to be displayed.
The solution I found to meet those requirements is to use the usual trick to style native form elements : ensure the element is displayed but not visible, and display its expected style through its associated label. Typically, the label will display as the input (including a placeholder), but over it.
So, an HTML like:
<div class="date-input>
<input id="myInput" type="date">
<label for="myInput">
<span class="place-holder">Enter a date</span>
</label>
</div>
Could be styled as:
.date-input {
display: inline-block;
position: relative;
}
/* Fields overriding */
input[type=date] + label {
position: absolute; /* Same origin as the input, to display over it */
background: white; /* Opaque background to hide the input behind */
left: 0; /* Start at same x coordinate */
}
/* Common input styling */
input[type=date], label {
/* Must share same size to display properly (focus, etc.) */
width: 15em;
height: 1em;
font-size: 1em;
}
Any event (click, focus) on such an associated label will be reflected on the field itself, and so trigger the date input UI.
Should you want to test such a solution live, you can run this Angular version from your tablet or mobile.
try my solution. I use 'required' attribute to get know whether input is filled and if not I show the text from attribute 'placeholder'
//HTML
<input required placeholder="Date" class="textbox-n" type="date" id="date">
//CSS
input[type="date"]:not(:valid):before {
content: attr(placeholder);
// style it like it real placeholder
}
Took me a while figuring this one out, leave it as type="text", and add onfocus="(this.type='date')", just as shown above.
I even like the onBlur idea mentioned above
<input placeholder="Date" class="textbox-n" type="text" onfocus="(this.type='date')" onblur="(this.type='text')" id="date">
Hope this helps anyone who didn't quite gather whats going on above
SO what i have decided to do finally is here and its working fine on all mobile browsers including iPhones and Androids.
$(document).ready(function(){
$('input[type="date"]').each(function(e) {
var $el = $(this),
$this_placeholder = $(this).closest('label').find('.custom-placeholder');
$el.on('change',function(){
if($el.val()){
$this_placeholder.text('');
}else {
$this_placeholder.text($el.attr('placeholder'));
}
});
});
});
label {
position: relative;
}
.custom-placeholder {
#font > .proxima-nova-light(26px,40px);
position: absolute;
top: 0;
left: 0;
z-index: 10;
color: #999;
}
<label>
<input type="date" placeholder="Date">
<span class="custom-placeholder">Date</span>
</label>
Date
Im working with ionicframework and solution provided by #Mumthezir is almost perfect. In case if somebody would have same problem as me(after change, input is still focused and when scrolling, value simply dissapears) So I added onchange to make input.blur()
<input placeholder="Date" class="textbox-n" type="text" onfocus=" (this.type='date')" onchange="this.blur();" id="date">
You can
set it as type text
convert to date on focus
make click on it
...let user check date
on change store the value
set input to type text
set text type input value to the stored value
like this...
$("#dateplaceholder").change(function(evt) {
var date = new Date($("#dateplaceholder").val());
$("#dateplaceholder").attr("type", "text");
$("#dateplaceholder").val(date.getDate() + "/" + (date.getMonth() + 1) + "/" + date.getFullYear());
});
$("#dateplaceholder").focus(function(evt) {
$("#dateplaceholder").attr("type", "date");
setTimeout('$("#dateplaceholder").click();', 500);
});
$("#dateplaceholder").attr("type", "text");
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<input type="date" id="dateplaceholder" placeholder="Set the date" />
Found a better way to handle user basic comprehension with mouseover and opening datepicker on click :
<input type="text" onfocus="(this.type='date')" onmouseover="(this.type = 'date')" onblur="(this.value ? this.type = 'date' : this.type = 'text')" id="date_start" placeholder="Date">
Also hide webkit arrow and make it 100% wide to cover the click :
input[type="date"] {
position: relative;
}
input[type="date"]::-webkit-calendar-picker-indicator {
position: absolute;
height: 100%;
width: 100%;
opacity: 0;
left: 0;
right: 0;
top:0;
bottom: 0;
}
Expanding on #mvp's solution with unobtrusive javascript in mind, here's the approach:
HTML:
<input type="text" placeholder="Date" class="js-text-date-toggle">
Javascript:
$('.js-text-date-toggle').on('focus', function() {
$(this).attr('type', 'date');
}).on('blur', function() {
$(this).attr('type', 'text');
});
I think all you have to do is change the model to say the date field is nullable and then put [Required] on it if it is required. If you do this the placeholder text does appear.
Hey so I ran into the same issue last night and figured out a combination of all of your answer and some sparkling magic are doing a good job:
The HTML:
<input type="date" name="flb5" placeholder="Datum" class="datePickerPlaceHolder"/>
The CSS:
#media(max-width: 1024px) {
input.datePickerPlaceHolder:before {
color: #A5A5A5; //here you have to match the placeholder color of other inputs
content: attr(placeholder) !important;
}
}
The jQuery:
$(document).ready(function() {
$('input[type="date"]').change(function(){
if($(this).val().length < 1) {
$(this).addClass('datePickerPlaceHolder');
} else {
$(this).removeClass('datePickerPlaceHolder');
}
});
});
Explanation:
So, what is happening here, first of all in the HTML, this is pretty straight forward just doing a basic HMTL5-date-input and set a placeholder.
Next stop: CSS, we are setting a :before-pseudo-element to fake our placeholder, it just takes the placeholder's attribute from the input itself. I made this only available down from a viewport width of 1024px - why im going to tell later.
And now the jQuery, after refactoring a couple of times I came up with this bit of code which will check on every change if there is a value set or not, if its not it will (re-)add the class, vice-versa.
KNOW ISSUES:
there is a problem in chrome with its default date-picker, thats what the media-query is for. It will add the placeholder infront of the default 'dd.mm.yyyy'-thing. You could also set the placeholder of the date-input to 'date: ' and adjust the color incase of no value inside the input...for me this resulted in some other smaller issues so i went with just not showing it on 'bigger' screens
hope that helps!
cheerio!
From Angular point of view I managed to put a placeholder in input type date element.
First of all I defined the following css:
.placeholder {
color: $text-grey;
}
input[type='date']::before {
content: attr(placeholder);
}
input::-webkit-input-placeholder {
color: $text-grey;
}
The reason why this is neccessary is that if css3 content has different color that the normal placeholder, so I had to use a common one.
<input #birthDate
class="birthDate placeholder"
type="date"
formControlName="birthDate"
placeholder="{{getBirthDatePlaceholder() | translate}}"
[class.error]="!onboardingForm.controls.birthDate.valid && onboardingForm.controls.birthDate.dirty"
autocomplete="off"
>
Then in the template used a viewchild birthDate attribute, to be able to access this input from the component. And defined an angular expression on the placeholder attribute, which will decide if we show the placeholder or not. This is the major drawback of the solution, is that you have to manage the visibility of the placeholder.
#ViewChild('birthDate') birthDate;
getBirthDatePlaceholder() {
if (!this.birthDate) {
return;
} else {
return this.birthDate.nativeElement.value === '' ?
'ONBOARDING_FORM_COMPONENT.HINT_BIRTH_DATE' :
'';
}
}
<input placeholder="Date" type="text" onMouseOver="(this.type='date')" onMouseOut="(this.type='text')" id="date" class="form-control">
Revised code of mumthezir
If you're only concerned with mobile:
input[type="date"]:invalid:before{
color: rgb(117, 117, 117);
content: attr(placeholder);
}
I'm surprised there's only one answer with an approach similar to the one I used.
I got the inspiration from #Dtipson's comment on #Mumthezir VP's answer.
I use two inputs for this, one is a fake input with type="text" on which I set the placeholder, the other one is the real field with type="date".
On the mouseenter event on their container, I hide the fake input and show the real one, and I do the opposite on the mouseleave event. Obviously, I leave the real input visibile if it has a value set on it.
I wrote the code to use pure Javascript but if you use jQuery (I do) it's very easy to "convert" it.
// "isMobile" function taken from this reply:
// https://stackoverflow.com/a/20293441/3514976
function isMobile() {
try { document.createEvent("TouchEvent"); return true; }
catch(e) { return false; }
}
var deviceIsMobile = isMobile();
function mouseEnterListener(event) {
var realDate = this.querySelector('.real-date');
// if it has a value it's already visible.
if(!realDate.value) {
this.querySelector('.fake-date').style.display = 'none';
realDate.style.display = 'block';
}
}
function mouseLeaveListener(event) {
var realDate = this.querySelector('.real-date');
// hide it if it doesn't have focus (except
// on mobile devices) and has no value.
if((deviceIsMobile || document.activeElement !== realDate) && !realDate.value) {
realDate.style.display = 'none';
this.querySelector('.fake-date').style.display = 'block';
}
}
function fakeFieldActionListener(event) {
event.preventDefault();
this.parentElement.dispatchEvent(new Event('mouseenter'));
var realDate = this.parentElement.querySelector('.real-date');
// to open the datepicker on mobile devices
// I need to focus and then click on the field.
realDate.focus();
realDate.click();
}
var containers = document.getElementsByClassName('date-container');
for(var i = 0; i < containers.length; ++i) {
var container = containers[i];
container.addEventListener('mouseenter', mouseEnterListener);
container.addEventListener('mouseleave', mouseLeaveListener);
var fakeDate = container.querySelector('.fake-date');
// for mobile devices, clicking (tapping)
// on the fake input must show the real one.
fakeDate.addEventListener('click', fakeFieldActionListener);
// let's also listen to the "focus" event
// in case it's selected using a keyboard.
fakeDate.addEventListener('focus', fakeFieldActionListener);
var realDate = container.querySelector('.real-date');
// trigger the "mouseleave" event on the
// container when the value changes.
realDate.addEventListener('change', function() {
container.dispatchEvent(new Event('mouseleave'));
});
// also trigger the "mouseleave" event on
// the container when the input loses focus.
realDate.addEventListener('blur', function() {
container.dispatchEvent(new Event('mouseleave'));
});
}
.real-date {
display: none;
}
/* a simple example of css to make
them look like it's the same element */
.real-date,
.fake-date {
width: 200px;
height: 20px;
padding: 0px;
}
<div class="date-container">
<input type="text" class="fake-date" placeholder="Insert date">
<input type="date" class="real-date">
</div>
I tested this also on an Android phone and it works, when the user taps on the field the datepicker is shown. The only thing is, if the real input had no value and the user closes the datepicker without choosing a date, the input will remain visible until they tap outside of it. There's no event to listen to to know when the datepicker closes so I don't know how to solve that.
I don't have an iOS device to test it on.
This might help in some situation.
<input type="text" id="date" onclick="this.type='date'" onblur="this.type='text'" placeholder="Date" class="textbox-n" name="myDate" />
HTML:
<div>
<input class="ui-btn ui-btn-icon-right ui-corner-all ui-icon-calendar ui-shadow" id="inputDate" type="date"/>
<h3 id="placeholder-inputDate">Date Text</h3>
</div>
JavaScript:
$('#inputDate').ready(function () {
$('#placeholder-inputDate').attr('style'
, 'top: ' + ($('#placeholder-inputDate').parent().position().top + 10)
+ 'px; left: ' + ($('#placeholder-inputDate').parent().position().left + 0) + 'px; position: absolute;');
$('#inputDate').attr('style'
, 'width: ' + ($('#placeholder-inputDate').width() + 32) + 'px;');
});
Here is another possible hack not using js and still using css content. Note that as :after is not supported on some browser for inputs, we need to select the input in another way, same for content attr('')
input[type=date]:invalid+span:after {
content:"Birthday";
position:absolute;
left:0;
top:0;
}
input[type=date]:focus:invalid+span:after {
display:none;
}
input:not(:focus):invalid {
color:transparent;
}
label.wrapper {
position:relative;
}
<label class="wrapper">
<input
type="date"
required="required"
/>
<span></span>
</label>
I'm currently using readonly="readonly" to disable fields. I'm now trying to style the attribute using CSS. I've tried using
input[readonly] {
/* styling info here */
}
but it is not working for some reason. I've also tried
input[readonly='readonly'] {
/* styling info here */
}
that doesn't work either.
How can I style the readonly attribute with CSS?
input[readonly]
{
background-color:blue;
}
https://curtistimson.co.uk/post/css/style-readonly-attribute-css/
Note that textarea[readonly="readonly"] works if you set readonly="readonly" in HTML but it does NOT work if you set the readOnly-attribute to true or "readonly" via JavaScript.
For the CSS selector to work if you set readOnly with JavaScript you have to use the selector textarea[readonly].
Same behavior in Firefox 14 and Chrome 20.
To be on the safe side, i use both selectors.
textarea[readonly="readonly"], textarea[readonly] {
...
}
Loads of answers here, but haven't seen the one I use:
input[type="text"]:read-only { color: blue; }
Note the dash in the pseudo selector. If the input is readonly="false" it'll catch that too since this selector catches the presence of readonly regardless of the value. Technically false is invalid according to specs, but the internet is not a perfect world. If you need to cover that case, you can do this:
input[type="text"]:read-only:not([read-only="false"]) { color: blue; }
textarea works the same way:
textarea:read-only:not([read-only="false"]) { color: blue; }
Keep in mind that html now supports not only type="text", but a slew of other textual types such a number, tel, email, date, time, url, etc. Each would need to be added to the selector.
To be safe you may want to use both...
input[readonly], input[readonly="readonly"] {
/*styling info here*/
}
The readonly attribute is a "boolean attribute", which can be either blank or "readonly" (the only valid values). http://www.whatwg.org/specs/web-apps/current-work/#boolean-attribute
If you are using something like jQuery's .prop('readonly', true) function, you'll end up needing [readonly], whereas if you are using .attr("readonly", "readonly") then you'll need [readonly="readonly"].
Correction:
You only need to use input[readonly]. Including input[readonly="readonly"] is redundant. See https://stackoverflow.com/a/19645203/1766230
There are a few ways to do this.
The first is the most widely used. It works on all major browsers.
input[readonly] {
background-color: #dddddd;
}
While the one above will select all inputs with readonly attached, this one below will select only what you desire. Make sure to replace demo with whatever input type you want.
input[type="demo"]:read-only {
background-color: #dddddd;
}
This is an alternate to the first, but it's not used a whole lot:
input:read-only {
background-color: #dddddd;
}
The :read-only selector is supported in Chrome, Opera, and Safari. Firefox uses :-moz-read-only. IE doesn't support the :read-only selector.
You can also use input[readonly="readonly"], but this is pretty much the same as input[readonly], from my experience.
input[readonly], input:read-only {
/* styling info here */
}
Shoud cover all the cases for a readonly input field...
capitalize the first letter of Only
input[readOnly] {
background: red !important;
}
<input type="text" name="country" value="China" readonly="readonly" />
If you select the input by the id and then add the input[readonly="readonly"] tag in the css, something like:
#inputID input[readonly="readonly"] {
background-color: #000000;
}
That will not work. You have to select a parent class or id an then the input. Something like:
.parentClass, #parentID input[readonly="readonly"] {
background-color: #000000;
}
My 2 cents while waiting for new tickets at work :D
Use the following to work in all browsers:
var readOnlyAttr = $('.textBoxClass').attr('readonly');
if (typeof readOnlyAttr !== 'undefined' && readOnlyAttr !== false) {
$('.textBoxClass').addClass('locked');
}
