I have a select element in the form with different options. On property of the 'select' is onchange="testRecurrence(this.form)" and the js function it's just:
function testRecurrence(form) {
if(form.repeat.value != "N") {
form.endR.style.display = 'inline';
}
return true;
}
Being 'repeat' the select and 'endR' the item I want to display in case the option value is not "N". The issue here is that this is not working... been trying to find a solution but not able. Any help?
update
Not working, the element stay always hidden. The element endR by default has display:none.
update2
js function changed to:
function testRecurrence(form) {
if(form.repeat.options[form.repeat.selectedIndex].value != 'N')
document.getElementById('endR').style.display = 'inline';
}
html:
<select name="repeat" onchange="testRecurrence(this.form)">
...
<div id="endR" style="display: none">
...
</div>
It works now. Thank you.
I think getting the value of a select element doesn't work on all browsers, but this should do:
form.repeat.options[form.repeat.selectedIndex].value

So i have an input with a dropdown underneath. So when i click into an input the dropdown opens. But i can't select anything from the dropdown cause it is not focussed. So when i click on a value it doesnt get selected and the dropdown closes again because it looses focus. So i am now wondering how i can include the div into the focus of the input.
HTML input:
<input type="text" class="form-control myInput" [(ngModel)]="textToSort"
(keyup)="onKeyDownAction($event)" (blur)="onBlurEventAction()" id="{{id}}"
(focus)="focusFunction()" (focusout)="unFocusFunction()"/>
HTML div (dropdown):
<div class="data-container" *ngIf="showDropDown" style="position: absolute;" >
<p
*ngFor="let data of dataList; let i = index"
class="data-list"
(click)="updateTextBox(i,data[columnName]); focusOnInput();"
[ngClass]="{highlight:checkHighlight(i)}"
> {{data[columnName]}}</p>
</div>
Component:
focusFunction(){
this.showDropDown = true;
}
unFocusFunction() {
this.showDropDown = false;
}
blur event happens on your input because of mousedownon list item
So in order to prevent this you need to add
(mousedown)="$event.preventDefault()"
handler for your list items.
I created simple demo:
https://stackblitz.com/edit/angular-x3cdr1
Have you in your CSS, tried setting the z-index to 1 for the dropdown class when it is expanded?
Please share a plunkr or a stackblitz link to look at the scenario.
The simplest approach would be as follows:
focusFunction(){
this.showDropDown = true;
}
unFocusFunction() {
setTimeout(() => { this.showDropDown = false; }, 500);
}
I think checking this stackblitz would help also:

I'm using a selectbox on a Bootstrap platform to list multiple country flags that can be selected. On select the URL should be changed to the page of the country.
However, since I am not using <option> values, I don't know how to accomplish this. When I do work with <option> the flags won't display as shown below. Does anyone know how to add on select for this function?
<div class="bfh-selectbox bfh-countries pull-left" data-flags="true" data-country="NL" data-flags="true" data-blank="false" data-available="NL,BE">
</div>
Got it.
$(document).ready(function(){
$('.bfh-selectbox').on('change.bfhselectbox', function () {
if($(this).val()=="something"){
window.location.href="http://www.somelink.com";
}
else if($(this).val()=="somethingelse"){
window.location.href="http://www.someotherlink.com";
}
else {
}
});
});
I have a div with some text and I want when the cursor is hover this div to select the text. If I let this div as it is, when trying to select all (CTRL+A) then I select all page content, meaning all body text.
To get rid of this, I need to use contenteditable attribute for this div.
But I don't want to let people to change the text / copy / cut and so on
I try to use readonly for this div, but doesn't working.
Any advice please ?
PS1: This div has also other tags inside (html content), but I don't think that this is a problem.
PS2: An example is here: jsfiddle.net/msakamoto_sf/wfae8hzv/ - but with a problem. You can cut the text :(
Use event.metaKey in the keydown event to check if ctrl (or cmd on mac) keys are being pressed. You also have to disable the cut and paste events.
<div
contenteditable="true"
oncut="return false"
onpaste="return false"
onkeydown="if(event.metaKey) return true; return false;">
content goes here
</div>
You can prevent the user from cutting by handling the "cut" event and calling its preventDefault() method. This will prevent cut with any user input (including the browser's context menu or edit menu), not just via a particular key combination.
This example uses jQuery because your jsFiddle uses it:
$("#editablediv").on("cut", function(e) {
e.preventDefault();
});
set contenteditable to false and it should work !! that simple.
use contenteditable attribute for div to make it editable or not
and use readonly attr for form input elements.
<element contenteditable="true|false">
<input readonly="readonly" />
Here's an example in React, but it would work with basic HTML and JavaScript as well because I'm just leveraging the default events.
// import CSS
import './DefaultSettings.css';
// import packages
import React, { Component } from 'react';
// import components
const noop = (e) => {
e.preventDefault();
return false;
};
class DefaultSettings extends Component {
render() {
return (
<div className="DefaultSettings"
contentEditable={true}
onCut={noop}
onCopy={noop}
onPaste={noop}
onKeyDown={noop}>
</div>
);
}
}
export default DefaultSettings;
To prevent ctrl + x (Cut) from div you need to use following JQuery :
if (event.ctrlKey && event.keyCode === 88)
{
return false;
}
It will prevent to cut text from div.
Check Fiddle Here.
on user id condition set contentEditable="false"
for JavaScript,
document.getElementById(divid).contentEditable = "false";
this will work
I need to disable a div in AngularJS depend on a condition. Yes I can do it by using css change (giving low contrast and less color appearance) in appearance but I have ng-click property in it. So I need to prevent that calling also. How can I do it?
Here is my code:
<div ng-repeat="item in list.items" ng-click="goToFunction()" ng-disabled="true">
Yes ng-disabled does not work for div. It will for each html element which support the disable property (eg : input).
https://docs.angularjs.org/api/ng/directive/ngDisabled
I created a simple fiddle to demonstrate how to achieve it with a simple div http://jsfiddle.net/5Qc5k/1/
function MyCtrl($scope, $templateCache) {
$scope.isDisabled = false;
$scope.alertMe = function(){
if($scope.isDisabled === true){
return;
}
// disable the function
$scope.isDisabled = true;
alert("foo");
}
}
You can do that in controller ie:
<div ng-repeat="item in list.items" ng-click="goToFunction(item)" ng-disabled="true">
and after that in controller:
function goToFunction(item){
if(item.condition == disable){
return false
}
else {
// do something
}
}
To prevent the ng-click functionality based on disable you can do in following:-
<div ng-repeat="item in list.items" ng-disabled="item.condition" ng-click="goToFunction(item)">
item.value
</div>
$scope.goToFunction = function(item){
if(item.condition == false){
// Dont do anything
}else{
//do something
}
In this scenario when div is disabled, click functionality wont do anything, otherwise it will do.
I don't know if this is possible but I would like to have an input field where I would have a value that is not editable by the user.
However, I don't want the input field to be "readonly" because I still want the user to be able to add text after the value.
If you have any idea on how to do this, let me know please that would help me a lot.
EDIT: I use html forms.
You can position the text on top of the input field to make it look as if it is inside it. Something like this:
<input type="text" name="year" style="width:3.5em;padding-left:1.5em;font:inherit"><span style="margin-left:-3em;margin-right:10em;">19</span>
This way your input field will start with "19" which can not be edited, and the user can add information behind this.
Basically what you do is set the input field to a fixed width, so that you know how much negative margin-left to give the span with your text in it in order for it to be positioned exactly at the start of the input field.
You might need to fiddle with the margin-left of the span depending on the rest of your css.
Then also adding pedding-left to the input field, to make sure the user starts typing after your text and not under it.
font:inherit should make sure both your text and the text typed by the user are in the same font.
And if you want to put anything to the right of this input field, do add margin-right to the span with your text, as otherwise other content might start running over your input field as well.
seems a little weird to me ..why not just use a text output and afterwards the input field?
like sometimes used for the birthdate (although, maybe not anymore..)
birthyear: 19[input field]
edit:
with some javascript stuff you could realise something like that you asked for, though
an input field with text and catching keystrokes within that field while only allowing some after what you want to be always there - but, well, you would need to use js ..and if its just for that, Id rather say its not necessary
edit:
if you want to use a trick just for the viewer you could use a background-image/border-style that surrounds a text and the input field, thus making it look like text and input are the same input-box.
Sounds like you want placeholder text. In HTML5 you can set the placeholder attribute on any input element. This will work in modern browsers.
<input type="email" placeholder="jappleseed#appletree.com" name="reg_email" />
Now, for older browsers this won't work. You'll need a JavaScript alternative to provide the same UI value.
This can work for all browsers:
<input type="text" value="Search" onfocus="if (this.value == 'Search') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Search';}">
but it's not recommended because there is a better way (really, it's a combination of the first two approaches): Use HTML5 markup for new browsers; jQuery and modernizr for old browsers. This way you can have only one set of code that will support all user cases.
Taken directly from webdesignerwall.com:
<script src="jquery.js"></script>
<script src="modernizr.js"></script>
<script>
$(document).ready(function(){
if(!Modernizr.input.placeholder){
$('[placeholder]').focus(function() {
var input = $(this);
if (input.val() == input.attr('placeholder')) {
input.val('');
input.removeClass('placeholder');
}
}).blur(function() {
var input = $(this);
if (input.val() == '' || input.val() == input.attr('placeholder')) {
input.addClass('placeholder');
input.val(input.attr('placeholder'));
}
}).blur();
$('[placeholder]').parents('form').submit(function() {
$(this).find('[placeholder]').each(function() {
var input = $(this);
if (input.val() == input.attr('placeholder')) {
input.val('');
}
})
});
}
</script>
[You'll need both jquery.js and modernizr.js installed in the same folder as your webpage.]
Note: I have a feeling that a little more research might reveal that modernizr isn't needed for this at all, though I could be wrong about that particular point.
Perhaps, then, you want a select menu?
<select name="mySelectMenu">
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
</select>
Sorry if this isn't what you want either. I'm grasping at straws because what you are asking for is very vague. Maybe you should give an example of what one of these 'editable but not editable' inputs would be used for.
Also, you could use a select and a text input.
The main problem is to determine the position of the cursor. This can be done e.g. using the following function:
function getCaret(el) {
var pos = -1;
if (el.selectionStart) {
pos = el.selectionStart;
}
else if (document.selection) {
el.focus();
var r = document.selection.createRange();
if (r != null) {
var re = el.createTextRange();
var rc = re.duplicate();
re.moveToBookmark(r.getBookmark());
rc.setEndPoint('EndToStart', re);
pos = rc.text.length;
}
}
return pos;
}
Now you can install an event handler for the key press and check whether the pressed key was inside the immutable part of the value of the textarea. If it was there the event handler returns false, otherwise true. This behavior can be wrapped into a simple object:
function Input(id, immutableText) {
this.el = document.getElementById(id);
this.el.value = immutableText;
this.immutableText = immutableText;
this.el.onkeypress = keyPress(this);
}
function keyPress(el) {
return function() {
var self = el;
return getCaret(self.el) >= self.immutableText.length;
}
}
Input.prototype.getUserText = function() {
return this.el.value.substring(this.immutableText.length);
};
var input = new Input("ta", "Enter your name: ");
var userText = input.getUserText();
You can check it on jsFiddle (use Firefox or Chrome).
I came up with this:
```
if (e.target.value == '' || e.target.value.length <= 3) {
e.target.value = '+91-';
}
```
