this is part of my code:
<input style="width:100px;" #quantity name="vehicle{{i}}_quantity"
class="options-input" [(ngModel)]="detail.quantity" type="number" required [ngClass]="{ 'error-bottom-border': quantity.value.length==0}" placeholder="0" min="0" [disabled]="viewMode">
When I put a value to one of the inputs all others get the same value. I dont't want this. I tried to add:
[ngModelOptions]="{standalone: true}"
But still nothing. Every input has uniqe name.
I hope that is a simple case.
ALL CODE

did you use same ngModel for all the input? if yes that's the problem .Ngmodel is used to bind data to the input .

So I'm trying to make a form for my assignment, and I am using the pattern attribute in html so only certain characters are required to be typed on the text box. But for some reason, the form is saying using that I'm using an incorrect format even though I made my pattern attribute that way.
Here's an example of the code and a picture of the problem.
<form>
<label for="mnumber">Mobile Number:</label>
<input type="text" required id="mnumber" pattern="[0-9]"><br><br>
<input type="submit" value="submit">
</form>
You did write:
pattern="[0-9]"
You are asking for only one number. You just forget to add '+' to accept more than one number. I guess what you are searching for is this:
pattern="[0-9]+"
pattern="[0-9]"
allows for only a single number character to validate (and be submitted). If you want to allow more than one character, here's your options:
One or more numbers:
pattern="[0-9]+"
Zero or more numbers:
pattern="[0-9]*"
One to three numbers:
pattern="[0-9]{1,3}"
you just need to change type="text" to type="number"
is there a way to get an input value and retrieve if the value is highlighted?
I've a simple input:
<input type="text" id="myId" [(ngModel)]="myModel" (keypress)="myNumberInput($event)" min=0 max=99999/>
I'd should know throw event if the value in the input is highlighted. For example:
enter image description here
Is it possible to get this information in event?
Thanks
PS. I'm developing in Angular 2 so I need to do this without using jQuery.
This is working for me :
<input type="text" id="myId" [(ngModel)]="myModel" (select)="myNumberInput($event)" min=0 max=99999/>
I am trying to use multiple patterns for an input-field in HTML5.
<input type="text" pattern="\d*.{5,10}" name="plz">
My current input field does not work. Only the second pattern .{5,10} is relevant for the submit. The first attribute \d* hast no effects.
Try the below:
<input type="text" placeholder="" class="form-control" pattern="([0-9]{2})([0-9]{2})([0-9]{2})([0-9]{4})([0-9]{1})">
and just accept AESE640526HOCCNL05...
Hope this can help you.
Suppose this checkbox snippet:
<input type="checkbox" value="1">Is it worth?</input>
Is there any reason to statically define the value attribute of checkboxes in HTML? What does it mean?
I hope I understand your question right.
The value attribute defines a value which is sent by a POST request (i.e. You have an HTML form submitted to a server).
Now the server gets the name (if defined) and the value.
<form method="post" action="urlofserver">
<input type="checkbox" name="mycheckbox" value="1">Is it worth?</input>
</form>
The server would receive mycheckbox with the value of 1.
in PHP, this POST variable is stored in an array as $_POST['mycheckbox'] which contains 1.
I just wanted to make a comment on Adriano Silva's comment.
In order to get what he describes to work you have to add "[]" at the end of the name attribute, so if we take his example the correct syntax should be:
<input type = "checkbox" name="BrandID[]" value="1">Ford</input>
<input type = "checkbox" name="BrandID[]" value="2">GM</input>
<input type="checkbox" name="BrandId[]" value="3">Volkswagen</input>
Then you use something like: $test = $_POST['BrandID']; (Mind no need for [] after BrandID in the php code).
Which will give you an array of values, the values in the array are the checkboxes that are ticked's values.
Hope this helps! :)
One reason is to use the ease of working with values in the system.
<input type="checkbox" name="BrandId" value="1">Ford</input>
<input type="checkbox" name="BrandId" value="2">GM</input>
<input type="checkbox" name="BrandId" value="3">Volkswagen</input>
When the form is submitted, the data in the value attribute is used as the value of the form input if the checkbox is checked. The default value is "on".
$('form').on('change', update).trigger('change')
function update() {
var form = $(this)
form.find('output').text('→ ' + form.serialize())
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<input type="checkbox" name="foo">
<output></output>
</form>
<form>
<input type="checkbox" name="foo" checked>
<output></output>
</form>
<form>
<input type="checkbox" name="foo" value="1" checked>
<output></output>
</form>
<form>
<input type="checkbox" name="foo" value="bananas" checked>
<output></output>
</form>
For the sake of a quick glance answer, from MDN
when a form is submitted, only checkboxes which are currently checked are submitted to the server, and the reported value is the value of the value attribute
It can be confusing because seeing something like
<input type='checkbox' name='activated' value='1'> might lead one to believe that the 1 means true and it will be treated as though it is checked, which is false. The checked attribute itself also only determines if the checkbox should be checked by default on page load, not whether it is currently checked and thus going to be submitted.
I have a HTML page.
I want to have a input box, that has a default value, that people can select, but not write over. It if for a share link to the page.
How can I do this?
EDIT: Using readonly="readonly" works and satisfies the solution, but the mouse pointer becomes a stop sign. I have chosen to use pure text instead of putting the share link into an input box. A javascript/Jquery solution will be possible but I don't use scripts on my website.
give input box readonly property like
<input type="text" id="a" value="abc" readonly="readonly" />
you can use it as
<input type="text" id="a" value="abc" disabled="true"/>
you can also dynamically change this attribute using javascript as per your requirement.
add
readonly="readonly"..........
please notice :
readonly - is a markup class
we dont have to write x=x
so we can only write x
hence
<input type="text" id="a" value="abc" readonly />
also work
Method 1
input type="text" id="a" value="abc" disabled="true"
Method 2
input type="text" id="a" value="abc" readonly="readonly"
In first case, text field will be disabled and you will not be allowed to select the value, where as in the second method you can select it, but not able to edit it..
Disabled field are not accessible in successor pages.
You can also dynamically change this attribute using javascript as per your requirement.
