You can add ng-change
<label><input type="checkbox" ng-model="cartorder.tax" ng-checked="{{item}}" ng-change="onChange(cartorder);">{{item.taxtype}}</label>
js
$scope.onChange = function(cartorder){
};

My html code,
<div>
<div>
<input type="checkbox" id="Checkbox0" name="cCheckbox0" class="custom-control-input" (change)="checkSelected(checkBox[0].label)">
<label class="label" for="Checkbox0" >first</label>
</div>
<div>
<input type="checkbox" id="Checkbox1" name="cCheckbox1" class="custom-control-input" (change)="checkSelected(checkBox[1].label)">
<label class="label" for="Checkbox1" >first</label>
</div>
<div>
<input type="checkbox" id="Checkbox2" name="cCheckbox2" class="custom-control-input" (change)="checkSelected(checkBox[2].label)">
<label class="label" for="Checkbox2" >first</label>
</div>
</div>
<div>
<div>
<input type="checkbox" id="Checkbox3" name="cCheckbox3" class="custom-control-input" (change)="checkSelected(checkBox[3].label)">

Likewise I have two more separate divs in the same html file which contains checkboxes. What I need to do is onclick of first checkbox in first div ,I need to disabled every other checkboxes from the first div,second div & third.
As I'm totally new to angular I have no idea how to disable here. I have tried using ng-disabled but it seems not working. Can someone help me with this?
For Angular 2+, you can enable / disable the checkbox by setting the disabled attribute on the input type=checkbox
Use: [attr.disabled]="isDisabled ? true : null"
Note here that [attr.disabled]="isDisabled alone will not work. You will need to explicitly set disabled attribute to null for removing disabled attribute from the disabled checkbox.
<input type="checkbox" [attr.disabled]="isDisabled ? true : null" />
ng-disabled is AngularJS syntax. You can use [disabled] input for disable checkboxes.
<input [disabled]="isDisabled" = type="checkbox" id="Checkbox0" name="cCheckbox0" class="custom-control-input" (change)="checkSelected(checkBox[0].label)">
in .ts isDisabled : boolean;
Optional thing
You can use Angular Material for your developments. because it has many advantages. And also it has well defined API.
<mat-checkbox> provides the same functionality as a native <input type="checkbox"> enhanced with Material Design styling and animations.
Angular Material
You can use the [disable] attribute your input[type="checkbox"] tag.
For eg: -
<input [disabled]="isDisabled" type="checkbox" id="Checkbox3" name="cCheckbox3" class="custom-control-input" (change)="checkSelected(checkBox[3].label)">
isDisabled variable will hold the boolean value in your .ts
For larger, more complex forms I highly recommend using a reactive form. With a reactive form, you can use [disabled]="condition" where the condition is something like whateverCheckbox.value.
UPDATE:
I updated my answer to use whateverCheckbox.value as opposed to whateverCheckbox.checked. This approach only works with reactive forms. I highly recommend using reactive forms for larger, more complex forms where you may need more detailed, personalized control over the elements of the form. Reactive forms are built around observable streams, where form inputs and values are provided as streams of input values, also while giving you synchronous access to the data.
Here is the documentation: https://angular.io/guide/reactive-forms
Once you have the form set up as a reactive form, a form control instantiated and bound to the checkbox input form element, you should be able to access the value of the checkbox as indicated above.
UPDATE 2: You don't necessarily need to use a form either to take advantage of a reactive form control.
In your component.ts file import FormControl from #angular/forms as below:
import { FormControl } from '#angular/forms';
Then declare the form control in the component class, as such:
checkbox1 = new FormControl('');
Then in your template, simply bind that FormControl to the input element as such:
<input type="checkbox" [formControl]="checkbox1">
and then you should be able to access that value anywhere using:
checkbox1.value
If you are using reactive forms you can also disable the checkbox from the component like this
import { FormBuilder, FormGroup } from '#angular/forms';
constructor(private _fb: FormBuilder) { }
myForm: FormGroup;
ngOnInit(): void {
this.myForm = this._fb.group({
myCheckBoxInput: [{value: 1, disabled: true}],
});
}
in reactive form, you can disable the checkbox like so
this.formGroup.get('Checkbox1').disable({ onlySelf: true });
<input id="isChecked" name="isChecked"
type="checkbox"></input><input name="_isChecked"
type="hidden" value="on"></input> <label for="isChecked">Checked</label>
I have this checkbox on the top of my *.html.
I want to use the value of "isChecked" input in a "form" like seting 1/0 (true/false) to a hidden input:
<form id="someForm" class="form xml-display form-inline"
th:action="#{/doSomething}" method="post">
.....
<input type="hidden" name="isChecked"
th:value="GET VALUE FROM THE GLOBAL CHECKBOX" />
.....
</form>
So can I do this without any JS?
Should I add an object in my java controller to the Model so I can set the value from the "isChecked" checkbox to it and then use the object in th:value="${objectFromJavaController}" for the hidden input ? I tried setting a th:object="${objectFromJavaController}" for the checkbox and then passing it to the hidden input but it didn't work (th:value = ${"objectFromJavaController"}) ?
So can someone help me ? Thanks in advance!
Surely somethin like this is simple enough?
<input id="newsletter" name="newsletter" type="checkbox" checked="yes" value="yes"/>
This brings back the same result. anything else would be no. (with PHP code telling them apart)
I have a form on my webpage and its being submitted to a NodeJS backend.
I'm having trouble with the checkboxes. When the are submitted to server, and I read them via req.body.foods, I get something like ['on', 'on', 'on'].
But I want to get the actual values, that is, something like ['dairy', 'fish'] etc.
How can I do that?
<div class="col-sm-6">
<div class="checkbox">
<label><input name="food" type="checkbox" value="dairy">Dairy</label>
</div>
<div class="checkbox">
<label><input name="food" type="checkbox" value="meat">Meat</label>
</div>
<div class="checkbox">
<label><input name="food" type="checkbox" value="fish">Fish</label>
</div>
</div>
You can do the following in the node.js file:
console.log(req.body.food); //This will print the array of values.
If you have only one checkbox selected in the page, (eg: Dairy) it will print "dairy". If more than one checkbox, then you get "{ 'dairy', 'meat' }" in the output. Make sure the checkboxes are within the form.
Another method:
Include a hidden input element in your form:
<input name="SelectedValues" type="hidden" value="">
Also include a call to a javascript file in the onchange event of every checkbox, or in the onclick event of the submit button in the form.
onclick='buildlist("YourCheckBoxName","SelectedValues");'
Use a javascript function to loop through your checkbox and build a comma separated list of selected values:
function buildlist(listName,labelName){
var controls = document.getElementsByName(listName);
var label = document.getElementsByName(labelName);
label.value = '';
for(var i=0;i<controls.length;i++){
label.value += controls[i].value.toString()+',';
}
}
Now inside the node.js file, use the following code to access the list of values:
req.body.SelectedValues
Looks like you are using bootstrap to generate your form checkboxes. Try using the "form-check" and "form-check-input" classes instead.
<div class="form-check">
<input class="form-check-input" type="checkbox" name="food" value="dairy" id="flexCheckDefault">
<label class="form-check-label" for="flexCheckDefault">Dairy</label>
</div>
I have check box at UI side on which i want to bind data coming from web service in form of jason
Html code:
<label class="checkbox-inline nopaddingleft" for="radio1">
<input name="radio1" type="checkbox" id="radio1"
class="checkbox-inline margin-right-five"
value="name" checked={{insuredProfile.isScrubbed}} />Scrub
</label>
The value i want to bind is:{{insuredProfile.isScrubbed}} it will be true or false
Thanks in advance
In your view use ngChecked.
In your controller you'll need to have something like:
$scope.insuredProfile = { isScrubbed: true };
You have to use ng-model for the checkbox input.
ng-model="insuredProfile.isScrubbed"
I have a label tag that I am trying to link to an input type checkbox tag. I have multiple labels and multiple checkbox inputs, and they all have the same id and the same name, but different values. Can someone instruct me as how to construct a label that links to a value rather than an id? So this:
<label for="8994"></label>
Would link to:
<input id="member_ids_" name="member_ids[]" type="checkbox" value="8994">
Or is this not possible?
The label's for attribute must match the ID of the <input> element it refers to. In your case it would be something like:
<label for="member_id_8994"></label>
<input id="member_id_8994" name="member_ids[]" type="checkbox" value="8994">
The 'for' for the form element must match with the ID of the same form element.
<label for="id_1"></label>
<input id="id_1" name="member_ids[1]" type="checkbox" value="8994">
<label for="id_2"></label>
<input id="id_2" name="member_ids[2]" type="checkbox" value="8994">
<label for="id_3"></label>
<input id="id_3" name="member_ids[3]" type="checkbox" value="8994">
<label for="id_3"></label>
<input id="id_3" name="member_ids[4]" type="checkbox" value="8994">
Your DOM elements must have different IDs.
Even if each ID is just set to whatever that value is... ...or whatever.
They can not have the same ID.
Once you've got that out of the way, setting for on a label becomes really simple.
I doubt if that is possible. Label's for are tied to the id attribute of inputs. One way to do achieve your objective maybe through javascript, knockout's declarative bindings for instance.
check it our here: http://knockoutjs.com/documentation/introduction.html
Something along this line:
<label data-bind="click: myInput"></label>
<input type="checkbox" id="hello">
<script type="text/javascript">
var myInput= {
//implement the function to bind the label to the input#hello here
}
};
</script>

A jQuery solution that probably doesn't work.
$(function() {
ModifyLabels({target: $('input')});
$('input').change(ModifyLabels);
});
function ModifyLabels(eventObject) {
var inputs = $(eventObject.target);
input.each(function(i, input) {
$('label').each(function(i, label) {
if ($(label).attr('for') == $(input).val()) {
$(input).attr('id', $(input).val());
}
});
});
}
