Checkbox Id

Checkbox id is not displayed in user interface. Here, id mentions the id attribute of the root element of Checkbox control. When you assign a value for id property, then this older id is replaced by new id. This id value should be unique.

Set id for Checkbox control as follows.

HTML

<table width="600px">
    <tr>
        <td> Checkboxes </td>
        <td>
            <ej-checkbox type="checkbox" class="nodetext" id="check1" [(id)]="id"></ej-checkbox></td>
    </tr>
    </table>

HTML

import {Component} from '@angular/core';
@Component({
    selector: 'ej-app',
    templateUrl: './default.component.html',
})
export class DefaultComponent {
    id:string;
    constructor() {
        this.id="sync";
    }
}

Checkbox Id Prefix

Id prefix value is the one that is appended to id value. It is used to mention the prefix for the wrapper’s id attribute. When you assign a value for idPrefix property, the older prefix id is replaced by new prefix id.

Set prefix id for Checkbox control as follows.

HTML

<table width="600px">
    <tr>
        <td> Checkboxes </td>
        <td>
            <ej-checkbox type="checkbox" class="nodetext" id="check1" [(idPrefix)]="idPrefix"></ej-checkbox></td>
    </tr>
    </table>

HTML

import {Component} from '@angular/core';
@Component({
    selector: 'ej-app',
    templateUrl: './default.component.html',
})
export class DefaultComponent {
    idPrefix:string;
    constructor() {
        this.idPrefix="JS";
    }
}

Checkbox Name

The name attribute is used to identify from data after it is submitted to the server, or to reference from data using Angular on the client side. Checkbox also contains name attribute. This name should be a unique one. It is used to receive the Checkbox value. Without using name, you can’t get the particular checkbox values at the time of submitting form.

Checkbox Value

For Checkboxes, the contents of the value property do not appear in the user interface. The value property contains only a meaning when submitting a form. When a Checkbox is in checked state and when the form is submitted, the name of the Checkbox is sent along with the value of the value property (When the checkbox is not checked, no information is sent).

You can set name and value for Checkbox control as follows.

HTML

<table width="600px">
    <tr>
        <td> Checkboxes </td>
        <td>
            <ej-checkbox type="checkbox" class="nodetext" id="check1" [(name)]="name" [(value)]="value"></ej-checkbox></td>
    </tr>
    </table>

HTML

import {Component} from '@angular/core';
@Component({
    selector: 'ej-app',
    templateUrl: './default.component.html',
})
export class DefaultComponent {
    value: string;
    name: string;
    constructor() {
        this.value = "received";
        this.name = "Conformation";
    }
}
