[json] Angular 2: Get Values of Multiple Checked Checkboxes

  1. I have just simplified little bit for those whose are using list of value Object. XYZ.Comonent.html

    <div class="form-group">
            <label for="options">Options :</label>
            <div *ngFor="let option of xyzlist">
                <label>
                    <input type="checkbox"
                           name="options"
                           value="{{option.Id}}"
    
                           (change)="onClicked(option, $event)"/>
                    {{option.Id}}-- {{option.checked}}
                </label>
            </div>
            <button type="submit">Submit</button>
        </div> 
    

    ** XYZ.Component.ts**.

  2. create a list -- xyzlist.

  3. assign values, I am passing values from Java in this list.
  4. Values are Int-Id, boolean -checked (Can Pass in Component.ts).
  5. Now to get value in Componenet.ts.

    xyzlist;//Just created a list
    onClicked(option, event) {
        console.log("event  " + this.xyzlist.length);
        console.log("event  checked" + event.target.checked);
        console.log("event  checked" + event.target.value);
        for (var i = 0; i < this.xyzlist.length; i++) {
            console.log("test --- " + this.xyzlist[i].Id;
            if (this.xyzlist[i].Id == event.target.value) {
                this.xyzlist[i].checked = event.target.checked;
            }
            console.log("after update of checkbox" + this.xyzlist[i].checked);
    
        }
