angular - Angular2 How to get reference of HTML elements generated dynamically -
i have inputs generated dynamically:
<div *ngfor="let cell of column; let = index;"> <!-- material design input--> <md-input id="my-input-{{i}}"> </md-input> </div>
please notice id=my-input-{{i}}
reference dom element based on dynamic id. input can 3, 6 or more inputs need access id dynamically , hold it.
use elementref
class @angular/core
parent element , create htmlelement
dynamic elements class name.
component:
declare var $: any; //intentional use of jquery-not recommended though @component({ selector: 'my-app', template: ` <input type='button' (click)='adddiv()' value='add new div' /> <input type='button' (click)='selectdiv()' value='select' /> ` }) export class app { constructor(private elref: elementref) { } adddiv() { /*intentional use of jquery appending new div give class dynamic elements*/ $('my-app').append("<div class='foo'>hello i'm dynamic!</div>"); } selectdiv() { //create new htmlelement nativeelement var helement: htmlelement = this.elref.nativeelement; //now can elements class name var alldivs = helement.getelementsbyclassname('foo'); //do selected elements console.log(alldivs); } }
edit: used jquery
quick demo purpose here. otherwise, you should not use jquery
angular
.
