angularjs - How to define place where dynamic components would be injected? -

-

my components injected dynamical. how define place without wrapping? 

import { component, viewcontainerref, componentresolver } '@angular/core';    constructor(     private apiservice: apiservice,     private viewcontainerref: viewcontainerref,     private componentresolver: componentresolver) {   }    create() {     this.componentresolver.resolvecomponent(piechart).then((factory) => {       this.viewcontainerref.createcomponent(factory);     });   }

and want inject them in div.

<div class="someclass">  <!--how inject them here?  --> </div>

there 2 ways:

  • injecting viewcontainerref in question, new components added below component

  • using target element in components template template variable <div #target></div> , @viewchild('target', {read: viewcontainerref}) viewcontainerref:viewcontainerref; viewcontainerref of <div>. added elements again added below <div>

createcomponent() allows pass index. default new components added @ end, if pass index inserted @ position.
(not tested) index 0 should able add new element before target element.
if add more 1 component same viewcontainerref can pass index insert new component before elements added earlier.
