Ionic 2 LoadingController包含自定义内容

Question

I want to use custom components inside the content option of the LoadingController of my Ionic 2 project but when the loading comes up the browser console shows me the message:

WARNING: sanitizing HTML stripped some content (see http://g.co/ng/security#xss).

And the component is not showing, making test i realise that using any other TAG that was not standard HTML TAG throws this error, how i can use angular 2 security for bypass the error? what i whant is:

    this.loadingController.create({
        spinner: 'hide',
        content: `
        <div>
            <some-component></some-component>
            <h3>a message...</h3>
        </div>`
    })

Answer 1

Actually, you cannot do that according to the doc:

content ----> string ----> The HTML content for the loading indicator.

So you must pass the plain string HTML content like this:

content: `
      <div class="my-spinner">
        <div class="my-spinner-box"></div>
      </div>`,

Answer 2

This works for me:

//----------imports----------
import { DomSanitizer } from '@angular/platform-browser';

//----------variables----------
safeHtml: any;

//----------constructor----------
constructor(public loadingCtrl: LoadingController, private sanitizer: DomSanitizer)

//----------your function----------
let svg = '<svg xmlns="http://www.w3.org/2000/svg" viewBox...whatever..</svg>';
// you can also add text BEFORE sanitizing
let html = svg + '<div class="loadingText">' + this.translate.instant('common.Loading') + '</div>';

this.safeHtml = this.sanitizer.bypassSecurityTrustHtml(html);

var loading = this.loadingCtrl.create({
    spinner: 'hide',
    content: this.safeHtml
});
loading.present();
