Insert HTML into view

Question

Is it possible to create an HTML fragment in an AngularJS controller and have this HTML shown in the view?

This comes from a requirement to turn an inconsistent JSON blob into a nested list of id : value pairs. Therefore the HTML is created in the controller and I am now looking to display it.

I have created a model property, but cannot render this in the view without it just printing the HTML.

---

Update

It appears that the problem arises from angular rendering the created HTML as a string within quotes. Will attempt to find a way around this.

Example controller :

var SomeController = function () {

    this.customHtml = '<ul><li>render me please</li></ul>';
}

Example view :

<div ng:bind="customHtml"></div>

Gives :

<div>
    "<ul><li>render me please</li></ul>"
</div>

Answer 1

I have tried today, the only way I found was this

<div ng-bind-html-unsafe="expression"></div>

Answer 2

I found that using ng-sanitize did not allow me to add ng-click in the html.

To solve this I added a directive. Like this:

app.directive('htmldiv', function($compile, $parse) {
return {
  restrict: 'E',
  link: function(scope, element, attr) {
    scope.$watch(attr.content, function() {
      element.html($parse(attr.content)(scope));
      $compile(element.contents())(scope);
    }, true);
  }
}
});

And this is the HTML:

<htmldiv content="theContent"></htmldiv>

Good luck.

Answer 3

there is one more solution for this problem using creating new attribute or directives in angular.

product-specs.html

 <h4>Specs</h4>
        <ul class="list-unstyled">
          <li>
            <strong>Shine</strong>
            : {{product.shine}}</li>
          <li>
            <strong>Faces</strong>
            : {{product.faces}}</li>
          <li>
            <strong>Rarity</strong>
            : {{product.rarity}}</li>
          <li>
            <strong>Color</strong>
            : {{product.color}}</li>
        </ul>

app.js

 (function() {
var app = angular.module('gemStore', []);    
app.directive("     <div ng-show="tab.isSet(2)" product-specs>", function() {
return {
  restrict: 'E',
  templateUrl: "product-specs.html"
};
});

index.html

 <div>
 <product-specs>  </product-specs>//it will load product-specs.html file here.
 </div>

or

<div  product-specs>//it will add product-specs.html file 

or

<div ng-include="product-description.html"></div>

Another solution, very similar to blrbr's except using a scoped attribute is:

angular.module('app')
.directive('renderHtml', ['$compile', function ($compile) {
    return {
      restrict: 'E',
      scope: {
        html: '='
      },
      link: function postLink(scope, element, attrs) {

          function appendHtml() {
              if(scope.html) {
                  var newElement = angular.element(scope.html);
                  $compile(newElement)(scope);
                  element.append(newElement);
              }
          }

          scope.$watch(function() { return scope.html }, appendHtml);
      }
    };
  }]);

And then

<render-html html="htmlAsString"></render-html>

Note you may replace element.append() with element.replaceWith()

As of Angular 4, this is the way that now works:

<div [innerHTML]="htmlString">
</div>

Answer 6

Working example with pipe to display html in template with Angular 4.

1.Crated Pipe escape-html.pipe.ts

`

import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';
@Pipe({name : 'keepHtml', pure : false})
export class EscapeHtmlPipe implements PipeTransform{
 constructor(private sanitizer : DomSanitizer){
 }
 transform(content){
  return this.sanitizer.bypassSecurityTrustHtml(content);
 }
}

` 2. Register pipe to app.module.ts

 import {EscapeHtmlPipe} from './components/pipes/escape-html.pipe';
    declarations: [...,EscapeHtmlPipe]

3. Use in your template

       <div class="demoPipe"  [innerHtml]="getDivHtml(obj.header) | keepHtml">

4. getDivHtml() { //can return html as per requirement}

   Please add appropriate implementation for getDivHtml in associated component.ts file.
