Angular - Interpolate string with html

问题

So i've got a "template string" that looks like this:

var templateString = "Hello my name is {{name}}";

The name that I want to interpolate is a in variable. So I proceeded this way:

var miniScope = {
 name: "Chuck"
};

var sentence = $interpolate(templateString)(miniScope);
/* sentence: "Hello my name is Chuck" */

This works. Now I'd like to bold the name. I've obviously tried:

var miniScope = {
 name: "<strong>Chuck</strong>"
};

But the html code gets escaped. Any idea how I can achieve this?

PS: For those of you who wonder why I don't just put the string in the template, it's because my template string is coming from the server.

回答1:

This Plunkr outputs "Hello my name is Chuck" as expected. The JavaScript is unchanged from the question.

var app = angular.module("app", ["ngSanitize"]);
app.controller("TestCtrl", TestCtrl);
function TestCtrl($scope, $interpolate) {
  var templateString = "Hello my name is {{name}}";

  var miniScope = {
    name: "<strong>Chuck</strong>"
  };

  $scope.sentence = $interpolate(templateString)(miniScope);
}

And in your HTML, make use you use ng-bind-html to keep the HTML from being encoded.

  <body ng-controller="TestCtrl">
    <div ng-bind-html="sentence"></div>
  </body>

回答2:

use this directive to compile stuff from the string.

.directive('compile', ['$compile', function ($compile) {
return function(scope, element, attrs) {
    scope.$watch(
        function(scope) {
            return scope.$eval(attrs.compile);
        },
        function(value) {
            element.html(value);
            $compile(element.contents())(scope);
        }
    );
};
}])


$scope.name = "Vladimir";
$scope.str = "Hello my name is <strong>{{name}}</strong>";


<div compile="str"></div>

and use $sce to compile trusted html if You need Angular $sce doc

but all of this stuff not angular way actualy, You have to use some different partials and include it with ng-include directive.
