Question

我正在努力从JSON字符串中显示HTML代码。您可以在地址中看到HTML标记。有什么方法可以正确显示它吗？

我的模板是：

<div ng-app ng-controller="jsonp_example">
    <ul ng-repeat="item in data">
        <li>{{item.ID}}</li>
        <li>{{item.post_title}}</li>
        <li ng-bind-html-unsafe="getContent(obj)">{{item.custom_fields.sponsor_address}}</li>
        <li>
            <img src="{{item.custom_fields.sponsor_logo}}" width="100">
            <ul>
                <li>
                   <hr>
                </li>
            </ul>
        </li>
    </ul>
</div>

脚本：

function jsonp_example($scope, $http) {
    $scope.getContent = function (obj) {
        return obj.custom_fields.sponsor_address
    };

    var url = "https://eventident.com/api/getposts/?auth_key=s2mEus39R296M5F6n343A3dh9c62f7cm&custom_post=sponsors&callback=JSON_CALLBACK";

    $http.jsonp(url).success(function (data) {
        $scope.data = data.result;
    });
}

Answer 1

Did you include angular-sanitize.js as a dependency ? (as a script and as angular module dependency)

Also, you don't need to {{}} with ng-bind-html, just

<li ng-bind-html="item.custom_fields.sponsor_address"></li>

will do.

Answer 2

You need to include the ngSanitize service and directly use ng-bind-html.

Here is an updated jsfiddle from yours: http://jsfiddle.net/e01xj547/9/

Answer 3

You might need to explicitly trust the html string by using the $sce service. E.g var trustedHtml=$sce.trustAsHtml('<em>My html string</em>');

In your case to following usage would be appropirate:

function jsonp_example($scope, $http, $sce) {

    $scope.getContent = function (obj) {
        return $sce.trustAsHtml(obj.custom_fields.sponsor_address);
    };

    var url = "https://eventident.com/api/getposts/?auth_key=s2mEus39R296M5F6n343A3dh9c62f7cm&custom_post=sponsors&callback=JSON_CALLBACK";

    $http.jsonp(url).success(function (data) {
        $scope.data = data.result;
    });
}
