You can use the ng-bind-html directive to display it as an html content with all the html entities decoded. Just make sure to include the ngSanitize dependency in your application.

您可以使用ng-bind-html指令将其显示为html内容，并解码所有html实体。只需确保在应用程序中包含ngSanitize依赖项。

angular.module('app', ['ngSanitize'])

  .controller('Ctrl', function($scope) {
    $scope.html = '&quot;12.10 On-Going Submission of &quot;&quot;Made Up&quot;&quot; Samples.&quot;';
  });

If you don't want to use ngSanitize, you can do it this way:

如果您不想使用ngSanitize，可以这样做：

in your controller:

在你的控制器中：

$scope.html = '&quot;12.10 On-Going Submission of &quot;&quot;Made Up&quot;&quot; Samples.&quot;'
$scope.renderHTML = function(html_code)
        {
            var decoded = angular.element('<textarea />').html(html_code).text();
            return $sce.trustAsHtml(decoded);
        };

And in the template:

在模板中：

<div ng-bind-html="renderHTML(html)"></div>

Just make sure you inject $sce in your controller

只需确保在控制器中注入$ sce

I have similar issue, but don't need to use result value on UI. This issue was resolved by code from angular ngSanitize module:

我有类似的问题，但不需要在UI上使用结果值。此问题已通过角度ngSanitize模块中的代码解决：

var hiddenPre=document.createElement("pre");
/**
* decodes all entities into regular string
* @param value
* @returns {string} A string with decoded entities.
*/
function decodeEntities(value) {
  if (!value) { return ''; }
    
  hiddenPre.innerHTML = value.replace(/</g,"&lt;");
  // innerText depends on styling as it doesn't display hidden elements.
  // Therefore, it's better to use textContent not to cause unnecessary reflows.
  return hiddenPre.textContent;
}


var encoded = '&lt;p&gt;name&lt;/p&gt;&lt;p&gt;&lt;span style="font-size:xx-small;"&gt;ajde&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;em&gt;da&lt;/em&gt;&lt;/p&gt;';
var decoded = decodeEntities(encoded);

document.getElementById("encoded").innerText=encoded;
document.getElementById("decoded").innerText=decoded;

#encoded {
  color: green;
}

#decoded {
  color: red;
}

Encoded: <br/>
<div id="encoded">
</div>

<br/>
<br/>

Decoded: <br/>
<div id="decoded">
</div>
