What is the proper way to reference "ng-bind-html" within a "title" element?

Question

What is the proper way to reference "ng-bind-html" within a "title" element?

I have been attempting to utilize the "ng-bind-html" directive within the "title" tag in order to display a currency value with its corresponding currency symbol, but unfortunately the expression is not being evaluated.

This is the approach I'm taking:

$scope.salary = 10000;
$scope.currencySymbol = '&#8364;';//€
<div title="{{ng-bind-html= 'salary |currency:(currencySymbol+' '): 0'}}"> //This is not working
<span ng-bind-html="salary |currency:(currencySymbol+' '): 0"> </span> //working fine and renders €10000

It works perfectly when displayed within a <span> tag, however I would like to also present the same formatted value within a <title> tag.

As a result, I'm left wondering how I can implement the use of the "ng-bind-html" directive within the "title" tag to achieve the same output as seen in the <span> tag?

Answer №1

ng-bind-html serves as a directive. Instead of using curly braces for expressions, a directive should be used separately.

To modify your expression, follow this format:

<div title="{{ salary | currency:currencySymbol: 0}}"></div>

Be sure to substitute the currencySymbol value with your desired currency prefix string. For example, set

$scope.currencySymbol = "€ ";

If you absolutely need to process your currency symbol dynamically and treat it as html, consider creating a custom currency filter that accepts an sceHtmlString. Since Javascript strings support unicode, it seems that specialized functionality may not be necessary in this particular scenario.

Here is a suggestion for you: You can include a title within the div element, but keep in mind that it will not be visible since the title attribute does not display as text.

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular-sanitize.js"></script>
<body>

<div ng-app="myApp" ng-controller="myCtrl">

<div ng-bind-html="myText"></div>
 <span>Currency Example:</span>
      <div> {{ salary | currency:currencySymbol: 0}} </div>
       <div title=" {{ salary | currency:currencySymbol: 0}}"> nodata</div>
     <span>Currency Example ng-bindhtml</span>
     <span ng-bind-html="myText"></span>
     <p ng-bind-html="myText"></p>
    </div>
</div>

<script>
var app = angular.module("myApp", ['ngSanitize']);
app.controller("myCtrl", function($scope) {
    $scope.myText = "My name is: <h1>  111 John Doe</h1>";
     $scope.salary = 10000;
   $scope.salaryhtml = "<p> €10000 </p>";
  $scope.currencySymbol = "€";
  $scope.myText ="  <h1>$ 1000 </h1>";
});
