Unable to implement str.replace function within HTML code

Within my Angular app, I'm looking to replace all instances of _ within a string. In my controller, the following code achieves the desired outcome:

alert("this_is_string_".replace(/_/g, " "));

However, when attempting to implement the same code within my HTML file as shown below:

 <th class="text-center" ng-repeat="(key, value) in filteredEL[0] ">
    {{ key.replace(/_/g, ' ') }}
 </th>

An error is thrown:

Error: [$parse:syntax] Syntax Error: Token '/' not a primary expression at column 13 of the expression [key.replace(/_/g, ' ')] starting at [/_/g, ' ')]

How can I properly utilize the replace function to modify all necessary instances within the HTML?

One way to streamline your code is by creating a custom filter for removing underscores from strings:

angular.module('filters.stringUtils', [])

.filter('removeUnderscores', [function() {
    return function(string) {
        if (!angular.isString(string)) {
            return string;
        }
        return string.replace(/_/g, '');
    };
}])

Once the filter is defined, you can easily use it in your HTML like this:

<div id="{{'hi_there'| removeUnderscores}}"></div>

Utilizing the angular filter feature is considered the most effective method for filtering content within HTML.

For more information, check out the angular-filter documentation.

.filter('customFilter', ['$filter', function ($filter) {
    return function (input) {
      if (input) {
      return input.replace(/_/g, '');
      }
}
}])

<th class="text-center" ng-repeat="(key, value) in filteredEL[0] ">
    {{ key | customFilter}}
 </th>

A useful method to consider is split and join.

<td class="text-center" ng-repeat="(item, index) in filteredData[1] ">
