Issue: Unable to use the b.replace function as it is not recognized (first time encountering this error)

I can't seem to figure out what I'm doing wrong. It feels like such a silly mistake, and I was hoping someone could lend a hand in solving it.

Here is my controller - I'm utilizing ng-file-upload, where Upload is sourced from:

.controller('main', ['$scope', 'Upload', '$timeout', function ($scope, Upload, $timeout) {

    $scope.shareLink = false;

}]);

and this is my template

<i id="share_mail" ng-click="shareLink = !shareLink" ng-style="!shareLink ? 'opacity:0.5;' : ''" class="fa fa-envelope-o"></i>

Error message

Error: name.
    replace is not a function. (In 'name.
    replace(SPECIAL_CHARS_REGEXP, function(_, separator, letter, offset) {
      return offset ? letter.toUpperCase() : letter;
    })', 'name.
    replace' is undefined)

Answer №1

To improve your code, it's recommended that you switch out the ng-style directive with ng-class. Here is how you can implement it:

<i id="share_mail" ng-click="shareLink = !shareLink" ng-class="{'add-opacity': !shareLink}" class="fa fa-envelope-o"></i>

In your CSS file, add the following styling for the new class:

.add-opacity {
  opacity: 0.5; 
}

Answer №2

Modify the line containing ng-style to resemble one of these options -

ng-style="!shareLink && {'opacity' : 0.5}"

or

ng-style="!shareLink ? {'opacity' : 0.5} : ''"

Essentially, you are instructing Angular to assess the expression inside the {} curly braces.

Check out this functional demonstration -

var app = angular.module('test', [])

app.controller('main', ['$scope', '$timeout',
  function($scope, $timeout) {

    $scope.shareLink = false;
    $scope.shareLink2 = false;

  }
]);
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="test">
  <div id="test" ng-controller="main">
    <i id="share_mail" ng-click="shareLink = !shareLink" ng-style="!shareLink && {'opacity' : 0.5} " class="fa fa-envelope-o"></i>
    <i id="share_mail2" ng-click="shareLink2 = !shareLink2" ng-style="!shareLink2 ? {'opacity' : 0.5} : ''" class="fa fa-envelope-o"></i>
  </div>
</div>

I'd also suggest delving into Angular expressions, employing ternary operators, etc.
