This Plunker demonstration is a great visual guide: http://plnkr.co/edit/y3uacaQSc1MbrWKfb0At?p=preview
Here's the code snippet for reference:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope,testFactory) {
$scope.name = 'World';
var test_var = "iceland";
$scope.testFunction = testFactory.testFunction;
});
app.service('testFactory',function(){
this.testFunction = function(){
alert(test_var);
};
})
In the HTML section:
<body ng-controller="MainCtrl">
<p ng-click="testFunction()">Hello {{name}}!</p>
</body>
The current issue, as observed in the Plunkr example, is that `test_var` is undefined which is expected as it has not been defined. To resolve this, there is an intention to pass it from the controller without executing the function. However, directly assigning `scpe.testFunction = testFactory.testFunction(test_var);` results in immediate execution due to the parentheses. The goal here is to only pass `test_var` without triggering the function. How can this be achieved?
