I have encountered an issue where I am unable to access my angular controller's scope outside of the controller. This problem arises when using an external JavaScript library that performs certain actions and executes callbacks upon completion. In one of the callbacks,
angular.element(document.findElementById('elementId').scope()undefined. However, in a subsequent callback that is executed after the first, the same code snippet returns the valid scope.
Below is a snippet of sample code for reference:
<body id="authcontroller" ng-controller="AuthenticationController as auth">
<script>
window.externalLibObj = {
onCallback1: function(){
// Scope is undefined
var scope = angular.element(document.getElementById('authcontroller")).scope();
},
onCallback2(): function(){
// Scope has a valid value
var scope = angular.element(document.getElementById('authcontroller")).scope();
}
};
</script>
</body>
The order of execution for these callbacks is onCallback1 followed by onCallback2. The variable scope is found to be undefined in onCallback1, but contains a value in onCallback2.
This prompts the question: Why is scope undefined in onCallback1?
Any assistance on this matter would be greatly appreciated. Thank you.
