AngularJS – How to call function on page load example with demo?

ng-init in Angular :: ng-init should use for only aliasing, ng-init SHOULD NOT be used for any initialization.

onload in Angular :: onload should be used if any expression needs to be evaluated after a partial view is loaded (by ng-include).

Angular onLoad vs ng-ini :: The major AND most important difference between onLoad and ng-init is when used with ng-include.

In this following case, pakainfo_function is called everytime the partial view is loaded(Angular onLoad vs ng-ini).

<div ng-include="pakainfoViewUrl" onload="pakainfo_function()"></div>

Whereas, in this following case, pakainfo_function is called only once when the parent view is loaded with onload angularjs.

<div ng-include="pakainfoViewUrl" ng-init="pakainfo_function()"></div>

The ng-init operate as shown in over code wont work as is. The operate outlined in ng-int ought to be within the angular context. over focusOnInput() is not within the angular context . It’s in javascript context.

if we wish to use ng-init we will need to inject angularjs onload $window into over controller then use assign focusOnInput to over $scope and use that methodology in ng-init.

ng-init could be a directive that may be placed within div, span, other(html tags), whereas onload is an attribute specific to the ng-include directive that functions as an ng-init. to envision what I mean attempt one thing like:

Angularjs onLoad vs ng-ini

<!-- Angularjs onLoad vs ng-ini -->
{{ pakainfoA }}
{{ pakainfoB }}

angularjs execute function on page load

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.2/angular.min.js"></script>
<div data-ng-init="init()">
<h2>Angularjs call function on page load - www.pakainfo.com</h2>
</div>
<script type="text/javascript">
		var fbApp = angular.module("fbApp", []);		

		fbApp.controller("callFunctionCtrl", function($scope, $window) {

			$scope.init = function () {
			 	alert("Angularjs call function on page load");
  			};

		});

	</script>

Angularjs call function on page load

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.2/angular.min.js"></script>
<div>
<h2>Angularjs call function on page load - www.pakainfo.com</h2>
</div>
<script type="text/javascript">
		var fbApp = angular.module("fbApp", []);		
		fbApp.controller("callFunctionCtrl", function($scope, $window) {


			$window.onload = function() {
			 	alert("Angularjs call function on page load");
			};


		});

	</script>

Example of onload : Angularjs page load

<form name="passwordResetForm"><input name="MemberChangeConfirmPass" type="password" /></form><script>
   function pakainfofocusOnInput() {
	  document.forms["passwordResetForm"]["MemberChangeConfirmPass"].focus();
   }
</script>

Example of Angular ng-init : Angularjs page load

<form name="passwordResetForm"><input name="MemberChangeConfirmPass" type="password" /></form><script>
   function pakainfofocusOnInput() {
	  document.forms["passwordResetForm"]["MemberChangeConfirmPass"].focus();
   }
</script>

we will see that only the second shows up for Angularjs onLoad vs ng-ini.

An isolated scope could be a scope that doesn’t prototypically inherit from its parent scope.

In laymen’s terms if you’ve got a gismo that does not got to scan and write to the parent scope arbitrarily then you utilize an isolate scope on the gismo in order that the gismo and gismo instrumentation will freely use their scopes while not predominant every other’s properties.
