Global Functions in AngularJs
Hello everyone, I am going to share the code sample to create the global functions available in every controller.
Hello everyone, I am going to share the code sample to create the global functions available in every controller.
Here in AngularJs,
have two options for creating global functions. i.e.
1. Define a service for global function.
2. Using run method for root scope.
Here,
I am going to use the $rootScope and app.run()
on initialization in AngularJs as given below example.
The live demo link http://embed.plnkr.co/lQfOiX/preview
//This is global functions
for every controller.
app.run(function ($rootScope) {
$rootScope.myGlobalFunction = function () {
};
});
The AngularJs code-sample
var app =
angular.module('myApp',
[]);
//This is global functions
for every controller.
app.run(function ($rootScope,
$window) {
$rootScope.myGlobalFunction = function () {
//TODO : your custom code
here.
$window.alert('I am global
function. :)');
console.log("I am global
function. :)");
};
});
//This is controller for
accessing to global functions.
app.controller('MainCtrl', function ($scope) {
//TODO: your controller code
here.
});
The HTML code-sample
<div ng-app="myApp" ng-controller="MainCtrl">
<div ng-init="myGlobalFunction()">
<button ng-click="myGlobalFunction()">Click and call
global function</button>
</div>
</div>
The Live demo
code (HTML + AngularJs) as given below.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<link rel="stylesheet" href="style.css" />
<script src="https://code.angularjs.org/1.4.3/angular.js"></script>
<script>
var app =
angular.module('myApp',
[]);
//This is global functions
for every controller.
app.run(function ($rootScope,
$window) {
$rootScope.myGlobalFunction = function () {
//TODO : your custom code
here.
$window.alert('I am global
function. :)');
console.log("I am global
function. :)");
};
});
//This is controller for
accessing to global functions.
app.controller('MainCtrl', function ($scope) {
//TODO: your controller code
here.
});
</script>
</head>
<body ng-app="myApp" ng-controller="MainCtrl">
<p class="txt">Global Functions in
AngularJs</p>
<div ng-init="myGlobalFunction()">
<p>
<a href="http://code-sample.com/">Click for know about
me. :)</a>
</p>
<button class="btn" ng-click="myGlobalFunction()">Click and call
global function</button>
</div>
</body>
</html>
