Struggling with calling two functions within a single ng-init directive in AngularJS, but encountering errors. Here's my code:
ng-init="function1(); function2();"
I'm unsure of the correct way to call these functions. Any suggestions or ideas would be greatly appreciated.
Thanks in advance.
To streamline your code, consider organizing multiple functions within a single main function called "initialize". This way, you can easily call other functions from within this central function.
ng-init="initialize()"
This is an example of how you can structure the code in your controller:
function initialize() {
performTask1();
executeTask2();
}
Take a look at the link below and check out the console for more information.

HTML
<div ng-init='one(); two();'></div>
JS
$scope.one = function(){
console.log('one')
};
$scope.two = function(){
console.log('two')
};
I hope this meets your expectations.
Initially, you may encounter issues because the necessary functions are not accessible within the scope. Have you assigned an ng-controller to either this element or a parent element?
If so, ensure that these functions are explicitly defined in the scope:
.controller("MainCtrl", function($scope){
$scope.function1 = function(){...};
$scope.function2 = function(){...};
});
Furthermore, refrain from utilizing ng-init to trigger functions.
<div ng-controller="MainCtrl">
</div>
Instead, invoke these functions within the controller itself:
.controller("MainCtrl", function($scope){
function1();
function2();
function function1(){...};
function function2(){...};
});
Referencing the Angular documentation on ngInit:
The recommended usage of ngInit is solely for aliasing special properties of ngRepeat, demonstrated below. In all other cases, it’s advisable to use controllers instead of ngInit to initialize values within a scope.
