Using regular JavaScript with code inside ng-view in AngularJS involves incorporating event listeners and manipulations that can interact

Just delving into the world of angularJS for the first time. I've set up the routing service, which involves having a div with routing that calls in a template containing HTML code. I also have a range of regular JavaScript functions necessary for the code in the template to display correctly (such as slideshows and various other components).

However, when I run the code, I encounter null errors indicating that my JS functions are unable to locate certain elements. This could be due to them not being able to access the code in the ng-view or the template not loading before they are executed.

I did manage to get it working by placing all of my JavaScript functions in the controller assigned to that template. But I suspect this may not be the correct approach. What is the proper method to ensure everything works smoothly? Thank you.


var app = angular.module("myApp", ["ngRoute"]);
app.config(function($routeProvider){
    $routeProvider
    .when("/",{
        templateUrl:"about.html",
        controller:"aboutCtrl"
    })
    .when("/aboutus", {
        templateUrl:"entertainment.html"
    })
});

app.controller('aboutCtrl', function($scope){
    // Regular JavaScript/jQuery code placed here to ensure functionality
});

Your jQuery functions may not be working properly because the elements they need to target cannot be found when you are on a different page.

Here are some ways to address this issue:

  • The cleanest solution would be to encapsulate your slideshow functionality in an Angular directive. This allows you to define the HTML template and associated code for the slideshow, which will only be executed when the template is rendered. If you are new to Angular, you might need some additional guidance on implementing this.
  • Another option is to include your JavaScript code directly within the template using a tag. This ensures that the code is only run when the template is loaded.
  • While it is possible to place the code in your controller, this can clutter the controller and make the code harder to maintain.

Although options 2 and 3 may work, they have the potential to complicate your app as it grows. I highly recommend exploring Angular directives further to keep your code organized and efficient.
