Using AngularJS variables within JavaScript code

Question

Using AngularJS variables within JavaScript code

This is my introduction to using AngularJS.

The code snippet below displays the desired output:

<a href="http://www.example.com/xyz/{{life.animal}}/" target="_blank">Hello </a>

Upon clicking, it redirects to: http://www.example.com/xyz/cat/

However, the following code does not behave as expected:

<a href='javascript:void(0)' onClick='javascript:window.open("http://www.example.com/xyz/{{life.animal}}/","Windows","width=1150,height=450,toolbar=no,menubar=no,scrollbars=yes,resizable=yes,titlebar=no,location=no,directories=no,status=no");return false')'>Hello </a>

It directs to: http://www.example.com/xyz/{{life.animal}}/

I believe I might be making a fundamental error, so any assistance is greatly appreciated.

Answer №1

When working outside of Angular, the Angular scope is not accessible in vanilla JavaScript.

If you want to set a click function the Angular way, you should use ng-click.

To achieve this, create a function in your controller or directive like:


    scope.open = function() {
        $window.open(...)
    }

In your template, simply use:

ng-click="open()"

Angular doesn't have direct interaction with strings, but it seems like you are trying to make it work in your onclick handler that opens a new window (passing a string value). Instead of passing a string directly, concatenate the string with a variable:

onClick='javascript:window.open("http://www.example.com/xyz/" + life.animal)'

Additionally, as @Enzey suggested, use ng-click instead of onClick, and move the JavaScript functionality out of your HTML into a controller.

For example:

HTML

<a href="javascript:void(0)" ng-click="myFunction()">Foo</a>

Controller

$scope.myFunction = function() {
    window.open(...whatever...);
}

Angular directives make use of double hashes, while Javascript Vanilla does not. It's recommended to utilize ng-href instead of href in an <a> tag. For more information, you can refer to this resource.
