javascript - How to split a string with angularJS

Question

I wanted to know if I can split a string simply in angularJS. I have my

 $scope.test = "test1,test2";

in my controller and in my view, I wanted to do something like that

{{test[0] | split(',')}}
{{test[1] | split(',')}}

I've seen a lot thing about input and ng-change calling a function in the controller that split the string or something with ng-list but nothing works in my case.

thx to all.

You may want to wrap that functionality up into a filter, this way you don't have to put the mySplit function in all of your controllers. For example

angular.module('myModule', [])
    .filter('split', function() {
        return function(input, splitChar, splitIndex) {
            // do some bounds checking here to ensure it has that index
            return input.split(splitChar)[splitIndex];
        }
    });

From here, you can use a filter as you originally intended

{{test | split:',':0}}
{{test | split:',':0}}
