jQuery val() for array of strings

Question

I'm very new to jQuery and its uses, but I'm trying to do something simple...I have a hidden input that contains a list of strings and I'm trying to put it into an AngularJS controller.

here's my input

<input type="hidden" id="states" value="{!states}" />

and code from my controller

$scope.states = jQuery('#states').val();

yet when I try something like alert($scope.states[0]) the alert box only contains "[", as if the first element in the states array is [, second element is A, third element is L, etc.

am I doing something wrong?

why do you need a hidden input in the first place when working with angular? — charlietfl

@charlietfl I'm trying to grab the value from the server. Not really sure how to do it otherwise. — Embattled Swag

would normally make a $http request and pass response to controller — charlietfl

@EmbattledSwag, usually, if you use jquery inside angular controlller - you do something wrong :-) try see this post “Thinking in AngularJS” if I have a jQuery background? — Grundy

sidenote: attribute value always is string. so for getting js object, you need parse this string. — Grundy

You need to transform the value from a string into an array. Try with JSON.parse():

$scope.states = JSON.parse(jQuery('#states').val());

this helped, but I also had to serialize the object on the server side too. Thanks!
