Retrieving JavaScript array data following a page reload

I am facing an issue with updating an array dynamically in my C# server-side code and then utilizing the updated data in a JQuery function on my webpage. When the page first loads, the array is filled with some default values by C#. However, when a user makes changes to a control triggering a postback, the C# code refills the array with the correct updated data. Despite confirming through Firebug that the data has been updated, I still see the original array contents displayed.

For example: Upon initial page load, this is how the array is populated:

<script>
  function pageLoad() {
    var ary= new Array('original-1','original-2', 'original-3', 'original-4');
  }
</script>

After the postback, the array is updated as follows (confirmed through Firebug inspection):

<script>
  function pageLoad() {
    var ary= new Array('updated-1','updated-2', 'updated-3', 'updated-4');
  }
</script>

Despite successfully loading the updated content, I continue to see the original data instead of the updated values.

My query is: How can I access and use the updated data after the postback? I believe there might be a simple solution to this problem, but I am struggling to figure it out.

Answer №1

Make sure to declare your variable `ary` as an empty array outside of the function to give it global visibility.


    <script>
    var ary = [];
    function pageLoad() {
        ary = ['original-1', 'original-2', 'original-3', 'original-4'];
    }
    </script>
