Question

how can i access an array, defined in the form, inside javascript.
e.g
i have defined an integer array inside the web form like

<%  using (Html.BeginForm())
   {
       int[] ctid = ViewData["ct"] as int[];
       var x = 0;    
       %>

now i want to access this array(ctid) inside javascript, how can i do that…

Answer 1

You’ll need to loop through the array and write it out to a Javascript array.

%>
//page JavaScript
var js_ctid = new Array(<% =ctid.length %>);

<%

//C# code
for (int=0; i<ctid.length; i++)
{
    Response.Write("js_ctid[" + i + "] = " + js_ctid[i]);
} 

You could also try the JavaScriptSerializer Class (http://msdn.microsoft.com/en-us/library/system.web.script.serialization.javascriptserializer.aspx) to turn it into a JSON object
