Problem with Converting C# Objects into JavaScript

I need help transferring a double array from C# to JavaScript dynamically. Currently, I am using the following approach:

var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
var jsLat = serializer.Serialize(lat);

After that, I use InvokeScript with jsLat as a parameter.

When trying lat.length on the JS side, I get the correct length. However, when attempting lat[#], all values return as undefined.

Additionally, utilizing alert(lat.valueOf()) shows all the values. Why is it that all values are appearing as undefined?

Answer №1

When working with JavaScript, it's important to familiarize yourself with the JSON.parse function, which is supported by most modern browsers. If you need compatibility with older browsers like IE6/IE7, there are alternative JavaScript implementations available (see http://json.org for more information).

  var result = JSON.parse("{lat:1234, lon:567"})

For users of jQuery, there is a convenient alternative in the form of jQuery.parseJSON, which offers browser support across the board.
