Hello,

I am new to JSON and I am using the prototype library by the way.

the data that a recieve from my ajax query looks like this
{'0':'string1','1':'string2'}

I will not know any of the elements at query time but what I do need to do is find out the number of elements and to be able to iterate throught them to get all of the values.

How do I do that using JSON notation.

Thanks,

David

<script type="text/javascript">
var result=null;

//...
eval("result=" + JSONString + ";");
if(result)
{
 for( var i in result )
  alert( i + "=" + result[i] );
}
where the "..." is the code that makes the request to the server and JSONString is the data you are getting from the server in JSON format.
