Question

I would like to create the XML string on the the aspx page and then submit this request using the YUI ajax request to another aspx page for the processiong. So
1. is this possible by setting some of the ajax requests configurations like we do on ajax response ?
2. How it can be done ?

Answer 1

Yes, use YAHOO.util.Connect (http://developer.yahoo.com/yui/docs/YAHOO.util.Connect.html)

Code would go like:

var myXmlString = "<?xml version='1.0'?>"+
                  ...
;
var conn = YAHOO.util.Connect.asyncRequest ( 
    "POST", 
    "http://myhost/mypage.aspx", 
    {
        success: function(o) { 
            ...callback...
            // o.responseXML contains the response
        },
        error: function(o){
        }
    },
    myXmlString
);
