Help to submit xml string/document as ajax request to background page using YUI

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
);

See the docs for detailed infop

Answer 2

xml is passed using following code snippet. It can also be used to pass the JSON data.
YAHOO.util.Connect.setDefaultPostHeader(false);
YAHOO.util.Connect.initHeader("Content-Type", "application/xml; charset=utf-8");
var myXmlString = 'TEST DATA';
var conn = YAHOO.util.Connect.asyncRequest (
"POST",
"BackgroundPage.aspx",
{
success: function(o) {
div.innerHTML = "Success" + o.responseText;
},
error: function(o){
div.innerHTML = "Error";
}
},
myXmlString
);
