XMLDataModel - processing data

[JasonMichael]

Hi, I understand its pretty easy to load XML data into a form, but I'm needing to just access data that I've loaded, and create a loop to make HTML 'select' options for a drop down menu. Off the top of your heads, anyone have a suggestion of where I might start? I've worked on this about an hour or so, and have been successful in using the XMLDataModel.grid to get data into memory from my web service api/AJAX proxy, but I'm such a newbie.... I'm very humbled by the whole Javascript/YUI-ext experience...

hmm I'm confused here...is the value for your drop down menu in the XML data for the grid? or will you make a completely different call for it?

if it's the second option I'd probably use an AsyncRequest like so:



var sUrl = 'yourUrl'
var params = 'params=popIt' ;
var callback = { success: function(o){
// o.responseText is the answer given by your url
var response = o.responseText;
// get a reference to your select box
var select = getEl('the-selec-id');
// I'd make the loop here to get to the corresponding childNode
},
failure: function(o){
alert('failed!')
};

YAHOO.util.Connect.asyncRequest('POST', sUrl, callback, params);
}

Hi Jack,

You're precisely correct - a different call, and I believe your solution here is going to work great. I'll try it out and let you know... maybe post it here for others to check out. Thanks again,

Actually, this solution would work if my data response wasn't an XML document... or then again, it would, but I was wondering if its possible to have multiple XML data models within one function. so far, Ive been getting some strange results.

I might be asking Javascript to do too much , as it would be easy enough to just have PHP create the option values for the drop down menu, then have a onselect call a function that would have the grid updated with a different set of data.
