How to only used DataProcessor

hello,
The DataProcessor was must to be init(same Object for dhtmlx)?

I want to only used DataProcessor to send same data,how to do?

var dp = new dataProcessor(“php/update.php”);?
what is senddata dataformat or parameter?

If you want to make an arbitrary ajax call, it will be better to use dhx4.ajax methods instead.
docs.dhtmlx.com/api__dhtmlxajax_post.html

If you need to send some data along with normal dataprocessor packages, you can embed the data directly in the URL

var dp = new dataProcessor("php/update.php?data=abc&other=123");
