Does Dojo xhrPost / xhrGet has an equivalent callback function as jQuery beforeSend?
You can use dojo/aspect
.
aspect.before(dojo, "xhrGet", function(args){
args.url = 'index.html?TEST';
return [args];
});
var btn = new Button({label: 'xhr'}, 'btn');
on(btn, 'click', function(evt){
var xhrArgs = {
url: "index.html",
handleAs: "text",
load: function(data){ console.debug(data); },
error: function(error){ console.error(error);}
}
dojo.xhrGet(xhrArgs);
});
