Hi there!
[cuts]
loadTemplates: function() {
for(var name in this.templates) {
var f = function (func,args){ return function(args2){
func(args,args2) } }(this.onTemplateLoad.bind(this),name);
new Ajax.Request(this.templates[name].url, {method:''get'',
onComplete: f });
}
},
onTemplateLoad: function(name,originalRequest) {
alert(name+": "+originalRequest.responseText);
},
[cuts]
that''s the only way I''ve found to pass additional parameters
to
Ajax.Request callbacks.
Anyone sees a cleaner way?

Hey Alessandro, Alessandro Curci a écrit :> var f = function (func,args){ return function(args2){ > func(args,args2) } }(this.onTemplateLoad.bind(this),name); > new Ajax.Request(this.templates[name].url, {method:''get'', > onComplete: f });This should cut it: new Ajax.Request(this.templates[name].url, { method: ''get'', onComplete: this.onTemplateLoad.bind(this, name) }); The bind method takes additional arguments that are prefixed to those occurring upon actual invocation. Since Ajax.Request will invoke your callbacks by passing it the original request first, your name here will appear first, and the transport second.> onTemplateLoad: function(name,originalRequest) { > alert(name+": "+originalRequest.responseText); > },You''ll even get a third argument, evalJSON, a boolean based on the X-JSON HTTP response header. Oh, and BTW, make sure your "this.templates" object is not an array, but an anonymous object of some sort: arrays have plenty of Prototype-induced extensions, so the for/in loop would be inappropriate in your case.
