I know the code I have developed (see below) can be achieved with the
use of link:chain as a request option, but at the time I wrote it, I
didn't realise you could change the url of a Request. I have a case
where it is guaranteed to chain (I call the function callRequest
inside the onCompletion function of a request) and in Google Chrome it
stopped working. I decided to upgrade to mootools 1.3, and now it
doesn't work at all in Firefox either (although I also have an
upgraded version of Firefox - v4).
The problem is related to the the parameters of the chained function,
in that when it is called from the chain they are all undefined. The
code is below and I suspect the problem is related to my use of
auguments.callee and bind - could someone tell me what I am doing
wrong
Queue: new Class({
initialize: function(myURL) {
this.pageURL = myURL;
this.queue = new Chain();
this.running = false;
this.requests = {};
this.reCall = null;
},
callRequest:function (myUrl,myParams,bind,myCallback) {
var that = this;
if(this.requests[myUrl] == undefined) {
this.requests[myUrl] = new Request ({
url:myUrl,
onSuccess: function(html) {
var holder = new
Element('div').set('html',html);
if (holder.getElement('error')) {
alert(holder.getElement('error').get('text'));
window.location = that.pageURL;
} else {
that.reCall(holder);
that.running = false;
that.queue.callChain();
}
}
});
}
if (this.running) {
this.queue.chain(arguments.callee.bind(this,
[myUrl,myParams,bind,myCallback]));
} else {
this.running = true;
var calling = myCallback.bind(bind)
this.reCall = calling;
this.requests[myUrl].post(myParams);
}
}
})
