[jQuery] Re: AjaxCFC

[Brook Davies]

Thanks for the feecback Jack. I am using the success() method and within
that method I want to call a method on the current object. The reason is
because I have spawned multiple objects and they all fetch data via ajaxCFC
and I want the correct object to handle the result. 

 

I could save a reference in the global scope, but that would mean I could
only have one ajax call at a time. I just wish I could pass an object
through to the callback handler so that reference would be available in
success(). I guess I could pass a string reference to the class object to
the server and have it returned an evaluated - but there must be a better
way, no?

Hmm, maybe create a global var to hold a ref to the scope?

var currentObj;

and in getData:

    currentObj = this;
    ajax call

and in dataResult:

    currentObj.someProperty = data.yadda;
    currentObj = null;

?

In case you don't know, the ajaxCFC also has a success callback:

$.AjaxCFC({
    url: some.cfc,
    method: 'doIt',
    data: { yadda:'ya' },
    success: function(data){
        do some stuff;
    }
});

I'm assuming you're calling the dataResult() function via the success
attribute, but just in case, FYI. It doesn't really change the approach to
knowing scope thing, though, AFAIK. If you try putting "this" inside the
anonymous function, it still won't know the calling object.

Hello Jack,

 

Well  I want to get the scope of the calling object that the function
resides in. I have multiple instances of this object:

 

someObj = {

 

getData: function(){

            

            //cfAjax request starts here

            

}

,

 

dataResult: function(data){

            // handle result from cfAjax here

}

 

}

 

a = new someObj()

b = new someObj()

 

// call getData on 'a' instance

a.getData();

 

This is where I want the cfAjax callback to be within the scope of the 'a'
object or at least somehow get a reference to 'a'. How do I do that?
