What about storing the callback explicitly in your object, so you don't have to worry about closure scopes:
var Obj =
{ func: function (callback) {
//this.callback = callback;
$.ajax(
{ type: 'POST'
, url: '/func'
, success: $.proxy(this.funcSuccess, this, callback)
, error: $.proxy(this.funcError, this)
}
)
}
, funcSuccess: function (callback, res) {
callback(res.thing)
}
, funcError: function (res) {
debug(res)
}
}
Edit: I forgot to bind the callbacks to this
. In JQuery you can do it with $.proxy
, see changes above.
Edit: A further tidy (jQuery 1.6 allows for this) with passing the callback as an argument to $.proxy
, so no need to attach it to the current object.
