Hi Folks,
I'm pretty sure that I'm going to be told to go back to school here,
but I've wasted a whole morning trying to figure this out - now it's
time to ask the experts.
I've simplified my code here to demonstrate what I'm trying to do:
[CODE]
var buildPage = {};
buildPage = Class.create();
buildPage.prototype =
{
initialize: function() {
this.rowTemplate = '<tr>...'
this.rs = [];
this._getData();
},// initialize
_getData : function() {//using AJAX to grab a JSON array from the
server and store it in this.rs
},
_parseTemplate : function() {//write data to screen then add event
listeners
$$('.editable').invoke('observe', 'mouseover',function(e){e.element
().addClassName('pseudo-text-box')});
$$('.editable').invoke('observe', 'mouseout',function(e){e.element
().removeClassName('pseudo-text-box')});
$$('.editable').invoke('observe', 'click', function(e)
{this._editField.bindAsEventListener(this, e) });
},
_editField : function(e) {
//Inject <INPUT> field
}
};
[/CODE]
My problem is with this line:
$$('.editable').invoke('observe', 'click', function(e)
{this._editField.bindAsEventListener(this, e) });
At runtime, I always get the message that this._editField is not a
function, no matter how I try the binding. The only way I can get
this to work is to initiate the class (var a = new buildPage) than
call c._editField from within the function - but that's not much good
when I come to re-use it.
Can someone explain to me what's going on here - I'm stumped.
Many thanks
George
