Title: draggable init bug
Post by: BegeMode on April 22, 2013, 11:52:03 PM

create a draggable element that initially he disabled.

Code:

$('.selector').draggable({
                            revert:true,
                            disabled: true,
                            proxy: .....
                            .......
                        });

if the 'disabled == true', $.data(this, "draggable") is empty, see fragment of code:

Code:

if(_32.disabled==true){
$(this).css("cursor","");
return;
}
var _34=null;
if(typeof _32.handle=="undefined"||_32.handle==null){
_34=$(this);
}else{
_34=(typeof _32.handle=="string"?$(_32.handle,this):_32.handle);
}
$.data(this,"draggable",{options:_32,handle:_34});

then I make it enabled, event handlers and proxy need to be defined again

if initially draggable element is disabled, it is not initialised !!!
why is this happening can be seen from the source:

Code:

	$.fn.draggable = function(options, param){
		if (typeof options == 'string'){
			return $.fn.draggable.methods[options](this, param);
		}
....................

			if (opts.disabled == true) {
				$(this).css('cursor', '');
//				$(this).css('cursor', 'default');
				return;
			}
.....................

initialization occurs below:

Code:

var handle = null;
            if (typeof opts.handle == 'undefined' || opts.handle == null){
                handle = $(this);
            } else {
                handle = (typeof opts.handle == 'string' ? $(opts.handle, this) : opts.handle);
            }
			$.data(this, 'draggable', {
				options: opts,
				handle: handle
			});

this is bug or feature?

no reaction ((((
EasyUI a good framework, but the lack of response to the detected errors can not make it better (((
