combobox reload

[ems2811]

Hello. Sorry for my English.

Code:

$('#cc').combobox({
	valueField: 'id',
	textField: 'name',
	mode: 'remote',
	method: 'get'
});
$('#cc').combo('options').delay=604800000;
$('#cc').combobox('options').selectOnNavigation=false;
$('#cc').combobox('textbox').bind('keyup',function(e){
	if (e.keyCode == 40){
		var _combo=$(this).parent().prev();
		_combo.combobox('reload','/Scripts/get_org.php?org_text='+_combo.combobox('getText'));
		_combo.combobox('showPanel');
	}
});

Enter text and press "alt" + "keydown" opens a drop-down list and the text in the edit is deleted. Then when you press the "down" there is no move through the panel, but called update (GET request) . Navigating the panel works by pressing the " down " . I do not correct or error in easyui?

Sorry. Code 40 belongs to the button down. It is only necessary to understand how to pass a combination.
Understood almost everything. Besides why erased text from the edit field in the call combobox ('reload')

Code:

$('#cc').combobox('textbox').bind("keyup",function(e){
	if (e.keyCode == 40 && e.altKey){
		var _combo=$(this).parent().prev();
		var _text=_combo.combobox('getText');
		_combo.combobox('reload','/Scripts/get_lpu.php?lpu_text='+_text)
		_combo.combobox('showPanel');
	}
});
