Could you paste your code?

$('#combo_id').combobox({
onSelect: function(record){
alert('onSelect'+record.text);
}
});

In case of copy/paste and press key enter very fast, it's not work.
The same as using Barcode reader to input in the combobox.

Please try to override the 'query' and 'enter' key handlers to let the combobox component accept the inputing value quickly.

Code:

$('...').combobox({
	url: ...,
	valueField: 'id',
	textField: 'text',
	onSelect: function(row){
		console.log(row)
	},
	keyHandler: $.extend({}, $.fn.combobox.defaults.keyHandler, {
		query: function(q){
			q = $.trim(q);
			var t = $(this);
			var opts = t.combobox('options');
			var panel = t.combobox('panel');
			var data = t.data('combobox').data;
			var item = $.easyui.getArrayItem(data, opts.textField, q);
			if (item){
				t.combobox('select', item[opts.valueField]);
			}
			panel.panel('close')
		},
		enter: function(e){
			var t = $(this);
			t.combobox('hidePanel');
		}
	})
})

It seems not working with Enter key.
It is just fire onSelect when the input data matched in the list.

Yes, it should match the data list. You can modify the 'query' code to fit your requirement.
