I have written a custom jquery autocomplete function to display certain values and textfields to update on selecting the value as per the code below:
<input type="text" name="promoitem" id="promoitem">
$('#promoitem').autocomplete({
source: "BckProcesses/GetPromoItems.asp",
create: function() {
$(this).data('ui-autocomplete')._renderItem = function(ul, item) {
return $('<li>')
.append('<a>' + item.promodesc + '</a>')
.appendTo(ul);
}
},
select: function(event, ui) {
$('#promoitem').val(ui.item.promodesc);
$('#promocost').val(ui.item.promocost);
$('#promoqty').val(ui.item.qty);
$('#hidden_promo_item_id').val(ui.item.id);
}
});
This is what is return by the source file (GetPromoItems.asp)
[{"id": "1", "promodesc": "Ipad 4 ", "promocost": "200", "qty": "1"},{"id": "2", "promodesc": "Village Tickets", "promocost": "20", "qty": "2"}]
However, when I select the value from the ul, everything gets populated except the promoitem textfield. That fields goes to being blank.
Can anyone please let me know what could be causing this?

Since you're providing your own logic in the
select
handler, you need to prevent the default action, which is to placeui.item.value
in theinput
.Right now, your code is running, and then jQueryUI is immediately trying to place
ui.item.value
in theinput
, which explains the empty value.So really all you need to do is call
event.preventDefault();
orreturn false;
from theselect
handler:
