Event when deleting last character on input

[RobParticipant]

Hi,

Is it possible to receive an event when an input field has one character typed and when that character is deleted by the user?

I want to disable another button on a web page (or take other action) when an input field becomes empty.

i have tried the following but that function isn’t executed when the last (and only one) character is removed.

$("#searchInput").jqxInput({
                source: function (query, response) {
                    var item = query.split(/,\s*/).pop();
                    // loop throe all tree items
                    // if tree item not equal hide tree item otherwise keep visible
                    // If nothing found then enable AddTreeItemButton();
                }
            });

Thanks in advance,
Rob

Hello Rob,

You can use “change” event and check in event handler for your requirement.

hello Nadezhda,

Thanks for your quick reply. I have a handlers installed for the change event but that one only gets fired after pressing the enter key.
I like to have an event when the input fields become empty.

Thanks, Rob
