JavaScript JQuery UI Autocomplete: Response, Ctrl + A and Backspace jquery autocomplete response example,jquery autocomplete response format,jquery autocomplete

I'm working on a form to add members to a project. Only members whose profiles are recorded in the system can be added. There are a name input field and a position select box. The position select box by default is disabled.

The idea:

  • User types a name, autocomplete dropdown appears. The dropdown contains names of members whose profiles are recorded in the system.

  • User picks a name in the dropdown, the position select box will undisabled.

  • If after this, user makes any change to the name input field, the position select box is disabled again and the autocomplete dropdown appears again.

I put the disabled events into the response event of the autocomplete.

Problem: When I put Backspace to the input field, the position select box is disabled. But when I put Ctrl + A then Backspace, it isn't. How can I fix this?

$("#autocomplete").autocomplete({
    source: function(request, response) {
        //some ajax stuffs
    }, 
    select: function (e, ui) {
        $('#verified').val('true'); //the name is already recorded 
        $('#selectPosition').removeAttr('disabled');
    },
    response: function(event, ui) {
        if($('#verified').val() == 'true') {
            $('#verified').val('');
            $('#selectPosition').attr('disabled','disabled');
        }
    }
})

The .change() method fires when there is a change in the input box. This change is detected when the focus moves out of the input box. It works regardless of how the change was made - whether you use backspace to remove a character/characters, or you use Ctrl + A to select the entire text and remove it using backspace. The event will fire when you move the focus out of the input box.
