jQuery AutoComplete Trigger Change Event

Question

How do you trigger jQuery UI's AutoComplete change event handler programmatically?

Hookup

$("#CompanyList").autocomplete({ 
    source: context.companies, 
    change: handleCompanyChanged 
});

Misc Attempts Thus Far

$("#CompanyList").change();
$("#CompanyList").trigger("change");
$("#CompanyList").triggerHandler("change");

Based on other answers it should work:

JQuery Autocomplete help

The change event fires as expected when I manually interact with the AutoComplete input via browser; however I would like to programmatically trigger the change event in some cases.

What am I missing?

Answer 1

this will work,too

$("#CompanyList").autocomplete({
  source : yourSource,
  change : yourChangeHandler
})

// deprecated
//$("#CompanyList").data("autocomplete")._trigger("change")
// use this now
$("#CompanyList").data("ui-autocomplete")._trigger("change")

Answer 2

Here you go. It's a little messy but it works.

$(function () {  
  var companyList = $("#CompanyList").autocomplete({ 
      change: function() {
          alert('changed');
      }
   });
   companyList.autocomplete('option','change').call(companyList);
});

It's better to use the select event instead. The change event is bound to keydown as Wil said. So if you want to listen to change on selection use select like that.

$("#yourcomponent").autocomplete({  
    select: function(event, ui) {
        console.log(ui);
    }
});
