jQuery AutoComplete Trigger Change Event

Question

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

Hookup

$(\"#CompanyList\").autocomplete({ 
    s         


        

Answer 1

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);
    }
});

Answer 2

Here is a relatively clean solution for others looking up this topic:

// run when eventlistener is triggered
$("#CompanyList").on( "autocompletechange", function(event,ui) {
   // post value to console for validation
   console.log($(this).val());
});

Per api.jqueryui.com/autocomplete/, this binds a function to the eventlistener. It is triggered both when the user selects a value from the autocomplete list and when they manually type in a value. The trigger fires when the field loses focus.

Answer 3

The programmatically trigger to call the autocomplete.change event is via a namespaced trigger on the source select element.

$("#CompanyList").trigger("blur.autocomplete");

Within version 1.8 of jquery UI..

.bind( "blur.autocomplete", function( event ) {
    if ( self.options.disabled ) {
        return;
    }

    clearTimeout( self.searching );
    // clicks on the menu (or a button to trigger a search) will cause a blur event
    self.closing = setTimeout(function() {
        self.close( event );
        self._change( event );
    }, 150 );
});

Answer 4

Another solution than the previous ones:

//With trigger
$("#CompanyList").trigger("keydown");

//With the autocomplete API
$("#CompanyList").autocomplete("search");

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);
});

I was trying to do the same, but without keeping a variable of autocomplete. I walk throught this calling change handler programatically on the select event, you only need to worry about the actual value of input.

$("#CompanyList").autocomplete({ 
    source: context.companies, 
    change: handleCompanyChanged,
    select: function(event,ui){
        $("#CompanyList").trigger('blur');
        $("#CompanyList").val(ui.item.value);
        handleCompanyChanged();
    }
});
