Detect when the input value changed if the user clicked a suggestion or not

[lmammino]

Is there a built-in way to detect, when the input changes, whether the user clicked a suggestion or not?

I looked at the code and i found the field value is set before calling the onSelect callback.

            //...
    select: function (i) {
        var selectedValue, f;
        selectedValue = this.suggestions[i];
        if (selectedValue) {
            this.el.val(selectedValue);
            if (this.options.autoSubmit) {
                f = this.el.parents('form');
                if (f.length > 0) { f.get(0).submit(); }
            }
            this.ignoreValueChange = true;
            this.hide();
            this.onSelect(i);
        }
    },
           //...

If the onSelect is called before the this.el.val(selectedValue) one would easily detect if the user selected a suggestion on change doing something like this:

$('.autocomplete').autocomplete({
    serviceUrl : '/ajax/autocomplete',
    onSelect : function(value, data, input)
    {
        input.data('suggestionClicked', true);
    }
});

$('.autocomplete').change(function(){
    if($(this).data('suggestionClicked')
    {
          // ...
    }
});

Please let me know if there's a built-in proper way to do so

Thanks

Hello Luciano,

There two methods on of them is onSelect and another is onChange

onSelect: function (value, data) {
…
},
onChange: function(value, data) {
if (data == -1) {
…..
}
},

Thanks

Thanks @Vytautas-Pranskunas .
Anyway the onChange calback is just a wrapper for the input default change event callback.
I mean It's called before the onSelect... so my problem persists...

Now i digged further into your code and discovered that your onChange function will pass a -1 as value for the data parameter when nothing has been selected. So this way I'm able to detect whether the user selected a suggestion or not.

Closing this issue. Thanks anyway!
