this is the code its working fine in desktop but not in mobile when i click with mouse it does not work but when i use arrow to slect and press enter then it works but not in select please help me out with this

_{EDIT by @mgol: code formatting fixed}

Start with the provided document handler for #location and reproduce the jQuery UI autocomplete behavior on a mobile device, comparing tap selection with keyboard selection. Trace why tapping a suggestion does not invoke the select path; done when tapping a city updates #locality, #lat, #lng, and #country and performs the location update just as Enter does.
