$(function() {
  $("input").autocomplete({

  });
});

Autocomplete from remote data

Ajax

use ajax for getting data from server

<script>
$('#remote_input').autocomplete({
  valueKey:'title',
  source:[]
});
$('button#open').click(function(){
  $('#remote_input').trigger('open');
  $('#remote_input').focus();
});
</script>

or use custom function

$("#remote_input1").autocomplete({
 source:[
  function( q,add ){
   $.getJSON("index.php?s="+encodeURIComponent(q),function(resp){
    add(resp.data)
   })
  }
 ]
});

or combain static with dinamic variants

$('#remote_input2').autocomplete({source:[
 {
  url:"/component/jquery_plugins/?task=demodata&q=%QUERY%",
  type:'remote'
 },
 ["One","Two","Three"]
]});

You can use not only array, you can use object

$('#remote_input2').autocomplete({source:[{
 data:[
  {id:1, title:"alabama"},
  {id:2, title:"alaska"},
  {id:3, title:"georgia"},
  {id:4, title:"texas"},
  {id:6, title:"california"}
 ],
 getTitle:function(item){
  return item['title']
 },
 getValue:function(item){
  return item['title']
 },
}]}).on('selected.xdsoft',function(e,datum){
 alert(datum.id);
 alert(datum.title);
});
