這裏是jQuery用戶界面自動完成文件：

http://jqueryui.com/autocomplete/

這裏是它應該如何實現一個例子：

var AutoCompleteOptions = { source: function(request, response) { 
    $.ajax({ 
     url: 'your URL here', 
     dataType: "json", 
     data: { 
      itemToSearch: request.term // could be any data you are passing in for search 
     }, 
     success: function(data) { 
      // do something where search values are returned 
     },         
    }); 
    }, 
    select: $.proxy(function(event, ui){ 
     // what you want to do with that information 
     // using a proxy to preserve the reference to 'this' 
     return false; // prevent the default response (typically inserting the selected value into the textbox the dropdown is being displayed from. 
    },this), 
    open: function(event, ui) { 
     // things to do when the dropdown is rendered 
     return false; // prevent default autocomplete open action 
    }, 
    focus: function(event, ui) { 
     // what to do when an the user hovers over an item in the drop down 
     return false; // prevent default autocomplete open action 
    }, 
    minLength:0 // be sure to set this if you want to be able to trigger the search event manually and have it display results 
    }; 

var Input = $("input"); 

Input.autocomplete(this.AutoCompleteOptions)

你可以使用jQuery自動完成，包括庫和依賴文件，按照它應該出現的順序 here is autocomplete

PHP代碼

public function cities() { 

    $term = $_GET['term']; 
    $cities = array("one","two","three");// contains value fetched from DB 
    $filtered = array(); 
    foreach ($cities as $city) { 
     if (stripos($city, $term) !== false) { 
     array_push($filtered, $city); 
     } 
    } 
    echo json_encode($filtered); 
    exit; 
    } 

jQuery代碼

<script> 
    $(function() { 
    function log(message) { 
     $("<div>").text(message).prependTo("#log"); 
     $("#log").scrollTop(0); 
    } 

    $("#textboxid").autocomplete({ 
     source: "cities", 
     minLength: 2, 
     select: function(event, ui) { 
     log(ui.item ? 
      "Selected: " + ui.item.value + " aka " + ui.item.id : 
      "Nothing selected, input was " + this.value); 
     } 
    }); 
    }); 
</script>
