我正在建立一个网站来学习编码，并且我有一个基于 Jquery ui 的自动完成功能，我正在填充三个 mysql 表。

这是我在 index.php 上的代码（我的搜索框所在的页面和自动完成功能应该打开）

    <script src="./public/js/jquery.js"></script>
    <script src="public/js/jquery-ui-1.8.22.custom.min.js" type="text/javascript" charset="utf-8"></script>
    <script>
    $(function() {

            $("#search").autocomplete({
            source: "suggest.php",
            minLength = 2,
            select: function( event, ui ) {
                    log( ui.item ?
                         "Selected: " + ui.item.value + aka " + ui.item.id :
                         "Nothing selected, input was " + this.value );
                    }
            });

    });
    </script>

下面是 index.php 上的代码，即形式：

<form class="form-search span8 offset6">
    <input type="text" id='search' name='q' autocomplete="off" class="input-medium search-query">
    <button type="submit" class="btn btn-warning">GO!</button>
</form>

这是Suggest.php上的代码：

<?php

require("./config.php");

$q = $_GET['q'];

$names = '';

$result = mysql_query("SELECT name FROM company WHERE name LIKE '$q%' UNION SELECT cat FROM cat WHERE cat LIKE '$q%' UNION SELECT subcat FROM subcat WHERE subcat LIKE '$q%' LIMIT 10");

$names = array();

while ($row = mysql_fetch_array($result)) { 
   $names[] = $row['name']; 
}

echo json_encode($names);
?>

如果我直接访问Suggest.php?q= SOMETHING并回显$names，结果如下：

["City Market","Cafes","Cheesesteaks","Chicken Wings","Chinese","CSA","Coffee & Tea","Convenience Stores","Comedy Clubs"]Array

当我在 Chrome 中打开开发人员面板时，jQUery 旁边有一个错误，自动提示说“Uncaught SyntaxError: Unexpected Token =”

我的自动建议没有出现。怎么了？

感谢大家的帮助！

我将 = 更改为 : 现在新错误是“Unexpected Token Illegal”并且自动完成仍然没有出现......有什么建议吗？

你在 minLength 中有一个等号，应该是冒号

$(function() {

        $("#search").autocomplete({
        source: "suggest.php",
        minLength: 2,
        select: function( event, ui ) {
                log( ui.item ?
                     "Selected: " + ui.item.value + aka " + ui.item.id :
                     "Nothing selected, input was " + this.value );
                }
        });

});
