Php 使用Post的Ajax自动完成会导致；“连接已重置”；错误和；net:：ERR“u EMPTY”响应；控制台错误

您好，感谢您抽出时间阅读我的问题

我的网站托管在Godaddy上，我有“豪华Linux托管包”

我的网页使用一个简单的表单帮助用户找到市场，该表单使用JQuery、Ajax、PHP和MySQL来显示与其搜索词相关的建议

我在搜索字段中使用自动完成功能，这样当用户键入搜索词时，相关建议将显示在id为“list_area”的div中输入字段的下方

这些建议由JQuery和一个PHP脚本填充，该脚本通过AJAX“Post”方法（现在是AJAX方法，因为我想将错误记录到控制台中）提供搜索词

下面是在HTML页面中调用js脚本的地方：

<input autocomplete="off" type="text" 
class="form-control input-lg" name="market_search" 
id="market_search" placeholder="Enter a market name" 
onkeyup="autoComplete();">

这里是search_markets.php

<?php
include("connect_to_mysql.php");

$output = '';
$search_term = mysql_real_escape_string($_POST['search_term']);

$sql = mysql_query("
                    SELECT name FROM markets 
                    WHERE name LIKE '%$search_term%' 
                    ORDER BY name LIMIT 0,10
                   ");

$num_rows = mysql_num_rows($sql);

if($num_rows > 0){

    $output .= '<ul>';
    while($row = mysql_fetch_array($sql)){

        $market_name = $row['name'];
        $market_name = preg_replace('/\s{2,}/u', ' ', $market_name); // replaces large spaces with single space between words

        $output .='<li onclick="set_item(\''.str_replace("'", "\'", $market_name).'\');">'.$market_name.'</li>';
