我想寻求一些帮助，我的代码，因为我目前的代码不会工作…我发现这个插件代码从这个网站…到现在为止，所有都不工作，甚至第一个组合框过滤…谁能帮我得到这个代码的工作请

index.php：

<!DOCTYPE html>
<html>
<head>
<title>test</title>
<script type="text/javascript" src="jquery/jquery-1.11.0.min.js"></script>
<script type="text/javascript" src="jquery.jCombo.min.js"></script>

<body>
<form>
<select name="position" id="position"></select>
<select name="salary_grade" id="salary_grade"></select>
<select name="salary" id="salary"></select>
</form>
<script type="text/javascript">
$( document ).ready(function() { 
   $("#position").jCombo({ url: "getPosition.php", selected_value : '150' } );
    $("#salary_grade").jCombo({ url: "getSalary_Grade.php?sgid=",
                    parent: "#position",
                    selected_value: '178'
                });     
    $("#salary").jCombo({ url: "getSalary.php?salaryid=",
                    parent: "#salary_grade",
                    selected_value: '630'
                });
});
</script>
</body>
</html>


测试
$（文档）.ready（函数（）{
$（“#position”）.jCombo（{url:“getPosition.php”，选择_值：'150'}）；
$（“#薪资等级”）.jCombo（{url:“getSalary_grade.php？sgid=”，
父项：“位置”，
所选的_值：“178”
});     
$（“#salary”）.jCombo（{url:“getSalary.php？salaryid=”，
家长：“工资等级”，
所选的_值：“630”
});
});

getPosition.php：

<?php

    // Connect Database
    mysql_connect("localhost","root","");     
    mysql_select_db("test");

    // Execute Query in the right order  
    //(value,text)
    $query = "SELECT tcode, position FROM positions";
    $result = mysql_query($query);
    $items = array();
    if($result && mysql_num_rows($result)>0) {
        while($row = mysql_fetch_array($result)) {
            $option = array("id" => $row[0], "value" => htmlentities($row[1]));
            $items[] = $option; 
        }        
    }
    mysql_close();
    $data = json_encode($items); 
    // convert into JSON format and print
    $response = isset($_GET['callback'])?$_GET['callback']."(".$data.")":$data; 
    echo $data;
?>

getSalary_Grade.php：

<?php

    // Connect Database 
    mysql_connect("localhost","root","");     
    mysql_select_db("test");

    // Get parameters from Array
    $sgid = !empty($_GET['tcode'])
              ?intval($_GET['tcode']):0;

    // if there is no city selected by GET, fetch all rows    
    $query = "SELECT id,salary FROM salary_grades WHERE salary_grades.id = '$sgid'"; 

    //  fetch the results
    $result = mysql_query($query);
    $items = array();
    if($result && mysql_num_rows($result)>0) {
        while($row = mysql_fetch_array($result)) {
            $option = array("id" => $row[0], "value" => htmlentities($row[1]));
            $items[] = $option; 
        }        
    } 
    mysql_close();
    $data = json_encode($items); 
    $response = isset($_GET['callback'])?$_GET['callback']."(".$data.")":$data; 
    $cache->finish($response);  
?>

这应该可以：
getSalary.php
// Connect Database 
mysql_connect("localhost","root",""); 
mysql_select_db("klayton"); 

// Get parameters from Array 
$salaryid = !empty($_GET['salaryid']) 
?intval($_GET['salaryid']):0; 

// if there is no city selected by GET, fetch all rows 
$query = "SELECT id,salary FROM salarys WHERE id = $salaryid"; 

// fetch the results 
$result = mysql_query($query); 
$items = array(); 
if($result && mysql_num_rows($result)>0) { 
while($row = mysql_fetch_array($result)) { 
$option = array("id" => $row['id'], "value" => htmlentities($row['salary'])); 
$items[] = $option; 
} 
}

<?php 

// Connect Database 
mysql_connect("localhost","root",""); 
mysql_select_db("klayton"); 

// Get parameters from Array 
$sgid = !empty($_GET['sgid']) 
?intval($_GET['sgid']):0;

// if there is no city selected by GET, fetch all rows 
$query = "SELECT id, salary FROM salary_grades WHERE id = $sgid"; 

// fetch the results 
$result = mysql_query($query); 
$items = array(); 
if($result && mysql_num_rows($result)>0) { 
while($row = mysql_fetch_array($result)) { 
$option = array("id" => $row['id'], "value" => htmlentities($row['salary'])); 
$items[] = $option; 
} 
}

getSalary\u Grades.php
// Connect Database 
mysql_connect("localhost","root",""); 
mysql_select_db("klayton"); 

// Get parameters from Array 
$salaryid = !empty($_GET['salaryid']) 
?intval($_GET['salaryid']):0; 

// if there is no city selected by GET, fetch all rows 
$query = "SELECT id,salary FROM salarys WHERE id = $salaryid"; 

// fetch the results 
$result = mysql_query($query); 
$items = array(); 
if($result && mysql_num_rows($result)>0) { 
while($row = mysql_fetch_array($result)) { 
$option = array("id" => $row['id'], "value" => htmlentities($row['salary'])); 
$items[] = $option; 
} 
}

<?php 

// Connect Database 
mysql_connect("localhost","root",""); 
mysql_select_db("klayton"); 

// Get parameters from Array 
$sgid = !empty($_GET['sgid']) 
?intval($_GET['sgid']):0;

// if there is no city selected by GET, fetch all rows 
$query = "SELECT id, salary FROM salary_grades WHERE id = $sgid"; 

// fetch the results 
$result = mysql_query($query); 
$items = array(); 
if($result && mysql_num_rows($result)>0) { 
while($row = mysql_fetch_array($result)) { 
$option = array("id" => $row['id'], "value" => htmlentities($row['salary'])); 
$items[] = $option; 
} 
}

您希望它与上一个示例（嵌套组合）一样吗？脚本是否至少在第一个示例中选择了默认选项？另外，getSalary.php中的$\u GET['tcode']
不应该是$\u GET['sgid']
和$\u GET['id']
吗
？你在两个地方编辑jquery.jCombo.min.js了吗？它在脚本的两个地方写着数据类型：'jsonp'
。谢谢你的天才；D
