<form name = "vote" action = "logicDB.PHP" method = "post">
                    <center>
                        <h3>Watch our videos above and share your opinion which manufacturer produces the best sport sedans</h3>                
                        <fieldset style = "width:60%;">
                            <legend>Choose a car:</legend>
                            <input type = "radio" name = "rc1" id = "radio-choice-1" value = "Audi"/>
                            <input type = "radio" name = "rc1" id = "radio-choice-2" value = "BMW"/>
                            <input type = "radio" name = "rc1" id = "radio-choice-3" value = "Mercedes"/>           
                        </fieldset>                 
                        <input value = "SUBMIT" type = "submit" />
                    </center>
</form>

表单的action参数调用我的PHP文件,该文件具有以下逻辑：

<?PHP
$connection = MysqL_connect("localhost","root","myPassword");
if(!$connection){ die('Could not connect: ' . MysqL_error()); }

MysqL_select_db("mydatabase",$connection);

if ($_POST['rc1'] == 'Audi')
{   
    MysqL_query("
    UPDATE carvote
    SET votes = votes + 1
    WHERE Brands = 'Audi'
    ",$connection);

    echo "success Audi within if";
}

if ($_POST['rc1'] == 'BMW')
{
    MysqL_query("
    UPDATE carvote
    SET votes = votes + 1
    WHERE Brands = 'BMW'
    ",$connection);

    echo "success BMW within if";
}

if ($_POST['rc1'] == 'Mercedes')
{
    MysqL_query("
    UPDATE carvote
    SET votes = votes + 1
    WHERE Brands = 'Mercedes'
    ",$connection);

    echo "success Mercedes within if";
}
MysqL_close($connection);
?>

我在我的WAMP localhost服务器上创建了一个数据库,这个PHP代码正在写入数据库,具体取决于从表单中选择和提交的无线电选项.从未达到过PHP中的这些回声.

问题是,当我点击提交时,我会在左上角看到一个白色的屏幕,显示“未定义”,之后没有任何内容写入数据库.我发现,如果我从html主页中删除调用顶部jQuery mobile的行
一切正常,数据写入数据库(到达PHP中的回声).
似乎jQuery mobile与我的PHP代码不兼容.我该怎么解决这个问题？
先感谢您！

更新(我使它工作)：
以下是我在表单中所做的更改：

<form id = "ContactForm" onsubmit="return submitForm();">

带有数据库的PHP文件保持不变.除此之外,我还添加了一个Ajax代码：

function submitForm()
    {
        $.ajax({type:'POST',url: 'logicDB.PHP',data:$('#ContactForm').serialize(),success: function(response)
        {
            $('#ContactForm').find('.form_result').html(response);
        }});
        return false;
    }

总结一下：jQuery Mobile页面(div中带有data-role =“page”的页面)只能通过AJAX提交.它不会起作用.
我会将主题更改为我的问题,以便更多人可以达到它.
