Ajax总是出错

Question

我试图调用ajax但它总是出错部分。请帮帮我告诉我哪里错了。我也尝试在文本文件中写入最终值，它很完美但不知道为什么它不起作用。我还检查了URL也是正确的。

PHP代码：

public function checkLockBeforeSend()
{
    $mail_key = $_POST['mail_key'];

    $this->load->model('dl_master/email_compose');
    $result = $this->model_dl_master_email_compose->checkLock($mail_key);

    if($result['isopen'] == 1 && $result['openedby'] != $_SESSION['user_id'])
    {
        $this->load->model('dl_common/commonutil');
        $userResult = $this->model_dl_common_commonutil->getUserById($result['openedby']);
        $userName = $userResult['firstname'] . " " . $userResult['lastname'];
        $html = $userName;
    }
    else
    {
        $html = "Empty";
    }

    /* Just to check what value is coming */
    $fp = fopen("C:\\test.txt","w");
    fwrite($fp,$html);
    fclose($fp);

    echo $html;
}

Ajax功能：

function checkLockBeforeSend(mail_key)
{
    var ajaxUrl = "index.php?route=dl_master/email_compose/checkLockBeforeSend&token=" + token;

    $.ajax ({
        url:ajaxUrl,
        type:'post',
        dataType: 'html',
        data:{'mail_key':mail_key},
        success:function (result)
        {
            alert(result);
            if(result.trim() != "Empty")
            {
                 finalResult = confirm(result);
            }
        },
        error: function () 
        {
            alert("An error occurred.");
        }
    });


}

请帮帮我。

请尝试data:{mail_key:mail_key},而不是data:{'mail_key':mail_key},。
