感谢大家对我上一个问题的大力帮助。

现在我又遇到了问题。

问题：我正在使用模型表单提交密码。在提交模型表单时，我想将操作称为$ _POST或$ _REQUEST。但我无法在PHP代码中获得发布操作。下面是我的代码

文件名：password.php 

          <?php
            // i try both method
            if($_SERVER['REQUEST_METHOD'] == 'POST')
            {
            var_dump($_REQUEST['data']); die;
            }

            /*if($_REQUEST['data'])
            {
                $password=$_REQUEST['data'];   

                var_dump($password);
             die;
            }*/
            ?>

使用ajax时，您似乎忘了将收到的响应添加到网页中。表单已提交，但您没有看到网页中的更改，因为您实际上没有指定应对数据执行的操作。您可以使用$(#elementID).html(html_)为收到的数据设置元素的内部HTML，假设elementID是您要放置数据的元素ID，而html_是收到的数据来自ajax。

示例

假设存在名称 adq.php 的文件，以下内容应该有效，ID dialog-form的元素是您要将其内部HTML更改为从ajax和您要提交的数据是RePassword.val()。

$.ajax({
    type: "POST",
    url : 'adq.php',
    data: {password: RePassword.val()},                                     
    success: function(e)
    {
       $("#dialog-form").html(e); 
       // console.log("successfull");
    }
});

注意您还应该使用PHP中的$_REQUEST['password']来获取提交的值，而不是$_REQUEST['data']，因为HTML中指示的字段名称为password而不是data Jon所述。
