php ajax成功:函数(msg) -获取msg

I have some jquery/php code which uses ajax to call another page.

我有一些jquery/php代码，它使用ajax调用另一个页面。

var pall_id = $(this).attr('id');
        $.ajax({ 
           type: "POST",
           url: "do_history.php?pall_id="+pall_id,   
           success: function (msg) {
                alert (msg);

            },
            error: function (XMLHttpRequest, textStatus, errorThrown)
            {   
                alert('Error submitting request.'); 
            } 
        });

However what do I do to get the value of msg? e.g. if do_history.php is simply:

然而，我怎么做才能得到味精的价值呢?例如,如果do_history。php是简单的:

<?php

$text="text";
return $text;

?>

would 'msg' not be "text" so when I alert(msg); I would get "text" popping up on my screen.

“msg”不是“text”，所以我提醒(msg);我会在屏幕上弹出“文本”。

What do I need to do to return a string value? Any ideas?

要返回一个字符串值，我需要做什么?什么好主意吗?

Thanks,

谢谢,

Use echo $text; and in your $.ajax options add dataType: 'text'.

使用echo $文本;和你的美元。ajax选项添加数据类型:“文本”。

However, a better solution would be using dataType: 'json' and then echo json_encode($text); - in this case $text could also be an array/object/number and it would be the appropriate type in the JavaScript function .

但是，更好的解决方案是使用数据类型:'json'，然后回显json_encode($text);在这种情况下，$text也可以是一个数组/对象/数字，它将是JavaScript函数中适当的类型。
