如何将JavaScript函数数据转换为PHP变量

Question

我正在使用PHP和JavaScript。我的JavaScript代码包含一个函数get_data（）：

function get_Data(){

    var name;

    var job;

    .....

    return buffer;

}

现在我有以下PHP代码。

<?php

    $i=0;

    $buffer_data;

    /* Here I need to get the value from JavaScript get_data() of buffer;

       and assign to variable $buffer_data. */

?>

如何将JavaScript函数数据分配给PHP变量？

Answer 1

使用jQuery将JavaScript变量发送到您的PHP文件：$url = 'path/to/phpFile.php';$.get($url, {name: get_name(), job: get_job()});在你的PHP代码，让你的变量从$_GET['name']与$_GET['job']这样的：<?php&nbsp; &nbsp; $buffer_data['name'] = $_GET['name'];&nbsp; &nbsp; $buffer_data['job']&nbsp; = $_GET['job'];?>

Answer 2

JavaScript代码在客户端执行，而PHP在服务器端执行，因此您必须将JavaScript值发送到服务器。这可能被塞进Ajax$_POST或通过Ajax塞进去。
