如何将值从javascript发送到php
How to send values form javascript to php
本文关键字：php javascript 更新时间：2023-09-26
我创建了两个文件，一个是html文件，另一个是php文件。我已经在java脚本中创建了一个数组。在java脚本中，我创建一个动态表，并从HTML文件中获取值并传递到数组中。我还创建了一个点击事件。每当从 html 页面单击按钮时，我都想将 java 脚本值或数组从 java 脚本发送到 php 页面。
在 php 中检索值时，不会显示这些值。请指导我。波纹管是我的代码。
var t = 0;

使用 .ajax() jquery 函数。这是相当不错的http://api.jquery.com/jQuery.ajax/
