我正在创建一个应该显示倒计时的网页，如果它为零，则应该在新的截止日期之前开始下一个倒计时。 现在，我已经在Javascript中做了倒计时部分，这是有效的。
我已经做了一个PHP的一部分，读取最后期限形成一个txt文件，这也适用。
现在我已经找到了一种将php截止日期转换为javascript的方式，应该可以工作。
但是。 下一个截止日期必须在上一个完成时开始，因此它是00:00:00。 有没有办法在php中检查html div的内容？ 因此，它将不得不检查是否与ID =倒数div的内容等于00:00:00如果html div等于某个值，则在PHP中检查
谢谢你们！ 编辑：命题重复的问题并没有解决我的问题......

我想你会想做一个AJAX调用，并将div的内容发送到一个php脚本进行解析/处理。 – raphael75
