问题描述

可能重复：

如何将javascript变量放入php echo

我有JavaScript来获取时间，代码如下。

I have JavaScript to get time and the code is below.

<script type="text/javascript">

var d = new Date();

var H = d.getHours();
var m = d.getMinutes();
if(H>11)
{
    var h = H-12;
    var a = 'PM';
}
else
{
    var h = H;
    var a = 'AM';
}

</script>

现在，我想打印PHP中使用的变量，例如，

Now, I want to print the variables in PHP that used in JavaScript like,

<?php echo $h.$m; ?>

有可能吗？

如果是的话然后帮助我。

if yes then help me.

推荐答案

Javascipt在客户端上运行，php在服务器上运行...
如果你只是想在浏览器中打印var

Javascipt runs on the client, php runs on the server... If you just want to print the var in the browser

var varName = "varValue";
document.write(varName);

如果你需要将javascript var发送到php，你需要用jquery将它发送到服务器或javscript然后返回数据...

if you need to send the javascript var to php, you need to send it to the server with jquery or javscript and then return the data...

$.post("yourFile.php", { varName: "varValue" },
function(data) {
   //print the data coming from yourFile.php
   document.write(data);

}）;

如果您只需要将var发送到服务器

if you only need to send the var to the server

 $.post("yourFile.php", { hour: "hour", min: "min", sec:"sec" } );
