请教JS参数如何赋给PHP ??

<br />
<br />
function getSig(openid,openkey,url,pf){<br />
  <br />
 var sigStr="<?php echo get_sig('"+openid+"','"+openkey+"','"+url+"','"+pf+"') ?>";<br />
<br />
}<br />


getSig括号里的参数如何赋给PHP的get_sig ? 
我里面怎么写都不行。。请教方法
------解决方案--------------------
php是在服务器端执行完才把页面返回到浏览器执行js,js里的参数没有办法直接赋值到php里面。
只能发ajax请求。
