将js变量传递给php变量 [英] Passing js variable to php variable
问题描述
我想将刚刚单击的标签的id值传递给正在使用greybox加载到页面上的php文件.
I want to pass the id value of the tag that has just been clicked to a php file that is being loaded onto the page using greybox.
我将id存储在名为linkID的js变量中，并且可以使用location.href传递正确的ID，但这需要重新加载页面并且不能与greybox一起使用.我可以并且可能如何使用Ajax在后台帮助发送此信息?任何帮助将不胜感激?
I got the id stored in a js variable called linkID and I can get it passing the correct id using location.href but this needs a page reload and doesnt work alongside greybox. Can and maybe how can I use Ajax to help send this info in the background? Any help would be greatly appreciated?

}
</script>

}
function sud2(){
document.getElementById("rslt2").innerHTML="<?php
echo $phpvar;?>";
}
</script>
<body>
