$ _REQUEST ['id']从一个由javascript调用到另一个php页面的php文件中的页面

Question

I'm trying to get the value 3 from this link: index.php?subtopic=example&id=3 Normally I would use the $_REQUEST['id'] but I'm facing another situation here.

I got the example1.php:

<script type="text/javascript" src="js/chatbox.js"></script>
...
<div id="chat_box"></div>

And then the chatbox.js:

setInterval( function() {
$('#chat_box').load('chatbox.php');
} , 100 );

And finally the chatbox.php:

echo $_REQUEST['id'];

but I can't get the id value here :/ Please Help!!!

Basically you want to parse the id out of the URL and send it to the chat - let's do this:

<script type="text/javascript">
  function getID() {
    var tmp=location.href.split('?');
    if (tmp.length!=2) return -2;
    tmp=tmp[1].split('&');
    for (i=0;i<tmp.length;i++) {
      var param=tmp[i].split('=');
      if (param.length!=2) continue;
      if (param[0]!="id") continue;
      return parseInt(param[1]);
    }
    return -3;
  }

  var chaturl='chatbox.php?id='+getID();

</script>
<script type="text/javascript" src="js/chatbox.js"></script>
...
<div id="chat_box"></div>

...

setInterval( function() {
$('#chat_box').load(chaturl);
} , 100 );
