推荐答案

原答案:

在您的 .php 文件中.

In your .php file.

<script type="text/javascript"> 
  var team1, team2; 
  team1 = <?php echo $_GET['team1']; ?>; 
  team1 = <?php echo $_GET['team1']; ?>; 
</script>

更安全的答案:

当我爆出这个答案时，甚至没有考虑 XSS.(看评论！)$_GET 数组中的任何内容都应该转义，否则用户几乎可以将他们想要的任何 JS 插入到您的页面中.所以尝试这样的事情:

Didn't even think about XSS when I blasted this answer out. (Look at the comments!) Anything from the $_GET array should be escaped, otherwise a user can pretty much insert whatever JS they want into your page. So try something like this:

<script type="text/javascript"> 
  var team1, team2; 
  team1 = <?php echo htmlencode(json_encode($_GET['team1'])); ?>; 
  team1 = <?php echo htmlencode(json_encode($_GET['team1'])); ?>; 
</script>
