Answer 1

<script language="javascript">// example 1
function getParameter($varName)
{
    var $query = location.search;
    if ($query != null || $query != "")
    {
        $query = $query.replace(/^\?+/, "");
        var $qArray = $query.split("&");
        var $len = $qArray.length;
        if ($len > 0)
        {
            for (var $i=0; $i<$len; $i++)
            {
                var $sArray = $qArray[$i].split("=", 2);
                if ($sArray[0] && $sArray[1] && $sArray[0] == $varName)
                {
                    return unescape($sArray[1]);
                }
            }
        }
    }
    return null;
}alert(getParameter('act'));// example 2
String.prototype.getQuery = function(name)
{
    var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
    var r = this.substr(this.indexOf("\?")+1).match(reg);
    if (r!=null) return unescape(r[2]); return null;
}
var url = document.URL;
alert(url.getQuery("act"));
</script>

哦，我没说清楚，我JS文件是这样的，我想在JS文件里放置一个hidden区域，hidden值就来自于js传过来的ID参数。这个是JS页面：document.write("<table width=99%  border=1 cellpadding=0 cellspacing=0 bordercolor=#7FCFF5>");
document.write("            <tr>");
document.write("              <td height=127 align=left valign=top bordercolor=#FFFFFF><table width=100% height=147  border=0 cellpadding=0 cellspacing=0>");
document.write("                  <tr>");
document.write("                    <td height=18 align=left valign=middle bgcolor=#7FCFF5><table width=100%  border=0 cellspacing=0 cellpadding=0>");
document.write("                        <tr align=center valign=middle>");
document.write("                          <td width=4% bgcolor=#3EBBF0><img src=/images/news/pencil.gif width=18 height=18></td>");
document.write("                          <td width=96% align=left bgcolor=#3EBBF0 class=Bottom-b>发表评论</td>");
document.write("                        </tr>");
document.write("                    </table></td>");
document.write("                  </tr>");
document.write("                  <tr>");
document.write("                    <td height=25><table width=55%  border=0 cellspacing=0 cellpadding=0>");
document.write("                        <tr>");
document.write("                          <td width=2% height=18 align=center valign=middle>&nbsp;</td>");
document.write("                          <td width=8% align=left valign=middle class=biaoti>签名</td>");
document.write("                          <td width=90%><input type=text name=username /></td>");
document.write("                        </tr>");
document.write("                    </table></td>");
document.write("                  </tr>");
document.write("                  <tr>");
document.write("                    <td height=25><table width=55%  border=0 cellspacing=0 cellpadding=0>");
document.write("                        <tr>");
document.write("                          <td width=2% height=18 align=center valign=middle>&nbsp;</td>");
document.write("                          <td width=8% align=left valign=middle class=biaoti>标题</td>");
document.write("                          <td width=90%><input type=text name=username /></td>");
document.write("                        </tr>");
document.write("                    </table></td>");
document.write("                  </tr>");
document.write("                  <tr>");
document.write("                    <td height=28 align=left valign=top><table width=42%  border=0 cellspacing=0 cellpadding=0>");
document.write("                        <tr>");
document.write("                          <td width=2% height=18 align=center valign=middle>&nbsp;</td>");
document.write("                          <td align=left valign=middle class=style25><textarea name=content cols=40 rows=6></textarea></td>");
document.write("                        </tr>");
document.write("                    </table></td>");
document.write("                  </tr>");
document.write("                  <tr>");
document.write("                    <td height=28 align=left valign=top><table width=42%  border=0 cellspacing=0 cellpadding=0>");
document.write("                        <tr>");
document.write("                          <td width=2% height=38 align=center valign=middle>&nbsp;</td>");
document.write("                          <td width=56% align=left valign=middle class=style25><img src=/images/news/post.jpg width=68 height=22></td>");
document.write("                          <td width=42% align=right valign=middle class=style25><img src=/images/news/post1.gif width=68 height=22></td>");
document.write("                        </tr>");
document.write("                    </table></td>");
document.write("                  </tr>");
document.write("              </table></td>");
document.write("            </tr>");
document.write("        </table>");

Answer 3

<script src="/js/reply.php?id=1"></script>用php生成js代码replay.php里这样取:echo "var getid=".$_GET["id"].";\n";

Answer 4

自找麻烦
test.php
<script>
id = 1;
</script>
<script src="/js/reply.js"></script>这样在reply.js中就可以使用变量id了

Answer 5

xuzuning(唠叨) 老大，呵呵我是举个例的啊，我的id值是会变化的，不定的你还有什么解决方法吗，谢了哦

Answer 6

id值是会变化的，不定的--------------------------
<?php
echo "<script>id=".$id.";</script>";
?>
<script src="/js/reply.js"></script>

Answer 7

直接载入reply.php不行吗？不就是载入一些全局的js函数吗，reply.php里面按照js规范写好，不也可以用吗,而reply.php后面加些参数可以吧，或者把.js用php解析下行不行？
