2、在当前网页echo出变量$_SERVER['PHP_SELF']即可获取网页地址。

3、在当前网页echo出变量$_SERVER["QUERY_STRING"]即可获取网址参数。

4、在当前网页echo出变量$_SERVER['>

5、在当前网页echo出变量$_SERVER['>

6、也是点上，用个变量保存好输出。

码一：

<script>

function selecturl(){

z=documentbodycreateTextRange();

zmoveToElementText(selecturlDiv);

zselect();

}

</script>

<span onmousemove='selecturl()' id=selecturlDiv><script>documentwrite(locationhref)</script>

代码二：

<script>

function copyCode(o){oselect();var js=ocreateTextRange();jsexecCommand("Copy");alert("复制成功！");}

documentwrite("<table align=center class=tableborder1 cellpadding=1 cellspacing=0><tr>");

documentwrite("<td width=10% nowrap class=tablebody1>本页URL地址（双击复制）：</td>");

documentwrite("<td class=tablebody1><textarea onfocus=thisselect() style='width:100%;overflow-y:visible;' ondblclick=copyCode(this) rows=1>");

documentwrite(selflocation+"</textarea></td></tr></table>");

</script>

代码三：

<script language="javascript">

<!--

function copyToClipBoard(){

var clipBoardContent=documentlocation;

clipBoardContent+='\r\n';

windowclipboardDatasetData("Text",clipBoardContent);

alert("耶！复制成功喽！你可以粘贴在QQ消息里送给你的好朋友呀！再次感谢你对 的支持哦！");

}

//-->

</script>

<script language='javascript'>

documentwrite("<img src=\"templates//images/dbgif\" width=\"49\" height=\"17\">");

documentwrite("<input size=\"60\" value=\""+documentlocation+"\"><input type=\"button\" value=\"推荐给朋友\" title=\"点击复制地址到剪贴板,直接在MSN/QQ上粘贴即可\" onclick=\"copyToClipBoard()\">");

</script>
