<body>

<p>

function copyToClipBoard(){

var clipBoardContent="";

clipBoardContent+=document.title;

clipBoardContent+="";

clipBoardContent+=this.location.href;

window.clipboardData.setData("Text",clipBoardContent);

alert("复制成功，请粘贴到你的QQ/MSN上推荐给你的好友");

}

</script>

<br />

直接复制url

function copyUrl()

{

var clipBoardContent=this.location.href;

window.clipboardData.setData("Text",clipBoardContent);

alert("复制成功!");

}

</script>

<br/>

点击文本框时,复制文本框里面的内容

function oCopy(obj){

obj.select();

js=obj.createTextRange();

js.execCommand("Copy")

alert("复制成功!");

}

</script>

<br />

复制文本框或者隐藏域中的内容

function CopyUrl(target){

target.value=myimg.value;

target.select();

js=myimg.createTextRange();

js.execCommand("Copy");

alert("复制成功!");

}

function AddImg(target){

target.value="[IMG]"+myimg.value+"[/ img]";

target.select();

js=target.createTextRange();

js.execCommand("Copy");

alert("复制成功!");

}

</script>

<br />

<br/>

复制span标记中的内容

</script>

<br />

{

var rng = document.body.createTextRange();

rng.moveToElementText(obj);

rng.scrollIntoView();

rng.select();

rng.execCommand("Copy");

rng.collapse(false);

alert("复制成功!");

}

//js 复制，保存，运行代码

function runcode(obj) {

var winname = window.open('', "_blank", '');

winname.document.open('text/html', 'replace');

winname.opener = null

winname.document.writeln(obj.value);

winname.document.close();

} //运行代码

function copycode(obj) {

var rng = document.body.createTextRange();

rng.moveToElementText(obj);

rng.scrollIntoView();

rng.select();

rng.execCommand("Copy");

rng.collapse(false);

} //复制代码

function savecode(obj) {

var winname = window.open('', '_blank', 'top=10000');

winname.document.open('text/html', 'replace');

winname.document.write(obj.value);

winname.document.execCommand('saveas','','code.htm');

winname.close();

}//保存代码

</script>

<span id="tbid">http://pmp.cnblogs.com</span>
