window.print打印指定div实例代码

window.print可以打印网页，但有时候我们只希望打印特定控件或内容，怎么办呢，请看下面的例子

首先我们可以把要打印的内容放在div中，然后用下面的代码进行打印。

复制代码代码如下:

<html>
<head>
<script language="javascript">
function printdiv(printpage)
{
var headstr = "<html><head><title></title></head><body>";
var footstr = "</body>";
var newstr = document.all.item(printpage).innerHTML;
var oldstr = document.body.innerHTML;
document.body.innerHTML = headstr+newstr+footstr;
window.print(); // www.jbxue.com
document.body.innerHTML = oldstr;
return false;
}
</script>
<title>div print</title>
</head>

<body>

//HTML Page
//Other content you wouldn't like to print
<input name="b_print" type="button" class="ipt"   onClick="printdiv('div_print');" value=" Print ">

<div id="div_print">

<h1 style="Color:Red">The Div content which you want to print</h1>

</div>
//Other content you wouldn't like to print
//Other content you wouldn't like to print
</body>

</html>
