window.print打印指定div
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。
代码如下:



function printdiv(printpage)
{
var headstr = "";
var footstr = "";
var newstr = document.all.item(printpage).innerHTML;
var oldstr = document.body.innerHTML;
document.body.innerHTML = headstr+newstr+footstr;
window.print();
document.body.innerHTML = oldstr;
return false;
}

//HTML Page
//Other content you wouldn't like to print

The Div content which you want to print

//Other content you wouldn't like to print
//Other content you wouldn't like to print
