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？

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:

";
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;
}

div print

//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
