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？

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。

<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(); 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>
