html代码:
<button onclick="testPrint('printDiv');">打印</button>
<div id="printDiv">此处为打印内容</div>
js代码
function testPrint(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;
}
大功告成
