1. 調用frmae 執行print命令 idFrame.document.execCommand('print');
源碼：
<html>
<head>
<title>
</title>
<style>
html { font: 9pt / 13pt Verdana; color: black }
input { font: 9pt Verdana; color: black; width: 115pt }
input.ie55 { display: none }
body { background-color: gainsboro; padding: 10pt }
li { margin-top: 4pt }
p { margin-top: 6pt; margin-bottom: 6pt }
h2 { font:bold 16pt / 18pt Verdana }
</style>
<!-- special style sheet for printing -->
<style media="print">
.noprint { display: none }
</style>
</head>
<body>
<object id="WebBrowser" width=0 height=0 classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"></object>
<SCRIPT language=javascript>
function printpr() //打印預覽 、
{
var obj=document.getElementById("idFrame");
obj.focus();
WebBrowser.ExecWB(7,1);
}
function pagesetup() //頁面設置
{
var obj=document.getElementById("idFrame");
obj.focus();
WebBrowser.ExecWB(8,1);
}
function printTrue() //打印
{
var obj=document.getElementById("idFrame");
obj.focus();
idFrame.document.execCommand('print');
}
</SCRIPT>
<div id=idControls class="noprint">
<input type="button" onClick="printpr();" value="打印預覽">
<input type="button" onClick="pagesetup();" value="頁面設置">
<input type="button" onClick="printTrue();" value="打印">
<input type="button" value="關閉窗口" οnclick="window.close();">
</div>
<iframe name="idFrame" width="100%" src="http://www.163.com" frameborder="0" id="idFrame" scrolling="no"
marginheight="0" marginwidth="0" οnlοad="this.height=idFrame.document.body.scrollHeight"></iframe>
</body>
</html>
2.直接 window.print();
function printDoc()
{
document.getElementById("printbtn").style.display = "none";
document.getElementById("closebtn").style.display = "none";
window.print();
document.getElementById("printbtn").style.display = "";
document.getElementById("closebtn").style.display = "";
}
