在IE中，如果想打印frame中的内容，用window.print(frameId)好像不行，不过可以调用下面JS中的printFrame方法实现,即printFrame(frameId)~
<script language=“JScript“>
if ( printIsNativeSupport() )
window.print2 = window.print;
window.print = printFrame;
// main stuff
function printFrame(frame, onfinish) {
if ( !frame ) frame = window;
function execOnFinish() {
switch ( typeof(onfinish) ) {
case "string": execScript(onfinish); break;
case "function": onfinish();
}
if ( focused && !focused.disabled ) focused.focus();
}
if ( frame.document.readyState !== "complete" &&
!confirm("The document to print is not downloaded yet! Continue with printing?") )
{
execOnFinish();
return;
}
if ( window.print2 ) { // IE5
var focused = document.activeElement;
frame.focus();
if ( frame.print2 ) frame.print2();
else frame.print();
execOnFinish();
return;
}
var eventScope = printGetEventScope(frame);
var focused = document.activeElement;
window.printHelper = function() {
execScript("on error resume next: printWB.ExecWB 6, 1", "VBScript");
printFireEvent(frame, eventScope, "onafterprint");
printWB.outerHTML = "";
execOnFinish();
window.printHelper = null;
}
document.body.insertAdjacentHTML("beforeEnd",
"<object id=\"printWB\" width=0 height=0 classid=\"clsid:8856F961-340A-11D0-A96B-00C04FD705A2\"></object>");
printFireEvent(frame, eventScope, "onbeforeprint");
frame.focus();
window.printHelper = printHelper;
setTimeout("window.printHelper()", 0);
}
// helpers
function printIsNativeSupport() {
var agent = window.navigator.userAgent;
var i = agent.indexOf("MSIE ")+5;
return parseInt(agent.substr(i)) >= 5 && agent.indexOf("5.0b1") < 0;
}
function printFireEvent(frame, obj, name) {
var handler = obj[name];
switch ( typeof(handler) ) {
case "string": frame.execScript(handler); break;
case "function": handler();
}
}
function printGetEventScope(frame) {
var frameset = frame.document.all.tags("FRAMESET");
if ( frameset.length ) return frameset[0];
return frame.document.body;
}
</script>
