因?yàn)闃I(yè)務(wù)系統(tǒng)的特殊性，在web程序中經(jīng)常使用modal dialog，但是showModalDialog只能在IE中使用，于是又麻煩google，終于找到了解決方案： javascript modal dialog.
為了記憶，把demo的代碼抄錄：
<html>
<script language=JavaScript>
var ModalDialogWindow;
var ModalDialogInterval;
var ModalDialog = new Object;
ModalDialog.value = '';
ModalDialog.eventhandler = '';
function ModalDialogMaintainFocus()
{
try
{
if (ModalDialogWindow.closed)
{
window.clearInterval(ModalDialogInterval);
eval(ModalDialog.eventhandler);
return;
}
ModalDialogWindow.focus();
}
catch (everything) { }
}
function ModalDialogRemoveWatch()
{
ModalDialog.value = '';
ModalDialog.eventhandler = '';
}
function ModalDialogShow(Title,BodyText,Buttons,EventHandler)
{
ModalDialogRemoveWatch();
ModalDialog.eventhandler = EventHandler;
var args='width=350,height=125,left=325,top=300,toolbar=0,';
args+='location=0,status=0,menubar=0,scrollbars=1,resizable=0';
ModalDialogWindow=window.open("","",args);
ModalDialogWindow.document.open();
ModalDialogWindow.document.write('<html>');
ModalDialogWindow.document.write('<head>');
ModalDialogWindow.document.write('<title>' + Title + '</title>');
ModalDialogWindow.document.write('<script' + ' language=JavaScript>');
ModalDialogWindow.document.write('function CloseForm(Response) ');
ModalDialogWindow.document.write('{ ');
ModalDialogWindow.document.write(' window.opener.ModalDialog.value = Response; ');
ModalDialogWindow.document.write(' window.close(); ');
ModalDialogWindow.document.write('} ');
ModalDialogWindow.document.write('</script' + '>');
ModalDialogWindow.document.write('</head>');
ModalDialogWindow.document.write('<body onblur="window.focus();">');
ModalDialogWindow.document.write('<table border=0 width="95%" align=center cellspacing=0 cellpadding=2>');
ModalDialogWindow.document.write('<tr><td align=left>' + BodyText + '</td></tr>');
ModalDialogWindow.document.write('<tr><td align=left><br></td></tr>');
ModalDialogWindow.document.write('<tr><td align=center>' + Buttons + '</td></tr>');
ModalDialogWindow.document.write('</body>');
ModalDialogWindow.document.write('</html>');
ModalDialogWindow.document.close();
ModalDialogWindow.focus();
ModalDialogInterval = window.setInterval("ModalDialogMaintainFocus()",5);
}
</script>
<script language=JavaScript>
function YesNoCancel(BodyText,EventHandler)
{
var Buttons='';
Buttons = '<a href=javascript:CloseForm("Yes");>Yes</a> ';
Buttons += '<a href=javascript:CloseForm("No");>No</a> ';
Buttons += '<a href=javascript:CloseForm("Cancel");>Cancel</a> ';
ModalDialogShow("Dialog",BodyText,Buttons,EventHandler);
}
function YesNoMaybe(BodyText,EventHandler)
{
var Buttons='';
Buttons = '<a href=javascript:CloseForm("Yes");>Yes</a> ';
Buttons += '<a href=javascript:CloseForm("No");>No</a> ';
Buttons += '<a href=javascript:CloseForm("Maybe");>Maybe</a> ';
ModalDialogShow("Dialog",BodyText,Buttons,EventHandler);
}
function YesNoCancelReturnMethod()
{
document.getElementById('modalreturn1').value = ModalDialog.value;
ModalDialogRemoveWatch();
}
function YesNoMaybeReturnMethod()
{
document.getElementById('modalreturn2').value = ModalDialog.value;
ModalDialogRemoveWatch();
}
</script>
<BODY >
<table border=1 cellpadding=2 cellspacing=2 align=center width="60%">
<tr><td align=left></td></tr>
<tr><td align=left></td></tr>
<tr><td align=left></td></tr>
<tr>
<td align=left><a href="javascript:YesNoCancel('Yes, no, or cancel me','YesNoCancelReturnMethod()');">Show Modal #1</a>
1. <input type=text id=modalreturn1 name=modalreturn1 value=''></td>
