showModalDialog

 基本介绍:
showModalDialog() (IE 4+ 支持)
showModelessDialog() (IE 5+ 支持)
window.showModalDialog()方法用来创建一个显示HTML内容的模态对话框。
window.showModelessDialog()方法用来创建一个显示HTML内容的非模态对话框。

使用方法:
vReturnValue = window.showModalDialog(sURL [, vArguments] [,sFeatures])
vReturnValue = window.showModelessDialog(sURL [, vArguments] [,sFeatures])

参数说明:
sURL--
必选参数,类型:字符串。用来指定对话框要显示的文档的URL。
vArguments--
可选参数,类型:变体。用来向对话框传递参数。传递的参数类型不限,包括数组等。对话框通过window.dialogArguments来取得传递进来的参数。
sFeatures--
可选参数,类型:字符串。用来描述对话框的外观等信息,可以使用以下的一个或几个,用分号“;”隔开。
1.dialogHeight :对话框高度,不小于100px,IE4中dialogHeight 和 dialogWidth 默认的单位是em,而IE5中是px,为方便其见,在定义modal方式的对话框时,用px做单位。
2.dialogWidth: 对话框宽度。
3.dialogLeft: 离屏幕左的距离。
4.dialogTop: 离屏幕上的距离。
5.center: {yes | no | 1 | 0 }:窗口是否居中,默认yes,但仍可以指定高度和宽度。
6.help: {yes | no | 1 | 0 }:是否显示帮助按钮,默认yes。
7.resizable: {yes | no | 1 | 0 } [IE5+]:是否可被改变大小。默认no。
8.status: {yes | no | 1 | 0 } [IE5+]:是否显示状态栏。默认为yes[ Modeless]或no[Modal]。
9.scroll:{ yes | no | 1 | 0 | on | off }:指明对话框是否显示滚动条。默认为yes。
下面几个属性是用在HTA中的,在一般的网页中一般不使用。
10.dialogHide:{ yes | no | 1 | 0 | on | off }:在打印或者打印预览时对话框是否隐藏。默认为no。
11.edge:{ sunken | raised }:指明对话框的边框样式。默认为raised。
12.unadorned:{ yes | no | 1 | 0 | on | off }:默认为no。

参数传递:
1.要想对话框传递参数,是通过vArguments来进行传递的。类型不限制,对于字符串类型,最大为4096个字符。也可以传递对象,例如:
-------------------------------
parent.htm
<script>
var obj = new Object();
obj.name="51js";
window.showModalDialog("modal.htm",obj,"dialogWidth=200px;dialogHeight=100px");
</script>
modal.htm
<script>
var obj = window.dialogArguments
alert("您传递的参数为:" + obj.name)
</script>
-------------------------------
2.可以通过window.returnValue向打开对话框的窗口返回信息,当然也可以是对象。例如:
------------------------------
parent.htm
<script>
str =window.showModalDialog("modal.htm",,"dialogWidth=200px;dialogHeight=100px");
alert(str);
</script>
modal.htm
<script>
window.returnValue="http://www.51js.com";
</script>

例子:

   function AddActionPlan()
    {
        //debugger
        var ActionPlan = document.getElementById("txt_ActionPlan").value;
        var CompleteTime = document.getElementById("txt_Time").value;
