asp.net中无限制弹出模态窗口

特点：

1.可以在模态窗口上再弹出模态窗口,不限制次数

2.弹出窗口的支持拖放，及调整大小

3.弹出窗口关闭后可以动态控制是否刷新父窗口

总共需要3个页面来做演示

1.页面ModalDemo.aspx

前台代码：

<headrunat="server">

function OpenDialogWithReturn(url,width,height,formID,action)

var retValue = window.showModalDialog( url ,null,"dialogWidth:" \+ width + "px;dialogHeight:" \+ height + "px;help:no;unadorned:yes;resizable:yes;status:no;scrollbars:yes");

if (retValue != null && retValue != undefined && retValue == "SubmitForm")

if(action != null&& action != undefined && action.Length > 0)

formID.Action=action;

formID.submit();

</script>

</head>

<body>

<div>

<a href="\#" onclick="OpenDialogWithReturn('ModalPage1.aspx',520,410,form1,'ModalDemo.aspx');">通过页面脚本来弹出模态窗口</a><br/>

<br />

<br /><asp:Button ID="btnDetail" runat="server"

onclick="btnDetail\_Click" Text="通过动态注册弹出窗口"/>

&nbsp;<br/>

<div>

<%=DateTime.Now %>

</div>

</form>

</body>

后台代码：

protected void btnDetail\_Click(object sender, EventArgs e)

this.ClientScript.RegisterStartupScript(this.GetType(), "", "OpenDialogWithReturn('ModalPage1.aspx',520,410,form1,'ModalDemo.aspx');", true);

2．第二个页面ModalPage1.aspx

前台代码：

<headrunat="server">

<title>第一个模态窗口</title>

function OpenDialogWithReturn(url,width,height,formID,action)

var retValue = window.showModalDialog( url ,null,"dialogWidth:" \+ width + "px;dialogHeight:" \+ height + "px;help:no;unadorned:yes;resizable:yes;status:no;scrollbars:yes");

if (retValue != null && retValue != undefined && retValue == "SubmitForm")

if(action != null&& action != undefined && action.Length > 0)

formID.Action=action;

formID.submit();

</script>

</head>

<bodyonunload="window.returnValue='SubmitForm';">

<div>

通过页面脚本来弹出模态窗口</a>

<br />

<asp:Button ID="Button1" runat="server" Text="通过动态注册脚本来弹出模态窗口"

OnClick="Button1\_Click" />
