利用javascript打开模态对话框(示例代码)
1. 标准的方法
代码如下:
<script type="text/javascript"> function openWin(src, width, height, showScroll){ window.showModalDialog (src,"","location:No;status:No;help:No;dialogWidth:"+width+";dialogHeight:"+height+";scroll:"+showScroll+";"); } </script>
例:<span style="CURSOR: pointer" onclick="openWin
('//www.jb51.net', '500px', '400px', 'no')">点击</span>
2. 要注意的是,Firefox并不支持该功能,它支持的语法是
window.open
('openwin.html','newWin', 'modal=yes, width=200,height=200,resizable=no, scrollbars=no' );
3. 如何自动判断浏览器
代码如下:
<input type="button" value="打开对话框" onclick="showDialog('#')"/> <SCRIPT LANGUAGE="JavaScript"> <!-- function showDialog(url) { if( document.all ) //IE { feature="dialogWidth:300px;dialogHeight:200px;status:no;help:no"; window.showModalDialog(url,null,feature); } else { //modelessDialog可以将modal换成dialog=yes feature ="width=300,height=200,menubar=no,toolbar=no,location=no,"; feature+="scrollbars=no,status=no,modal=yes"; window.open(url,null,feature); } } //--> </SCRIPT>
4. 在IE中,模态对话框会隐藏地址栏,而在其他浏览器则不一定
【注意】在谷歌浏览器中,这个模态的效果也会失效。
5. 一般在弹出对话框的时候,我们都希望整个父页面的背景变为一个半透明的颜色,让用户看到后面是不可以访问的
而关闭对话框之后又希望还原
这是怎么做到的呢?
代码如下:
///显示某个订单的详细信息,通过一个模态对话框,而且屏幕会变颜色 function ShowOrderDetails(orderId) { var url = "details.aspx?orderID=" + orderId; // $("body").css("filter", "Alpha(Opacity=20)"); //filter:Alpha(Opacity=50) $("body").addClass("body1"); ShowDetailsDialog(url, "600px", "400px", "yes"); $("body").removeClass("body1"); }
另外,有一个样式表定义
.body1
{
background-color:#999999;
filter:Alpha(Opacity=40);
}
代码如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title></title> <style type="text/css"> .body1{ background-color:#999999; filter:Alpha(Opacity=40); } </style> <script src="jquery.js" type="text/javascript"></script> <script type="text/javascript"> function ShowDetailsDialog(src, width, height, showScroll) { window.showModalDialog(src, "", "location:No;status:No;help:NO;dialogWidth:" + width + ";dialogHeight:" + height + ";scroll" + showScroll + ";"); } function ShowOrderDetails(orderId) { var url = 'Details.aspx?orderID=' + orderId; $("body").addClass("body1"); ShowDetailsDialog(url, '500px', '400px', 'no'); $("body").removeClass("body1"); } </script> </head> <body> <form id="form1" runat="server"> <div> <span style="cursor:pointer" onclick="ShowOrderDetails(11)" >点击</span> </div> </form> </body> </html>
