使用Jquery向一个空白网页动态创建一个iframe,及嵌入页面,和向嵌入页面传参
using Microsoft.VisualBasic;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;
using System.Collections.Specialized;
using Microsoft.JScript;
namespace MCS
{
public partial class MyDialog : System.Web.UI.Page
{
protected string strParam = null;
private void Page_Load(System.Object sender, System.EventArgs e)
{
}
public string GetParam()
{
strParam = string.Empty;
int loop1 = 0;
int loop2 = 0;
string[] arr1 = null;
string[] arr2 = null;
NameValueCollection coll = null;
//Load Form variables into NameValueCollection variable.
coll = Request.QueryString;
//Get Names of all keys into a string array.
arr1 = coll.AllKeys;
for (loop1 = 0; loop1 <= arr1.GetUpperBound(0); loop1++)
{
strParam = strParam + arr1[loop1] + "=";
// Get all values under this key.
arr2 = coll.GetValues(loop1);
for (loop2 = 0; loop2 <= arr2.GetUpperBound(0); loop2++)
{
if (Information.IsDate(arr2[loop2]))
arr2[loop2] = DateTime.Parse(arr2[loop2]).ToString("MM/dd/yyyy hh:mm:ss tt");
strParam = strParam + arr2[loop2] + "&";
}
}
if (strParam.Length > 0 && strParam.Contains("&"))
strParam = strParam.TrimEnd('&');
return strParam;
}
public string GetPage()
{
return Request.QueryString["Page"];
}
}
}
以上GetPage方法得到iframe里嵌入的页面,GetParam方法则是得到要传递的参数
下面是前台Jquery页面
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="MyDialog.aspx.cs" Inherits="MCS.MyDialog" %>
<!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>Dialog</title>
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript" language="javascript">
$(document).ready(function () {
var if_w = $("body").width();
var if_h = $(window).height();
$("<iframe width='" + if_w + "' height='" + if_h + "' id='Frame1'></iframe>").prependTo('body');
$("#Frame1").attr("src", "<%= GetPage() %>" + "?" + unescape("<%= GetParam() %>"));
});
</script>
</head>
<body>
</body>
</html>
至于为什么要放在iframe里面,而不直接使用load方法,是为了防止跳转时弹出一个新页面,而不是在本页面中跳转
