关于showModalDialog 的常见问题
在我们的实际开发中,经常会用到showModalDialog 模态窗体,对于其中的问题有时候真是让人头痛,在此我写一点自己在开发中遇到的问题以及解决办法。
一、刷新问题
第一种情况是:模态窗体的父窗体不刷新问题,就是在关闭模态窗口后,父窗体不刷新。
解决方法:在你的弹出模态窗体的JavaScript后面写上window.location.reload();
第二种情况是:有时候不想让父窗体刷新,也就是在关闭模态窗口后,让父窗体不刷新
解决方法:在你的弹出模态窗体的JavaScript后面写上return false;
二、关闭问题
关闭方法:使用JavaScript
window.opener=null;self.close();
三、传递对象
1 protected void btnOK_Click(object sender, EventArgs e)
2 {
3 System.Text.StringBuilder sb = new System.Text.StringBuilder();
4 sb.Append("<script language=\"javascript\">");
5 string strReturnText = string.Empty;
6 string strReturnValue = string.Empty;
7 if (Request.Form["rbtnSelect"] != null)
8 {
9 strReturnText = Request.Form["rbtnSelect"].ToString();
10 strReturnValue = Request.Form["rbtnSelect"].ToString();
11 // Response.Write(strReturnText);
12 }
13 if (rdo_NewLocation.Checked == true)
14 {
15 // strReturnText = Request.Form["rbtnSelect"].ToString();
16 // strReturnValue = Request.Form["rbtnSelect"].ToString();
17
18 sb.Append(" var ret = new Object();");
19 sb.Append(" ret.txt_BuildingName = '" + txt_BuildingName.Text + "'; ");
20 sb.Append(" ret.txt_Unit = '" + txt_Unit.Text + "'; ");
21 sb.Append(" ret.txt_Floor = '" + txt_Floor.Text + "'; ");
22 sb.Append(" ret.txt_StreetNo = '" + txt_StreetNo.Text + "'; ");
23 sb.Append(" ret.txt_Street = '" + txt_Street.Text + "'; ");
24 sb.Append(" ret.txt_District = '" + txt_District.Text + "'; ");
25 sb.Append(" ret.txt_City = '" + txt_City.Text + "'; ");
26 sb.Append(" ret.txt_Country = '" + txt_Country.Text + "'; ");
27
28 }
29
30 // sb.Append("window.returnValue='" + strReturnText + "|" + strReturnValue + "';");
31 sb.Append("window.returnValue=ret;");
32 sb.Append("window.close();");
33 sb.Append("</script>");
34 Response.Write(sb.ToString());
35 }
36 父页面接收
<script language="JavaScript" type="text/javascript">

var ret = window.showModalDialog("../Common/RelocationSelection.aspx",'','dialogWidth:630px; dialogHeight:300px;');
