請參考如下代碼：
在頁面A<head></head>中加入代碼：
<script language="javascript">
function ProScrap()
{//關閉頁面B ：result將得到window.returnValue=AProScrap的值
var result=window.showModalDialog("頁面B.aspx","","directories:no;status:no;toolbar:no;scroll:no;help:no;dialogWidth:280px;dialogheight:200px");
}頁面B中加入：
<script language="javascript">
function ISfileValue()
{
var AProScrap=document.getElementById('IPProScrap').value;
if(AProScrap!="" && AProScrap!=undefined)
{
var value=AProScrap.substr(AProScrap.lastIndexOf("\\")+1);
AProScrap="ChangWu\\ProScrap\\" + value;
window.returnValue=AProScrap;
}
}
</script>
在頁面A<head></head>中加入代碼：
<script language="javascript">
function ProScrap()
{//關閉頁面B ：result將得到window.returnValue=AProScrap的值
var result=window.showModalDialog("頁面B.aspx","","directories:no;status:no;toolbar:no;scroll:no;help:no;dialogWidth:280px;dialogheight:200px");
}頁面B中加入：
<script language="javascript">
function ISfileValue()
{
var AProScrap=document.getElementById('IPProScrap').value;
if(AProScrap!="" && AProScrap!=undefined)
{
var value=AProScrap.substr(AProScrap.lastIndexOf("\\")+1);
AProScrap="ChangWu\\ProScrap\\" + value;
window.returnValue=AProScrap;
}
}
</script>
function doResult(str1,str2){
document.getElementById("txtkeywords1").value = str1;
document.getElementById("txtkeywords2").value = str2;
}
2 加弹出窗口上加上js
<script language="javascript">
function onselect(val)
{
top.opener.doResult(val);
top.window.close();
}
</script> 3 在列表的绑定事件上加上这个
private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
((LinkButton)e.Item.FindControl("btnSelect")).Attributes.Add("onclick", "javascript:onselect("+e.Item.Cells[1].Text.Trim()+","+e.Item.Cells[1].Text.Trim()+");"); } 上面是参考,要作适当修改
}
在WebForm5.aspx页面的.cs 中
protected void Page_Load(object sender, EventArgs e)
{
Response.Write("<script>window.open('WebForm6.aspx')</script>");
}
在WebForm6.aspx页面中有一个CheckBoxList和一个Button1
在WebForm5.aspx页面的.cs 中
protected 6oid Button1_Click(object sender, EventArgs e)
{
string checkBoxVlaues = string.Empty;
for (int i = 0; i < CheckBoxList1.Items.Count; i++)
{
if (this.CheckBoxList1.Items[i].Selected)
{
checkBoxVlaues += CheckBoxList1.Items[i].Value;
}
}
Response.Write("<script>window.opener.document.getElementById('TextBox1').value='"+checkBoxVlaues+"';window.close(); </script>");
}
这样的话就可以在WebForm5.aspx页面TextBox1上显示你选择的值了。
在弹出页的页面关闭的时候，加个返回值
var top;
var left;
top=(window.screen.availHeight-407)/2;
left=(window.screen.availWidth-583)/2;
window.open("newpaper/picman.aspx?fileid=<%=fileid%>&pathid=<%=pathid%>&objectName=<%=objectName%>","相关图片",
"height=407,width=583,left="+left+",top="+top+",status=no,toolbar=no,menubar=no,location=no,help=no,scrollbars=yes");
}
父窗体的JS代码：
function viewgroup(){
//var roleslist = window.showModalDialog("ShowDialog.aspx","","dialogHeight:750px;dialogWidth:650px;center:yes;");
var url="ShowDialog2.aspx"; //转向网页的地址;
var name=""; //网页名称，可为空;
var iWidth=650; //弹出窗口的宽度;
var iHeight=700; //弹出窗口的高度;
var iTop = (window.screen.availHeight-30-iHeight)/2; //获得窗口的垂直位置;
var iLeft = (window.screen.availWidth-10-iWidth)/2; //获得窗口的水平位置;
window.open(url,name,'height='+iHeight+',,innerHeight='+iHeight+',width='+iWidth+',innerWidth='+iWidth+',top='+iTop+',left='+iLeft+',toolbar=no,menubar=no,scrollbars=Yes,resizeable=no,location=no,status=no');
}
子窗体的代码：
function winreturn(){
//getCheckValue();
var boxes = document.getElementsByName("TypeId");
var groupTypeId = new Array();
var groupTypeName= new Array();
var j = 0;
var tempvalue;
for (var i = 0; i < boxes.length; i++)
{
if (boxes[i].checked)
{
tempvalue= boxes[i].value;
groupTypeName[j] = tempvalue.split("|")[1];
groupTypeId[j]= tempvalue.split("|")[0];
j++;
}
tempvalue = "";
}
window.opener.document.getElementById("ctl00_ContentPlaceHolder2_selectInfo_DropCity").value=groupTypeId.toString();
window.opener.document.getElementById("ctl00_ContentPlaceHolder2_selectInfo_DropCustomerName").value=groupTypeName.toString(); window.close();
}
