点击子窗体给父窗体上的对象赋值

1. 父窗体:

<asp:TextBox ID="txtTitle" runat="server"></asp:TextBox>

<asp:DropDownList ID="ddlProgramCategory" runat="server">

<asp:ListItem Value="0">--类型--</asp:ListItem>

<asp:ListItem Value="1">台宣</asp:ListItem>

<asp:ListItem Value="2">广告</asp:ListItem>

<asp:ListItem Value="3">音乐</asp:ListItem>

</asp:DropDownList>

function $(s){return document.getElementById(s);}

function isNull(_sVal){return (_sVal == "" || _sVal == null || _sVal == "undefined");}

//获取地址栏参数

function GetUrl(name)

{

var URLParams = new Array();

var aParams = window.location.search.substr(1).split('&');

for (i=0; i < aParams.length; i++)

{

var aParam = aParams[i].split('=');

URLParams[aParam[0]] = aParam[1];

}

return URLParams[name];

}

function GetAddUrl()

{

var ddlProgramCategory = $('<%=ddlProgramCategory.ClientID %>');

var TitleID = $('<%=txtTitle.ClientID %>');//获取客户端对象

var DetailID = $('<%=DetailID.ClientID %>');

var ID = GetUrl("UnitID");

var categoryID = ddlProgramCategory.options[ddlProgramCategory.selectedIndex].value;

var url="";

switch (categoryID)//根据下拉框决定链接地址

{

case "1": url = "Ad1.aspx?UnitID=" + ID; break;

case "2": url = "Ad2.aspx?UnitID=" + ID; break;

case "3": url = "MusicCategory.aspx?UnitID=" + ID; break;

}

//将需要子窗体进行填充的对象的 ClientID 传到子窗体去

url += "&DetailID=" + DetailID.id + "&TitleID=" + TitleID.id ;

if(categoryID!="0") winOpen(url);

}

//弹出打开新页面-------------------------------------------

function winOpen(url)

{

var sFeatures='height=500, width=600, top=80, left=300,toolbar=0, menubar=0, scrollbars=1, resizable=1, location=1, status=1';

url = encodeURI(url);

window.open(url,"RM_ProgramDetail",sFeatures);

}

</script>

2.子窗体(注意GridView第一列input的onclick事件，当选择checkBox时将实时给父窗体赋值)

    <asp:GridView ID="GridView1" SkinID="gvClass2" runat="server" DataKeyNames="ID" OnRowDataBound="GridView1_RowDataBound"
        AutoGenerateColumns="False" Width="100%" AllowSorting="true" OnSorting="GridView1_Sorting"
        OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowEditing="GridView1_RowEditing"
        OnRowUpdating="GridView1_RowUpdating" OnRowDeleting="GridView1_RowDeleting">
        <Columns>
            <asp:TemplateField>
                <ItemTemplate>
                    <input id="check" runat="server" type="checkbox" value='<%# Eval("ID") %>' title='<%# Eval("Title")%>'
                        class='<%# FormatTime(Eval("Length")) %>' onclick="DoClick(this);" />
                </ItemTemplate>
                <HeaderTemplate>
                    <input id="checkAll" title="全选" onclick="javascript:CheckAll(this);" runat="server"
                        type="checkbox" />
                </HeaderTemplate>
                <ItemStyle Width="5%" />
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

<script language="javascript">
function $(s){return document.getElementById(s);}
function isNull(_sVal){return (_sVal == "" || _sVal == null || _sVal == "undefined");}
//获取地址栏参数
function GetUrl(name)
{
    var URLParams = new Array();
    var aParams = document.location.search.substr(1).split('&');
    for (i=0; i < aParams.length; i++)
    {
        var aParam = aParams[i].split('=');
        URLParams[aParam[0]] = aParam[1];
    }
    //取得传过来的name参数
    return URLParams[name];
}
//---------------------------------------------------------
function GetParentObj(strID)//获取父页面客户端对象
{
    return window.opener.document.getElementById(strID);
}

function DoClick(obj)
{
    var UnitID = GetUrl("UnitID");//获取地址栏中传来的父窗体对象的ClientID
    var TitleID = GetUrl("TitleID");
    var DetailID = GetUrl("DetailID");

    if(!isNull(DetailID) && !isNull(TitleID))
    {
        var Obj_DetailID = GetParentObj(DetailID);//获取父页面客户端对象
        var Obj_TitleID = GetParentObj(TitleID);
        if(obj.checked)
        {
            Obj_TitleID.value = obj.title;//给父窗体对象赋值
            Obj_DetailID.value = obj.value;
        }
        else
        {
            Obj_TitleID.value = "";
            Obj_DetailID.value = "";
        }
    }
}
</script>
