GridView的全选与反选，不选的问题

chenzhixin 2006-09-30 10:06:36

我的页面中用到GridView想实现全选等功能，可是我的怎么不行，老是找不到JS函数

文件 : manage/JScript.js

function selectAll()
{
var chk=document.getElementsByTagName['INPUT'];
for(int i=0;i<chk.length;i++)
{
if(chk[i].id!='chkBoxAll' && chk[i].id!='chkBoxNull'&&chk[i].id!='chkBoxRerverse')
if( chk[i].type='checkbox' )chk[i].checked=true;
}

}.....

文件: manage/admin_news.aspx
<GridView>

<Columns>

<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkBoxSelect" runat="server" />
</ItemTemplate>
</asp:TemplateField>
....</GridView>

<span id="SelectAll" runat="server" style="left: -13px; position: relative;
top: 10px" >Select All</span>
<span id="SelectRerverse" runat="server" style="left: -10px; position: relative;
top: 10px;">Rerverse</span>
<span id="SelectNull" runat="server" style="position: relative;
top: 10px">Select Null</span>

文件: manage/admin_news.aspx.cs

if (!IsPostBack) {

this.linkBtnAll_Click(null, null);
this.SelectAll.Attributes.Add("onclick","selectAll");
this.SelectNull.Attributes.Add("onclick","selectNull");
this.SelectRerverse.Attributes.Add("onclick","selectRerverse");
}

我这里的页面都用母版页来做的，其中母版页中

<head runat="server">
<link href="style.css" rel="Stylesheet" type="text/css" />
<script language=javascript type=text/javascript src=JScript.js ></script>
</head>

为什么还是找不到方法

<asp:Button ID="SelAll" runat="server" OnClick="SelALL_Click" Text="全部选中" />
protected void SelALL_Click( object sender, EventArgs e )
{
System.Web.UI.WebControls.CheckBox SelRecord;
if ( SelAll.Text == "全部选中" )
{
foreach ( DataGridItem item in MessageList.Items )
{

SelRecord = (CheckBox) item.FindControl( "SelRecord" );
SelRecord.Checked = true;
}
SelAll.Text = "全部不选";
}
else
{
foreach ( DataGridItem item in MessageList.Items )
{

SelRecord = (CheckBox) item.FindControl( "SelRecord" );
SelRecord.Checked = false;
}
SelAll.Text = "全部选中";
}
}

function SelectAll(tempControl)
{
//将除头模板中的其它所有的CheckBox取反

var theBox=tempControl;
xState=theBox.checked;

elem=theBox.form.elements;
for(i=0;i<elem.length;i++)
if(elem[i].type=="checkbox" && elem[i].id!=theBox.id)
{
if(elem[i].checked!=xState)
elem[i].click();
}
}

<HeaderTemplate>
<asp:CheckBox ID="CheckBox3" runat="server" Text="全选" onclick="javascript:SelectAll(this);"/>
</HeaderTemplate>
