Repeater Checkbox 全选

Question

请问一下，我在Repeater的模版中使用了checkbox，我现在有一个总的checkbox，我选择总的checkbox，就可以全选Repeater里面的所有checkbox，我知道要用js，我的问题是js应该怎么写，然后怎么插入到网页中与总的checkbox关联起来呢？！

if (this.Button1.Text == "全选")
        {
            foreach (DataListItem dli in this.DataList1.Items)
            {
                CheckBox cb = (CheckBox)dli.FindControl("select");
                cb.Checked = true;
            }            this.Button1.Text = "全部取消";
        }
        else 
        {
            foreach (DataListItem dli in this.DataList1.Items)
            {
                CheckBox cb = (CheckBox)dli.FindControl("select");
                cb.Checked = false;
            }            this.Button1.Text = "全选";
        }这是DataList的  试试呗

给段代码自己看看就明白了...原理很简单 <script language="javascript" type="text/javascript">
        function checkAll(CheckAll) {
            var items = document.getElementsByTagName("input");
            for (i = 0; i < items.length; i++) {
                if (items[i].type == "checkbox") {
                    items[i].checked = CheckAll.checked;
                }
            }
        }

<script language="javascript" type="text/javascript">
    <!--
        function SelectAllCheckBox()
        {
            var form =document.forms[0];
            for(i=0;i<form.elements.length;i++)
            {
                if(form.elements[i].type=="checkbox")
                {
                    form.elements[i].checked=true;
                }
            }
        }
        function ReSelectCheckBox()
        {
            var form =document.forms[0];
            for(i=0;i<form.elements.length;i++)
            {
                if(form.elements[i].type=="checkbox")
                {
                    if(form.elements[i].checked)
                        form.elements[i].checked=false;
                    else
                        form.elements[i].checked=true;
                }
             }
        }
    //-->
    </script>
<input id="btnSelectAll" class="TextBox" onclick="SelectAllCheckBox()" type="button"
                value="全　　选" />
            <input id="btnReSelect" class="TextBox" onclick="ReSelectCheckBox()" type="button"
                value="反　　选" />
如果不喜欢用JS 后台遍历也可以。全选反选
