c# gridview checkbox實現(xiàn)單選

關(guān)于gridview添加checkbox后，如何使用js添加單選事件，其實代碼不是很難，不過當(dāng)初也查了會資料，僅供記錄，高手繞道哈。。aspx中格式如下：

<div>
    <table>
        <td><asp:GridView ID="HumIdNmGridView">
            <Columns>
               <asp:TemplateField> 
                     <HeaderTemplate>
                         <asp:Image ID="oImg" runat="server" ImageUrl="../../p_w_picpaths/icon_sure.gif">
                         </asp:Image> //圖標(biāo)可以忽略
                       </HeaderTemplate>
                         <ItemTemplate>
                             <asp:CheckBox ID="chkSelected" runat="server" 
                             onclick="SingleCheck('HumIdNmGridView',this)"></asp:CheckBox>
                         </ItemTemplate>
            </td>
    </table>
</div>

下面是javascript：

var ClickCount = 0; //判斷同一checkbox連續(xù)點(diǎn)擊次數(shù)
        var PreCheckboxId = ""; //記錄點(diǎn)擊checkbox的ID
        //gridviewId 為傳入的gridview的Id
        function SingleCheck(DivGridView, SelectCheckBox) {
            //console.info(DivGridView);
            //console.info(SelectCheckBox);
            //判斷是否連續(xù)點(diǎn)擊同一個checkbox
            if (PreCheckboxId == SelectCheckBox) {
                ClickCount += 1;
            } else {
                PreCheckboxId = SelectCheckBox.id;
                ClickCount = 0;
            }
            //找到包含checkbox的divId
            var GridViewList = document.getElementById(DivGridView);
            //獲取divId中的多有input
            var objs = GridViewList.getElementsByTagName("input");
            for (var i = 0; i < objs.length; i++) {
                if (objs[i].type.toLowerCase() == "checkbox") {
                    objs[i].checked = false;
                }

                var SelectCheckBoxId = SelectCheckBox.id;
                //如果點(diǎn)擊的checkbox次數(shù)為奇數(shù)則checkbox為選中，反之不選中
                if (ClickCount % 2 != 1) {
                    document.getElementById(SelectCheckBoxId).checked = true;
                } else {
                    document.getElementById(SelectCheckBoxId).checked = false;
                }
            }
        }
