c# - JQuery勾选项CheckBoxList

Question

我尝试在用户控件中使用 JQuery 客户端检查 CheckBoxList 中的特定项目？

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:AppCon %>"     
    SelectCommand="SELECT DesF, val, DesGrpId FROM dbo.tblDes WHERE (DesGrpId = @DesGrpId)">    
</asp:SqlDataSource>

<asp:CheckBoxList ID="CheckBoxList1" runat="server" DataTextField="DesF" DataValueField="val"
    DataSourceID="SqlDataSource1">

Answer 1

服务器端控制:

<asp:CheckBoxList ID="ChkList" runat="server">
    <asp:ListItem Text ="a" Value="1"></asp:ListItem>
    <asp:ListItem Text ="b" Value="2"></asp:ListItem>
    <asp:ListItem Text ="c" Value="3"></asp:ListItem>
</asp:CheckBoxList>

客户端代码:

<script type="text/javascript">
    $(function () {
        var str = "1,2";
        var list = $('#<%= ChkList.ClientID%> input');
        list.each(function (index) {
            item = $(this);
            if (str.indexOf(item.val()) != -1) {
                item.attr('checked', true);
            }
        });
    });
    </script>
