如何在DataTables

我有一个加载了AJAX调用的表,并使用DataTables扩展为jQuery呈现。这是我的代码:

 $("#tblSelectedUserRoles").dataTable({
        bProcessing: true,
        sAjaxSource: '@Url.Action("GetAllRolesForUser")?' + "userId=" + $("#txtSelectedUserId").val(),
        bJQueryUI: true,
        sProcessing: "<img src='~/Images/spinner.gif' />",
        dom: 'T<"clear">rtip',
        bAutoWidth: false,
        "aoColumns": [
            { "sWidth": "1%", sClass: "smallFonts" },
            { "sWidth": "20%", sClass: "smallFonts" },
            { "sWidth": "20%", sClass: "smallFonts" },
            {
                "sWidth": "20%", sClass: "smallFonts", "sName": "UserRoleId", "mRender": function (data, type, row) {
                    return "<input type='checkbox' onchange=defaultrole('" + row[0] + "'); >";
                }},
            { "sWidth": "20%", sClass: "smallFonts" },
            {
                "sName": "UserRoleId", "sWidth": "20%", sClass: "smallFonts", "mRender": function (data, type, row) {
                    return "<button class='gridButton' onclick=deleterole('" + row[0] + "');>Delete Role</button>";
                }}
        ]
    });

我正在尝试在表格中添加一个复选框。复选框显示,当我点击其中任何一个时,我使用正确的user_role_id调用该函数没有问题。我的问题是数据来自控制器中的数据:

 [HttpGet]
    public ActionResult GetAllRolesForUser(string userId)
    {
        List<UserRoleModel> userroles = DataRepository.GetSelectedUserRoles(userId);
        return Json(new
        {
            aaData = userroles.Select(x => new String[] {
                x.UserRoleId,
                x.Role,
                x.RoleDesc,
                x.Default.ToString(),
                x.UarApproved.ToString()})
        }, JsonRequestBehavior.AllowGet);
    }

默认值和已批准值是布尔值,我必须将它们转换为字符串,然后在aaData中传递。在任何情况下,至少应该有一个复选框都没有设置。你怎么做到这一点?

您需要实际设置checked状态。如果应该定义已检查状态的值为UarApproved且该值是字符串化布尔值,请始终'true''false',请执行以下操作:

{
    sWidth: "20%",
    sClass: "smallFonts",
    sName: "UserRoleId",
    mRender: function(data, type, row) {
      return '<input type="checkbox" checked="'+row[4]+'" onchange=defaultrole('+row[0]+');/>';
    }
},
