在layer弹出层中通过ajax返回html拼接字符串填充数据

1，在给一个layer弹出层做checkbox自动选中时，ViewBag传递的时object类型，用不了lambda表达式，代码如下，

@foreach (var perm in ViewBag.allPerms)
{
       <input type="checkbox" id="permissionIds_@perm.Id" 
         name="PermissionIds" value="@perm.Id"   
 checked="@(ViewBag.RolePerms.Select(r=>r.Id).Contains(perm.Id))"/>
         <label for="permissionIds_@perm.Id">@perm.Name</label>
}

2，于是在弹出层就不写foreach循环遍历checkbox，直接在点击编辑事件时的弹出层中 ‘添加层弹出后的成功回调方法success’ ，在里面通过ajax填充数据

Control中Edit方法获取数据

//填充角色数据并显示
public ActionResult Edit(long roleId = 0)
 {
      if (roleId == 0)
      {
          return Json(new JsonData { State = 0, ErrorMsg = "角色不存在！" });
       }
       var role = RoleService.GetById(roleId);
       if (role==null)
       {
           return Json(new JsonData { State = 0, ErrorMsg = "角色Id不存在！" });
        }
        var allPerms = PermissionService.GetAll();
        var rolePerms = PermissionService.GetByRoleId(roleId);
        RoleEditGetModel model = new RoleEditGetModel();
        model.RolePerms = rolePerms;
        model.AllPerms = allPerms;
        return Json(new JsonData { State = 1, Data = model });
  }

View中Layer弹出层success方法

success: function (layero, index) {
                //填充数据
                $.ajax({
                    url: "/Role/Edit?roleId=" + id,
                    type: "post",
                    dataType: "json",
                    success: function (res) {
                        if (res.State == 1) {
                            var html = "";
                            var bool = false;
                            for (var i = 0; i < res.Data.AllPerms.length; i++) {
                                bool = false;
                                for (var j = 0; j < res.Data.RolePerms.length; j++) {
                                    if (res.Data.RolePerms[j].Id == res.Data.AllPerms[i].Id) {
                                        bool = true;
                                        break;
                                    }
                                }
                                html += ' <input ' + (bool ? "checked" : "") + ' type="checkbox" id="permissionIds_' + res.Data.AllPerms[i].Id + '" name="PermissionIds" value="' + res.Data.AllPerms[i].Id + '" /> 
                                   <label for="permissionIds_' + res.Data.AllPerms[i].Id + '">' + res.Data.AllPerms[i].Name + '</label>'
                            }
                            $("#formValue").html(html);
                        }
                    },
                    error: function () {
                        layer.alert('网络请求失败！', {
                            title: '提示框',
                            icon: 0,
                        });
                    }
                });
            },
