我尝试了很多组合,但还没能让它发挥作用.验证消息显示是否选中了复选框.

这是一些代码！

这是我用来验证下拉列表的自定义方法. (这适用于简单的DDL验证)

$.validator.addMethod(
    "selectNone",function(value,element) {
        return this.optional(element) || element.value != "Please Select...";
    },"Please select an option."
);

要根据复选框进行验证,我已在表单中添加了规则

$(document).ready(function() {
        var validator = $("#BuildingsCoverForm").validate({
            rules: {
                NCBYears: {
                    selectNone: function(element) {
                        return $("*[name='PrevIoUsInsurance']")[0].checked;
                    }
                }

            },messages: {
                NCBYears: {
                    selectNone: "This field is required"
                }
            }
        });
    });

这是控件.

<p>
        <label for="PrevIoUsInsurance" class="halfstretch">Do you have any prevIoUs insurance?</label>
        <%= Html.YesNoControl("PrevIoUsInsurance",Model.PrevIoUsInsurance)%>
    </p>
    <p>
        <label for="NCBYears" class="halfstretch">Building No Claim Bonus</label>
        <%= Html.DropDownList("NCBYears",ViewData["NCBYears"] as SelectList)%>
    </p>

任何想法将非常感谢.

非常感谢

解决方法

rules: {
  NCBYears: {
    required: function(element) {
      return $("input:radio[name='PrevIoUsInsurance']:checked").val() == 'yes';
    }
  }                
}
