我在我的 asp.net mvc 页面上使用 jquery daterange 验证器http://docs.jquery.com/Plugins/Validation/multiplefields。我的 html 看起来像这样:

 <tr>
            <td align="left" valign="top">
                <label>
                    <input name="fromDate" type="text" class="flat requiredDateRange jq_watermark" id="fromDate"
                        style="width: 190px" title="Creation From Date" readonly="readonly" />
                </label>
            </td>
        </tr>
        <tr>
            <td align="left" valign="top">
                <label>
                    <input name="toDate" type="text" class="flat requiredDateRange jq_watermark" id="toDate"
                        style="width: 190px" title="Creation To Date" readonly="readonly" />
                </label>
            </td>
        </tr>
        <tr>
            <td colspan="3" align="left" valign="top">
                <label id="error" class="error" style="display: block;">
                </label>
            </td>
        </tr>

在页面顶部,我正在使用这个:

$(document).ready(function(){
        $("#fromDate").datepicker({ dateFormat: 'dd MM yy', changeYear: true, changeMonth: true });
        $("#toDate").datepicker({ dateFormat: 'dd MM yy', changeYear: true, changeMonth: true });
});

jQuery(function () {

    jQuery("#frmSearch").validate({
        groups: {
            datesnotnull: "fromDate toDate",
            dateRange: "fromDate toDate"
        },
        errorPlacement: function (error) {
            jQuery("#frmSearch").find("#error").append('error');
           jQuery("#frmSearch").find("#error").show();

        }
    });

});

我的 daterangevalidator 文件如下所示:

// a custom method for validating the date range
$.validator.addMethod("datesnotnull", function () {  
    return (($("#fromDate").val().length != 0) && ($("#toDate").val().length != 0)) || (($("#fromDate").val().length == 0) && ($("#toDate").val().length == 0));
}, "Please specify the date range, from and to date.");

// a custom method for validating the date range
$.validator.addMethod("dateRange", function () {


    return ((($("#fromDate").val().length==0) && ($("#toDate").val().length==0)) || (new Date($("#fromDate").val()) < new Date($("#toDate").val())));
}, "Please specify a correct date range, the from date must be before the to date.");


// a new class rule to group all three methods
$.validator.addClassRules({
    requiredDateRange: { required: false, date: true, datesnotnull : true , dateRange: true  }    
});

// overwrite default messages
$.extend($.validator.messages, {    
    date: "Please specify valid dates"
});

但是当 todate 小于数据时,我只收到“Creation To Date”消息。我想显示消息“请指定正确的日期范围,起始日期必须早于截止日期”,这是红色的默认消息

您应该在 中使用以下选项validate()

ignoreTitle: true

new Date($("#fromDate").val()) 返回一个字符串。您应该比较毫秒值: new Date($("#fromDate").val()).getTime()
