jQuery Validator插件增加日期比较

$(document).ready(function() {

$("#< %= btnSubmit.ClientID %>").click(function() {

$("#aspnetForm").validate({

rules: {

ctl00$ContentPlaceHolder1$ucProjInfo1$ucDatePicker2$txtDatePicker: {

required: true,

date: true,

//日期比较验证方法

endDate: true

}

}

});

});

//自定义验证方法

jQuery.validator.addMethod("endDate",

function(value, element) {

var startDate = $('#start_date').val();

return new Date(Date.parse(startDate.replace("-", "/"))) < = new Date(Date.parse(value.replace("-", "/")));

},

"结束日期必须大于开始日期!");

});
