验证结束日期是在开始日期之后 [英] Validate end_date is after start_date

问题描述

我有一个带有两个日期字段的表格，start_date和end_date.我想创建一个规则，该规则end_date必须大于start_date，如果此条件返回false，则如下图所示显示验证错误.

I have a form with two date fields, start_date and end_date. I want to create a rule that end_date must be greater then start_date, and if this condition returns false then to show validation errors as in the picture below.

到目前为止，我已经尝试通过创建自定义规则来做到这一点:

So far I've tried to do so by creating a custom rule:

$.validator.addMethod("check_date", function(value, element) {
    var start_date = $("input[name='start_date']").val();
    var end_date = $("input[name='end_date']").val();
    return end_date(value) > start_date(value);
}, 'End date must be greater then start date.');

我不确定我如何精确设置规则和消息.

I'm not sure how exactly I set the rule and the message.

推荐答案

知道了.

   $.validator.addMethod("check_date", function(value, element) {
    var start_date = $("input[name='start_date']").val();
    var end_date = $("input[name='end_date']").val();
    return end_date > start_date;
}, 'End date must be greater then Start date.');
