jQuery Datepicker:验证日期 [英] jquery datepicker: validate date

问题描述

我已经设置了一个jQuery类:

$(function() {
            $( ".datepickerIT" ).datepicker({
                showOtherMonths: true,
                selectOtherMonths: true,
                showAnim: "clip",
                dateFormat: "dd/mm/yy",
                minDate: "01/01/1925",
                maxDate: "31/12/2050",
                changeMonth: true,
                changeYear: true,
                yearRange: "1925:2050",
                regional: "it"                      
            });
        });

我想添加一个日期检查控件，如果用户输入的日期无效，该控件将发出警报

如何将这样的检查添加到".datepickerIT"类中?

onClose: function(dateText, inst) {
        try {
            $.datepicker.parseDate('dd/mm/yy', dateText);
        } catch (e) {
            alert(e);
        };

我必须在头部添加哪些插件?

不建议使用

解决方案

Date.parse，因为在不同的主机解析日期字符串的方式上仍然存在许多差异. [1] [2]

我会用瞬间进行日期验证.

moment(newDate, 'DD/MM/YYYY', true).isValid()

i have set a jquery class:

$(function() {
            $( ".datepickerIT" ).datepicker({
                showOtherMonths: true,
                selectOtherMonths: true,
                showAnim: "clip",
                dateFormat: "dd/mm/yy",
                minDate: "01/01/1925",
                maxDate: "31/12/2050",
                changeMonth: true,
                changeYear: true,
                yearRange: "1925:2050",
                regional: "it"                      
            });
        });

I want to add a date check control that alert if user input not is a valid date

How can add to the class ".datepickerIT" a check like this?

onClose: function(dateText, inst) {
        try {
            $.datepicker.parseDate('dd/mm/yy', dateText);
        } catch (e) {
            alert(e);
        };

And what plugin i must include into head section?

解决方案

Date.parse is not recommend to use as there are still many differences in how different hosts parse date strings. [1][2]

I would use moment for date validation.

moment(newDate, 'DD/MM/YYYY', true).isValid()
