jQuery Validate (Date Range)
提问by Shane
Im using the jQuery validate plugin and was wondering if there was a way to validate if the date entered into a field was a date like yyyy-mm-dd AND the the date falls between Nov 29 2010 - Dec 15 2010
我正在使用 jQuery 验证插件，想知道是否有办法验证输入到字段中的日期是否是 yyyy-mm-dd 之类的日期，并且该日期介于 2010 年 11 月 29 日至 2010 年 12 月 15 日之间
Im pretty new to jQuery so if there is an answer please dumb up the answer as much as possible so i can get through it. Thanks a lot for any/all suggestions
我对 jQuery 还很陌生，所以如果有答案，请尽可能地把答案弄糊涂，这样我就可以通过它。非常感谢任何/所有建议

If you want a reusable function, you might extend Emily and lonesomeday's answers to allow an argument to be provided:
如果你想要一个可重用的函数，你可以扩展 Emily 和 lonesomeday 的答案以允许提供一个参数：
$.validator.addMethod('daterange', function(value, element, arg) {
// Same as above
var startDate = Date.parse(arg[0]),
endDate = Date.parse(arg[1]),
enteredDate = Date.parse(value);
// Same as below
}, $.validator.format("Please specify a date between {0} and {1}."))
See the sourceof the jQuery validation rangemethod for an example.

I've never used the validation plugin, but a look through the API suggests that something like this might work:
我从来没有使用过验证插件，但通过 API 看一下，这样的事情可能会奏效：
$.validator.addMethod('daterange', function(value, element) {
if (this.optional(element)) {
return true;
}
var startDate = Date.parse('2010-11-29'),
endDate = Date.parse('2010-12-15'),
enteredDate = Date.parse(value);
if (isNan(enteredDate)) {
return false;
}
return ((startDate <= enteredDate) && (enteredDate <= endDate));
});
You would then, I think, need to add the daterangeclass the the appropriate element.
然后，我认为，您需要为daterange类添加适当的元素。

lonesomeday's answer is pretty close, with a few tweaks. I would end the code as follows:
lonesomeday 的答案非常接近，有一些调整。我会按如下方式结束代码：
if(isNaN(enteredDate)) return false;
return ((startDate <= enteredDate) && (enteredDate <= endDate));
}, "Please specify a date between 2010-11-29 and 2010-12-15");
This fixes the isNaN function, and also provides an error message to your users so they know what you're looking for.
这修复了 isNaN 函数，并且还向您的用户提供了一条错误消息，以便他们知道您在寻找什么。

Made a couple small corrections in Connor's code.
对康纳的代码做了一些小的更正。
The resulting working code is:
生成的工作代码是：
$.validator.addMethod('daterange', function(value, element, arg) {
if (this.optional(element) && !value) {
return true;
}
var startDate = Date.parse(arg[0]),
endDate = Date.parse(arg[1]),
enteredDate = Date.parse(value);
if (isNaN(enteredDate)) {
return false;
}
return ( (isNaN(startDate) || (startDate <= enteredDate)) &&
(isNaN(endDate) || (enteredDate <= endDate)));
}, $.validator.format("Please specify a date between {0} and {1}."));
Then use it like this:
然后像这样使用它：
$("#some_date_input").rules("add",{daterange:['01/31/2001','01/31/2020']});

Do not forget, that Date.parse cannot work properly with different locales, it only parses properly specific date format.
不要忘记， Date.parse 不能在不同的语言环境下正常工作，它只能正确解析特定的日期格式。
If you use various date formats (culture-specific) - it's better to stick to jquery datepicker date handling.
如果您使用各种日期格式（特定于文化） - 最好坚持使用 jquery datepicker 日期处理。
So, supposing you've loaded correct culture-specific jquery datepicker object (for instance, jquery.ui.datepicker-nb-NO.js, where date format is DD.MM.yyyy and is not parsed by Date.parse) and initialized it, proper approach is:
因此，假设您已加载正确的特定于文化的 jquery datepicker 对象（例如，jquery.ui.datepicker-nb-NO.js，其中日期格式为 DD.MM.yyyy 且未由 Date.parse 解析）并初始化它，正确的做法是：
$.validator.addMethod('dateRange', function (value, element, parameterValue) {
if (this.optional(element) && !value) {
return true;
}
var dateFormat = $(element).datepicker('option', 'dateFormat');
try {
var startDate = $.datepicker.parseDate(dateFormat, parameterValue[0]).getTime();
var endDate = $.datepicker.parseDate(dateFormat, parameterValue[1]).getTime();
var enteredDate = $.datepicker.parseDate(dateFormat, value).getTime();
return (startDate <= enteredDate) && (enteredDate <= endDate);
} catch (error) {
return true;
}
});
I've put parseDate stuff inside try block, because there's no normal way to figure out if the date has been parsed properly.
我已经把 parseDate 的东西放在 try 块中，因为没有正常的方法来确定日期是否被正确解析。
