javascript validation date is an important part of every web browser. This is because it allows the browser to validate your input before sending it to the server. This is one of the reasons why you see so many different date formats. Some of them are standardized, while others are just different ways to express the same idea. Since JavaScript is a server side language, it doesn’t have a standard.
Javascript validation date is the reason that you see the dashes between characters, like this one: 3/1/2012, instead of just “3”. The reason is that javascript validation date is a client side language, which means that the browser can only parse the date from the server to determine if it is a valid date.
Javascript validation date is a very specific thing that only the browser parses. So what makes it different from other date formats? The difference is that javascript validation date is all in the date string, which means that you can’t parse it with the javascript date parsing functions. If you try to, the browser will probably crash.
The good news? It’s easy to fix. I say that because if you wanted to do it yourself, you could use a tiny little function in javascript and just ignore the date format for the moment.
This is actually really handy because we use javascript date validators for dates that don’t have a date time component. We don’t want to throw errors when the date is invalid. We want to catch any errors and then tell the user what kind of error it is.
I have a big list of date/time validators from various places, and I can already tell they are all pretty much the same. But a small but important difference comes from the fact that those date/time validators use a “validator” function that accepts a date object, not a string. This function is called validateDate and it is documented here.
jQuery comes with a list of validators, not just jQuery. It’s also documented here.
Here is a function that we use in our validators:validateDate. It is pretty easy to get working with the date object.
If you have a date object that you want to validate, you can pass it in as the first parameter of the function. If you are using the jQuery Datepicker you can use the.datepicker( ‘picker’, { dateFormat:’mm/dd/yyyy’ }) function that goes in the options of the datepicker. You can also make your own functions using those.
I have to admit, I have struggled with date validation. I’m sure I have missed something that is worth mentioning here, but I haven’t had a lot of success with dates.
