Hi, I'm new to javascript, and I need to find a way to validate a Time field. When a user updates a record, the time comes in HH:MM:SS AM or HH:MM:SS PM. However, it does not matter what format they enter when updating the record. It can be military or HH:MM AM.

Is there a validation function out there that will allow me to check for all valid times? If not, the first mentioned format will do.

Any help would be appreciated.

If you want time and date then just use the Date constructor:

<input type="text" onchange="this.value=new Date(this.value).toDateString()">

But otherwise you will have to prepend the date:

<input type="text" onchange="this.value=new Date(new Date().toDateString() + this.value).toDateString()">

No date, just time. And by validate, I mean checking to see if it is a valid time before submitting the form. I.E, if a user has entered "11:65 PM", an alert message will say "What are you thinking? That's not a valid time."
