validating a date in javascript-43

In Java Script to check for different month lengths, particularly for February in leap years, you need quite a bit of extra code.I'm not going to show that here, but you can find a link to get started under References below. //-------------------------------------------------------------------------- function check Entered Dates(stdateval,endateval) //-------------------------------------------------------------------------- //This function validates the date for MM/DD/YYYY format.//-------------------------------------------------------------------------- function is Valid Date(date Str) //These functions go between the tags.These functions can even be included from an external javascript file so that the browser can cache them, and so the programmer isn't always copying and pasting.

In this case, we've created a stand-alone functions which will validate a date field: In each case the value passed to the function is the form field rather than the field value.We have also provided the javascript date validation for the dd/mm/yyyy format.If the valid date character is changed please make sure you replace it in the HTML and Javascript code too.Now the date string is seperated into the month, day and year integers.They are each validated seperately and combined together.Each of these values is then tested against an allowed range (days: 1 - 31; months: 1 - 12; years: 1902 - 2019; and so on).
