JavaScript can do the validation checks easily. All you have to do is provide the values you want to validate.

Performs a check on all internal components (Leng Heng )
Although this password script would get you hacked in the blink of an eye, you could use <html> <head> <script type="text/javascript"> function PassCheck() { var pass=12345 var check=prompt("Enter Pass",""); if (pass==check) { document.write("Correct!") } else { document.write("Incorrect!") } } </script> </head> <body> <button type="button" onclick="PassCheck()">Enter Password</button> </body> </html>
Use the length property of string in javascript.
function uncheck () { form1.chkbx1.checked=false; } form1 is the name/id of the form chkbx1 is the name/id of the checkbox
Digit Check
Validation rules limit what can go into a field. You might want to only allow values that are over 500 in a field, so the validation would be: >500 You might want dates that are before the 1st of January 2010, so that would be like this: <#01/01/2010#
JavaScript is written within an HTML page (or in an external .js file but technically it's still part of the page) and adds special effects to that page. W3Schools has some really good tutorials. You can find the link in the related links. You can write JavaScript in Notepad! However most people prefer an IDE. I like Komodo Edit, personally. You can find a link for Komodo in the Related Links.
as far as i know they are: <script type="text/javascript"> all my lovely javascript code!!! </script>
Field validation ensures that a program or form is using clean incorrect data. A set of validation rules are used to check data that is entered into a system before it is processed.
JavaScript can be useful for turning HTML into something more dynamic and interesting to the user. Also, you can do things like check to see if fields have been filled before a submit function is clicked. Although sometimes JavaScript can be ugly and very un-professional, it still has its uses today.
Could it be check Digits?
