This is the best time to check whether required fields have been filled or to perform checks that involve dependencies between multiple elements.

We perform this check with Java Script's // form // Common functions used with forms // // We use this as a hash to track those elements validated on a per element // basis that have formatting problems validate = new Object( ); // Takes a value, checks if it's an integer, and returns true or false function is Integer ( value ) // Takes a value and a range, checks if the value is in the range, and // returns true or false function in Range ( value, low, high ) // Checks values against formats such as '#####' or '###-##-####' function check Format( value, format ) // Takes a form and an array of element names; verifies that each has a value function require Values ( form, required Values ) // Takes a form and an array of element names; verifies that each has an // option selected (other than the first; assumes that the first option in // each select menu contains instructions) function require Selects ( form, required Select ) // Takes a form and an array of element names; verifies that each has a // value checked function require Radios ( form, required Radio ) // Verify there are no uncorrected formatting problems with elements // validated on a per element basis function check Problems ( ) // Verifies that the value of the provided element has ##### format function check Zip ( element ) // Verifies that the value of the provided element has ###-###-#### format function check Phone ( element ) // Verifies that the value of the provided element has ###-##-#### format function check SSN ( element ) // Verifies that the value of the provided element is an integer between 1 and 150 function check Age ( element ) takes a value as well as a string containing a format to check the value against.

Some may argue that it is poor design to write the same code twice, and they are right in that avoiding duplicate code is a good principle of designing maintainable code.
