Validating registration forms using javascript

It is getting error in console please give me help.

It is a registration form with Java Script validation.

For example, you can have an input field that should not be empty, should be less than 25 chars and should be alpha-numeric. In some dynamically programmed pages, it may be required to change the validations in the form at run time.

In other words, in order to validate a field, you just associate a set of validation descriptors for each input field in the form. For such cases, a function is included which clears all validations in the validator object. Note that this validation if for fields like Textbox and multi-line text box.

And also after validating using javascript, display proper error message in text box where there is an error.

This validation descriptor is valid only for drop down lists.The “validation descriptor” is nothing but a string specifying the type of validation to be performed.Each field in the form can have zero one or more validations. More info & downloads where Do My Validation One() and Do My Validation Two() are custom functions for validation.So here is the Regular expression pattern:/^[A-Z][0-9] ?[0-9][A-Z]$/i The i at the end of the pattern is to indicate that this is a case insensitive match.

When there are many fields in the form, the Java Script validation becomes too complex.
