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.
For ‘selections’ like drop down and radio group, use an appropriate validation like ‘dontselect’ or ‘selone_radio’.
Validation attributes allow you to specify rules for a form input, such as whether a value must be filled in; the minimum and maximum length of the data; whether the data needs to be a number, an email address, or something else; and a pattern that the data must match.
If the entered data follows all of the specified rules, it is considered valid; if not, it is considered invalid.
The Java Script class presented here makes the form validations many times easier.
The script has a catalog of almost all the common validation types built-in.
The idea is to create a set of “validation descriptors” associated with each element in a form.
The “validation descriptor” is nothing but a string specifying the type of validation to be performed.
