I have a jQuery form that has validation of a sort. It is a data entry screen with two 'recommend ranges', one is 36-84,
the other 50-300.
The business rules call for
the values to be either blank or greater than zero, but to prompt for confirmation if
the values are outside of
the range listed above.
I have seen some other threads that talk about setting
the class="cancel" on
the submit button. From what I can tell, this will simply disable
the validation. I need to prompt for a "do you want to continue, yes or no?" and if no stop
the submit, if yes, continue.
Below is an example from
the book Pro jQuery. By default
the top row needs to be between 10 and 20 to submit. How would you change it so that it prompts you and if you say Yes it submits, no prevents
the submit:
