Question

I am looking for the following functionality:

The user is required to fill in either one of two fields to be able to submit. (e.g. There is a phone number field and an email field and the user must fill in at least 1 to leaves some sort of contact details.)

How can do I possibly do this through jquery? Forgive me as I am relatively new to jquery and am still learning.

I was thinking along the lines of the validate function but any way to get my desired result would be nice.

Answer 1

if ($.trim($('#field1').val())!=="" || $.trim($('#field1').val())!=="" ) {
    // you're okay
} else {
    // both of them are blank
}

You need to test for (non-)equivalence to a blank string, or else entering the value 0 will be evaluated as false.
