Field Data validation

[aastha3]

Looking for field data validation

1. It should start begin with an alpha character

2. Can only be (a-z) lower case

3.(0-9) numbers

4. "-" (hyphen) character.

Please also suggest if it should work on Onload , On change or onsubmit.

There is a field   of a catalog named hostname(single text line) on which this validation is required.

Thanks

Try below:-

var regexp=/^[a-z]{1}[a-z0-9-]*$/;

if(!regexp.test(newValue)){

alert('Please enter valid characters');

g_form.setValue('ur_name','');

}
