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

Hi Aastha,

You should use it onChange of the field...

Below thread might help you..

Also below expression will fulfill your first three requirement.

var regexp = /^([a-z]){1}(\w*)$/;

Not working to include hyphen "-"

[Deepa Srivastav · Accepted solution]

Try below:-

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

if(!regexp.test(newValue)){

alert('Please enter valid characters");

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

}
