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

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || newValue == '') {

          return;

    }

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

  if(!regexp.test(newValue)){  

  alert("Please enter valid characters.It should start with lowercase alpha character, include [0-9] and hyphen");  

  g_form.setValue('host_name', '');  

  }  

}

PS: Its working correctly but just wanted to know why that warning is coming

M not getting any warning message if I save the same code...can you try refreshing and see...code is fine..

It might be showing old error.

Yes its getting saved and not showing any warning . It only shows warning if I click check syntax button situated above where we write code.

Aastha,

      Write an onChnage client script on the hostname variable add this in your script for validation

if(/^[a-z]{1}[a-z0-9-]*$/g.test(newValue)){

//do nothing

}

else{

alert('Please enter valid characters");

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

}

Thanks,

Abhinay

Its giving error : Unescaped -

Then I tried using /^[a-z]{1}[a-z0-9"-"]*$/ still its not working for hyphen.

If I use hyphen then also its giving me alert message.
