How to get first character in a name.

[User267]

This are two fields in catalogue form.

PH last name- Mary

Check digit- when you entered something in field"PH last name" then the starting ( First character) letter of name will.

[sushantmalsure]

have you tried above onChange() script to be created on catalog item?

Have you replaced the variables with correct variable name?

I hope both these fields are string?

In check digit I need to get first character from PHname. So in your code there is no pH name right? How it will be working

[sushantmalsure]

I am using that under newValue as the client script is written on change of PH last name.

my code works perfectly and tested on my PDI.

i think you are not getting what is explained above .

Hi @User267 ,

Hope you are doing great.

Create on change client script on last name field and try usig below script in onchange function:

  var lastnameField = g_form.getValue('lastname');
  if (lastnameField.length > 0) {
    var firstCharacter = newValue.charAt(0);
    g_form.setValue('check_digit', firstCharacter);
  } else {
    g_form.clearValue('check_digit');
  }
