first 3 characters

[kpj]

Hi All,

I am trying to populate name field on another field through client script. But I want only first 3 characters to be auto-populated. Please share your thoughts on how to achieve this?

Appreciate you Help!!

Thank you,

Jack

Hi Jack,

You would do something like this with an onChange client script on field1.

var str = g_form.getValue('field1');

g_form.setValue('field2', str.substring(0, 3));

Modify 'field1' to be the name of your source field and 'field2' to be the name of your target field.

Can we also remove special characters?

You can do that with a .replace() function using a regular expression.

str = str.replace(/[^a-z0-9]/gi, ''); // strip out anything that's not a letter or number
