What is the value of -- None -- in select box?

[dianemiro]

Hi Everyone,

I know before that the value of -- None -- in select box is blank or ''. I am creating a client script to clear selections if -- None -- is selected in a select box but I can't get it to work. It seems that the value of -- None -- is not '' or blank. Can you help me to confirm what is the value of None?

Thank you,
Diane

it's actually blank

I'm using switch/case in a client script, and neither default nor case: "" detect the change to -- None -- from  another selection.  I'm trying to clear another field if it's selected, and no go.  The other selections are read fine...

EDIT: oops!  forgot to remove "|| newValue === ''"

Hi Diane,

If the None option is because of Dropdown with none then it should be empty.

Can you share the script here?

--None-- is blank. 

You can select none on the form and use javascript executor to check if it different(ctrl+alt+shift+j...then run alert(g_form.getValue('<field name>')))
