I have so many selectbox in the page.How can I validate same value exists in the select box
please check my image attached
for eg:
from:1 to :2
from :2 to :2
from :2 to :2
I read it as from 1 to 2 and from 2 and 2 to 2 like that
so my select box should not contain a same value at a time.How can I validate using javscript.
I have mentioned text box,but its a selectbox
Thanks
