howto initial select in option ?

hi good day,

if i have an option as show

and i would like to set the index from very beginning for the option(eg

nload)

how to i set it ? say if i would like to set value3 as default selected item
in javascript, can someone please show me ?

eric , it must use a for loop to check the value? we can't set it by just giving the value ?

Did you try?

Eric

eric, i try on this basic sample, but i can't call the value

it give me error "options is null or not an object"

what mistake occur in my code ?

thank you eric for the example
