Drop down setting

[Paul]

How do I change the selected value of a dropdown list. I need to force this
as if another part of the form changes this should change in sympathy.

I have tried formObj.status.options[4].selected == true, but this doesn't
work

It is at least :

document.formObj.status

with 'document' in 1st place !

and better :
document.forms['formObj'].elements['status']
where 'formObj' and 'status'
are the names of the form and of its element
ARE NOT THE ID ! ! !


Do you want : show item 5 ?

document.formObj.status.selectedIndex = 4;

or : give a new value and new text to that item ?

document.formObj.status.options[4].value = 'something.htm';
document.formObj.status.options[4].text = 'something';

or : whatelse ?

if(document.formObj.status.selectedIndex == 4)
alert(document.formObj.status.options[4].value);

I can barely copy/paste French into a translator so I am not sure what
you are asking. It translates, roughly, to "What you say?"

ekzacktelly !

and I am not
sure if you don't understand what I said

right : I don't understand wanna nor gonna and so on.

function someFunction(formObj){
alert('I have a reference to formObj without using document. first')
}

seen like that ...

Then you agree with my assessment that document. is not "necessary" but
it is dependent on how you get formObj?

Yesss'Sir !

but you as me never will now what was 'formObj' in the question

That is true, but, it is also the reason you can't apply a blanket answer
to it as you don't know how it was obtained. If it was using the IE
shortcut of ID/NAME as a global variable then it could almost be expected
to have been elementObject.value and forget about the form object

Just so you don't lose any sleep 'formObj' was the name of the form passed
to the JS on the call to the function.

I am surprised you did not say something about "ARE NOT THE ID." You
are the one who showed me that it works on either name or ID.
