Drop Down Boxes

[alexisantonakis]

Hi,

I have a drop down list where if a user changes the currently selected option, some js code does a check, and if the user disagrees with it, then the option selected in the drop down list goes back to the original one.

Well that's what I would like to do. I am having problems in getting the drop down list to jump back to the original option.

I have the following code so far:

document.form3.regCountry[Code].checked=true;

where 'regCountry' is the Select box name and 'Code' is the option value I would like to jump to within the drop down list.

Any help would be most appreciated.

Thanks
Alexis

You can change which one is selected like this:

document.form3.regCountry.selectedIndex=2;

That will select the third option. Just change the 2 to whichever option you want to be selected...

Thanks Adam,

That's got it just fine.

Hi All,

Can we select by value..??

The reason is that my select option is built from a table in the database at run time. I cannot use index numbers as the order may change.

Where can I get the full attribute listing for all this HTML stuff.

Thanks in advance.

If you do it like this:

document.formname.selectname.value="Number 2";

it will select the option that has the value of Number 2. I hope that helps! :)

And to change the text value, you use this:

document.formName.selectName.text="Text";

Thanks to AdamBrill
It worked, It worked.........!!!

And Thanks to Jona for the tip.


BTW : Where can I get the full attribute listing for all this HTML stuff and how to get the elements and attributes to work together. Could you please reffer me to a good book or web site where.

Eg.
Details on how to use object attribute ie.
in HTML do <div style="z-index:4">
but in JS do style.zIndex=4

I currently use http://www.w3schools.com but I don't seem to find all the information.
