restore? translate macromedia code

[freaksarise]

I am looking at some Dreamweaver code to help learn. Could someone translate the line " if (restore) selObj.selectedIndex=0 "

The code is seen below:

function MM_jumpMenu(targ,selObj,restore){ //v3.0
eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");
if (restore) selObj.selectedIndex=0;
}


I dont understand the condition. There appears to be none. And I also can't find the definition of RESTORE. Finally I do not understand the purpose of this line.

Thanks

restore would be a true(1) or false(0) sent to the function.
what that line does is set the selcet to the first item.

It is so when A person goes to reuse it and wants to go back to the same page they can. If this did not happen, then they you have to reset it to the default and goto the page due to the onchange....

Is that what you wanted?

thanks. I changed the code 2 ways:
- i tried it with this line removed
- then i tried it with the value set to 1

there were no differences when clicking the back button or when refreshing/reloading.

I was thinking that you meant the following:

- user makes selection. page is redirected to new location.
- when user either clicks back, or clicks back and then refreshes the page ; the form field will remain as they input last instead of resetting to the default values.

No matter what I did the values stayed as the value the user selected.

Any thoughts?
Thanks

try using the word true instead of one.....Could also be the browser....Or I could be tired from working on my current project at 3 am........

LOL. I know the feeling.
Here is the full script and form pulldown element.
I tried true and false but still no difference. I am in XP Home, using IE 6. Thanks Alien!!
