making validation on combo box having dynamic name

hi...
I have a while loop in which loops through a number of records .. now supposing my while loop has fetched 5 records ..then in the <TD> i will have 5 combo box one below the other ... the name of the combo are:
while(rs.next)
{
combo = combo+1;
}
so the name of the 5 combo boxes is combo1,combo2,combo3,combo4,combo5...same if their are 10 combo then the name will go till combo10....
I have the intial value of the combo box as select . ... now in the java script how will i validate on these dynamic combos ... making sure that the user doesn't leave the value of any of the combo as "select" ???

any ideas .....

thanxs in advance..!

you can use
var sl = document.getElementsByTagName("select");
for(var i=0;i<sl.length;i++){
if(sl[i].name.indexOf("combo") == 0){
.... validate it .....
}
}
Also, it mught make sense to have all comboboxes named the same.
than you will do
var sl = document.getElementsByName("combo");
and no need for check inside the loop.
If you use JSP, on a server you do
String[] combos = request.getParameterValues("combo").
thanks, Yuriy

hi all..
yuriy.... since i'm not too good with java script i yet don't understand the technicality that lies behind it.... can u tell me what does this getElementsbyTagname mean...???
i didn't quite understand.....!!!
and for this loop .. .......
for(var i=0;i<sl.length;i++){
if(sl[i].name.indexOf("combo") == 0){
.... validate it .....
}
}
sl[i].name.indexOf("combo") == 0 ..... the value that is there in the quote ...i.e. "combo"..is it the name of the combo box.....if it so ... then how will i know the name of the combo box as the name is dynamic..!!!
please do tell..!!!
thanxs a lot..!

getElementsByTagName function returns you array of pointers to elements of specified tag. In our case - array of pinters to all SELECT elements on a page. I am assuming not all of them are the once you are looking for.
Even though names for your elements are dynamic, you bulding it somehow.
from your example your select elements always have a name starting with prefix "combo" - combo1, combo2 .... This is what that indexOf checks.
So if select elemnt have a name starting with "combo" - you validate it.

Thanx yuriy... i understood it now...! thank you..!
