Hello,
I've got a javascript function that clears a drop down menu, but it seems
that if there's too many items it doesn't clear them all. Is there anything
wrong with the function?
Also, is there any way I can compress this down and make it a generic function?
function clear(DropNum){
if (DropNum == 1||DropNum == 0) {
with (window.document.qsearch.RegionID) {
for (var i=0;i<options.length;i++){
options[i]=null;
}
options[0]=new Option('--------------------------', '0');
}
}
if (DropNum == 2) {
with (window.document.qsearch.RegionID2) {
for (var i=0;i<options.length;i++){
options[i]=null;
}
options[0]=new Option('--------------------------', '0');
}
}
if (DropNum == 3) {
with (window.document.qsearch.RegionID3) {
for (var i=0;i<options.length;i++){
options[i]=null;
}
options[0]=new Option('--------------------------', '0');
}
}
}
Cheers
mk
