How to get value(s) from Multiple Selection enabled Select Box

[Raghuram Banda]

Hi All,

I'm on a task some thing like getting selected value(s) from source
SELECT box and appending these value(s) to destination SELECT box. Can
anyone help me how to get multiple values from SELECT box using
JavaScript (DOM).

Thanks in advance.

If the select element is "selRef", we can iterate through the selected
options as:

for (var i=selRef.options.length-1; i >= 0;i++) {
if (selRef.options[i].checked) {
// do something
}
}

I count backwards, so if you remove the option you are looking at,
it will not affect the ones you haven't visited yet.

if (selRef.options[i].checked) {

And this should be
if (selRef.options[i].selected) {
I hate it when I reflexively press submit before testing.
