Stopping the scrollable feature in select box

Question

hi,
in my jsp page i have a select box with some values..
<select name='sel' onchange="window.form.submit()"></form>
<option value='india'>india</ption>
<option value='usa'>usa</ption>
<option value='uk'>uk</ption>
</select>
once i select value from the select box the onchange is called and submitted to form again.but some times it takes more time for onchange and the cursor will be in select box..during this time if we move the mouse scrollabe then the value in select box is changed and
onchange is perfomed more than once and it throws exceptions..
how can i stop the user from scrolling once he selects a value..
regards,

Answer 1

you may disable the select box before submitting..
or perhaps use an onchange function that maintains a status var like this (untested!) :
var onChangeRunning = false;
function sel_onChange() {
    if (!onChangeRunning) {
        onChangeRunning = true;
        //do submit form stuff
        onChangeRunning=false;
}and call this in the onchange-handler of your select box instead of directly submitting the form..
just two ideas, I'm sure there are more ways to do ensure this...
