<option value="">-- Difficulty --</option>
<option value="1">Easy</option>
<option value="2">Medium</option>
<option value="3">Difficult</option>
</select>
<select id="numbList"></select>
<script>
window.difficulty = {};
window.difficulty['1'] = [1,2,3];
window.difficulty['2'] = [4,5,6];
window.difficulty['3'] = [7,8,9];
function changeList() {
var diffList = document.getElementById("diffList");
var numbRange = document.getElementById("numbList");
var selectDiff = diffList.options[diffList.selectedIndex].value;
while(numbRange.options.length)
{
numbRange.remove(0);
}
var diff = window.difficulty[selectDiff];
if(diff)
{
var i;
for(i = 0; i < diff.length; i++)
{
var difficulty = new Option(diff[i], i);
numbRange.options.add(difficulty);
}
}
}
</script>
