firefox里不支持onChange事件，我想实现这个功能该怎么做？

Question

我在select里加了onChange事件，在IE里没事，在FF里不触发该事件

Answer 1

如果选择相同的,当然不会触发ONCHANGE事件了!!

Answer 2

帮我看看这段吧
<select name="selSource" onChange="changelocation(document.getElementById('selSource').options[document.getElementById('selSource').selectedIndex].value)">
<option value="en">English</option>
<option value="jap">日语</option>
</select>
<select name="selTarget">
</select>
<script>
subcat=new Array();
subcat[1]=new Array("阿拉伯语","en","ab");
subcat[2]=new Array("English","jap","en");
subcat[3]=new Array("日语","en","jap");
var count=3;function changelocation(code)
    {
    document.getElementById('selTarget').options.length = 0; 
    var code=code;
    var i,seltar;
    for (i=1;i <= count; i++)
        {
if (subcat[i][1] == code)
{ 
document.getElementById('selTarget').options[document.getElementById('selTarget').options.length] = new Option(subcat[i][0], subcat[i][2],true,true);
} 
        }
    }</script>
