想让select下拉框的内容可以让用户输入也可以选择
有没有现成的代码?

<select id= "s ">
<option> a </option>
<option> b </option>
<option> c </option>
</select>
<input id= "i "> <input type= "button " onclick= "c() " value= "改变 ">
<script>
so = document.getElementById( "s ");
io = document.getElementById( "i ");
function c()
{
for(co=0;co <so.length;co++)
{
if(so.options[co].text==io.value) so.selectedIndex=co;
}
}
</script>
