js取select的值

[xiongbing529]

<select name="payway_id" onchange="location.href='right.php?action=changepayway&orders_id=表单select里面的值">

<option value=1>a</option>
<option value=2>b</option>

</select>

我想跳转到right.php?action=changepayway&orders_id=1
这里的 1是取自option 的 value

请问 js怎么写啊 。

[s_liangchao1s]

this.options[this.selectedIndex].value

[lawrendc]

document.getElementsByName("payway_id")[0].options[document.getElementsByName("payway_id")[0].selectedIndex].value;

o 好长

<select name="payway_id" onchange="change_event(this)">
<option value=1>a </option>
<option value=2>b </option>
</select>

<script>
function change_event(sef){
try{
var orders_id = sef.options[sef.selectedIndex].value;
location.href='right.php?action=changepayway&orders_id='+orders_id;
}catch(e){}
}
</script>
