[問題] 下拉式選單<option>
<select onchange='receiver(this)' name="edit_content">
<option value="很好">很好</option>
<option value="普通">普通</option>
<option value="不好">不好</option>
</select>
上述的例子，我要怎麼動態的對某一個<option>加上selected屬性呢？
ex:從database接收到某個值，判斷這個值之後
變成下面這樣
<select onchange='receiver(this)' name="edit_content">
<option value="很好">很好</option>
<option value="普通">普通</option>
<option selected value="不好">不好</option>
</select>
請個位指教 謝謝
