給select增加placeholder技巧

思路1:

使用預設的option 再隱藏此選項

<select>
    <option value='' disabled selected style='display:none;'>Please Choose</option>
    <option value='0'>Open when powered (most valves do this)</option>
    <option value='1'>Closed when powered, auto-opens when power is cut</option>
</select>

 

思路2:

使用預設option再disabled此選項

<select>
    <option value="" disabled selected>Select your option</option>
    <option value="hurr">Durr</option>
</select>
