如何使用javascript和php启用或禁用组合框内的值

问题描述：

I want to enable/disable value inside <select> tag based on value from PHP.

The variable is $gender.

If $gender = female then value(Menstruasi) = enabled

else if $gender = male then value(Menstruasi) = disabled

Here is the code :

<select name = "keterangan_cuti_khusus">
<option value="" selected> - = - </option>
<option value="Insidental">Insidental</option>
<option value="Pengembangan_skill">Pengembangan Skill</option>
<option value="Ibadah_Haji">Ibadah Haji</option>
<option value="Masa_kerja">Masa Kerja</option>
<option value="Melahirkan">Melahirkan</option>
<option value="mensturasi">Mensturasi</option>  
</select>

I want

<option value="mensturasi">Mensturasi</option>  <--- disable/enable -->

change where gender is female or male.

Is there any ideas ?

我想在＆lt; select＆gt;内启用/禁用 code>值标记 code>基于PHP的值。 p>

变量是 $ gender。 code> p>

 
 如果$ gender = female则值（Menstruasi）=启用 p> 
 
 
否则如果$ gender = male则值（Menstruasi）=禁用 p> 
  blockquote> 
 
  n
