如何将几个select的值合并
原来是：
<input name= "all " type= "text " id= "all " maxlength= "12 ">
现在用几个select来代替，如何是下面的程序实现像上面的一样。
就是如何将a、b、c、d的四个select值合并成all。
<select name= "a " id= "a ">
<option value= "1 "> 1 </option>
<option value= "2 "> 2 </option>
<option value= "3 "> 3 </option>
<option value= "4 "> 4 </option>
<option value= "5 "> 5 </option>
<option value= "6 "> 6 </option>
<option value= "0 "> 7 </option>
</select>
<select name= "living_rooms " id= "b ">
<option value= "0 "> 0 </option>
<option value= "1 "> 1 </option>
<option value= "2 "> 2 </option>
<option value= "3 "> 3 </option>
<option value= "4 "> 4 </option>
</select>
<select name= "bathrooms " id= "c ">
<option value= "0 "> 0 </option>
<option value= "1 "> 1 </option>
<option value= "2 "> 2 </option>
<option value= "3 "> 3 </option>
<option value= "4 "> 4 </option>
</select>
<select name= "exposure " id= "d ">
<option> =选择= </option>
<option value= "1 "> 1 </option>
<option value= "2 "> 2 </option>
<option value= "3 "> 3 </option>
<option value= "4 "> 4 </option>
<option value= "5 "> 5 </option>
<option value= "6 "> 6 </option>
<option value= "7 "> 7 </option>
<option value= "8 "> 8 </option>
<option value= "9 "> 9 </option>
<option value= "10 "> 10 </option>
</select>
