JS获取select-option text

Js代码  

 

 function selectInput(choose)
 {  
   alert(choose.text); 
 }

 写JS的时候 获取select对象的value是很常见的事情 例如

Js代码  

<script language="javascript">
 function selectInput(choose)
 {  
   alert(choose.value); 
 }
</script>
<select name="month" onchange="selectInput(this)">
         <option  value="01">January</option>
         <option  value="02">February</option>
         <option  value="03">March</option>
         <option  value="04">April</option>
         <option  value="05">May</option>
         <option  value="06">June</option>
         <option  value="07">July</option>
         <option  value="08" selected="selected">August</option>
         <option  value="09">September</option>
         <option  value="10">October</option>
         <option  value="11">November</option>
         <option  value="12">December</option>
</select> 

 这样子就可以获得 month的值了 也就是01 02 03... 但是value所指向的text呢？ 用一般的方法

 

这样子是获取不到的~ 那我们则需要另一种方法获取

<script language="javascript">
  function selectInput(choose)
 {
   alert(choose.options[choose.selectedIndex].text);
 }
</script>
 <select name="Month" onchange="selectInput(this)">
          <option  value="01">January</option>
          <option  value="02">February</option>
          <option  value="03">March</option>
          <option  value="04">April</option>
          <option  value="05">May</option>
          <option  value="06">June</option>
          <option  value="07">July</option>
          <option  value="08" selected="selected">August</option>
          <option  value="09">September</option>
          <option  value="10">October</option>
          <option  value="11">November</option>
          <option  value="12">December</option>
</select>
