获取select option中的value和text

如果想获得下拉列表框的value，需要通过这种方式
<script language="javascript">
function selectInput(choose)
{
   alert(choose.value); //this.value
   alert(document.all.month.value);//这个是另外种获得下拉列表框的值
}
</script>
<select name="month" onchange="selectInput(this)">
         <option value="01">January</option>
         <option value="02">February</option>
         <option value="03" selected=”selected”>March</option>
         <option value="04">April</option>
</select>

如果需要获取他的text，首先需要获得取下标值，再通过下标值来获取text
<script language="javascript">
function selectInput(choose)
{
   //首先获得下标，再取获得对应的text
   alert(choose.options[choose.selectedIndex].text);
}
</script>
<select name="Month" onchange="selectInput(this)">
         <option value="01">January</option>
         <option value="02" selected=”selected”>February</option>
         <option value="03">March</option>
         <option value="04">April</option>
</select>
