<option value="5">5</option>
<option value="6">练习一</option>
<option value="7">练习二</option>
<select>
<script type="text/javascript">
var myselect=document.getElementById('Select');//获取select对象
console.log(myselect);
var index=myselect.selectedIndex;//获取选项索引(value)
console.log(index);
/*var s1=myselect.option[index].value;
console.log(s1);*/
