如何获得select被选中option的value和text

一:JavaScript原生的方法

1:拿到select对象: var myselect=document.getElementById(“test”);

2:拿到选中项的索引:var index=myselect.selectedIndex ; // selectedIndex代表的是你所选中项的index

3:拿到选中项options的value: myselect.options[index].value;

4:拿到选中项options的text: myselect.options[index].text;

二:jQuery方法(前提是已经加载了jquery库)

1:var options=$(“#test option:selected”); //获取选中的项

2:alert(options.val()); //拿到选中项的值

3:alert(options.text()); //拿到选中项的文本
