不同文本框改变都能获取到值

怎么让 图片上画三个红框的 改变了也可以用我的js里面的那个方法去计算

下面那个利息总额 出现了NaN 是我在 html 里写了 onChange="gross_interest(this)"
但是他不对
下面的我圈住那个是 怎么用这段代码 获取那个var o 里的name属性 $('#dw,#dw1,#dw2').val(this.options[this.selectedIndex].getAttribute('name')); 这个获取不到 这个获取到 只是var o里的id值$('#dw,#dw1,#dw2').val(this.options[this.selectedIndex].text);
