Microsoft Visual Studio移动Web窗体中调用javascript的问题

Question

各位老师好

下面是我的问题

我们这个学期是学习了asp.net手机网络的

期末项目我是想做一个亲子网

需要把很多网页代码移植成为移动web窗体代码

现在我是想做一个预产期计算器，地址http://www.pcbaby.com.cn/tools/ycq/

我在移动web中已经把所有需要的组件都建立好了

现在的问题就是

如何使用一个按钮调用下面这些代码

<script language="javascript" type="text/javascript"> 

function haha()

{

if (health.year.value=="" || health.month.value=="" || health.day.value =="")

{

alert("请填写完整年月日!");

return false;

}

{

alert("请填写正确年份!");

health.year.focus();

return false;

}

{

alert("请填写正确月份!");

health.month.focus();

return false;

}

{

alert("请填写正确日子!");

health.day.focus();

return false;

}

{

alert("年月日组合有错,请重新填写!");

return false;
