我用javascript编写了一个用于验证表单的ASP页面，然后让它重定向（form.action）到另一个页面，但它只是重新加载页面。这是我的代码：

function ChangeTypeList()
{
var typeList=document.getElementById("Atype");
var coveredList=document.getElementById("typecovered");
var selType=typeList.options[typeList.selectedIndex].value;
while (coveredList.options.length)

coveredList.remove(0);
}
var types=typesAndCovered[selType];
if (types)

coveredList.options.add(Atype);
}
}
}
</script>
<script type="text/javascript">
