jsp中onchange事件调用后台回显页面发生路径叠加样式改变

jsp中代码

function count(obj){
var tradeDateFrom = document.getElementById("tradeDateFrom").value;
var tradeDateTo = document.getElementById("tradeDateTo").value;
window.location.href ='mistakeCollect/BalanceMistakeCollect?tradeDateFrom='+tradeDateFrom+'&tradeDateTo='+tradeDateTo;
return null;
}

有两种办法可以解决：
1、window.location.href ='mistakeCollect/BalanceMistakeCollect?tradeDateFrom='+tradeDateFrom+'&tradeDateTo='+tradeDateTo;
改为：
window.location.href ='BalanceMistakeCollect?tradeDateFrom='+tradeDateFrom+'&tradeDateTo='+tradeDateTo;
2、设置部署后的项目名为空
window.location.href ='/mistakeCollect/BalanceMistakeCollect?tradeDateFrom='+tradeDateFrom+'&tradeDateTo='+tradeDateTo;

推荐使用ajax局部刷新
