页面控制台报错：

状态码：canceled 

原因分析：

这是一个很明显的get请求方式，而login操作请求是由DOM节点$(‘#’)通过post方式实现的。

可以肯定的是，有个操作将post请求干扰了。分析排查后发现是由于form标签导致的。

------------------------------------------------------------------------------------------------------------

原因:

仅仅是由于之前为了在输入账号时让浏览器进行自动补全，而将原先的div更换为了form,而不巧的是之前的登录事件源使用的是button。

而至于为什么status = canceled,是由于在提交时，form action与绑定于button上的click事件会同时触发。form action将表单内容以serach的形式追加至当前url上，url变更后会导致页面重新加载， 而这正是导致post请求在执行后就被终止的原因。
总结：

1.在URL变更后，会对当前正在执行的ajax进求进行中止操作。中止后该请求的状态码将为canceled 

2.在使用到ajax的时候，尽量不要在form内使用button进行提交，这些特殊的标签在特定的情况下往往会有让你迷茫的时候。

解决方式：

调整jsp页面的<form>标签 和 <button>标签。即可解决
