javascript - 一般登陆的时候提交用form表单提交好?还是用ajax好?
想问下在登陆页面的时候使用form表单提交好还是用ajax提交好?
如果是用安全性来区分的话,应该首选哪个?
还有就是form表单和ajax的用途?什么时候该用form什么时候该用ajax?

安全性都一样。
安全性与你的提交文件的业务处理(格式检测,防注入)有关,与提交方式无关。
通常表单提交,ajax通常用在浏览查看,操作小部件等提高用户体验
本人比较习惯用Ajax,Ajax提交是通过js来提交请求,请求与响应均由js引擎来处理,页面不会刷新。对于登陆功能,如果用户输入的用户名或密码错误,则可以在相应的页面给出错误提示。
楼上说的没错
建议用ajax吧,这样可以不刷新整个页面,达到局部刷新的效果
这个和安全性没有关系,都是发送的http协议,form表单与ajax提交都行,你想要什么用户体验,就用那种。
纯 ajax 会有个隐藏的问题 那就是浏览器不提示保存密码 这个在用户体验上我看来是反人类的
理想的ajax方式:
建立隐藏的iframe 把form标签的 target指向iframe,然后检测 iframe 的状态
难道不是看需求嘛。
有的登录表单和登录后页面不是在一个页面啊
