通过javascript / jquery限制浏览器刷新，f5，像银行网站一样返回浏览器

Question

你们中的一些人知道某些银行网站中的F5，浏览器刷新/后退按钮功能...像那样，可以使用跨浏览器的任何方式来使用javascript / jquery控制浏览器功能

Answer 1

(1) No. There no possible cross-browser way to control browser functionality with javascript/jquery.

(2) Banking sites do not restrict or control the browser functionality. They only ask users to desist. At most they attempt to detect some actions and then show errors. But, they don't try to control the browser.

(3) This is a bad idea.

Answer 2

Back in the day some banking sites would spawn a new window in javascript without any browser chrome. This doesn't disable refreshes and page navigation, but it makes it a little less likely that novice users will initiate them.

I believe most banking sites these days just disable the page caching and show an error message telling you not to refresh the page if you reload of press back, in combination with some server side tracking of your navigation.
