Angular.js 只能在一个页面上工作和保存数据.如果您的页面重新加载(正如您在说express.js 加载下一页"时似乎表明的那样)，那么它会重新初始化所有内容.

Angular.js only works and keeps data on a single page. If your page reloads (as you seem to indicate when you say "express.js loads the next page", then it reinitialized everything.

你应该:

• 使用一些东西来保存你的数据，比如 localstorage.了解更多:http://diveintohtml5.info/storage.html

• look at how to use Angular.js routing (http://docs.angularjs.org/tutorial/step_07) so that you stay on the same page.
• use something to persist your data, such as localstorage. Find out more: http://diveintohtml5.info/storage.html
