Question

Excuse me, how can Angular realize that when editing content without clicking Save, you can still see the content you edited when you return?

Answer 1

Listen to the input event, save the entered content to localstorage, and load the content in localStroage when loading the page.

Answer 2

You can tie the ng-model of input to the data model of rootscope, so that the data can be retained when the front-end virtual router switches pages.
