1. If it is particularly important or requires a long time to edit the content suggested setinterval Ajax to save the user's draft information to the database (Memcache, Redis better) This can also achieve the browser
2. If it is not important, determine whether the user's browser supports HTML5 localstorage saved in Localstorage if it is not supported in the cookie store but the cookie does not save too much data because each request will pass a cookie
