is now developing an h5 news site, but in safair, click the back button, the page will be refreshed, and the things loaded asynchronously will be brushed off. To continue to brush down from the beginning, how can you let safair go back without refreshing, or what its refreshing mechanism is, and why some websites do not refresh when they go back?
for example, the very old ones do not refresh: https://wap.win7china.com/
you can use the front-end framework based on url control to achieve the effect, and the website you give is refreshed when you back up, but because of the browser cache, the response is very fast and looks like it is directly displayed
you can use hash to route
