转到上一个html页面而不刷新数据

Question

Am using onLoad function of html page to fetch the data from server and to update the table rows with angularJS ng-repeat. Whenever I go to another html page and returns back, onload function is executing and it causes a delay. I need to return to the previous html page without refreshing the data.

You've got a couple of options -- the best one tends to be saving a flag inside of a window.sessionStorage and storing the data there as well.

Note that sessionStorage is unique to each window/tab and is temporary, unlike localStorage which is more long term.

You can even set a time/date stamp to determine how old the data can get before it is considered stale and needs refreshed.
