Summary of several methods for refreshing the current page using JS

reload method, this method forces the browser to refresh the current page. At grammar: Location.reload ([BFORCEGET])

Parameter: BFORCEGET, optional parameter, default to False, take the current page from the client cache. If true, the latest page is fetched from the server in GET mode, which is equivalent to the client clicking F5 ("Refresh")

replace method. This method replaces the item currently cached in the history (client) by specifying the URL, so After using the replace method, you cannot access the replaced URL through "forward" and "back".

Syntax: location.replace(URL)

In actual application, when refreshing the page, we usually use: location.reload() or history.go(0) to do it. Because this approach is like the client clicking F5 to refresh the page, so when the page's method="post" is used, a "webpage expired" prompt will appear. That's because of Session's security protection mechanism. You can think of: When the location.reload() method is called, the aspx page already exists in the server memory, so it must be IsPostback. If there is such an application: We need to reload the page, which means we expect the page to be re-created on the server side, and we expect Not IsPostback. Here, location.replace() can accomplish this task. The replaced page is regenerated on the server every time.

You can write like this: location.replace(location.href);

Return and refresh the page:

location.replace(document.referrer);

document.referrer //URL of the previous page

Don’t use history .go(-1), or history.back(); to return and refresh the page. These two methods will not refresh the page.
