How to refresh the current page? With js you can do anything.

1, reload method, this method forces the browser to refresh the current page.
Syntax: location.reload([bForceGet])
Parameters: bForceGet, optional parameter, default is false, retrieve the current page from the client cache. true, then use GET method to fetch the latest page from the server, which is equivalent to the client clicking F5 ("Refresh")

2, 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)
Usually use: location.reload() or history.go(0) to do it.
This method is similar to the client pressing F5 to refresh the page, so when the page method="post", a "webpage expired" prompt will appear.
Because of Session’s security protection mechanism.

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: The page needs to be reloaded, which means that the page is expected to be re-created on the server side, and the expectation is Not IsPostback.
Here, location.replace() can complete this task. The replaced page is regenerated on the server every time.
Code: location.replace(location.href);

Return and refresh the page:
location.replace(document.referrer);
document.referrer //URL of the previous page
Do not use history.go(-1) , or history.back(); to return and refresh the page. These two methods will not refresh the page.
