Location Related:

Method name	Method description
Assign (url)	The current page opens a new URL and generates a record in the browser history that, like the settings window.location and Location.href effects, can be returned back to the previous page
Replace (url)	The current page is replaced with a new URL page content that does not generate a record in the browser history, so it is not possible to return the previously replaced page by hind legs
Reload (force)	If fore is true, attempts to force the current page to be refreshed from the server, or false to refresh the current page from the cache

After 1 seconds the page is replaced by Baidu SetTimeout (function () {location.replace (' http://www.baidu.com ')},1000)//intermittent Refresh under Page setinterval every 2 seconds ( function () {location.reload (true)}, 2000)

Description: code after the reload () call may or may not be executed, depending on factors such as network latency or system resources, so it is best to put reload () in the last line of code
