有的时候需要手动调用来刷新界面，比如非动态切换的语言模式啊，风格样式啊什么的。
<!DOCTYPE html> <html> <head> <meta charset='utf-8'> </head> <body> <button>location.reload();</button> <button>history.go(0);</button> <button> location=location ;</button> <button>location.assign(location) ;</button> <button>location.replace(location) ;</button> <script> function click1 () { //刷新清缓存，相当于Ctrl+F5：location.reload(true) //普通刷新：location.reload() location.reload(); } function click2(){ history.go(0); } function click3(){ location=location; } function click4(){ location.assign(location) ; } function click5(){ location.replace(location) } </script> </body> </html>
