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 onclick="click1()">location.reload();</button>
<button onclick="click2()">history.go(0);</button>
<button onclick="click3()"> location=location ;</button>
<button onclick="click4()">location.assign(location) ;</button>
<button onclick="click5()">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>
