html页面 加载完成后再刷新 一次

第一种推荐：

<script>
function refresh(){
if(sessionStorage.getItem("isReload")){
   console.log("页面被刷新");
}else{
 console.log("首次被加载");
window.location.reload();
sessionStorage.setItem("isReload", true)
}
}
window.onload = refresh;
</script>

第二种

<script>
function refresh(){
url = location.href;
console.log(url);
var once = url.split("#");
if (once[1] != 1) {
url += "#1";
self.location.replace(url);
window.location.reload();
}
}
setTimeout('refresh()', 1000);

</script>

第三种综合一二

<script>
function refresh(){
window.location.reload();
}

function refresh2(){
if(sessionStorage.getItem("isReload")){
   console.log("页面被刷新");
}else{
 console.log("首次被加载");
 sessionStorage.setItem("isReload", true);
 setTimeout('refresh()', 100);

}
}
setTimeout('refresh2()', 10);
</script>
