You could use a querystringat the end of the page url (e.g. ?r), and check for it before redirecting, as if it exists, the redirect is already done.
您可以querystring在页面 url 的末尾使用 a （例如 ?r），并在重定向之前检查它，如果它存在，则重定向已经完成。
if(window.location.href.substr(-2) !== "?r") {
window.location = window.location.href + "?r";
}
Disclaimer: I agree with others that you probably have a better solution - and should never need to refresh 'just once'.
免责声明：我同意其他人的看法，您可能有更好的解决方案 - 并且永远不需要“只刷新一次”。
Explanation of use
使用说明
At the bottom of your page, just above the </body>you should put this:-
在您的页面底部，就在上面，</body>您应该放置以下内容：-
<script type="text/javascript">
if(window.location.href.substr(-2) !== "?r") {
window.location = window.location.href + "?r";
}
</script>
That's it.
就是这样。

<script type="text/javascript">
$(document).ready(function(){
//Check if the current URL contains '#'
if(document.URL.indexOf("#")==-1)
{
// Set the URL to whatever it was plus "#".
url = document.URL+"#";
location = "#";
//Reload the page
location.reload(true);
}
});
</script>
Due to the if condition the page will reload only once. Hope this will help.
由于 if 条件，页面只会重新加载一次。希望这会有所帮助。

Here is another solution which works for me using localStorage. In this solution we don't need to modify existing url.
这是另一个使用 localStorage 对我有用的解决方案。在这个解决方案中，我们不需要修改现有的 url。
<script type='text/javascript'>
(function()
{
if( window.localStorage ){
if(!localStorage.getItem('firstReLoad')){
localStorage['firstReLoad'] = true;
window.location.reload();
} else {
localStorage.removeItem('firstReLoad');
}
}
})();
</script>

The only way I can think of to do this is by using cookies (or if your on the right platform, sessions) and flag the first time it has reloaded, variables might also work in this case, because we're speaking about IFRAME, but I have never tried such thing.
我能想到的唯一方法是使用 cookie（或者如果您在正确的平台上，会话）并在它第一次重新加载时进行标记，变量在这种情况下也可能起作用，因为我们正在谈论 IFRAME，但我从来没有尝试过这样的事情。
