如何在每次加载页面时在javascript中切换1个布尔值，而没有localstorage或cookie？

Question

I need to toggle a boolean every time the page loads. I can't use localStorage OR cookies.

I've tried using localStorage and cookies. problem is that i'm in a sandbox that doesn't allow that.

What I CAN do is do requests to webpages. Maybe one can toggle between returning true or false every time a website loads; like:

First load:

HTTP GET returns true (or 1, it's just an example)

Second load:

HTTP GET returns false (or 0)

Third load:

HTTP GET returns true (or 1)

ETC.

Is there an existing API or something for that?

You can use hash, something like:

<span id="result"></span>
<script>
    if (window.location.hash == '#1') {
        document.getElementById('result').innerHTML ='0';
        window.location.hash = '0';
    } else {
        document.getElementById('result').innerHTML ='1';
        window.location.hash = '1';
    }
</script>
