问题
I have a plunker to set a value in localStorage:
<!DOCTYPE html>
<html>
<script>
localStorage.setItem('test', "hadddddha");
</script>
</html>
And I have a code http://www.addbba.com/testLocalStorage.html to get it:
<!DOCTYPE html>
<html>
<script>
var test = localStorage.getItem('test');
console.log(test)
</script>
</html>
Oddly, the console shows the value is null. Does anyone know what happened?

According to https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage localStorage is specific to a document's origin. Can you confirm that you are reading a value from localStorage using the same origin as where you wrote the value?
