I solve all examples locally and can’t find the starting file in this test , so i downloaded The solution (its name is same as starting files as in previous but it is solved) and removed the solved code ( i really solved it myself , so happy).
I download this the sample json file too.
I stored them both on a same folder and it worked fine. But on the test it’s written cross origin security something so we can’t do it locally. But i think we can do it this way because both are on same origin. So i think you update the test page with this. And also it’s simple no complex things used.
In case i am wrong i am happy to hear it.
The test of which i am talking about.
This is the test
