Synchronous Xmlhttprequest On The Main Thread Is Deprecated... Tried Many Different Solution

I know this question was posted so many times in here, but I tried all the solutions I could find on stack overflow and none of them worked. I'm just trying to make a simple ajax q

Solution 1:

You should use local jquery then from cdn and also

To avoid this warning, do not use:

async: false

in any of your $.ajax() calls. This is the only feature of XMLHttpRequest that's deprecated.

The default is async: true, so if you never use this option at all, your code should be safe if the feature is ever really removed (it probably won't be -- it may be removed from the standards, but I'll bet browsers will continue to support it for many years).

Referance

Solution 2:

I also notice the same problem when using the .load() function.

The method seems not deprecated by jquery but it causes Synchronous XMLHttpRequest alert too.

Prefer $.get(), $.post(), or $.ajax() methods instead.
