I have Ajax in the bottom of the page. I am sure why is it not triggering on iPhone Safari. or maybe it is being executed, but there are some errors.
Note :
- that same code on Chrome or Safari on Mac OS X. ✅
- Ajax does triggered, and working fine. ✅
Ajax does not seem to trigger on iPhone Safari
Am I using any old syntax that Safari on iPhone not recognize ?
How would one go about and debug this further?
from How do I check status of my Ajax request running on my iPhone Safari?
