I can't make this work on an iPhone browser. Does anyone know why?
I have created a project exactly like in the video, it works on every browser on my computers, but it doesn't work on any iPhone browser.

Whenever I press the send button, it doesn't do anything, not even clean the textbox. It does update every other browsers I have open at the time, except the one in the iphone or any other iphones viewing the same page.
