Yes, I have included everything. Actually it works perfectly without the button. But when I add the button, clicking the button doesn't display the expected text

You put onlick() instead of onclick(). You're missing the "c" in "click".

<button id="load" onlick="sendAJAX();">

Yeah, you put "onlick" instead of "onclick" but I see another mistake, you put a semicolon at the end of "sendAJAX();", remove that semicolon so it its "sendAJAX()", without the semicolon.
