I can't get the button to call my javascript function and I'm starting to run in circles. I'm not very experienced in this area and to me it looks like all the examples I've seen.

Im testing everything on the iPhone Simulator by the way.
Thanks for your help
There is a typo in the first line in login()
with document.getElementById()
and i have done some code changes in the login()
with style
display
Properties.
Check out comments in code, and you will get an idea
function login() {
//initialize login
var parentElement = document.getElementById('deviceready'); // getElementById <- Not ID
var notConnectedElement = parentElement.querySelector('.notConnected');
var connectingElement = parentElement.querySelector('.connecting');
//notConnectedElement.setAttribute('style', 'display:none');
//connectingElement.setAttribute('style', 'display:block;');
notConnectedElement.style.display = 'none'; // Newly Added
connectingElement.style.display = 'block'; // Newly Added
alert("Hello world!");
}
我不知道为什么,但是当我将函数调用放在form标记内时,它可以工作
<form action="javascript:login()">
