问题
I run my tests with Karma and PhantomJS:
INFO [karma]: Karma v0.12.32 server started at http://localhost:9876/ INFO [launcher]: Starting browser PhantomJS INFO [PhantomJS 1.9.8 (Windows 7)]: Connected on socket kVOvdbbgtIeUQuV8AAAA wit
In the that test I want to click on the paragraph (p) to get my event-feedback:
// given
var element = appendToBody("<p id='hello-p'>Hello Hello World!</p>");
element.addEventListener('click', function(event) {
console.log("1");
});
// when
var p = document.getElementById("hello-p");
console.log(p);
// LOG: <p id="hello-p">Hello Hello World!</p>
console.log(p.id);
// LOG: 'hello-p'
p.click(); // calling click
I end up having this message:
TypeError: 'undefined' is not a function (evaluating 'p.click()')
Q: why p could be undefined?

Ok. Bacause PhantomJS based on webkit, I have to create/send event like this:
var cle = document.createEvent("MouseEvent");
cle.initEvent("click", true, true);
var elem = document.getElementById('hello-p');
elem.dispatchEvent(cle);
