Adding and Removing Event Listeners
Problem
I want to add an event listener to or remove an event listener from a DOM object. (In other words, I have a thing I want to be able to click on and have it do something.)
Solution
FBJS supports the standard addEventListener()
and removeEventListener()
methods that you know and love from traditional JavaScript.
Calling them is as simple as finding your target in the DOM and
passing in your event type and function name:
var myObj = document.getElementById('someId'); myObj.addEventListener('click', otherFunctionName); myObj.removeEventListener('click', otherFunctionName);
Discussion
This is pretty simple, as long as you keep in mind that otherFunctionName
needs to be a defined
JavaScript function, and that your new listeners will join any that
were added in the FBML code (e.g., <div
id="someId" onclick="aFunctionName();">
).
