Javascript Window Event Handling Manager
Join the DZone community and get the full member experience.
Join For FreeI've seen a lot of window.onload managers, so I generalized it for any window event handler. This assumes prototype.
// BurntoEventManager
// http://brentfitzgerald.com/
// January 2007
var BurntoEventManager = {
handlers: {},
add: function(handler_name, method) {
if(this.handlers[handler_name] == null) {
this.handlers[handler_name] = new Array();
}
this.handlers[handler_name].push(method);
// Now update the window event handler
window[handler_name] = function(evt) {
this.handlers[handler_name].each(function(m) {
m(evt);
}.bind(this));
}.bind(this);
},
clear: function(handler_name) {
this.handlers[handler_name] = null;
window[handler_name] = function() {};
},
get: function(handler_name) {
return this.handlers[handler_name];
}
}
For example, consider if later on in our application we want to add an onclick handler.
BurntoEventManager.add("onclick", function(evt) { alert(evt) });
