jQuery namespaced event binding/unbinding

to javascript dom ajax js jquery events scraping scrape by jamiew on Jan 12, 2008
// from a comment by Steven Bristol on errtheblog.com

I just wanted to share a really killer event handling tidbit:

Generally you do something like:

jQuery(’.class’).click(function(){//whatever});


Everyone knows this can be rewritten as:

jQuery(’.class’).bind(‘click’, function(){//whatever});


But sometimes you need to unbind something:

jQuery(’.class’).unbind(‘click’, function(){//});


The problem with this is that it will unbind all the click events, not just yours. So if multiple bits of javascript have a click event handler for ’.class’, unbinding removes them all. (This is because there is no way to identify an anonymous function.)

But jQuery is so good that there is a way to handle this: Namespacing your events:

jQuery(’.class’).bind(‘click.namespace’, function(){//}); 
jQuery(’.class’).unbind(‘click.namespace’);


or for reinitializing an element added via ajax:

jQuery(’.class’)unbind(‘click.namespace’).bind(‘click.namespace’, function(){//});

jQuery and Rails' respond_to

to ruby rails javascript rubyonrails ajax js jquery respond_to by jamiew on Jan 12, 2008
// Just throw this at the bottom of your application.js and you’re good to go: all jQuery ajax requests will trigger the wants.js block of your respond_to declaration, exactly like you’d expect. Enjoy.
// via: http://ozmm.org/posts/jquery_and_respond_to.html

jQuery.ajaxSetup({ ‘beforeSend’: function(xhr) {xhr.setRequestHeader(“Accept”, “text/javascript”)} })
