Re: [jQuery] What tools should I use to troubleshoot jquery problems? (John Resig, jquery team, other gurus please share your tricks...)

[Ⓙⓐⓚⓔ]

Mike, I don't like breaking the chains... I just insert a debug in the
middle of the chain...

I use this for my debug:
jQuery.fn.debug = function(message) {
        return this.log('debug:' + (message || '')
+"[").each(function(){jQuery.log(this);}).log("]");
}
jQuery.fn.log = jQuery.log = function(message) {
        if (!message) message = 'UNDEFINED'
        if (typeof message  == "object") message = jsO(message)
        if(window.console && window.console.log) //safari
                window.console.log(message)
        else if(window.console && window.console.debug) //firebug
                window.console.debug(message)
        else
                jQuery("body").prepend(message+ "<br/>")
        return this
}
