This is just a small function I created to see the structure of an event object in the log i recieved from phonegap. It's great for everyone that hates the "[object Object]" string in their logs.

debug_object_as_string.js

function stringDebug(sender, method, object) {
    var tostring =Object.prototype.toString;
    Object.prototype.toString = function(padding) {
        padding  = padding || 3;
        var res = Array(padding-2).join(" ")+"{";
        var _self = this;
        for(var attr in _self) {
        res += '\n' + Array(padding).join(" ") + attr + " : " + ((this[attr] && (padding +2) < 12) ? this[attr].toString(padding +2) : "null");
        }
        return res+"\n"+Array(padding-2).join(" ")+"}";
    }
    sender[method]("debug: "+ object);
    Object.prototype.toString =  tostring;
}

(function example() {
    var object = {
        you : "see",
        even : {
            "this" : "rather"
        },
        complicated : {
            object : {
                is : "stringable",
                loop : object,
                "function" : function(param) {
                    console.log("this is a function");
                    return param;
                }
            }
        }
    };
    //alert example
    stringDebug(window, "alert", object);
    //console log
    stringDebug(console, "log", object);
    /*  Output:
