Great Reminder of the Importance Of Money

I follow an interesting blog that focuses on money from the perspective of Ayn Rand and her amazing book “Atlas Shrugged”.  The posted a great article that I want to link to because this speech by Francisco is so important and so applicable in our day.

One of the most annoying things with javascript is trying to see what is inside of an object.  In python you simply print (‘attributes=%s’%dir(obj)), and in php you simply use var_dump(obj), or if you want to format it into a string, you can use echo “attributes=” . var_export(obj) ;  But with Javascript I really haven’t had an easy way to introspect the attributes of an object.  Until now.

I have been using a great tool for debugging javascript called FireBug, it is a plugin for firefox.  So, firebug has a way to do object introspection via the DOM tab.  When you get an object that you want to analyze simply do something like this in your code (at a global level) var MYOBJECTREFERENCE = new Object();  Now, wherever you have access to that object you want to introspect (in an event handler or whatever), you simply say MYOBJECTREFERENCE.XYZ = obj;  Then, refresh, trigger whatever event it took to generate obj, and then look in firebug’s DOM explorer window for MYOBJECTREFERENCE.XYZ.

YAY!  Now there is an easy way to introspect objects in javascript.  If you know of other ways to do this, please post them for us all to see.

I found another way to do this.  The code is from RefactorMyCode.com .  Mine is a little different because I was getting errors and I had to protect against them a bit… Here you go!

function odump(obj, depth, max) {
 depth = depth || 0;
 max = max || 2;

 if (depth > max)
 return false;

 var indent = "";
 for (var i = 0; i < depth; i++)
 indent += "  ";

 var output = "";
 for (var key in obj){
 // skiplist
 if (key == "domConfig" || key == "selectionStart" || key == "selectionEnd" || key == "schemaTypeInfo") {
 output += "\n" + indent + key + "**: ";
 } else {
 try {
 output += "\n" + indent + key + ": ";
 switch (typeof obj[key]){
 case "object": output += odump(obj[key], depth + 1, max); break;
 case "function": output += "function"; break;
 default: output += obj[key]; break;
 }
 } catch(err) {
 alert("add key=" + key + " to your skiplist because of: err=" + err);
 }
 }
 }
 return output;
}

This is from last week at Solitude.  I have since gotten a new board that is amazing!  I got an Escape from neivasnowboards, it rocks.  I will do a review and pictures of it later.  But for today, here is early season photos from my first trip.  Note, I went yesterday and it was like 50 times better than these shots, so fun in fact that I forgot to pull out my phone and grab photos… Oh well   Headed up tomorrow to get the kids on the run and get them learning, so maybe I will take a few more pix and put them on here.
