Question

I am trying to learn url persistence, and a friend told me to study this block of code:

$(document).ready(function(){
var objects = {};
var DEFAULT_LOCATION = "diameter";


$("#animateObjects").hide();


var urlDimension = location.hash.replace("#","");
if (urlDimension.length == 0) {
    // location.hash = "#" + DEFAULT_LOCATION;
    urlDimension = DEFAULT_LOCATION;
    $("#"+DEFAULT_LOCATION).addClass("active");
    clog("started with no dimension, defaulted to " + DEFAULT_LOCATION);
}
else {
    $("#"+urlDimension).toggleClass("active");
    clog("started with dimension: " + urlDimension);
}

What does the clog() method accomplish?

Full code is here.

Answer 1

I’d bet its a wrapper around console.log to cater for IE not being able to handle it.

something like this:

function clog(message) {
    try {
        console.log('message');
    } 
    catch (ex) {}
}
