[javascript] Object Dump JavaScript

Is there a 3rd party add-on/application or some way to perform object map dumping in script debugger for a JavaScript object?

Here is the situation... I have a method being called twice, and during each time something is different. I'm not sure what is different, but something is. So, if I could dump all the properties of window (or at least window.document) into a text editor, I could compare the state between the two calls with a simple file diff. Thoughts?

If you're on Chrome, Firefox or IE10 + why not extend the console and use

(function() {
    console.dump = function(object) {
        if (window.JSON && window.JSON.stringify)
            console.log(JSON.stringify(object));
        else
            console.log(object);
    };
})();

for a concise, cross-browser solution.

For Chrome/Chromium

console.log(myObj)

or it's equivalent

console.debug(myObj)

In Chrome, click the 3 dots and click More tools and click developer. On the console, type console.dir(yourObject).Click this link to view an example image

console.log("my object: %o", myObj)

Otherwise you'll end up with a string representation sometimes displaying:

[object Object]

or some such.

for better readability you can convert the object to a json string as below:

console.log(obj, JSON.stringify(obj));

Just use:

console.dir(object);

you will get a nice clickable object representation. Works in Chrome and Firefox

Using console.log(object) will throw your object to the Javascript console, but that's not always what you want. Using JSON.stringify(object) will return most stuff to be stored in a variable, for example to send it to a textarea input and submit the content back to the server.

function mydump(arr,level) {
    var dumped_text = "";
    if(!level) level = 0;

    var level_padding = "";
    for(var j=0;j<level+1;j++) level_padding += "    ";

    if(typeof(arr) == 'object') {  
        for(var item in arr) {
            var value = arr[item];

            if(typeof(value) == 'object') { 
                dumped_text += level_padding + "'" + item + "' ...\n";
                dumped_text += mydump(value,level+1);
            } else {
                dumped_text += level_padding + "'" + item + "' => \"" + value + "\"\n";
            }
        }
    } else { 
        dumped_text = "===>"+arr+"<===("+typeof(arr)+")";
    }
    return dumped_text;
}
