Object Dump JavaScript
JavascriptJavascript Problem Overview
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?
Javascript Solutions
Solution 1 - Javascript
console.log("my object: %o", myObj)
Otherwise you'll end up with a string representation sometimes displaying:
[object Object]
or some such.
Solution 2 - Javascript
Firebug + console.log(myObjectInstance)
Solution 3 - Javascript
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;
}
Solution 4 - Javascript
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.
Solution 5 - Javascript
Just use:
console.dir(object);
you will get a nice clickable object representation. Works in Chrome and Firefox
Solution 6 - Javascript
for better readability you can convert the object to a json string as below:
console.log(obj, JSON.stringify(obj));
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify
Solution 7 - Javascript
For Chrome/Chromium
console.log(myObj)
or it's equivalent
console.debug(myObj)
Solution 8 - Javascript
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.
Solution 9 - Javascript
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
