How do I dump JavaScript vars in IE8?

Question

I have an object I need to examine in IE8. I tried the developer tools and console.log, their Firebug equivalent. However, when I output the object to the log:

console.log("Element: ", element);
console.log(element);

I only get the string

LOG: Element: [object Object]

instead of a clickable, examinable dump.

Is it possible to dump an object to the Log and examine its members, like in Firebug?

I can't use a homemade dump() function because the element I want to examine is so huge the browser will crash on me.

Answer 1

One suggestion is to use Firebug-Lite: It wraps console obj and you can see the result in IE like in most of the firebug console. Hope this help.

Answer 2

A bit chunky but it works for DOM objects:

 console.log( testNode.outerHTML.replace(testNode.innerHTML,"") ); 

Answer 3

I know this is a REALLY old question, but I was looking for an answer to this just now. If it's not an absolute requirement to use the IE console (which isn't very good, IMO), then you might consider using Firebug Lite (http://getfirebug.com/firebuglite). It's not a perfect solution, and you may not want to push that script out to your production environment, and it's not as full featured as Firebug, but it's pretty good in a pinch when you have to much around with a low-end browser like IE.

Answer 4

A bit off topic (as it won't work for DOM elements) but I've found it handy to use the JSON.stringify(object) to get a JSON string for the object which is pretty readable.

Dump it into an existing HMTL-Element

I noticed IE 11 is stripping off console lines after 1027 chars :-/ When I had a large object to dump (12,000 chars) I dumped it into an existing DIV- oder TextArea-Element, from where I could copy the content.

var str = JSON.stringify(myObject);
$('#existing-element').text(str); // jQuery or
document.querySelector("#existing-element").innerHTML = str; // native JavaScript
