What is the JavaScript equivalent of var_dump or print_r in PHP?

Question

Hi, I would like to see the structure of object in JavaScript (for debugging). Is there anything similar to var_dump in PHP? Thanks

Answer 1

Install Firebug for Firefox and do this:

console.log(myvar);

Then you will get a nicely mapped out interface of the object/whatever in the console.

Check out the console documentation for more details.

Answer 3

Firebug.

Then, in your javascript:

var blah = {something: 'hi', another: 'noway'};
console.debug("Here is blah: %o", blah);

Now you can look at the console, click on the statement and see what is inside blah
