How to print object attributes/values

[laredotornado]

Hi,

I have this alert statement

alert(myObj);

which when executed, alerts "[object Object]", or something similar.
Is there a way I can see a list of attributes and values instead or do
I have to write a custom method for my object?

Thanks, - Dave

Hi,

A rude approach is:

for (myKey in myObj){
alert ("myObj["+myKey +"] = "+myObj[myKey]);
}

(Not tested)

There is a way to see a list of enumerable properties and their values, and
a custom method would generalize this.

Yes there is, in FireFox : alert(myObj.toSource());

javascript:alert({a:1,b:2}.toSource());

It is supported in all Gecko-based UAs because it is a JavaScript[tm]
feature. The Matrix got you!

Aside from the already given answers, my preferred method when using
browser-based javascript, is to use firefox's firebug extension and
call console.debug(myObj);

That will show a show summary in firebug's console/log tab, which you
can click to browse through the object including its properties. Very
handy.
