Use alert(JSON.stringify(theObject));
JSON.stringify returns "[object Object]" instead of the contents of the object

Here I'm creating a JavaScript object and converting it to a JSON string, but JSON.stringify
returns "[object Object]"
in this case, instead of displaying the contents of the object. How can I work around this problem, so that the JSON string actually contains the contents of the object?
var theObject = {name:{firstName:"Mark", lastName:"Bob"}};
alert(JSON.stringify(theObject.toString())); //this alerts "[object Object]"

theObject.toString()
The .toString()
method is culprit. Remove it; and the fiddle shall work: http://jsfiddle.net/XX2sB/1/
JSON.stringify returns "[object Object]" in this case
That is because you are calling toString()
on the object before serializing it:
JSON.stringify(theObject.toString()) /* <-- here */
Remove the toString()
call and it should work fine:
alert( JSON.stringify( theObject ) );
Use
var theObject = {name:{firstName:"Mark", lastName:"Bob"}};
alert(JSON.stringify(theObject));
