jQuery data() object to JSON string

I'm trying convert jQuery Data object to JSON string.

I tried:

$.data(plant).toJSON()

JSON.stringify($.data(plant))

but doesn't seems to be working. It showing undefined in firebug.开发者_StackOverflow中文版(edited)

This is what I got when I log $.data(plant):

Object { residential="Condo", location="Garden", watering="Weekly"}

Can anyone tell me how to convert this jQuery data() object to JSON string?

Using JSON.stringify() should work just fine:
