Json data contains date and time format
You can't read property names with those special characters in them. They need to be quoted:
data.city.forecast["2012-09-10"]["06:00"].w
Here's a related question:
any string can be a property name ... some properties can only be accessed using the bracket syntax.
Try with :
data.city.forecast['2012-09-10']['06:00'].w
Another problem is $("#")
. The selector seems to be wrong. Which element are you targeting ?
