Time for action – getting JSON data

Now let's do the same thing as we did in the previous section, except that we will get the data from a file containing JSON formatted data rather than XML. The concept is the same, except that what we get back from the Ajax call is a JavaScript object rather than an XML document. You can find the code for this example in Chapter 8/example8.2.

First let's define our JSON file, which we will name weather.json, and put it in the data folder:

{
    "location": {
        "city":"Your City"
    }
    ,"current_observation": {
        "weather":"Clear",
        "temperature_string":"38.3 F (3.5 C)",
        "wind_string":"From the WSW at 1.0 MPH Gusting to 5.0 MPH",
        "feelslike_string":"38 F (3 C)",
        "relative_humidity":"71%",
        "icon_url":"images/nt_clear.gif"
    ...
