Trouble connecting JSON elements to HTML using jQuery

Can someone help me troubleshoot this code? I've been struggling to extract elements from this JSON data. Here's what I have so far:

$(document).ready(function() {

$.getJSON('http://free.worldweatheronline.com/feed/weather.ashx?q=Stockholm&format=json&num_of_days=2&key=e8536d3a52101433121710', function(Wdata) {
                $.each(Wdata.data, function() {

                $('<div id="test"></div>').append(

                        this.weather[0].date;

                        ).appendTo('body');

                  });
    });
});

This is how my HTML appears:

<!doctype html>
<html lang="se">
    <head>
        <meta charset="utf-8" />
        <title>Title of This Web Page</title>
        <script src="scripts\jquery-1.8.2.js" type="text/javascript"></script>
        <script src="scripts\js.js" type="text/javascript"></script>
    </head>

    <body>
              <div id="test">
              </div>
    </body>

</html>

Here is a snippet of the JSON data:

{

    "data": {
        "current_condition": [ … ],
        "request": [ … ],
        "weather": [
            {
                "date": "2012-10-17",
                "precipMM": "0.8",
                "tempMaxC": "11",
                "tempMaxF": "51",
                "tempMinC": "8",
                "tempMinF": "46",
                "weatherCode": "119",
                "weatherDesc": [
                    {
                        "value": "Cloudy"
                    }
                ],
                "weatherIconUrl": [
                    {
                        "value": "http://www.worldweatheronline.com/images/wsymbols01_png_64/wsymbol_0003_white_cloud.png"
                    }
                ],
                "winddir16Point": "SW",
                "winddirDegree": "224",
                "winddirection": "SW",
                "windspeedKmph": "27",
                "windspeedMiles": "17"
            },
            { … }
        ]
    }

}

Answer №1

To resolve issues in your code, utilize the JavaScript console and carefully read any errors it provides.

An error occurred: Uncaught SyntaxError: Unexpected token ;

Remember to terminate statements, not expressions. Remove unnecessary semicolons like so: this.weather[0].date;

Once you make that correction, you will encounter:

Error message: XMLHttpRequest cannot load

http://free.worldweatheronline.com/feed/weather.ashx?q=Stockholm&format=json&num_of_days=2&key=e8536d3a52101433121710. Origin http://fiddle.jshell.net
is not allowed by Access-Control-Allow-Origin.

This topic is well-discussed on this site, as seen here: learn more about Access-Control-Allow-Origin

Answer №2

In the case that your request involves a cross domain scenario where the URL is not within your domain, it is advisable to enable the cross-domain flag or consider utilizing JSONP as an alternative method.
