Retrieving Data from a Django Response: A Guide to Parsing JSON

Here is an example of my response:

[{"0": "[email protected]"}, {"1": "[email protected]"}, {"2": "[email protected]"}, {"3": "[email protected]}, {"4": "[email protected]"}, {"5": "[email protected]"}, {"6": "[email protected]"}]

I am attempting to interpret this using the following HTML:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">

    $(document).ready(function(){


        document.write('Getting JSON response...');
        $.getJSON(<my django url>,
            function(data) {
            alert("receiving"+data["0"]);
            });
    });

</script>

</head>


<body>
</body>
</html>

However, I do not see any alert box with the data displayed, only the "Getting JSON response..." message appears on the screen.

This is my return statement:

return HttpResponse( simplejson.dumps(result) , content_type='application/json')

Answer №1

The issue lies within the JSON format that you provided, which cannot be parsed or evaluated correctly. A typical JSON object looks like this:

[
    {"attributeName1":"value1", "attributeName2":"value2"},
    {"attributeName1":"value3", "attributeName2":"value4"}
]

However, in your JSON example, you are using attributeName1 as 0. This is equivalent to assigning a variable name as 0, such as

define 0 = <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="442f042f6a272b29">[email protected]</a>
. Such naming convention is not allowed. It would be better to change it to something like id0.

Answer №2

Appreciate the assistance everyone.

The method of using data [0][0] was effective.

When iterating through the loop until encountering an undefined value in data[i][j], I implemented:

data[i][i.toString()]; which proved to be successful.
