This jQuery snippet converts a JSON string to an array of objects and iterates through them, outputting the key-value pairs. The second snippet shows how to convert the array back to a JSON string using stringify
. However, the provided data.stringify
is incorrect; it should be JSON.stringify(data)
.
var data = JQUERY4U.DASHBOARD.data['widgets']; data = $.parseJSON(data); // Or JSON.parse(data) for modern browsers $.each(data, function (i, v) { console.log(i, v); });
To convert the array back to a JSON string:
$('#columns').html(JSON.stringify(data)); // Corrected stringify method
The FAQ section covers various aspects of JSON conversion across different programming languages. Here's a summarized version focusing on clarity and conciseness:
