How to Send JSON Data Directly with jQuery's $.ajax?

How to Transmit JSON Directly via $.ajax Rather Than a Query String

When working with jQuery's $.ajax method, you may encounter an issue where it automatically converts JSON data into a query string. To prevent this conversion and transmit actual JSON, follow these simple steps:

  1. Serialize Your Object to JSON: Use the JSON.stringify method to convert your object into a JSON string. This ensures that your data remains in JSON format.
  2. Set Content Type: Specify the Content-Type header as "application/json" in your $.ajax request. This informs the server that the data being sent is in JSON format.

Here's an updated code snippet that implements both steps:

<code class="javascript">$.ajax({
    url: url,
    type: "POST",
    data: JSON.stringify(data),
    contentType: "application/json",
    complete: callback
});</code>

Additional Notes:

  • JSON.stringify is natively available in browsers supporting JavaScript 1.7 / ECMAScript 5 or later.
  • If you need support for legacy browsers, you can utilize the json2 library.
  • By following these steps, you can ensure that your JSON data is sent directly to the server without any unintended conversions.
