JSON for OpenLaszlo

JSON for OpenLaszlo is an implementation of JSON for the OpenLaszlo platform. It is an Open Source package available under the MIT License.

Requirements

Any ECMAScript interpreter or compiler. (There are other implementations available for Javascript and ActionScript — the sole benefit of this implementation is that it’s compatible with OpenLaszlo.)

The *.lzx files are OpenLaszlo source files, and require the OpenLaszlo SDK.

Installation

Download the zip file from http://osteele.com/sources/openlaszlo/json/openlaszlo-json-1.0.zip.

Usage

  JSON.stringify(123) // => '123'
  JSON.parse('123') // => 123

See the header of json.js for additional usage information.

Examples

Here is a complete OpenLaszlo program that prints a JSON string, and a parsed object, to the debugger:

  <canvas debug="true">
    <script src="json.js">
    <script>
      Debug.write(JSON.stringify([1729, "argos", {a: 1}]));
      Debug.write(JSON.parse('[1729, "argos", {"a": 1}]'));
    </script>
  </canvas>

For an example of using JSON with AJAX to parse response text, see json-example.lzx. This example is also running on the blog page for this project.
