JSONarea

JSON Validated Textarea. Lightweight and without opinion.

If you are using a HTML <textarea> to allow your users to insert JSON, JSONarea was made just for you. JSONarea prides itself on what it does not do more than what it does do.

does:

• Listens to input events on a textarea and dispatches an update event indiciating whether or not the input is valid JSON.
• allows you to configure the events it listens to
• allows you to extend JSONarea with any number of Objects

doesn't:

• Hit the DOM
• require any third party dependencies

Configuration

Name	Description	Default
events	Array of events to listen to	['change','keyup']
sourceObjects	Optional Array of objects to extend JSONArea with	[]

Usage

// do the deal
var myJSONArea = JSONArea(document.getElementById('json'),{
  sourceObjects:[] // optional array of objects for JSONArea to inherit from
});

// then here's how you use JSONArea's update event
myJSONArea.getElement().addEventListener('update',function(e){
  if(e.detail.isJSON) {
    // do something
  } else {
    // do something else
  }
});
