PushMessageData.json

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The json()method of the PushMessageData interface extracts push message data by parsing it as a JSON string and returning the result.

Syntax

var myData = PushEvent.data.json();

Parameters

None.

Returns

The result of parsing push event data as JSON. This could be anything that can be represented by JSON — an object, an array, a string, a number...

Examples

self.addEventListener('push', function(event) {
  var myData = event.data.json();

  // do something with your data
});
