jQuery doesn't support postmessage event?

Question

When I use jQuery event listener to handle message event, like below:

$(window).on(\'message\', function(e) {
    var data = e.data; // data = undefined
});
         


        

Answer 1

jQuery might be preprocessing the event's data property, and this operation may not properly support the message event (yet).

Try using the originalEvent property to fetch your data:

$(window).on("message", function(e) {
    var data = e.originalEvent.data;  // Should work.
});
