data
zone.data
You might want to get data back from can-zone, for example if you are using the library to track asynchronous rendering requests. Each zone contains a data object which can be used to store artibitrary values.
var Zone = require("can-zone");
var xhr = new XMLHttpRequest();
xhr.open("GET", "http://example.com");
xhr.onload = function(){
// Save this data for later
Zone.current.data.xhr = xhr.responseText;
};
xhr.send();
