javascript - How use Mithril's m.request to load data from a server? -


i want store blocks of json file array. here current code, in controller (ctrl) :

var ctrl = this; var id = (location.href).replace(/.*\//g, ''); //use m.route() ? ctrl.list = [];  m.request({method: "get", url: "/data/"+id}).then(function(blocks){     blocks.map(function(block) {         ctrl.list.push(block);     }); });  console.log(ctrl.list); //result : empty array. why ?

m.request asynchronous operation: needs make request server, wait server answer, load contents, , give response — why implements then: give callback can things data when arrives.

but console.log happening after make request: response isn't ready yet. depends upon server data needs invoked inside then callback function.
