以
Array#map
方法回调中的数组形式返回元素。var phases = mainData.places.map(function(e){ return [e.name , 50]; });
var arr = { "id": "100", "name": "the name", "places": [{ "id": "23", "name": "first place", "startDate": "2015-01-30 15:01:00", "endDate": "2015-01-30 17:01:00" }, { "id": "54", "name": "second place", "startDate": "2015-01-31 17:01:00", "endDate": "2015-02-01 17:01:00" }, { "id": "400", "name": "third place", "startDate": "2015-02-01 17:01:00", "endDate": "2015-02-05 17:01:00" }] } var phases = arr.places.map(function(e) { return [e.name, 50]; }); console.log(phases);
Return the element as an array inside the
Array#map
method callback.var phases = mainData.places.map(function(e){ return [e.name , 50]; });
var arr = { "id": "100", "name": "the name", "places": [{ "id": "23", "name": "first place", "startDate": "2015-01-30 15:01:00", "endDate": "2015-01-30 17:01:00" }, { "id": "54", "name": "second place", "startDate": "2015-01-31 17:01:00", "endDate": "2015-02-01 17:01:00" }, { "id": "400", "name": "third place", "startDate": "2015-02-01 17:01:00", "endDate": "2015-02-05 17:01:00" }] } var phases = arr.places.map(function(e) { return [e.name, 50]; }); console.log(phases);
