我有js数组，如下所示：
var names = [{name:"high",id:1},{name:"high",id:2},
{name:"low",id:1}, {name:"low",id:2},{name:"medium",id:1},{name:"medium",id:2}];
我需要像这样创建另一个数组。
var newArr=[{name:high,items:[1,2]},{name:low,items:[1,2]},{name:medium,items:[1,2]}];
请建议我该怎么做。
var obj = {};
_.each(names, function (e) {
var o = obj[e.name];
if (o) {
o.items.push(e.id);
} else {
o = {name: e.name, items: [e.id]};
}
obj[e.name] = o;
});
var result = _.map(obj, function (e) {return e;});
var obj = {};
for (var i = 0; i < names.length; i++) {
var e = names[i];
var o = obj[e.name];
if (o) {
o.items.push(e.id);
} else {
o = {name: e.name, items: [e.id]};
}
obj[e.name] = o;
}
var result = [];
for (var k in obj) {
if (obj.hasOwnProperty(k)) {
result.push(obj[k]);
}
};
