Question

我有一个像这样的数据

var data = [
{name: "name1",age:100,gender: m ,someotherfiled: ""},
{name: "name2",age:101 ,gender: f,someotherfiled: ""}
]

我想只选择两个像这样的字段

[
    {name: "name1",age:100 },
    {name: "name2",age:101}
    ]

如何处理crossfilter？

Answer 1

你不会用Crossfilter做到这一点。最简单的选择可能是使用Array.map创建一个只包含所需字段的新数组：

var data = [
  {name: "name1",age:100,gender: m ,someotherfiled: ""},
  {name: "name2",age:101 ,gender: f,someotherfiled: ""}
];

var newData = data.map(function(d) { return { name: d.name, age: d.age }; });

选择特定列crossfilter
