javascript - 合并以多种方式返回的多个数组/对象

Question

我创建了一个选择，在更改时从对象中提取“节点”和“链接”。更改值后，我必须重新创建具有相同结构jsonServit但结果新内容的对象。

在下面的代码中，我有 3 个 console.log。我必须将这 3 个返回混合到一个对象中。如果我选择我得到的选择的第一个值：

• 第一个控制台日志（SelectedNodeArray）：

//should be grouped with "nodes"
{id: "Anzelma", group: 4}

• 第二个控制台日志（LinksArray）：

//should be grouped with "links"
0: {source: "Anzelma", target: "Eponine", value: 2}
1: {source: "Anzelma", target: "Thenardier", value: 2}
2: {source: "Anzelma", target: "Mme.Thenardier", value: 1}

• for 循环内的第三个控制台日志（linkedNodesArray）：

//should be grouped with "nodes"
0: {id: "Eponine", group: 4}
0: {id: "Thenardier", group: 4}
0: {id: "Mme.Thenardier", group: 4}

我怎样才能将所有 3 个返回组合成这样的对象？

{"nodes":[
    {id: "Anzelma", group: 4},
    {id: "Eponine", group: 4},
    {id: "Thenardier", group: 4},
    {id: "Mme.Thenardier", group: 4}
],
"links":[
    {source: "Anzelma", target: "Eponine", value: 2},
    {source: "Anzelma", target: "Thenardier", value: 2},
    {source: "Anzelma", target: "Mme.Thenardier", value: 1}
]}

谢谢你。

Answer 1

好的，如果我理解正确，过程如下：

1. 生成唯一字符名称列表
2. 使用列表填充选择
3. 用户选择这些名称之一
4. （在这里您缺少检查用户选择的名称是否也存在于您的列表中，因为用户可以生成任何东西）
5. 标识选择名称对应的节点 -> SelectedNodeArray
6. 相关链接标识-> LinksArray
7. 标识链接另一侧对应的节点 -> linkedNodesArray
8. 将所有 3 组合成一个与您最初得到的具有相同结构的对象。

代码

var namesArray = [];

$.each(jsonServit.nodes, function(index) {
  var name = jsonServit.nodes[index].id;
  if ($.inArray(name, namesArray) == -1) {
    namesArray.push(name);
  }
});

namesArray.sort();

$.each(namesArray, function(index) {
  $("#SelectName").append('<option value="' + namesArray[index] + '">' + namesArray[index] + '</option>');
});

// result variable
var result = {};

$("#SelectName").change(function() {
  // Move the var declaration inside the each as they are temp variables
  var LinksArray = [];

  var selectedName = this.value;

  SelectedNodeArray = $.grep(jsonServit.nodes, function(node, index) {
    return node.id == selectedName;
  });
  LinksArray = $.grep(jsonServit.links, function(link, index) {
    return link.source == selectedName;
  });

  console.log(SelectedNodeArray);
  console.log(LinksArray);

  var linkedNodesArray = [].concat(SelectedNodeArray);

  for (var i = 0; i < LinksArray.length; i++) {
    linkedNodesArray = linkedNodesArray.concat($.grep(jsonServit.nodes, function(link, index) {
      return link.id == LinksArray[i].target;
    }));
  }
  console.log(linkedNodesArray);
  result.nodes = linkedNodesArray;
  result.links = LinksArray;

  console.log(result);
});
