Question

所以我得到了这个JSON对象。我想通过nodes中的所有对象进行迭代，但nodes对象不是作为具有[]的数组的对象

如果我知道名称，我可以一个接一个地访问：

var X = Trend.L13

var node = X.nodes["AGENT.OBJECTS.House.SKL04_SK2.L13.Frost.AL01"]

但我如何迭代它们呢？

var Trend = {


L13: {
    dataArchive: "datavalues",
    nodes: {
      "AGENT.OBJECTS.House.SKL04_SK2.L13.Frost.AL01": {
        visible: true,
        axis: "left",
        style: "Line",
        color: "#66AF31",
        linewidth: 1,
        nonstop: true,
        stairs: true,
        configname: "L13",
        address: "AGENT.OBJECTS.House.SKL04_SK2.L13.Frost.AL01",
        text: "Frost"
      },
      "AGENT.OBJECTS.House.SKL04_SK2.L13.TempZul.MT01": {

您可以使用这段代码

    var Nodes = Trend.L13.nodes;
    for(var key in Nodes) {
      if( Nodes.hasOwnProperty(key) ) {
      console.log(Nodes[key]);
      // Use Nodes[key] in this case to access individual objects
      } 
    }
