javascript - mustache 模板中的嵌套键

Question

我有以下数据结构:

var data = {
  labels: { name: "Name" },
  data: {
    name: "Layer 1",
    children: [
      {
        name: "Layer 1-1",
        children: [
          { name: "Layer 1-1-1" },
          { name: "Layer 1-1-2" }
        ]
      },
      {
        name: "Layer 1-2",
        children: [
          { name: "Layer 1-2-1" },
          { name: "Layer 1-2-2" }
        ]
      },
      { name: "Layer 1-3" }
    ]
  }
};

正如您所看到的，每一层都可以有自己的子层。在此 fiddle 中，您可以看到，子项被渲染多次: https://jsfiddle.net/kaljak/9xuLpnxp/

我需要更改什么才能使子项仅渲染一次？

Answer 1

您有一对多 {{#children}} 标签，您应该将上面的标签更改为 {{#data}}
