按属性将对象数组与另一个对象的键进行比较

Question

我想将 data.examples 数组对象 name.value 属性值与 wcObject.notCoveredList 进行比较key，如果密钥匹配，我想将 wcObject的所有匹配值推送到数组，以便在UI中显示。如果密钥不匹配，我希望data.examples数组对象的 name.desc属性值由删除 未涵盖<推送/ em>最后的文字。

    data = {
        examples : [
          {
            name: {
              value:"someOne",
              desc: "some random word not covered"
            },
            type: {
              value:"General",
              desc:"General"
            }
          }, {
            name: {
              value:"secondOne",
              desc: "second on in the queue not covered"
            },
            type: {
              value:"General",
              desc:"General"
            }
          }, {
            name: {
              value:"thirdOne",
              desc: "third one from the last not covered"
            },
            type: {
              value:"General",
              desc:"General"
            }
          }
        ]

      }

 wcObject = {
    notCoveredList : [
      { someOne: "anyone can start " },
      { secondOne: "second One cannot start" },
      { thirdOne: "third One can be allowed" }
    ]
  }

所以，这段代码：

1. 构建过滤器对象。我们抓住了所有的钥匙 data.examples，并将它们设置在单个对象上（使用 一个未定义的值），以便我们可以用一个单独查找这些键 当我们需要过滤时，hasOwnProperty（）调用而不是迭代数组。
2. 将name.desc数组的每个成员映射到其自己的name.value属性或[去除＆＃39;未涵盖＆＃39;] wcNotCoveredKeys = wcObject.notCoveredList.reduce((memo, item) => { // value is empty for all, we only care about keys. memo[Object.keys(item)[0]] = undefined; return memo; }, {}) // having built up our lookup table of those not covered, we continue: forUI = data.examples.map(example => { if (wcNotCoveredKeys.hasOwnProperty(example.name.value)) { return example.name.value; } else { notCoveredString = example.name.desc; cutOutIndex = notCoveredString.indexOf(' not covered'); return notCoveredString.slice(0, cutOutIndex) } }); 财产。

["someOne", "second on in the queue", "thirdOne"]

（更新为整合字符串切片）

为了清楚起见：如果你从wcObject.notCoveredList中删除了第二个项目，那么你输入forUI的输出（给定你提供的示例数据结构/值）将是

@echo off setlocal enableDelayedExpansion FOR /f "skip=1 tokens=5 delims=:," %%I IN (vers.json) DO IF NOT DEFINED ver SET "ver=%%I" set ver=%ver:"=% set ver=%ver: =% echo !ver!
