我的原始对象如下（对象名是runOverview）。我想删除粗体字段版本、输入、加载、产品和project_name。
{"版本"："1"，"输入"：[{"名称"："输入1"，"值"："1，827 "}，{"姓名"："输入2"，"值"："310 "}]，"加载"：[{"名称"："负载1"，"值"："440 "}，{"姓名"："负载2"，"值"："220 "}，{"姓名"："负载3"，"值"："46 "}]、"产品"：[{"名称"："产品1"，"价值"："15，000 "}，{"姓名"："产品3"、"价值"："4.8 "}]、"项目名称"："测试"}
我想更改runOverview对象，如下所示（预期输出）。

{{
      "name": "input1",
      "value": "1,827"
    },
    {
      "name": "input2",
      "value": "310"
    },
    {
      "name": "loads1",
      "value": "440"
    },
    {
      "name": "loads2",
      "value": "220"
    },
    {
      "name": "loads3",
      "value": "46"
    },
    {
      "name": "products1",
      "value": "15,000"
    },
    {
      "name": "products3",
      "value": "4.8"
    }}

我已经尝试了以下方法

const overviewDetails = computed(() => {
  const overviewArr = [];
    for ( var newdata in runOverview.value) {
      overviewArr.push(newdata)
    }
  return overviewArr
});

- 请帮助我创建仅具有必需属性的新对象数组**

这是非常强大的它将合并任何属性的值是一个数组.我相信这是你想要的：

// </script><script type="module">
import { ref, computed } from "https://unpkg.com/vue@3.2.47/dist/vue.runtime.esm-browser.js"

const runOverview = ref({ "version": "1", "inputs": [ { "name": "input1", "value": "1,827" }, { "name": "input2", "value": "310" } ], "loads": [ { "name": "loads1", "value": "440" }, { "name": "loads2", "value": "220" }, { "name": "loads3", "value": "46" } ], "products": [ { "name": "products1", "value": "15,000" }, { "name": "products3", "value": "4.8" } ], "project_name": "Test" })

const overviewDetails = computed(() => {
  return Object.values(runOverview.value).reduce((r, item) => {
    if (Array.isArray(item)) r.push(...item)

    return r
  }, [])
})

console.log(overviewDetails.value)

可以使用reduce和map方法。请尝试以下操作：

<script type="module">
import { ref, computed } from "https://unpkg.com/vue@3.2.47/dist/vue.runtime.esm-browser.js"

const runOverview = ref({version:"1",inputs:[{name:"input1",value:"1,827"},{name:"input2",value:"310"},],loads:[{name:"loads1",value:"440"},{name:"loads2",value:"220"},{name:"loads3",value:"46"},],products:[{name:"products1",value:"15,000"},{name:"products3",value:"4.8"},],project_name:"Test"});

 const overviewDetails = computed(() =>
  ["inputs", "loads", "products"].reduce(
    (acc, key) =>
      acc.concat(
        runOverview.value[key].map((item) => ({
          name: item.name,
          value: item.value,
        }))
      ),
    []
  )
);
console.log(overviewDetails.value)

</script>

const arr = []
Object.values(runOverview).forEach(item => {
        if(Array.isArray(item)) {
            arr.push(...item)
        }
    })
console.log(arr)
