将键值传递给另一个具有不同长度的数组

Question

嗨我有两个包含对象的数组。我试图将title属性的哈希值传递给另一个具有标题键值对的对象，但没有哈希值（它是一个空字符串）。

诀窍是数组未排序且长度不同。

这是我的代码：

var res = [
  [{
      title: "time goes by",
      searchhash: ""
    },
    {
      title: "gta vice city",
      searchhash: ""
    },
    {
      title: "miami beach",
      searchhash: ""
    }
  ],

  [{
      title: "miami beach",
      search_hash: "12456"
    },
    {
      title: "time goes by",
      search_hash: "98765"
    }
  ]

]

for (var i = 0; i < res[0].length; i++) {
  if (res[0][i].searchhash === "") {
    titlePass(res[0][i].title)
    res[0][i].searchhash = function hashPass(p) {
      console.log(p);
      i += 1
    }
  }
}

function titlePass(t) {
  //Here I'm getting the titles (t)
  res[1].forEach((obj) => {
    if (t === obj.title) {
      hashPass(obj["search_hash"])
    }
  })
}

但我得到hashPass不是一个函数。我知道我可以在for循环之外访问hashPass函数的那些值，但是我希望在for循环中传递这些值以将其分配给searchhash属性...

你是说这个吗？

var res = [
  [{
      title: "time goes by",
      searchhash: ""
    },
    {
      title: "gta vice city",
      searchhash: ""
    },
    {
      title: "miami beach",
      searchhash: ""
    }
  ],

  [{
      title: "miami beach",
      search_hash: "12456"
    },
    {
      title: "time goes by",
      search_hash: "98765"
    }
  ]

]


for (var i = 0; i < res[0].length; i++) {
  var res0 = res[0][i];
  if (res0.searchhash === "") {
    var title = res0.title;
    for (var j=0;j<res[1].length;j++) {
      var res1 = res[1][j];
      if (res1.title == title) res0.searchhash=res1.search_hash;
    }
  }
}
console.log(res)

您可以尝试以下代码。

var res = [
  [{
      title: "time goes by",
      searchhash: ""
    },
    {
      title: "gta vice city",
      searchhash: ""
    },
    {
      title: "miami beach",
      searchhash: ""
    }
  ],

  [{
      title: "miami beach",
      search_hash: "12456"
    },
    {
      title: "time goes by",
      search_hash: "98765"
    }
  ]

]

for (var i = 0; i < res[0].length; i++) {
  if (res[0][i].searchhash === "") {
    titlePass(res[0][i]);
  }
}

function titlePass(o) {
  res[1].forEach((obj) => {
    if (o.title === obj.title) {
      o["searchhash"] = obj["search_hash"];
    }
  })
}
