反应本机阵列更新 [英] React Native Array Updates

问题描述

我有两个对象数组，它们具有匹配的属性(ID和名称).

I have two arrays of objects which have properties that match (id & name).

var result1 = [[
      { title: "Option 1", enable: false },
      { title: "Option 2", enable: false },
      { title: "Option 3", enable: false },
      { title: "Option 4", enable: false },
      { title: "Option 5", enable: false }
    ]
;

var result2 = [
    { title: "Option 3", enable: false },
    { title: "Option 4", enable: false },
];

推荐答案

result1.map(item => {
  const isChecked = result2.some(({ title }) => title === item.title);
  return {
    ...item,
    checked: isChecked
  }
});
