用对象的属性查找数组里的对象

[lovelmh13]

[{"id":1101154,"name":"asd"}, {"id":1101067,"name":"abc"}] -> 找出id=1101067的对象 -> {"id":1101067,"name":"abc"}

function objFindInArray(array, key, val) {
  const res = array.find((obj) => {
    return obj[key] === val
  })
  return res
}

一个find就搞定，千万别遍历数组的每一项，又去遍历每一项的key：

      for (const chapter of this.chapterOptions) {
        Object.keys(chapter).find((item) => {
          if (chapter[item] === this.jump.chapterId) {
            this.currChapter = chapter
          }
        })
      }

这简直就是脱裤子放屁，没错 就是曾经的我...
