[转]javascript删除数组项目的技巧

1. map + splice 写法

deleteInfo(recycleItem) {
  this.todoInfos.map((item, index) => {
    if(item.id == recycleItem.id) {
      this.todoInfos.splice(index, 1);
    }
  })
}

2. splice + findIndex 写法

deleteInfo(recycleItem) {
  this.todoInfos.splice( this.todoInfos.findIndex( v => v.id === recycleItem.id), 1);
}

3. filter 写法

deleteInfo(recycleItem) {
  this.todoInfos = this.todoInfos.filter( (x) => {
    return x.id != recycleItem.id;
  })
}
