从对象数组中删除特定属性

Question

  delColumn($event: any, el: any) {
if ($event.target && el > -1) {
  var colId: string = this.receivedData[0].value.columns[el].id;
  var obj = this.receivedData[0];
  obj.values.columns = obj.values.columns.filter(s => s.id != colId);
  obj.values.rows.forEach(s => {
    delete s.Col_1;
    return s;
  });
}

}

现在，我的要求是当我单击“删除列”时，它会进入此方法，并且我想删除与之关联的特定列和行。

提前谢谢你的帮助。

Answer 1

为每个使用过滤器和

obj.values.columns = obj.values.columns.filter(s => s.id != "Col_1");
obj.values.rows.forEach( s => {
   delete s.Col_1;
   return s;
});

  rows=[{Col1:1,Value:1},
        {Col1:1,Value:2},
        {Col1:1,Value:3},
        {Col1:1,Value:4}];

  rowsNew=this.rows.map(x=>{
     return this.objectWithoutKey(x,"Col1");
  })
  objectWithoutKey(object, key){
    const {[key]: deletedKey, ...otherKeys} = object;
    return otherKeys;
  }
  ngOnInit()
  {
     console.log(this.rows);
     console.log(this.rowsNew);
  }
