這是我的數據數組，我想通過鍵刪除CSH4870543427var object = {}; object ={            0:{id:'CSH4870543427',actual_selling_price: "7.27"},            1:{id:'CSH4002543427',actual_selling_price: "7.30"}         };var dataArray = [];$.each(object,function(index, entry){    dataArray[entry.id] = entry;});如何使用 key 刪除數據？這是我的代碼 var item = "CSH4870543427";   var index = dataArray.indexOf(item);   dataArray.splice(index, 1);上面的代碼不起作用
