Question

这个程序是用于将工厂的JSON数据发送到localhost，但我得到了错误。当选择订单时，订单将被发送到另一个订单。当我单击选择按钮时，控制台中发生错误。

主要HTML页面

Private Sub Paddline_Click()
Dim i As Long
    Dim rng3rows As Range
    Dim rng3CellsColumn As Range
    For i = Range("A" & Rows.Count).End(xlUp).Row To 1 Step -1
        If Range("A" & i).Value = "~P~" Then
            Set rng3rows = Range(Rows(i), Rows(i + 2))  'using a range to include the 3 rows you want to copy over
            rng3rows.Copy
            Rows(i).Insert
            Set rng3CellsColumn = Range(Cells(i, 1), Cells(i + 2, 1))  'using a range to clear the the cells in the column A
            rng3CellsColumn.ClearContents
            Rows(i).Select
        End If
    Next
    Application.CutCopyMode = False

并且控制器意味着将列表从工厂发送到本地存储..

我很感激你的回答

Answer 1

似乎JSON.parse($window.localStorage.getItem("orderedfoods"))返回的内容不是数组。也许本地存储中没有任何东西？当您在localstorage中处理不存在的项时，它将返回null。您可以尝试修复它：

var orderedfood = JSON.parse($window.localStorage.getItem("orderedfoods"))||[];

Answer 2

您的orderedfood数组对象为空。您可以取消注释控制台日志并确认。为避免该错误，您可能需要检查null并为orderedfood分配一个空数组，如下所示：

 var orderedfood = JSON.parse($window.localStorage.getItem("orderedfoods"));
 console.log(orderedfood);
orderedfood = orderedfood || [];
