我是javascript的新手.我想知道装载是如何工作的.假设在我的html页面中我有一个可见性被设置为隐藏的图像.我有一个按钮,点击时使用javascript将图像的可见性属性设置为visbile.加载页面时,图像会加载,或者在单击按钮时加载图像.
同样我想知道display值设置为none的display属性.
提前致谢.

我已经创建了一个Excel的加载项,其确定的名称ActiveSheet和 ActiveWorkbook.我使用的代码如下.当我运行加载项时,它会在消息框"变量设置"后显示上述错误.但是当我在宏中运行它时工作正常.我不明白加载项发生了什么.任何人都可以帮我这个吗？

    Dim book As String, sht As String, i As Integer, j As Integer
    Dim att(1 To 4) As String, att_col(1 To 4) As Integer

    MsgBox ("variables set")

    book = ActiveWorkbook.Name
    sht = ActiveSheet.Name
    MsgBox ("names set")

    Set bk = Workbooks.Add
    With bk
        .Title = "MissingValues"
        .SaveAs Filename:="MissingValues.xls"
    End With

    Set sht1 = bk.Sheets.Add
    sht1.Name = "EndOne"
    Set sht2 = bk.Sheets.Add …
