您正在将JavaScript添加到整个Row中，而不是添加到单个ImageButton中.

You''re adding the javascript to the entire Row, not to the single ImageButton.

e.Row.Attributes.Add

因此，我认为，javascript函数将为整个行中的每个按钮和链接触发.
尝试将ADD_img强制转换为ImageButton(而不是字符串).然后

So, I think, the javascript function will trigger for every button and link in the entire row.
Try to cast ADD_img to a ImageButton (and not to a String). Then

ADD_img.Attributes.Add("OnClick", "javascript:return openph(" & Edid_img & ")")

抱歉，我使用C#编写代码，但应该相同.
让我知道！

Sorry, I code in C# but should be the same.
Let me know!

If e.Row.RowType = DataControlRowType.DataRow Then
                
                Dim ADD_img As imagebutton = DirectCast(e.Row.FindControl("Add"), ImageButton)
                
 dim result as string
                

  result= Add_img.commandname.tostring & "." & Session.Item("ID")
    Add_img.attributes.Add("OnClick", "javascript:return openph(" & result & ")")           
end if     
 
                   
                End If
