无法发布图片，如果需要请通知我
感谢您的任何帮助！这样做的目的是能够编辑一张卡上的列表并将其移动到另一张卡上的列表。我还试图使该项目也包括可编辑的时间，可编辑的描述和对象的图片。所有这些都没有显示在列表中，只是标题。如果我需要解释更多，请告诉我。我对此很陌生。
Card Edit:
on preopencard
## Populate the fields
put empty into field "title 2"
put empty into field "description 2"
put the long date into field "date 2"
## Check which task we want to edit
## using the custom property set on this card when we selected a task from the list
put the cTaskID2 of me into tTaskID2
## Get the current details of the task
put taskDetail2(tTaskID2, "title 2") into tTitle2
put taskDetail2(tTaskID2, "description 2") into tDescription2
put taskDetail2(tTaskID2, "completed 2") into tCompleted2
## And display then in the relevant fields
put tTitle2 into field "title 2"

## This tells it which task has been selected so the correct details can be shown
set the cTaskID2 of card "edit 2" to tTaskID2
go to card "edit 2"
end showTaskDetails2
这是Livecode
我不清楚，为什么要在属性中保存那么多数据。数据放入字段后，您可以将其保存在该字段中。当您需要将数据从一张卡上的字段移动到另一张卡上的字段时，可以直接执行此操作。例如，假设您要将卡1的“标题”和“描述”字段的内容复制到卡2的相同字段中。
// this handler is in the card script of card 2
on preOpenCard
put fld "Title" of cd 1 into fld "Title"
put fld "Description" of cd 1 into fld "Description"
end preOpenCard
这就是您所需要的。在这种特殊情况下，不需要自定义属性。
