在兩個列表之間移動可編輯項目？

Question

不能發佈圖片的又一讓我知道，如果需要的話

感謝您的幫助！這樣做的目的是能夠編輯一張卡上的列表並將其移動到另一張卡上的列表中。我也試圖讓物品移動也包含可編輯的時間，可編輯的描述和對象的圖片。所有這些都不在名單上顯示，只是標題。如果我需要解釋更多，請告訴我。我對此很新穎。

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" 
    put tDescription2 into field "description 2" 

    ## Set the label of the completed button to allow you to toggle the state 
    if tCompleted2 then 
     set the label of button "completed 2" to "mark as incomplete" 
    else 
     set the label of button "completed 2" to "mark as complete" 
    end if 
end preopencard 

on closeCard 
    ## Check which task we want to update 
    ## using the custom property set on this card when we selected a task from the list 
    put the cTaskID2 of me into tTaskID2 

    if tTaskID2 is not empty then 
     ## Update the task data in the cTaskData custom property of the stack 
     updateTask2 tTaskID2, field "title 2", field "description 2" 

     ## Save the task data out to file, ensures our file always refelects the current state 
    saveTaskData 
    end if

List on card: 

on mouseUp 
    ## Work out which task has been selected 
    ## The taskID corresponds to the line number in the list 
    put word 2 of the clickline into tTaskID2 
    showTaskDetails2 tTaskID2

on showTaskDetails2 tTaskID2 
    ## Set a custom property on the task editor card 
    ## 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

爲什麼你保存性能如此多的數據目前尚不清楚給我。一旦數據進入現場，您可以將其保留在那裏。當您需要將數據從一張卡上的字段移動到另一張卡上的字段時，可以直接進行。例如，假設您想要的領域「標題」和卡1的「說明」的內容複製到相同的字段上卡2

// 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 

這是你所需要的。在這種情況下不需要定製屬性。
