Question

我是一个相当特殊的Applecripter，并且已经写了很长时间的脚本。我目前正在创建的应用程序涉及使用“数据库事件”应用程序。我试图通过使用子程序设置字段的值。显然，我“不能继续set_duration”，我不知道会出现什么问题。目前的源代码如下。

property first_run : true
on run
if first_run then
display dialog "THIS APPLICATION IS DESIGNED TO CLEAN UP THE FOLDER CONTAINING IT." & return & return & "After a certain number of days that you set, every item in that folder that has not been used for that duration will automatically be moved to a folder named \"Unused Items\"." with icon 1 buttons {"Cancel", "OK"} default button 2
set first_run to false
end if
tell application "Database Events"
set quit delay to 0
try
get database "Folder Cleanup Wizard"
on error
make new database with properties {name:"Folder Cleanup Wizard"}
tell database "Folder Cleanup Wizard"
make new record with properties {name:"Duration"}
tell record "Duration" to make new field with properties {name:"Days", value:set_duration()} --> UNKNOWN ERROR
end tell
end try
end tell
end run

on set_duration()
try
set duration to the text returned of (display dialog "Enter the minimum duration period (in days) that files and folders can remain inactive before they are moved to the \"Unused Items\" folder." default answer "" with title "Set Duration") as integer
if the duration is less than 0 then
display alert "Invalid Duration" message "Error: The duration cannot be a negative number." buttons {"OK"} default button 1
set_duration()
end if
on error
display alert "Invalid Duration" message "Error: \"" & (duration as string) & "\" is not a valid duration time." buttons {"OK"} default button 1
set_duration()
end try
end set_duration

Answer 1

问题是AppleScript将set_duration视为来自database "Folder Cleanup Wizard"或来自application "Database Events"的术语，这要归功于tell块。（在tell块之外，只需普通set_duration()即可。）为了解决这个问题，您需要使用my set_duration()，它告诉AppleScript查看当前脚本中的函数。所以，在这种情况下，你有

...
tell record "Duration" to ¬
  make new field with properties {name:"Days", value:my set_duration()}
...

Answer 2

我认为这是因为Applescript在set_duration生活的地方感到困惑

做这样的事情

tell me to set value_to_set to set_duration()
tell record "Duration" to make new field with properties {name:"Days", value:value_to_set}

我认为这对你有用

Applescript子程序有问题
