Question

我有一个选择列表。无论您在列表中做出什么选择，都应确定下一个列表中可用的选择。我目前正在接收

错误“无法获得\“ \”的项目1。“来自“”

项目1的编号-1728

似乎第一个列表中的set变量没有馈入If Else If语句。

    set currentSupport to "" -- initialize the variable
    set supportList to choose from list {"A", "B"} with prompt "Source:" default items {"A"}
    set currentSupport to result

    set currentPR to "" -- initialize the variable
    if currentSupport is "A" then
        set misrouteList to choose from list {"1", "2", "3", "4"} with title "Prepared Responses" with prompt "Reason:"
        set currentPR to result
    else if currentSupport is "B" then
        set misrouteList to choose from list {"5", "6", "7", "8", "9", "10"} with title "Prepared Responses" with prompt "Reason:"
        set currentPR to result
    end if


    set supportChoice to item 1 of currentSupport
    set prChoice to item 1 of currentPR

如果用户按下choose from list或项目的列表（即使未启用false，则

Cancel返回with multiple selections。

您必须在{strong> {}表达式之前

if - else

或没有冗余代码

set currentSupport to "" -- initialize the variable
set supportList to choose from list {"A", "B"} with prompt "Source:" default items {"A"}
if supportList is false then return
set currentSupport to item 1 of supportList

set currentPR to "" -- initialize the variable
if currentSupport is "A" then
    set misrouteList to choose from list {"1", "2", "3", "4"} with title "Prepared Responses" with prompt "Reason:"
    if misrouteList is false then return
    set currentPR to item 1 of misrouteList
else if currentSupport is "B" then
    set misrouteList to choose from list {"5", "6", "7", "8", "9", "10"} with title "Prepared Responses" with prompt "Reason:"
    if misrouteList is false then return
    set currentPR to item 1 of misrouteList
end if


set supportChoice to currentSupport
set prChoice to currentPR

或保留选择内容作为列表并检查set supportList to choose from list {"A", "B"} with prompt "Source:" default items {"A"} if supportList is false then return set currentSupport to item 1 of supportList if currentSupport is "A" then set responseList to {"1", "2", "3", "4"} else -- there is only A or B set responseList to {"5", "6", "7", "8", "9", "10"} end if set misrouteList to choose from list responseList with title "Prepared Responses" with prompt "Reason:" if misrouteList is false then return set currentPR to item 1 of misrouteList set supportChoice to currentSupport set prChoice to currentPR

{"A"}
