Question

我想将每个日期转换为类型列表中的类型，例如 {string，integer，text，...} ，如下所示：

set ret to {}
set aStringList to {"abc","123","def","456"}
set typeList to {string,integer,string,integer}
repeat with i from 1 to (count aStringList)
    set theStr to item i of aStringList
    set end of ret to theStr as (item i of typeList)
end repeat
log ret

是否可以实施？

您无法在运行时使用动态强制，在编译时会对强制进行评估。

你必须做那样的事情：

set ret to {}
set aStringList to {"abc", "123", "def", "456"}
set typeList to {string, integer, string, integer}
repeat with i from 1 to (count aStringList)
    set theStr to item i of aStringList
    set classIndex to item i of typeList
    if classIndex = string then
        set end of ret to theStr as string
    else if classIndex = integer then
        set end of ret to theStr as integer
    end if
end repeat
log ret
