Applescript和"开始于"运算符

Question

有没有办法检查(在AppleScript中)列表(或html文本块)是否有starts with任意数量的值.

示例(检查单个值)

if {foobar starts with "<p>"} then
    -- do something awesome here
end if

除了我想传递多个值来检查<p>或<h1>或<em>.

提前致谢.

Answer 1

on startswith(txt, l)
    repeat with v in l
        if txt starts with v then return true
    end repeat
    false
end startswith

startswith("abc", {"a", "d", "e"}) -- true

Answer 2

如果你想保持 AppleScript 的“英语”风格，虽然比上面的例子长，你可以这样做：

if {foobar starts with "hello" or foobar starts with "goodbye"} then

一个完整的例子是：

set foobar to "hello dude"
if {foobar starts with "hello" or foobar starts with "goodbye"} then
    display dialog "found"
end if

即使您更改，这也是正确的：

set foobar to "hello dude"

到：

set foobar to "goodbye dude"
