在选择器中使用“or”将AppleScript转换为JXA

Question

我想将这个工作 AppleScript 转换为 JS:

tell application "Music"
    repeat with theTrack in (every track whose name is "Baby" or name is "aBby")
        tell theTrack
            set name to do shell script ¬
                "echo " & quoted form of (name & "") & ¬
                " | sed 's/^\\([aB]\\)\\([aB]\\)/\\2\\1/'"
        end tell
    end repeat
end tell

但是我选择曲目的代码不起作用：

const music = Application("Music");

const tracks = music.tracks.whose({ _or: [ {name: "Baby"}, {name: "aBby"} ] })();

tracks.forEach(track => {
    track.name = track.name().replace(/^([aB])([aB])/, '$2$1');
});

app = Application("Music")
    app.tracks.whose({_or: [{_match: [ObjectSpecifier().name, "Baby"]}, {_match: [ObjectSpecifier().name, "aBby"]}]})()
Result:
Error -1700: Can't convert types.

当我摆脱

_or

、

...tracks.whose({ name: "Baby" })

时，它就起作用了。

如何将 AppleScript 转换为 JavaScript for Automation 脚本？

Answer 1

您遇到的问题似乎是由于 JavaScript for Automation (JXA) API 与 who 和其他对象说明符等属性交互的方式造成的。这与 AppleScript 处理它们的方式略有不同。

const music = Application("Music");

// Retrieve the tracks whose name is "Baby"
const tracks = music.tracks.whose({ name: "Baby" })();

// Iterate through the matching tracks and rename them
tracks.forEach(track => {
    // Get the current name of the track
    const currentName = track.name();

    // Perform the shell script operation using JavaScript's `doShellScript` function
    const newName = Application.currentApplication().doShellScript(`echo "${currentName}" | sed 's/^\\(.\\)\\(.\\)/\\2\\1/'`);

    // Set the new name to the track
    track.name = newName;
});
