Applescript 中的 Javascript

Question

我正在尝试在 AppleScrip 中运行一些 Javascript，但没有成功，也找不到问题所在。

如果我从 Chrome 的控制台运行 Javascript，它运行完美，但是当我将它插入 AppleScript 时，它什么也做不了。

这是我的代码:

set alertReply to display alert "New Build" message "A new build is now available!" buttons ["Cancel", "Show"] default button 2 giving up after 5
if button returned of alertReply is equal to "Show" then
tell application "Safari"
    activate
    tell window 1 
        set current tab to make new tab with properties {URL:"https://bamboo...."}
        delay 5
        do JavaScript "clickArtifactsAndWait(); function clickArtifactsAndWait () { var menu_items = document.getElementsByClassName('menu-item'); var id_prefix = 'artifacts:'; for (var i = 0, length = menu_items.length; i < length; i++) {   if (menu_items[i].children[0].id.substr(0, id_prefix.length) == id_prefix) {     menu_items[i].children[0].click();   } } setTimeout(downloadMacBuild, 3000);  }  function downloadMacBuild() { var links = document.getElementsByTagName('a') for (var i = 0, length = links.length; i < length; i++) {   if (links[i].innerHTML == 'builds-mac') {     links[i].click();   } }  }"

    end tell
end tell
end if

我必须使用 Javascript，因为我尝试点击和下载的链接是动态的，所以我不能只给 applescript 一个静态地址。

我不知道，也许有更好的方法来做到这一点？

任何帮助将不胜感激，谢谢!

AppleScript 的do javascript 命令在窗口上不执行任何操作，您必须指定窗口的选项卡 或文档

像这样

tell application "Safari"
    tell window 1
        set current tab to make new tab with properties {URL:"...."}
        delay 5
        do JavaScript "some command" in current tab
    end tell
end tell

或者这个

tell application "Safari"
    tell window 1
        set current tab to make new tab with properties {URL:"...."}
        delay 5
    end tell
    do JavaScript "some command" in document 1 -- document 1 is the current tab of the front window
end tell
