Javascript in Applescript

Question

I'm trying to run a little Javascript inside an AppleScrip, but to no joy, and can't find the problem.

If I run the Javascript from the console in Chrome, it works perfectly, but when I insert it into the AppleScript, it doesn't do anything.

Here is my code:

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

I have to use Javascript because the link I am trying to click and download from is dynamic, so I cannot just give the applescript a static address.

I don't know, maybe there is a better way to do this?

Any help would be appreciated, thanks!

Did you try to test the javascript call with some simpler action such as console.log(...) ? — Ilya

The AppleScript's do javascript command do nothing on an window, you must specify a tab of an window or a document

Like this

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

Or this

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
