Trigger javascript with a hotkey

[JolinM]

Hi, I am trying to trigger the instapaperizing action from Alfred.

I seted up a hotkey, followed by either a run script action or an open page in browser, with this code inside, but nothing seams to work… any clue?

 

Thanks!

 

 

javascript:function%20iptxt()%7Bvar%20d%3Ddocument%3Btry%7Bif(!d.body)throw(0)%3Bwindow.location%3D%27http://www.instapaper.com/text%3Fu%3D%27%2BencodeURIComponent(d.location.href)%3B%7Dcatch(e)%7Balert(%27Please%20wait%20until%20the%20page%20has%20loaded.%27)%3B%7D%7Diptxt()%3Bvoid(0)

I'm assuming that you are just trying to "open" this? I would assume that OSX probably doesn't know how to handle that because javascript exists in the browser and not OS-wide. You can still do it though.

 

Try this instead.

tell application "Safari" to do JavaScript "javascript:function iptxt(){var d=document;try{if(!d.body)throw(0);window.location='http://www.instapaper.com/text?u='+encodeURIComponent(d.location.href);}catch(e){alert('Please wait until the page has loaded.');}}iptxt();void(0)" in the current tab of the front window

 

That triggers the javascript to run in the current tab of the front window in Safari (assuming that's what your using). We may have to tweak it a little bit if you aren't using Safari but I would think it would still be possible in the other browsers.

Woohoo, thanks for the help, it works and I figured out how to do it with Chrome!

Awesome, happy to help. If you haven't already, be sure to share it in the Share Your Workflows area.

The link expired. How can I trigger a javascript on Alfred to run it on Safari at the same page?

 

javascript:(function()%7B(function%20()%20%7Bvar%20i%2C%20elements%20%3D%20document.querySelectorAll('body%20*')%3Bfor%20(i%20%3D%200%3B%20i%20%3C%20elements.length%3B%20i%2B%2B)%20%7Bif%20(getComputedStyle(elements%5Bi%5D).position%20%3D%3D%3D%20'fixed')%20%7Belements%5Bi%5D.parentNode.removeChild(elements%5Bi%5D)%3B%7D%7D%7D)()%7D)()

As described above:

O try to follow it but, I'm sorry, I couldn't get success. Step-by-step I tap to add a new one > Template > Essentials > Keyword to Script.
In fact, I will add a hotkey to run on Safari "Control+Option+Command+K" in any website but it's not working.

We can't possibly tell you what's wrong from such a description.

 

Please upload your workflow somewhere (Dropbox?) and post a link, so we can see for ourselves what the workflow is doing.

[Saez]

Take a look. I thought could be so simple but I know it's wrong. https://www.dropbox.com/s/xbx3pr8rze3zb8i/Kill Sticky.alfredworkflow?dl=0

You have it set to the wrong language. That’s AppleScript, so you need Language = /usr/bin/osascript (AS)

 

You also got the AppleScript wrong. It’s tell application "Safari" to do JavaScript "<JS code goes here>" in the current tab of the front window (like in the post I linked you to.)

 

Finally, there’s actually no need to use javascript: and URL-encode the JavaScript. You’re telling the browser to execute code, not open a URL.

 

I'd provide you with a working version, but I'm afraid I don't understand what the JS is supposed to do or where.

[Saez]

I really thank you and I'm keep trying to understand how it works in fact.
Look at this site: https://alisdair.mcdiarmid.org/kill-sticky-headers/
That's what this JS do. So, today I have it in my favorite bar and just a tap works fine and I remember Alfred can run JS with a hotkey so I tried again and again and again hahaha (... and still trying)

[deanishe]

You can paste that code as-is into your AppleScript:

 

tell application "Safari" to do JavaScript "(function () { 
  var i, elements = document.querySelectorAll('body *');

  for (i = 0; i < elements.length; i++) {
    if (getComputedStyle(elements[i]).position === 'fixed') {
      elements[i].parentNode.removeChild(elements[i]);
    }
  }
})();" in the current tab of the front window

 

A slightly shorter version that does the same thing:

 

tell application "Safari" to do JavaScript "(function() {document.querySelectorAll('body *').forEach(el => { if (getComputedStyle(el).position === 'fixed') el.remove(); }) })();" in the current tab of the front window

I tried and it's not working on Safari, it works there?
I think now it's right, isn't it? (btw, I didn't paid attention on the language before)

Forget it friend! I found the error on the log
