javascript - Right click stop propagation - Stack Overflow

admin2025-04-26 0

How do I stop the propagation for right click events in javascript, so parent elements do not detect them at all? When I click the link in the following html, left clicks are not detected, but right clicks are detected by the document element as 'click' events instead of 'contextmenu' events. I've tried to attach event listeners to mousedown, contextmenu, but to no success.

[EDIT] Changing the code to contextmenu works on chrome but not firefox (v23.0.1), this is probably a firefox bug.

<!DOCTYPE html>
<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script type="application/javascript;version=1.8">

function log(s){
    document.getElementById('log').innerHTML+=s+'<br/>';
}

window.onload=function(){
    document.addEventListener('click',function(e){
        log('click detected');
    },false);

    let link=document.querySelector('a#link');
    //click only cares about left clicks
    link.addEventListener('click',function(e){
        e.stopPropagation();
        return false;
    },false);
};

</script>
</head>

<body>

<a id="link" href="javascript:void(0);">Link</a>

<div id="log"></div>

</body>
</html>

Are you looking to disable right click on link? – defau1t Commented Sep 7, 2013 at 18:28
No, I want the context menu to still show up, but the event should not propagate to any parent element. – simonzack Commented Sep 7, 2013 at 18:29
What event are you trying to stop propagating, contextmenu? – Pavlo Commented Sep 7, 2013 at 18:41
Any click (left or right click) event. – simonzack Commented Sep 7, 2013 at 18:42
I've just run into the same problem, trying to prevent right-clicks from propagating. Firefox versions 25, 29, and 31 all have this behaviour where right-clicks produce a click event on the document which can't be stopped by stopPropagation(). – Emma Leis Commented Jul 23, 2014 at 6:09

The 'right click' event is called the 'contextmenu' event.

http://www.quirksmode/dom/events/contextmenu.html

Example:

<!DOCTYPE html>
<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script>

function log(s){
        document.getElementById('log').innerHTML+=s+'<br/>';
}

window.onload=function(){
        document.addEventListener('click',function(e){
                log('click detected');
        },false);

        document.addEventListener('contextmenu', function(e){
                log('right-click detected');
        }, false);

        var link=document.querySelector('a#link');

        link.addEventListener('click',function(e){
                e.stopPropagation();
                return false;
        },false);

        link.addEventListener('contextmenu',function(e){
                e.stopPropagation();
                return false;
        },false);
};

</script>
</head>

<body>

<a id="link" href="javascript:void(0);">Link</a>

<div id="log"></div>

</body>
</html>

Chrome won't execute script tags, including a version , for some reason, so i replaced let with var...

Stopping the propagation of a contextmenu event triggered from a#Link to document works fine for me, in Chrome and Firefeox, here is the example i used.

Edit

the contextmenu events are detected by the document element as click events instead.

In this case you can use a mousedown event, and add the condition event.which === 3

I updated the example, and added an example on JSBin

<!DOCTYPE html>
<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

</head>
<body>

<a id="link" href="javascript:void(0);">Link</a> 
<div id="log"></div>

<script type="application/javascript">
window.onload = function () {
  var link = document.querySelector('a#link');

  function log(s) {
      document.getElementById('log').innerHTML += s + '<br/>';
  }

  document.addEventListener('mousedown', function (e) {
    if (e.which === 3) {
      var src = e.target || e.srcElement;
      log((src.nodeName === 'A' ? 'bubbled' : 'direct') + ' contextmenu on document detected');
    }
  }, false);

  link.addEventListener("mousedown", propagate);

  function propagate(e) {
    if (e.which === 3) {
      log("contextmenu on link, propagating");
      link.removeEventListener("mousedown", propagate);
      link.addEventListener("mousedown", nopropagate);
    }
  }

  function nopropagate(e) {
    if (e.which === 3) {
      log("contextmenu on link, nopropagating");
      e.stopPropagation();
    }
  }
}
</script>
</body>
</html>

Now rightclicking in the following order gives us these outputs.

rightclick on document
rightclick on link (propagates on first click)
rightclick on link (doesn't propagate)

Screenshots are from Firefox 20.0
