How to Capture the Right-Click Event in JavaScript

How can I capture the right-click event in JavaScript?

Use the oncontextmenu event.

Here's an example:

<div oncontextmenu="javascript:alert('success!');return false;">
    Lorem Ipsum
</div>

And using event listeners (credit to rampion from a comment in 2011):

el.addEventListener('contextmenu', function(ev) {
    ev.preventDefault();
    alert('success!');
    return false;
}, false);

Don't forget to return false, otherwise the standard context menu will still pop up.

If you are going to use a function you've written rather than javascript:alert("Success!"), remember to return false in BOTH the function AND the oncontextmenu attribute.

How to capture right click on a specify element in javascript?

You can use the contextmenu event:

<div oncontextmenu="javascript:alert('Right Click Performed!');return false;">
    Right click on me!
</div>

And then add a listener:

el.addEventListener('contextmenu', function(ev) {
    ev.preventDefault();
    alert('Right Click Performed!');
    return false;
}, false);

Is right click a Javascript event?

As others have mentioned, the right mouse button can be detected through the usual mouse events (mousedown, mouseup, click). However, if you're looking for a firing event when the right-click menu is brought up, you're looking in the wrong place. The right-click/context menu is also accessible via the keyboard (shift+F10 or context menu key on Windows and some Linux). In this situation, the event that you're looking for is oncontextmenu:

window.oncontextmenu = function ()
{
    showCustomMenu();
    return false;     // cancel default menu
}

As for the mouse events themselves, browsers set a property to the event object that is accessible from the event handling function:

document.body.onclick = function (e) {
    var isRightMB;
    e = e || window.event;

    if ("which" in e)  // Gecko (Firefox), WebKit (Safari/Chrome) & Opera
        isRightMB = e.which == 3; 
    else if ("button" in e)  // IE, Opera 
        isRightMB = e.button == 2; 

    alert("Right mouse button " + (isRightMB ? "" : " was not") + "clicked!");
}

How do I get a right click event in my web app

Not sure what "javascript contextmenu" meant, but this should do the job:

(Run snippet and right-click black box)

let testEl = document.getElementById('test');testEl.addEventListener('contextmenu', function(e) {  if(e && e.preventDefault) e.preventDefault();  alert("Right click!");});

#test {  width: 100px;  height: 100px;  background: black;}

<div id="test"></div>

Capture Right Click on HTML DIV

Take a look at this: Javascript - event properties. Value for right mouse button is 2, although also note that it recommends using mousedown or mouseup events rather than click.

Here is a sample from the page showing right click detection:

function doSomething(e) {
    var rightclick;
    if (!e) var e = window.event;
    if (e.which) rightclick = (e.which == 3);
    else if (e.button) rightclick = (e.button == 2);
    alert('Rightclick: ' + rightclick); // true or false
}

Contextmenu right click event

Use $(e.target) for jquery object representing clicked element. Otherwise just use e.target for plain old javascript dom element.

In your case, to alert the column text, try this code:

$(function() {

  var $contextMenu = $("#contextMenu");

  $("body").on("contextmenu", "table tr", function(e) {
    $contextMenu.css({
      display: "block",
      left: e.pageX,
      top: e.pageY
    });
    alert($(e.target).text());
    return false;
  });

  $contextMenu.on("click", "a", function() {
     $contextMenu.hide();
  });

});
