Please **don't** fire click actions during the `mousedown` event. It ignores the rest of the event pipeline and goes against current user expectations and design practices.

## Problem

Here's a look at the normal order of events that fire for each click type:



    $(document).on("mousedown mouseup click focus blur",function(e) {
      console.log("{" + e.which + ":" + e.type + "}"); 
    });    

[![Click Events][1]][1]

Typically, we handle the very last [`click`][2] event because it signifies the users final intent to proceed with the current action.

> The `click` event is fired when a pointing device button (*usually a mouse's primary button*) is **pressed and released** on a *single element*.

Unfortunately, middle mouse presses do not fire such an event (probably because doing so would force developers listening to the click event to distinguish between multiple possible invocations).  But if we want to wire up actions against the middle click, we should follow the same UX expectations.

## Solution 

We'll listen for `mousedown` events and immediately attach a one time use handler for `mouseup` events.  If the middle key was pressed and if the elements match, we'll [trigger][3] our own [custom event][4] with type `middleclick`, which we'll [seed from the original event][5].

```js
$(document).on("mousedown", function (e1) {
  $(document).one("mouseup", function (e2) {
    if (e1.which == 2 && e1.target == e2.target) {
      var e3 = $.event.fix(e2);
      e3.type = "middleclick";
      $(e2.target).trigger(e3)
    }
  });
});
```

That'll help separate out determining *if* the middle button was clicked with how we we want to handle it in that case, so we can setup a listener for our custom event type like this:


```js
$(document).on("middleclick", function (e) {
	console.log("{" + e.target.nodeName.toLowerCase() + ":" + e.type + "}"); 
});
```

### Working Demo in [jsFiddle][6] and Stack Snippets:





    $(document).on("mousedown", function (e1) {
      $(document).one("mouseup", function (e2) {
        if (e1.which == 2 && e1.target == e2.target) {
        	var e3 = $.event.fix(e2);
          e3.type = "middleclick";
          $(e2.target).trigger(e3)
        }
      });
    });

    $(document).on("middleclick", function (e) {
      console.log("{" + e.target.nodeName.toLowerCase() + ":" + e.type + "}"); 
    });

    $(document).on("mousedown mouseup click focus blur",function(e) {
      console.log("{" + e.which + ":" + e.type + "}"); 
    });

I have a list with a tags to play some mp3 files onclick. It is working fine when binding on the 'click' event with jQuery:

    $oo.data({'__mp3play':true,'wapiHandle':h+0,'wapiIndex':o.ajaxPlayList[h].length})
    		   .bind( 'click', function()
    			{ var wh = $j(this).data('wapiHandle');
    			  if( typeof o.regObjects[wh] == 'object' && o.regObjects[wh].play(this.href))
    			   { return false; }
    			});

When clicking the left mouse button:
It disables default handling when my flash plugin is loaded otherwise it will be opened normally.

BUT:
When I use the scrollbutton of the mouse and click on it, the click event will not fired and the link opens normally.

I have tried to use mousedown or mouseup events but doesn't help, the link always opens normally with the side effect that the music starts playing also with the flash player.

Also `preventDefault()` does not work at all.

Can somebody tell me how to detect the middle mouse button click (scroll button click)?

Thank you for your comments.

PS: I have already tried other solutions about the 'middle button' available on this site.

Tested in all kind of browsers with the same result. 

EDIT:
This also does not work, the link will be opened normally when using the middle mouse button. When using the left mouse button, nothing happen. 

    $oo.bind( 'mousedown click mouseup', function(e)
    { e.preventDefault(); e.stopPropagation(); return false; });




Detect middle button click (scroll button) with jQuery

I would highly recommend using semantic markup to describe the content of your page.  This helps make your content accessible and work as expected across a variety of devices and use cases that you might not be capturing.

So use an anchor tag `<a>` to link to `\login.php`, and then you can choose to style that similar to a button if you'd like.





    body {
        padding: 15px;
        background: #211f1f;
    }

    a.login-button {
        color: salmon;
        border: 1px solid salmon;
        padding: 10px 15px;
        border-radius: 20px;
        text-decoration: none;
    }



    <a href="login.php" class="login-button">Login</a>

I'm trying to make a simple button.  But instead of `<button>`, I'm using `<div>` and `<p>`, but the result will show up as only border, and the text won't show up over the border.

Am I doing something wrong?

    .Something4 p2 {
