Jika Anda mencari "Acara Mouse Javascript Lebih Baik" yang memungkinkan
- meninggalkan tikus
- tengah musim gugur

Lihat javascript normal peramban silang ini yang memicu peristiwa di atas, dan menghilangkan pekerjaan sakit kepala. Cukup salin dan tempel ke bagian atas skrip Anda, atau sertakan dalam file di dalam <head>
dokumen Anda. Kemudian ikat acara Anda, lihat blok kode berikut di bawah ini yang menunjukkan contoh jquery menangkap peristiwa dan menjalankan fungsi yang ditugaskan untuk mereka, meskipun ini bekerja dengan javascript mengikat normal juga.

/**
Better Javascript Mouse Events
Author: Casey Childers

(function(){
// use addEvent cross-browser shim: https://gist.github.com/dciccale/5394590/
var addEvent = function(a,b,c){try{a.addEventListener(b,c,!1)}catch(d){a.attachEvent('on'+b,c)}};
/* This function detects what mouse button was used, left, right, middle, or middle scroll either direction */

var button = '';
if (e.type == 'mousedown' || e.type == 'click' || e.type == 'contextmenu' || e.type == 'mouseup') {
if (e.which == null) {

} else {
button = (e.which < 2) ? "left" : ((e.which == 2) ? "middle" : "right");

Contoh Acara Klik Mouse yang Lebih Baik (menggunakan jquery untuk kesederhanaan, tetapi di atas akan bekerja lintas browser dan mem-api nama acara yang sama, IE menggunakan sebelum nama-nama)
<div id="Test"></div>
<script type="text/javascript">
$('#Test').on('mouseup',function(e){$(this).append(e.type+'<br />');})
.on('mouseup:left',function(e){$(this).append(e.type+'<br />');})
.on('mouseup:middle',function(e){$(this).append(e.type+'<br />');})
.on('mouseup:right',function(e){$(this).append(e.type+'<br />');})
.on('click',function(e){$(this).append(e.type+'<br />');})
.on('click:left',function(e){$(this).append(e.type+'<br />');})
.on('click:middle',function(e){$(this).append(e.type+'<br />');})
.on('click:right',function(e){$(this).append(e.type+'<br />');})
.on('mousedown',function(e){$(this).html('').append(e.type+'<br />');})
.on('mousedown:left',function(e){$(this).append(e.type+'<br />');})
.on('mousedown:middle',function(e){$(this).append(e.type+'<br />');})
.on('mousedown:right',function(e){$(this).append(e.type+'<br />');})
.on('mousewheel',function(e){$(this).append(e.type+'<br />');})
.on('mousewheel:up',function(e){$(this).append(e.type+'<br />');})
.on('mousewheel:down',function(e){$(this).append(e.type+'<br />');})
;
</script>
Dan bagi mereka yang membutuhkan versi yang diperkecil ...
!function(){function e(e){e=window.event||e;var t="";if("mousedown"==e.type||"click"==e.type||"contextmenu"==e.type||"mouseup"==e.type)t=null==e.which?e.button<2?"left":4==e.button?"middle":"right":e.which<2?"left":2==e.which?"middle":"right";else{var n=e.detail?-120*e.detail:e.wheelDelta;switch(n){case 120:case 240:case 360:t="up";break;case-120:case-240:case-360:t="down"}}var c=e.type;switch("contextmenu"==e.type&&(c="click"),"DOMMouseScroll"==e.type&&(c="mousewheel"),t){case"contextmenu":case"left":case"middle":case"up":case"down":case"right":document.createEvent?(event=new Event(c+":"+t),e.target.dispatchEvent(event)):(event=document.createEventObject(),e.target.fireEvent("on"+c+":"+t,event))}}var t=function(e,t,n){try{e.addEventListener(t,n,!1)}catch(c){e.attachEvent("on"+t,n)}};t(window,"mousedown",e),t(window,"mouseup",e),t(window,"click",e),t(window,"contextmenu",e);var n=/Firefox/i.test(navigator.userAgent)?"DOMMouseScroll":"mousewheel";t(window,n,e)}();
