从jQuery版本1.1.3开始, event.which 正常化 event.keyCode event.charCode 因此,您不必担心浏览器兼容性问题。 Documentation on event.which

事件,哪个 将分别为鼠标左键、中键和右键指定1、2或3,因此:

$('#element').mousedown(function(event) {
    switch (event.which) {
        case 1:
            alert('Left Mouse button pressed.');
            break;
        case 2:
            alert('Middle Mouse button pressed.');
            break;
        case 3:
            alert('Right Mouse button pressed.');
            break;
        default:
            alert('You have a strange Mouse!');
    }
});

:我将其更改为适用于使用 .on() 在jQuery 1.7或更高版本中:

$(document).on("contextmenu", ".element", function(e){
   alert('Context Menu event has fired!');
   return false;
});

演示: jsfiddle.net/Kn9s7/5

$('.element').bind("contextmenu",function(e){
   alert('Context Menu event has fired!');
   return false;
});

以防您陷入多种解决方案^^

当前位置Tim Down提出了一个很好的观点,那就是它并不总是会成为 right-click contextmenu 事件,但在按下上下文菜单键时也是如此(这可以说是对 )

您可以通过检查鼠标键来轻松判断按下了哪个鼠标键 which 鼠标事件上事件对象的属性:

/*
  1 = Left   mouse button
  2 = Centre mouse button
  3 = Right  mouse button
*/

$([selector]).mousedown(function(e) {
    if (e.which === 3) {
        /* Right mouse button was clicked! */
    }
});

你也可以 bind 到 contextmenu return false :

$('selector').bind('contextmenu', function(e){
    e.preventDefault();
    //code
    return false;
});

http://jsfiddle.net/maniator/WS9S2/

或者,您可以制作一个快速插件,该插件也可以执行相同的操作:

(function( $ ) {
  $.fn.rightClick = function(method) {

    $(this).bind('contextmenu rightclick', function(e){
        e.preventDefault();
        method();
        return false;
    });

  };
})( jQuery );

演示: http://jsfiddle.net/maniator/WS9S2/2/

使用 .on(...)

$(document).on("contextmenu", "selector", function(e){
    e.preventDefault();
    //code
    return false;
});  //does not have to use `document`, it could be any container element.

$("#element").live('click', function(e) { if( (!$.browser.msie && e.button == 0) || ($.browser.msie && e.button == 1) ) { alert("Left Button"); } else if(e.button == 2){ alert("Right Button"); } });

更新内容的当前状态:

var $log = $("div.log"); $("div.target").on("mousedown", function() { $log.text("Which: " + event.which); if (event.which === 1) { $(this).removeClass("right middle").addClass("left"); } else if (event.which === 2) { $(this).removeClass("left right").addClass("middle"); } else if (event.which === 3) { $(this).removeClass("left middle").addClass("right"); } });

div.target { border: 1px solid blue; height: 100px; width: 100px; } div.target.left { background-color: #0faf3d; } div.target.right { background-color: #f093df; } div.target.middle { background-color: #00afd3; } div.log { text-align: left; color: #f00; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="target"></div> <div class="log"></div>

event.button .

事件按钮 这些代码与W3C使用的代码不同。W3C只考虑3种情况:

event.button === 1
单击鼠标右键- event.button === 3
单击鼠标中键- event.button === 2

然而,在较旧的Internet Explorer中,Microsoft正在为按下的按钮翻转一点,共有8种情况:

未单击任何按钮- event.button === 0
点击左键- event.button==1 或001
单击右键- event.button==2 或010
单击左侧和右侧按钮- 或011
点击中间按钮- event.button === 4 还是100
event.button === 5 或101
单击中键和右键- event.button === 6 或110
所有3个按钮都被单击- event.button === 7 或111

尽管理论上它应该是这样工作的,但没有一个Internet Explorer支持同时按下两个或三个按钮的情况。我之所以提到它,是因为W3C标准甚至在理论上都不能支持这一点。

在我看来,稍微修改一下Villageidiot的答案会更干净:

$('#element').bind('click', function(e) {
  if (e.button == 2) {
    alert("Right click");
  }
  else {
    alert("Some other click");
  }
}

e.which 属性,分别为左键、中键和右键单击返回1、2、3。所以你也可以用 if (e.which == 3) { alert("right click"); }

另见:问题的答案 "Triggering onclick event using middle click"

event.which === 1 确保左键单击(使用jQuery时)。

但您还应该考虑修改器关键点: 控制键 转移 中高音

var isSimpleClick = function (event) {
  return !(
    event.which !== 1 || // not a left click
    event.metaKey ||     // "open link in new tab" (mac)
    event.ctrlKey ||     // "open link in new tab" (windows/linux)
    event.shiftKey ||    // "open link in new window"
    event.altKey         // "save link as"
  );
};

$('a').on('click', function (event) {
  if (isSimpleClick(event)) {
    event.preventDefault();
    // do something...
  }
});

还有一种方法,不用JQuery就可以做到!

看看这个:

document.addEventListener("mousedown", function(evt) {
    switch(evt.buttons) {
      case 1: // left mouse
      case 2: // right mouse
      case 3: // middle mouse <- I didn't tested that, I just got a touchpad
    }
});

event.which 在里面 香草JS 有棱角的 当前位置 不赞成 所以我更喜欢使用 event.buttons 相反

用这种方法和 (穆斯敦) 活动:

单击鼠标左键按 与1关联
与2关联
滚动按钮按下 与4关联

和事件将返回相同的数字,但是 0 相反

如果您正在寻找“更好的Javascript鼠标事件”,它允许

左鼠标向下
鼠标右键向下
左鼠标
中鼠标
右滑鼠
左键单击
中击
右击
鼠标滚轮向上
鼠标滚轮放下

看看这个跨浏览器的普通javascript,它触发了上述事件,并消除了令人头痛的工作。只需将其复制并粘贴到脚本的头部,或将其包含在 <head>

如果您对它的工作感兴趣,请查看JSFIDLE: https://jsfiddle.net/BNefn/

/**
   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 */
    function GetMouseButton(e) {
        e = window.event || e; // Normalize event variable

        var button = '';
        if (e.type == 'mousedown' || e.type == 'click' || e.type == 'contextmenu' || e.type == 'mouseup') {
            if (e.which == null) {
                button = (e.button < 2) ? "left" : ((e.button == 4) ? "middle" : "right");
            } else {
                button = (e.which < 2) ? "left" : ((e.which == 2) ? "middle" : "right");
            }
        } else {
            var direction = e.detail ? e.detail * (-120) : e.wheelDelta;

                case 240:
                case 360:
                    button = "up";
                break;
                case -120:
                case -240:
                case -360:

                break;
            }
        }

        var type = e.type
        if(e.type == 'contextmenu') {type = "click";}
        if(e.type == 'DOMMouseScroll') {type = "mousewheel";}

        switch(button) {
            case 'contextmenu':
            case 'left':
            case 'middle':

                  e.target.dispatchEvent(event);
                } else {
                  event = document.createEventObject();
                  e.target.fireEvent('on'+type+':'+button, event);

    addEvent(window, 'mousedown', GetMouseButton);
    addEvent(window, 'mouseup', GetMouseButton);
    addEvent(window, 'click', GetMouseButton);
    addEvent(window, 'contextmenu', GetMouseButton);

    /* One of FireFox's browser versions doesn't recognize mousewheel, we account for that in this line */
    var MouseWheelEvent = (/Firefox/i.test(navigator.userAgent)) ? "DOMMouseScroll" : "mousewheel";
    addEvent(window, MouseWheelEvent, GetMouseButton);
})();

更好的鼠标点击事件示例(为了简单起见,使用jquery,但上面的内容将跨浏览器工作并触发相同的事件名称,即在名称之前使用on)

<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>

对于那些需要缩小版本的人。。。

!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)}();

使用jquery,您可以使用 event object type

jQuery(".element").on("click contextmenu", function(e){
   if(e.type == "contextmenu") {
       alert("Right click");
   }
});

上面问 关于所有鼠标单击事件类型。

添加此脚本,使其应用于整个页面:

var onMousedown = function (e) {
     if (e.which === 1) {/* Left Mouse Click */}
     else if (e.which === 2) {/* Middle Mouse Click */}
     else if (e.which === 3) {/* Right Mouse Click */}
};
clickArea.addEventListener("mousedown", onMousedown);
