如何使用jQuery获得鼠标点击按钮?
$('div').bind('click', function(){
alert('clicked');
});
这是由右键和左键点击触发的，有什么方法可以捕捉到鼠标右键点击?如果存在以下内容，我会很高兴:
$('div').bind('rightclick', function(){
alert('right mouse button is pressed');
});

如果你正在寻找“更好的Javascript鼠标事件”，其中允许
离开mousedown 中间mousedown 对mousedown 离开mouseup 中间mouseup 对mouseup 左键点击 中间点击 右击 mousewheel起来 mousewheel下来
看看这个跨浏览器的正常javascript触发上述事件，并消除了头痛的工作。只需将其复制并粘贴到脚本头部，或将其包含在文档<head>中的文件中。然后绑定你的事件，参考下面的代码块，它显示了一个jquery的例子捕捉事件和触发函数分配给他们，虽然这与正常的javascript绑定工作以及。

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 */

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");

case 'right':
if (document.createEvent) {
event = new Event(type+':'+button);
e.target.dispatchEvent(event);
} else {
event = document.createEventObject();
e.target.fireEvent('on'+type+':'+button, event);
}
break;
}
}
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(使用jquery为简单，但以上将跨浏览器工作，并触发相同的事件名称，IE使用在名称之前)
<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)}();
其他回答
编辑:我在jQuery 1.7或以上版本中使用.on()将其更改为动态添加的元素:
$(document).on("contextmenu", ".element", function(e){
alert('Context Menu event has fired!');
return false;
});
演示:jsfiddle.net/Kn9s7/5
[原文开始]这对我来说是有效的:
$('.element').bind("contextmenu",function(e){
alert('Context Menu event has fired!');
return false;
});
以防你有多种解决方案^^
编辑:Tim Down提出了一个很好的观点，它并不总是会是右键单击触发上下文菜单事件，但当上下文菜单键被按下时(这可以说是右键单击的替代)
也有一种方法，不用JQuery!
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.special.rightclick = {
bindType: "contextmenu",
delegateType: "contextmenu"
};
$(document).on("rightclick", "div", function() {
console.log("hello");
return false;
});
使用jquery，你可以使用事件对象类型
jQuery(".element").on("click contextmenu", function(e){
if(e.type == "contextmenu") {
alert("Right click");
}
});
<!DOCTYPE html>

<title>JS Mouse Events - Button Demo</title>

<button id="btn">Click me with any mouse button: left, right, middle, ...</button>
<p id="message"></p>
<script>
let btn = document.querySelector('#btn');
// disable context menu when right-mouse clicked
btn.addEventListener('contextmenu', (e) => {
e.preventDefault();
});
// show the mouse event message
btn.addEventListener('mouseup', (e) => {
let msg = document.querySelector('#message');
switch (e.button) {
case 0:
msg.textContent = 'Left mouse button clicked.';
break;
case 1:
msg.textContent = 'Middle mouse button clicked.';
break;
case 2:
msg.textContent = 'Right mouse button clicked.';
break;
default:
msg.textContent = `Unknown mouse button code: ${event.button}`;
}
});
</script>
</body>
