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');
});

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)

switch (e.button) {
case 0:
msg.textContent = 'Left mouse button clicked.';

case 1:
msg.textContent = 'Middle mouse button clicked.';

msg.textContent = 'Right mouse button clicked.';
break;
default:
msg.textContent = `Unknown mouse button code: ${event.button}`;

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
}
});
在我看来，稍微改编一下thevillagediot的答案会更简洁:
$('#element').bind('click', function(e) {
if (e.button == 2) {
alert("Right click");
}
else {
alert("Some other click");
}
}
编辑:JQuery提供了一个e.t it属性，在左、中、右单击时分别返回1、2、3。所以你也可以使用if (e.which == 3) {alert("right click");｝
请参见:“使用中点击触发onclick事件”的回答
通过查看鼠标事件的事件对象的属性，你可以很容易地知道按下了哪个鼠标按钮:
/*
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! */
}
});
$(document).ready(function () {
var resizing = false;
var frame = $("#frame");
var origHeightFrame = frame.height();
var origwidthFrame = frame.width();
var origPosYGrip = $("#frame-grip").offset().top;
var origPosXGrip = $("#frame-grip").offset().left;
var gripHeight = $("#frame-grip").height();
var gripWidth = $("#frame-grip").width();
$("#frame-grip").mouseup(function (e) {
resizing = false;
});
$("#frame-grip").mousedown(function (e) {
resizing = true;
});
document.onmousemove = getMousepoints;
var mousex = 0, mousey = 0, scrollTop = 0, scrollLeft = 0;
function getMousepoints() {
if (resizing) {
var MouseBtnClick = event.which;
if (MouseBtnClick == 1) {
scrollTop = document.documentElement ? document.documentElement.scrollTop : document.body.scrollTop;
scrollLeft = document.documentElement ? document.documentElement.scrollLeft : document.body.scrollLeft;
mousex = event.clientX + scrollLeft;
mousey = event.clientY + scrollTop;
frame.height(mousey);
frame.width(mousex);
}
else {
resizing = false;
}
}
return true;
}
});
