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');
});

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
}
});

你也可以绑定到contextmenu并返回false:
$('selector').bind('contextmenu', function(e){
e.preventDefault();
//code
return false;
});

或者你可以做一个快速插件，做同样的事情:
(function( $ ) {
$.fn.rightClick = function(method) {
$(this).bind('contextmenu rightclick', function(e){
e.preventDefault();
method();
return false;
});
};
})( jQuery );

使用.on(…)jQuery >= 1.7
$(document).on("contextmenu", "selector", function(e){
e.preventDefault();
//code
return false;
}); //does not have to use `document`, it could be any container element.
演示:http://jsfiddle.net/maniator/WS9S2/283/
$("body").on({
click: function(){alert("left click");},
contextmenu: function(){alert("right click");}
});
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! */
}
});

// 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}`;
}
});

对于那些不知道是否应该使用事件的人。在普通JS或Angular中:现在已弃用，所以更喜欢使用event。按钮。
注意:使用此方法和(mousedown)事件:
左键按关联到1 右键单击与2关联 滚动按钮按下与4相关联
and (mouseup)事件将不会返回相同的数字，而是0。
