如何用jQuery区分鼠标左键和右键

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');
});

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! */
    }
});

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
    }
});

事件。which === 1确保它是一个左键点击(当使用jQuery时)。

但您还应该考虑修改器键:ctrlcmdshiftalt

如果你只对捕捉简单的、未修改的左键点击感兴趣，你可以这样做:

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...
  }
});

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.

从jQuery 1.1.3版本开始，事件。使事件正常化。keyCode和事件。charCode，这样就不必担心浏览器兼容性问题。关于event.which的文档

事件。它将分别给1、2或3个鼠标左、中、右按钮，这样:

$('#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!');
    }
});
