javascript:如何检查是否在上下文菜单新选项卡上单击了链接

Question

是否可以检查链接是否被单击以在新窗口中打开？我的意思是 ctrl 或 shift 键按下是明确的，您可以处理此事件，但是浏览器中的右键单击上下文菜单怎么样？您可以在此处单击在另一个窗口中打开的上下文菜单项..

打开上下文菜单时触发 Jquery context() 方法:

$("a").contextmenu(function() {
  alert("context");
});

$("a").click(
    if (evnt.ctrlKey || evnt.shiftKey || evnt.metaKey || 
        (evnt.button && evnt.button == 1)){
        alert("link clicked");
    }
);

我想出了这个解决方案，它非常 hacky 和 ​​DIY，但应该可以解决问题。

诀窍是使用此 jQuery 插件创建您自己的上下文菜单:

这不会在 SO 上执行，我建议在 JSFiddle 上运行它:JSFiddle

$(function() {
  $.contextMenu({
    selector: '.context-menu-one',
    callback: function(key, options) {

      var m = "clicked: " + key;
      window.console && console.log(m);

      switch (key) {
        case "open_new_window":
          console.log($(this));
          //var win = window.open($(this)[0].href, '_blank');
          window.open($(this)[0].href,'_blank');
          //win.focus();
          break;
        case "cut":
          break;
      }
    },
    items: {
      "open_new_window": {
        name: "Open link in new tab",
        icon: "edit"
      },
      "cut": {
        name: "Cut",
        icon: "cut"
      }
    }
  });
});
