我正在使用一个名为contextmenu的(非常老)的jQuery插件来替换某些元素上的右键单击上下文菜单。可以在here中找到此插件的源。

您将上下文菜单附加到元素,如下所示:

$(".class").contextMenu('menu_template', {
    menuStyle: {

        border: '0px',

    },
    itemStyle: {

    },
    itemHoverStyle: {

    },
    onShowMenu: function(e, menu) {

    },
    other stuff ....
})


另外,我想手动触发此菜单,并认为最简单的方法是模拟对该元素的右键单击。

我试过了:

$('.class').triggerHandler('contextmenu');




$('.class').trigger({
    type:'mousedown',
    button:2
}).trigger({
    type:'mouseup',
    button:2
});




$('.class').trigger({
    type:'mousedown',
    which:3
}).trigger({
    type:'mouseup',
    which:3
});


而只是

$('.class').trigger({
    type:'mousedown',
    which:3
})


这些都不起作用。

我确信这与该插件将自身自身附加到元素并覆盖上下文菜单有关,但是我不是JavaScript专家,所以不确定发生了什么。

如何手动触发此菜单出现?

最佳答案

你尝试过这样的事情吗?

$(document).mousedown(function(e) {
    if (e.button == 2) {
        $("span.demo1").trigger("contextmenu");
    }
    return true;
});

$(document).ready(function() {

  $(document).bind("contextmenu", function(e) {
    e.preventDefault();
  });

  $('span.demo1').contextMenu('myMenu1', {

    bindings: {

      'open': function(t) {

        alert('Trigger was ' + t.id + '\nAction was Open');

      },

      'email': function(t) {

        alert('Trigger was ' + t.id + '\nAction was Email');

      },

      'save': function(t) {

        alert('Trigger was ' + t.id + '\nAction was Save');

      },

      'delete': function(t) {

        alert('Trigger was ' + t.id + '\nAction was Delete');

      }

    }
  });
});
$(document).mousedown(function(e) {
  if (e.button == 2) {
    var element = document.getElementById("quickDemo"),
      ev;
    if (document.createEvent) {
      ev = new MouseEvent("contextmenu", {
        screenX: 0,
        screenY: 0,
        clientX: element.offsetLeft,
        clientY: element.offsetTop + element.offsetHeight,
        ctrlKey: false,
        shiftKey: false,
        altKey: false,
        metaKey: false,
        button: 2
      });
      element.dispatchEvent(ev);
    } else {
      ev = document.createEventObject();
      element.fireEvent('contextmenu', ev);
    }
  }
  return true;
});
