JavaScript模拟右键单击代码

Question

我正在使用Selenium编写一些UI测试,并且使用Dojo工具包,我有一个JavaScript Tree控件.

我已经使用Dojo提供的示例为树的每个节点实现了一个上下文菜单,但是我需要Selenium测试来"调用"树节点上的右键单击,但我无法使其工作.测试只是不通过JavaScript模拟右键单击事件,并且上下文菜单不会显示.

有没有人有任何使用Dojo和Selenium在上下文菜单上调用右键的经验？或者对如何做到这一点有任何想法？

Answer 1

相反,尝试这样做,因为上下文菜单实际上绑定到oncontextmenu事件.

function contextMenuClick(element){
    var evt = element.ownerDocument.createEvent('MouseEvents');

    var RIGHT_CLICK_BUTTON_CODE = 2; // the same for FF and IE

    evt.initMouseEvent('contextmenu', true, true,
         element.ownerDocument.defaultView, 1, 0, 0, 0, 0, false,
         false, false, false, RIGHT_CLICK_BUTTON_CODE, null);

    if (document.createEventObject){
        // dispatch for IE
       return element.fireEvent('onclick', evt)
     }
    else{
       // dispatch for firefox + others
      return !element.dispatchEvent(evt);
    }
}

只是为了好的衡量,这里有一些关于参数的doco:

var myEvt = document.createEvent('MouseEvents');
myEvt.initMouseEvent(
   'click'          // event type
   ,true           // can bubble?
   ,true           // cancelable?
   ,window      // the event's abstract view (should always be window)
   ,1              // mouse click count (or event "detail")
   ,100           // event's screen x coordinate
   ,200           // event's screen y coordinate
   ,100           // event's client x coordinate
   ,200           // event's client y coordinate
   ,false         // whether or not CTRL was pressed during event
   ,false         // whether or not ALT was pressed during event
   ,false         // whether or not SHIFT was pressed during event
   ,false         // whether or not the meta key was pressed during event
   ,1             // indicates which button (if any) caused the mouse event (1 = primary button)
   ,null          // relatedTarget (only applicable for mouseover/mouseout events)
);

好问题！

我做了一些研究，似乎您可以像此处所示那样button触发鼠标事件，并通过将或which属性设置为 2 （此处记录）使其成为右键单击。

也许这段代码会起作用：

function rightClick(element){
  var evt = element.ownerDocument.createEvent('MouseEvents');

  var RIGHT_CLICK_BUTTON_CODE = 2; // the same for FF and IE

  evt.initMouseEvent('click', true, true,
      element.ownerDocument.defaultView, 1, 0, 0, 0, 0, false,
      false, false, false, RIGHT_CLICK_BUTTON_CODE, null);

  if (document.createEventObject){
    // dispatch for IE
    return element.fireEvent('onclick', evt)
  }
  else{
    // dispatch for firefox + others
    return !element.dispatchEvent(evt);
  }
}
