JavaScript simulate right click through code
I am writing some UI tests using Selenium and i have a JavaScript Tree control, using the Dojo toolkit.
I have implemented a context menu for each node of the tree using the examples that Dojo provide, but I need the Selenium test to "invoke" the right click on the tree node, but I cannot get this to work. The tests simply do not simulate the right-click event through JavaScript, and the context menu does not show up.
Has anyone had any experience in invoking the right click on a context menu using Dojo and Selenium? Or have any ideas as to how to do it?
Solution 1:
try this instead, reason what things didn't quite work is that the context menu is in fact bound to the oncontextmenu event.
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);
}
}
Solution 2:
Just for good measure, here is a bit of doco on the parameters:
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)
);

Great question!
I did some research, and it seems like you can fire a mouse event like is shown here, and make it a right-click by setting the button
or which
property to 2 (documented here).
Perhaps this code will work:
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);
}
}
Solution 4:
Here is a more correct version if you do not care about where the context menu gets fired up
function fireContextMenu(el) {
var evt = el.ownerDocument.createEvent("HTMLEvents")
evt.initEvent('contextmenu', true, true) // bubbles = true, cancelable = true
if (document.createEventObject) {
return el.fireEvent('oncontextmenu', evt)
}
else {
return !el.dispatchEvent(evt)
}
}
If you do, we may have to use the previous one, fix up it's behaviour in IE, and populate the screenX, screenY, clientX, clientY etc appropriately
