Trigger right-click

问题

I am trying to late-bind context menus to elements, using the ContextMenu plugin. So on the first right-click on those elements, I would like to :

1. intercept the right-click through a live event on a certain "uncontextmenued" class,
2. determine if the data('events').contextmenu exists,
3. if not, attach the context-menu (and change the class to avoid re-throwing this live process),
4. re-throw the right-click event to show the right-click.

I'm having trouble with the last item. jQuery allows to .click() or to .trigger('click'), which simulate a left-click, but there seems not to be a way to fire a right-click event through trigger.

Or is there?

回答1:

You can trigger it by

$('#element').trigger({
    type: 'mousedown',
    which: 3
});

回答2:

There is a newer way to do this:

$('#element').triggerHandler('contextmenu');

Documentation can be found here.

Similar to this, but I'm not sure if you may be referring to jQuery UI data, but.

$('#element').mousedown(function(event) 
{
    if(event.which == 3)
    {
        if(typeof($(this).data('events')) === 'undefined')
        {
            $(this).data('events', { somedata: 'hello' });
        }
        else
        {
            // "re-throw" right click context menu
        }
    }
});
