How to re-enable the context menu in this case?

问题

document.addEventListener('contextmenu', function (e) {
    e.preventDefault()
    e.stopPropagation()
    e.returnValue = false
    e.cancleBubble = true
})

No way?

Edit: document.oncontextmenu = null does not work.

P.S. I cannot have the reference of the listener function since I am not the owner of the site preventing the context menu.

回答1:

If you are really desperate, try adding this before the addEventListener is called. It works in both FF and Chrome. I didn't check anything else.

document.superListener = document.addEventListener;
document.addEventListener = function(type, listener, useCapture){
    if(type != 'contextmenu')
        document.superListener(type, listener, !!useCapture);
};

It may not be the best way to do things, but it should be the job done on your specific example :)

I use my bookmarklet in such cases:

javascript:(function(w){
    var arr = ['contextmenu','copy','cut','paste','mousedown','mouseup','beforeunload','beforeprint'];
    for(var i = 0, x; x = arr[i]; i++){
        if(w['on' + x])w['on' + x] = null;
        w.addEventListener(x, function(e){e.stopPropagation()}, true);
    };
    for(var j = 0, f; f = w.frames[j]; j++){try{arguments.callee(f)}catch(e){}}})(window);

Rather than disabling the context menu, why don't you assign the right click event?
