disallow window open in javascript

Question

How can I disable window.open() using html, javascript, jQuery...?
I mean block any window open attempt, making "not-working" all existing window.open() functions.
Which are the best ways to do it? (working also in case of iframes)

Answer 1

//for iframes:
$.each($('iframe'), function() {
    this.contentWindow.open = function (url, windowName, windowFeatures) {
        //iframe window.open caught!
    };
});

//for window:
window.open = function (url, windowName, windowFeatures) {
    //window.open caught!
};

Answer 2

You'd be polluting the global namespace, but you could simply override the window.open method...

window.open = function (url, windowName, windowFeatures) {
    console.log('not opening a window');
}
