使用javascript捕获新的浏览器窗口打开事件

Question

is it possible to capture new browser window open event with javascriptand call some functions before? Thanks

Answer 1

window doesn't have a beforeload event.

Something like this could work, but keep in mind that overriding window.open is pretty dangerous.

var windowOpen = window.open;

window.open = function(url, name, features, replace) {
    alert("opening a window");
    // do other stuff here
    windowOpen(url, name, features, replace);  
}

window.open("http://www.google.com");
