问如何将事件绑定到弹出窗口？

EN

// the popup window is referenced by "display.window"
// #map is a <canvas> element occupying 100% of the new window

// I'll just try passing in the context first...
$(display.window, "#map").keydown(function(e) {
    // do stuff
});

// maybe the other way around?
$("#map", display.window).keydown(function(e) {
    // do stuff
});

// what if I just try to add the event right to the window?
$(display.window).keydown(function(e) {
    // do stuff
});

// nope, maybe bind will do the trick
$(display.window).bind(function(e) {
    // do stuff
});

// maybe the new window's DOM isn't loaded yet?
$(display.window).ready(function() {
    $(this).keypress(function(e) {
        // do stuff
    });
});
