$ (window) .keypress (function ()) not working in IE7?

Question

This keypress event works fine for me in Chrome and Firefox, but just not used in IE7:

$(window).keypress(function(e) {
    alert('hello world');
});

Does anyone know alternatives for IE7?

Or is it the error above in my JavaScript, which means that it is not caught in IE7 - in this case, how can I debug it? I have script errors included in IE, but nothing appears.

Answer 1

IE does not support key events on window.

Put it in place document.

$(document).keypress(function(e) {
    alert('hello world');
});

IE7 , , $(document) $(window). - :

$(document).keypress(function(e) {
    alert("hello world");
});
