works in FF but not in Chromium

[fel]

i have this script (and more but the problem is in these piece of code, i think)

So, in FF i have a image and it moves with arrow keys. But in Chromium, the image is static, the action of the buttons is null, nothing happens

any help?

function desenhaBonecoBx(){
    clear();
    context2D.drawImage(bonecoBottom, x, y);
    y += 10 * yDirection;
}



//mover boneco
function moverBoneco(dir){
    if (dir == "esquerda") {
        desenhaBonecoDir();
    }
    if (dir == "direita") {
        desenhaBonecoEsq();
    }
    if (dir == "cima") {
        desenhaBonecoCim();
    }
    if (dir == "baixo") {
        desenhaBonecoBx();
    }
}

//teclas
function teclar(evt){
    if (evt.keyCode == 38) {
        moverBoneco('cima')
    }
    if (evt.keyCode == 40) {
        moverBoneco('baixo')
    }
    if (evt.keyCode == 37) {
        moverBoneco('esquerda')
    }
    if (evt.keyCode == 39) {
        moverBoneco('direita')
    }
}

window.addEventListener('keypress', teclar, true)

capturing the keycode with onkeypress is inconsistent along the browsers. have you tried onkeydown?

I hope you know that you are coding in HTML5, which is not well implemented in all the browsers, so far. Have you used the HTML5 syntax?

thanks

the question is. I test in FF, and if i use keypress, the image move when i have the key pressed, however, in chromium, if i use keypress, nothing happen, but if i use keydown it works in chromium like a keypress

a bit strange

It's very important to check out the links that Kor posted as well - there's a bunch on inconsistencies between browsers with what key registers what code after being called with one event versus another.

Checking out those links will show you a table which will clarify it all.

Can you post a full code (HTML included), please? Or a link to a test page? HTML code is important in relationship with the JavaScript code.

And. once again: do you know that you try an HTML5 feature? Do you know something about the history of HTML, XHTML, JavaScript and all the cross-browser's problems all these years so far?

[fel]

at the moment i don't have any server, and it is much code to post (more than 500lines and 4 files ).

I used the keydown, and it is solved more or less

Yes i know that is html5, and i have some knowledge about programming. Yes it is true, the interoperability in the differents browsers are a big problem for all developers

thanks one more time

[Kor]

You could attach the files. Or you could isolate the representative HTML part of the code and post it (but, most of the time the full picture is important - some unexpected small errors in one of the part of the code can spoil something it it opposite part of it )

It is hard for us to reproduce the error, if we have not enough information. Merely when it comes about cross-browser issues.

My tests indicate that Chrome does not fire a keypress event for the cursor keys.

My tests indicate that Chrome does not fire a keypress event for the cursor keys.

That brings us to my first presumption: onkeypress event is inconsistent. So: what about onkeydown?
