覆盖FF中的F1键，chrome，ie。 F1上的ie8 / chrome上键盘和FF按键？关于< tab>在输入字段？ [英] Overriding the F1 key in FF, chrome, ie. Is F1 on ie8/chrome on keyup and in FF on keypress? What about <tab> in an input field?

问题描述

我使用jquery创建命名空间事件。当我使用下面的代码= 112函数，一个函数，bool = false，一切工作正常在FF和F1键提交到我的功能，该事件不起泡在新标签中打开firefox帮助。 p>

I'm creating namespaced events with jquery. When I use the following function with code=112, a function, bool=false, everything works fine in FF and the F1 key submits to my function and the event does not bubble up to open the firefox help in a new tab.

function bindKeyFunc(code, func, bool){
    $(document).bind('keypress.' + code, function(e){
        var c = (e.keyCode ? e.keyCode : e.which);
        //console.log(c);
        if ( code == c) {
            //e.stopPropagation();
            //e.preventDefault();
            func();
            return bool;
        }
    });
}

在chrome和ie8我的事件监听器不会触发，即使我取消注释stopPropagation和preventDefault调用。

In chrome and ie8 my event listener does not fire and the regular help occurs instead, even if I uncomment the stopPropagation and preventDefault calls.

同样，当我尝试接管< tab> 键为我自己的目的，它工作在FF的辉煌，但我的事件不会触发chrome或ie8，并且选项卡的默认动作改为：

Similarly, when I try to take over the <tab> key for my own purposes, it works splendidly in FF but my event doesn't fire in chrome or ie8 and the default action for the tab fires instead:

    $('input#manual-total').bind('keypress.dep', function(e) {
        var code = (e.keyCode ? e.keyCode : e.which);
        if ( code==9 ){
            $('div#formset').show();
            $(next).focus()[0].select();
            return false;
        }
    });

推荐答案

在浏览器中映射特殊键是一个混乱。特别是， IE当然不会为功能键启用按键事件。 onkeydown / up可能在IE上工作，虽然。许多键由不同的浏览器以不同的方式处理不正确。我强烈怀疑有一种处理F1的跨浏览器方法。抱歉;我知道这不是你想要的答案，但我相信这是真的。

Good luck. Mapping of special keys in browsers is a mess. In particular, IE certainly does not fire keypress events for function keys at all. onkeydown/up may work on IE, though. Many keys are handled incorrectly, in different ways by different browsers. I strongly doubt there is a cross-browser method of handling F1. Sorry; I know that's not the answer you wanted, but I believe it's the truth.

Do read the linked article, particularly the occasional warnings about "When I discovered that I decided not to risk my sanity by performing further punctuation character experiments." and the like. :)
