Question

我有引导模式，其中我有桌子，我想通过按键向上关注行，下面的按键是我的代码在js但焦点不在IE中工作

var _checkKey = function (e) {
    var event = window.event ? window.event : e;
    if (event.keyCode === 13)  // the enter key code
    {
        $("tr:focus").click();
        event.preventDefault();
        return;
    }

    if (event.keyCode === 40) { //down
        event.preventDefault();

        var idx = $("tr:focus").attr("tabindex");
        if (!idx)
            idx = 0;
        else
            idx++;

        $("tr[tabindex=" + idx + "]").focus();
    }
    if (event.keyCode === 38) { //up
        event.preventDefault();

        var idx = $("tr:focus").attr("tabindex");
        idx--;

        $("tr[tabindex=" + idx + "]").focus();
    }
}

此函数通过keydown事件调用

bellow是bootstrap模式的HTML代码，

相同的代码在chrome和IE 11中工作，但如果它在bootstrap模型中则不起作用

Answer 1

尝试将其放在var事件行之后：

var event = window.event ? window.event : e;
var kCode = event.keyCode || event.which;//for IE, FireFox and Chrome
if (kCode === 13)...

至少对我来说，在Chrome和FireFox中工作

Answer 2

我有同样的问题，但没有得到任何宗教解决方案，我经历了这个

我把这段代码放在模态点击事件上。

setTimeout(()=>{
    document.getElementById("id").focus();
},9000);

//id is the name of element where you want to put your focus

Bootstrap模态焦点问题
