问题描述：

for(var i=0;i<tr.length;i++){
    var td = tr[i].getElementsByTagName("td");
    if(td[2].innerHTML==time && td[3].innerHTML==cls){
        td[0].setAttribute("id","focus");
        tr[i].style.backgroundColor="green";
        var foc = document.getElementById("focus");
        foc.focus();
        cnt++;

这已经为时已晚，但是您 CAN 专注于TD元素.只需为其提供一个tabindex属性，然后执行focus().

This is a year too late, but you CAN focus to a TD element. Just give it a tabindex property, and then do a focus().

这适用于DIV元素和几乎所有其他元素.

This works for DIV elements and almost all others.

我已经在Firefox 3.5及更高版本上尝试过此操作.

I've tried this on Firefox 3.5 and up.
