我明白了.目标应该是一个可以聚焦的标签，比如链接，如果不是，我的情况是一个div，应该将目标的tabindex设置为-1.

I get it. The target should be a tag that can be focused, like a link, if not, which is my case a div, should set tabindex of the target as -1.

我的 jQuery 解决方案，带有 ScrollTo 插件，是:

My jQuery solution, with ScrollTo plug-in, is:

$("a[href^='#']")
    .click(function(evt){
        var j = $(evt.currentTarget);
        var anchorTarget = j.attr("href");
        $("body")
            .scrollTo(anchorTarget, 500, {
                onAfter:function() {
                    window.location.hash = anchorTarget.substr(1);
                    $(anchorTarget).attr("tabindex",-1).focus();
                }
            });

        evt.preventDefault();
    });
