我在我的项目中添加了bootstrap进行响应式设计。一切都很好，但它会使标题菜单中的ABOUT US处于活动状态，但在页面加载时，HOME仍处于活动状态。但当页面完全加载时，ABOUT US变为活动状态。
我已经从CDN（link）中提取了 Bootstrap 。
下面是从第801行到第830行的引导代码。

b.prototype.process = function() {
    var a, b = this.$scrollElement.scrollTop() + this.options.offset,
        c = this.getScrollHeight(),
        d = this.options.offset + c - this.$scrollElement.height(),
        e = this.offsets,
        f = this.targets,
        g = this.activeTarget;
    if (this.scrollHeight != c && this.refresh(), b >= d) return g != (a = f[f.length - 1]) && this.activate(a);
    if (g && b < e[0]) return this.activeTarget = null, this.clear();
    for (a = e.length; a--;) g != f[a] && b >= e[a] && (void 0 === e[a + 1] || b < e[a + 1]) && this.activate(f[a])
}, b.prototype.activate = function(b) {
    this.activeTarget = b, this.clear();
    var c = this.selector + '[data-target="' + b + '"],' + this.selector + '[href="' + b + '"]',
        d = a(c).parents("li").addClass("active");
    d.parent(".dropdown-menu").length && (d = d.closest("li.dropdown").addClass("active")),
        d.trigger("activate.bs.scrollspy")
}, b.prototype.clear = function() {
    a(this.selector).parentsUntil(this.options.target, ".active").removeClass("active")
};
var d = a.fn.scrollspy;
a.fn.scrollspy = c, a.fn.scrollspy.Constructor = b, a.fn.scrollspy.noConflict = function() {
    return a.fn.scrollspy = d, this
}, a(window).on("load.bs.scrollspy.data-api", function() {
    a('[data-spy="scroll"]').each(function() {
        var b = a(this);
        c.call(b, b.data())
    })
})

我的HTML代码如下：

在这里你可以看到关于我们的li有一个ACTIVE类。
