javascript - Chrome 中的 jQuery 滚动到

Question

我在 Chrome 中遇到了 jQuery ScrollTo 的问题，它在 FF 中运行良好，但在 Chrome 中看起来很糟糕。我阅读了有关它的帖子，但我认为在我的主题代码中有所不同。请帮忙

 (function ($) {
     var h = $.scrollTo = function (a, b, c) {
         $(window).scrollTo(a, b, c)
     };

         axis: 'xy',
         duration: parseFloat($.fn.jquery) >= 1.3 ? 0 : 1,
         limit: true

     h.window = function (a) {
         return $(window)._scrollable()
     };
