Jquery Localscroll ie8

Question

我遇到了jquery localscroll插件的问题，它似乎在除IE8之外的所有浏览器上都能正常工作。

在IE8中，它向下滚动并分开工作，不会滚动到正确的ID。

$(document).ready(function(){

        $('#nav').localScroll({ duration: 2000, easing: "swing"});
        //.parallax(xPosition, speedFactor, outerHeight) options:
        //xPosition - Horizontal position of the element
        //inertia - speed to move relative to vertical scroll. Example: 0.1 is one tenth the speed of scrolling, 2 is twice the speed of scrolling
        //outerHeight (true/false) - Whether or not jQuery should use it's outerHeight option to determine when a section is in the viewport
        $('.parallax__one').parallax("50%", 0.3);
        $('.parallax__two').parallax("50%", 0.4);
        $('.slideleft').parallax("50%", 0.4);
        $('.parallax__four').parallax("50%", 0.3);
        $('.parallax__five').parallax("50%", 0.6);
        $('.return8').parallax("65%", 2);
    });

<header class="header">
<div class="container">
    <ul class="menu" id="nav">
    <p class="ir header__logo"><span><a href="#one" class="js-action" date-action="one">Logo</a></span></p>
        <li class="menu__list"><a href="#two" class="js-action" date-action="two">01<b>about</b></a></li>
        <li class="menu__list"><a href="#three" class="js-action" date-action="three">02<b>the product</b></a></li>
        <li class="menu__list"><a href="#four" class="js-action" date-action="four">03<b>the future</b></a></li>
        <li class="menu__list"><a href="#five" class="js-action" date-action="five">04<b>contact</b></a></li>

    </ul>

</div>
