关于网上的脚本问题

Question

<li class="cd-selected" data-menu="index"> <a href="#"> <span> <svg class="nc-icon outline" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="64px" height="64px" viewBox="0 0 64 64"><g transform="translate(0, 0)"> <polyline data-cap="butt" fill="none" stroke="#9e85d0" stroke-width="2" stroke-miterlimit="10" points="10,24.9 10,60 26,60 26,44 38,44 38,60 54,60 54,24.9 " stroke-linejoin="square" stroke-linecap="butt"></polyline> <polyline data-color="color-2" fill="none" stroke="#9e85d0" stroke-width="2" stroke-linecap="square" stroke-miterlimit="10" points=" 4,30 32,6 60,30 " stroke-linejoin="square"></polyline> <rect data-color="color-2" x="26" y="24" fill="none" stroke="#9e85d0" stroke-width="2" stroke-linecap="square" stroke-miterlimit="10" width="12" height="10" stroke-linejoin="square"></rect> </g></svg> </span> <em>Intro</em> </a> </li>以上是从网上下载的一个脚本中的一段，其实就是个导航，span部分就是个图形，主要是我在想用的时候，修改 href ，可是修改后根本不会跳转。chrome提示 XMLHttpRequest cannot load file:///Users/user/Projects/%E7%BD%91%84%9A%E6%9C%AC/jiaoben3312-%91%E7%AB%99%E4%B8%BB5%E5%AF%BC%E8%88%AA/projects.html.
