如何使Nicescroll仅在某些屏幕尺寸（770像素及以上）下工作

Question

当屏幕尺寸达到992px或更小尺寸时，我需要禁用NiceScroll插件，因为它使我难以触摸链接，从而使我在移动设备上的菜单混乱。我是javascript和jQuery的新手，因此感谢您的帮助。

$(function() {
  var largeScreen = false;

  $(document).ready(function() {
    if ($(window).width() > 992) {
      largeScreen = true;
    }
  });

  $(window).resize(function() {
    if ($(window).width() > 992) {
      largeScreen = true;
    } else {
      largeScreen = false;
    }
  });

  function doSomething() {
    if (largeScreen) {
      $("body").niceScroll({
        cursorcolor: "#1f3677",
        cursorborder: "2px solid #E8E8E8",
        cursorwidth: "10px",
        cursorfixedheight: 200,
        railpadding: {
          top: 0,
          right: 5,
          left: 0,
          bottom: 0
        },
        zIndex: 1,
        //emulatetouch: true,
        cursordragontouch: false,
        disableoutline: true,
        enablekeyboard: true,
        enableobserver: true,
      });

      $(".calendar-info").niceScroll({
        cursorcolor: "#1f3677",
        cursorborder: "1px solid #E8E8E8",
        cursorwidth: "5px",
        cursorfixedheight: 200,
        railpadding: {
          top: 0,
          right: 2,
          left: 0,
          bottom: 0
        },
        autohidemode: false,
        //emulatetouch: true,
        disableoutline: true,
      });
    }
  }
});
