Nicescroll scroll bar plug-in is a very powerful scroll bar plug-in based on jQuery. It does not require additional css and is compatible with almost all browsers. IE6+ only requires a piece of code to implement, is very intrusive, the style is fully customizable, supports touch events, and can be used on touch screens.

Introduce the core file, and the plug-in needs to introduce the jquery library of version 1.5.X or above

The simplest usage is as follows:


$(document).ready(
 function() { 
  $("html").niceScroll();
 }
);

Note: Must be initialized in $(document).ready!

Hide scroll bar


$("#myp").getNiceScroll().hide();

Detect whether the scroll bar is resized (when the window changes size)


$("#myp").getNiceScroll().resize();

Scroll to a certain position


$("#myp").getNiceScroll(0).doScrollLeft(x, duration); // Scroll X Axis
$("#myp").getNiceScroll(0).doScrollTop(y, duration); // Scroll Y Axis

Various parameters can be added


$(document).ready(
 function() { 
  $("#thisp").niceScroll({cursorcolor:"#00F"});
 }
);

Configuration parameter table


$("#thisp").niceScroll({
    cursorcolor: "#424242", // 改变滚动条颜色,使用16进制颜色值
    cursoropacitymin: 0, // 当滚动条是隐藏状态时改变透明度, 值范围 1 到 0

    cursorwidth: "5px", // 滚动条的宽度,单位:便素
    cursorborder: "1px solid #fff", // CSS方式定义滚动条边框

    scriptpath: "" // 为boxmode图片自定义路径 ("" => same script path)
    preventmultitouchscrolling: true // 防止多触点事件引发滚动
  });

Also note: When using multiple nicescroll plug-ins on the same page, hide the used nicescroll in time When loading an object, you need to show it first and then resize it.

When the plug-in is placed in a container with absolute float and the top value is set, there will be a problem with the top of the plug-in. The solution is to use the railoffset attribute of the plug-in:


railoffset, you can add offset top/left for rail position (default:false)
