安装Set up

首先需要引入jquery

在次需要引入：<script src="${ctx }/common/js/jquery.slimscroll.js" type="text/javascript"></script>

一个example如下：

html：

<div class="some-content-related-div">
<div id="inner-content-div">
<p>Lorem ipsum dolor sit amet, consectetur .... snip</p>
</div>
</div>

j代码：

$(function(){
    $('#inner-content-div').slimScroll({
        height: '250px'
    });
});

效果如下：

常用的属性如下：

width - Width in pixels of the visible scroll area. Stretch-to-parent if not set. Default: none

height - Height in pixels of the visible scroll area. Also supports auto to set the height to same as parent container. Default: 250px

size - Width in pixels of the scrollbar. Default: 7px

position - left or right. Sets the position of the scrollbar. Default: right

color - Color in hex of the scrollbar. Default: #000000

alwaysVisible - Disables scrollbar hide. Default: false

distance - Distance in pixels from the edge of the parent element where scrollbar should appear. It is used together with position property. Default:1px

start - top or bottom or $(selector) - defines initial position of the scrollbar. When set to bottom it automatically scrolls to the bottom of the scrollable container. When HTML element is passed, slimScroll defaults to offsetTop of this element. Default: top.

wheelStep - Integer value for mouse wheel delta. Default: 20

railVisible - Enables scrollbar rail. Default: false

railColor - Sets scrollbar rail color, Default: #333333

railOpacity - Sets scrollbar rail opacity. Default: 0.2

allowPageScroll - Checks if mouse wheel should scroll page when bar reaches top or bottom of the container. When set to true is scrolls the page.Default: false

scrollTo - Jumps to the specified scroll value. Can be called on any element with slimScroll already enabled. Example: $(element).slimScroll({ scrollTo: '50px' });

scrollBy - Increases/decreases current scroll value by specified amount (positive or negative). Can be called on any element with slimScroll already enabled. Example: $(element).slimScroll({ scrollBy: '60px' });

disableFadeOut - Disables scrollbar auto fade. When set to true scrollbar doesn't disappear after some time when mouse is over the slimscroll div.Default: false

touchScrollStep - Allows to set different sensitivity for touch scroll events. Negative number inverts scroll direction.Default: 200

Events

slimScroll publishes slimscroll event when scrollbar reaches top or bottom of the parent container. You can use jQuery bind method to subscribe to this

Event example：

$(selector).slimScroll().bind('slimscroll', function(e, pos){
    console.log("Reached " + pos");
});
