leonaScroll-1.1最新版-竖向
leonaScroll-1.1.js
欢迎使用leonaScroll-1.1.js,此滚动条仅支持竖向滚动,如您在使用过程中发现更多问题,欢迎指正!
更新:1.1版本
1、修复了前面初始版本中的一些bug,比如不能自适应用户的文本内容,css文件繁杂
2、用户只需调用一个方法即可使用该插件,无需按照原来的class类名去添加和定义你的滚动条文本域及外层元素,显得更为自由
3、增设了滚动条宽度、上下微调按钮高度,滚动文本区域的设置
4、增设了文本内容未超出时是否显示滚动条可选设置选项,如不设置,默认为不显示
5、增设了滚动文本宽度的可选设置选项,如不设置会自动为您适配到最佳宽度
使用方法:
1、建立好您的Html,引用jquery框架与mousewheel插件,及我们的leonaScroll-1.1.js插件
2、使用$("").LeonaScroll({speed,scroll_text,sWidth,updownH})调用插件
3、属性说明:
speed 滚动速度,必须
scroll_text 滚动文本内容class,必须
sWidth 滚动条宽度,必须
updownH 上下微调按钮高度,必须
scrollbar 文本内容未超出时是否显示滚动条,显示为false,不显示为true,可选,默认为true
text_width 滚动文本宽度,可选
leonaScroll-1.0仅供学习参考使用,该版本为本人学习时思路版,尚有不足,新版本修复了很多问题,但仍然存在着二次调用问题。不过已经有了解决方案,只是本人比较赖,没有修复,等待1.2版本修复吧!哈哈!
当然如果有人使用后遇到bug或者不方便的地方,欢迎提出,以便本人继续改进。
学习之余写的小插件,如有什么不足之处,还望见谅。
最后感谢在本插件开发过程中,帮助和解答过我疑问的朋友。尤其感谢Delevin先生的大力解惑!
