前端开发之可以让swiper3兼容ie9的js
发布时间：2025-03-05 点击：26
很喜欢在插件上进行修修改改。swiper3是我很喜欢使用的一个轮播图插件。在这个插件上面，不知道是我改动的原因，还是下载的版本原因，我现在使用的这个版本的js竟然有大部分属性兼容ie9（感到很奇迹！！）。一，这个版本在ie9上面兼容什么呢？ 兼容自定义高度；传统swiper和此版本swiper对比图：（如图1）
图1
如果使用改动版本的js，可改善这个问题。 左右按钮有效，位置不变； 分页器有效，且可点击跳转到对应banner上； loop循环属性有效； 禁止切换有效； 支持一行多列（slidesperview参数）； swiper的回调函数有效； breakpoints断点参数可用； 未知。改动版本在ie9上不兼容什么？ 不兼容自动切换； 不支持多列1行或者多列多行； 未知。二，swiper（可复制以下代码，保存为js放于项目中）；

如果使用改动版本的js，可改善这个问题。 左右按钮有效，位置不变； 分页器有效，且可点击跳转到对应banner上； loop循环属性有效； 禁止切换有效； 支持一行多列（slidesperview参数）； swiper的回调函数有效； breakpoints断点参数可用； 未知。改动版本在ie9上不兼容什么？ 不兼容自动切换； 不支持多列1行或者多列多行； 未知。二，swiper（可复制以下代码，保存为js放于项目中）；
