很喜歡在插件上進(jìn)行修修改改。Swiper3是我很喜歡使用的一個(gè)輪播圖插件。在這個(gè)插件上面，不知道是我改動(dòng)的原因，還是下載的版本原因，我現(xiàn)在使用的這個(gè)版本的js竟然有大部分屬性兼容ie9（感到很奇跡?。。?。

一，這個(gè)版本在ie9上面兼容什么呢？

1. 兼容自定義高度；

傳統(tǒng)swiper和此版本swiper對(duì)比圖：（如圖1）

圖1
如果使用改動(dòng)版本的js，可改善這個(gè)問(wèn)題。

1. 左右按鈕有效，位置不變；
2. 分頁(yè)器有效，且可點(diǎn)擊跳轉(zhuǎn)到對(duì)應(yīng)banner上；
3. Loop循環(huán)屬性有效；
4. 禁止切換有效；
5. 支持一行多列（slidesPerView參數(shù)）；
6. Swiper的回調(diào)函數(shù)有效；
7. breakpoints斷點(diǎn)參數(shù)可用；
8. 未知。

改動(dòng)版本在IE9上不兼容什么？

1. 不兼容自動(dòng)切換；
2. 不支持多列1行或者多列多行；
3. 未知。

 

二，Swiper（可復(fù)制以下代碼，保存為js放于項(xiàng)目中）；
