我想將圖像傳送帶添加到我正在使用聚合物(https://www.polymer-project.org/)構建的網站中。但我無法找到任何具有該功能的核心元素/紙張元素。 但是,我發現一個庫(https://github.com/addyosmani/polymer-ui-carousel),但無法實現它。請幫我在我的聚合物網站上實施圖像輪播。如何在聚合物中使用圖像傳送帶

它總是最好的發佈你到目前爲止的代碼,所以我們可以幫助你。 – ChargerIIC 2014-10-29 15:32:55
@ChargerIIC感謝您的回覆。我被困在第一個命令。即$涼亭安裝 - 保存聚合物 - 用戶 - 傳送帶。當我運行這個命令時,沒有任何事情發生,它只是繼續顯示空白光標。 – 2014-10-30 06:42:44
你好,你解決了嗎? – 2015-01-26 14:12:05
