? ? ?photosSwipe是一個(gè)移動(dòng)端的畫廊插件，在使用時(shí)感覺偏復(fù)雜了，于是寫了一個(gè)jquery插件調(diào)用。

? ? 插件代碼如下

/** * jquery photoSwipe * Created by wuxp on 2017/4/13. */ (function ($) {/** * @param options 配置 * @callBack 畫廊渲染成功回調(diào)函數(shù) * @param holdState 在圖片預(yù)覽狀態(tài)下刷新頁面是否保持展開狀態(tài) * @param hasUseDefTem 是否使用默認(rèn)的html結(jié)構(gòu) */ $.fn.photoSwipe = function (options, callBack, holdState, hasUseDefTem) {//var photoSwipes=[];

$("body").append($(html)); }})(jQuery); 調(diào)用截圖 img標(biāo)簽外層使用data-photo標(biāo)記 js代碼調(diào)用 關(guān)鍵代碼 data-big存放大圖，data-title存放標(biāo)題文本內(nèi)容

其他的可以看代碼，邏輯比較簡單

總結(jié)
