#1. 概述 ---- 在我们开发过程中，有时候服务器会给你一个 xxx.js文件或者xxx.html文件，需要你把这个文件放到 as 下的 assets目录 下边，如果该 xxx.js或者xxx.html 文件 里边的数据是类似于下边代码，只是想要获取到每个银行的 bankName和bankCode的话， 具体有2种处理方式： 第一种：将 assets 下的整个 xxx.js或者xxx.html 文件加载成一个 webview，通过webview调用 js或者html中的 方法； 第二种：将这些对应的 bankCode和bankName 单独抽取出来，自己写成一个xml文件，然后放到本地，去解析xml文件； ``` var bankcardList = [{ bankName: "中国邮政储蓄银行", bankCode: "PSBC", patterns: [{ reg:
