* cityPicker
* v-1.0.0
* dataJson [Json] json数据，是html显示的列表数据
* selectpattern [Array] 用于存储的字段名和默认提示 { 字段名，默认提示 }
* shorthand [Boolean] 用于城市简写功能，默认是不开启(false)
* storage [Boolean] 存储的值是数字还是中文，默认是(true)数字
* linkage [Boolean] 是否联动，默认(true)
* renderMode [Boolean] 是模拟的还是原生的;只在type是selector才有效,默认是(true)模拟
* code [Boolean] 是否输出城市区号值，默认(false)，开启就是传字段名('code')
* search [Boolean] 是否开启搜索功能，默认（true）
* level [Number] 多少列 默认是一列/级 (3)
* onInitialized [Attachable] 组件初始化后触发的回调函数
* onClickBefore [Attachable] 组件点击显示列表触发的回调函数(除原生select)
* onForbid [Attachable] 存在class名forbid的禁止点击的回调
* choose-xx [Attachable] 点击组件选项后触发的回调函数 xx(级名称/province/city/district)是对应的级的回调
