+1. 发现url添加json格式, 支持设置标签样式
+* 样式属性可以搜索 [FleboxLayout子元素支持的属性介绍](https://www.jianshu.com/p/3c471953e36d)
+* 样式属性可省略,有默认值
+```json
+[
+  {
+    "title": "xxx",
+    "url": "",
+    "style": {
+      "layout_flexGrow": 0,
+      "layout_flexShrink": 1,

 1. 默认规则新增类似`jsonPath`的索引写法 by bushixuanqi
 * 格式形如 `[index,index, ...]` 或 `[!index,index, ...]` 其中`[!`开头表示筛选方式为排除，`index`可以是单个索引，也可以是区间。
