Ext3.4-EXT之嵌套表格的实现

时间：2022-12-02 06:43:22
其中使用到的"RowExpander.js"为extjs官方示例中自带的。

实现这个嵌套表格要注意两点技巧：

1 提供给外层表格的dataStore的数据源以嵌套数组的形式表示细节区的数据,如下面的黑体所示。

  
  1. var testData=[
  2. ["lugreen","男",26,[["数学",100],["语文",150]]]
  3. ,["lisi","男",25,[["数学",100],["语文",150]]]
  4. ,["zhangsan","男",27,[["数学",120],["语文",158]]]
  5. ];

使用数组集中record对象的json属性来获取以细节区数据

var data=r.json[3];

2 在rowExpander的 expand事件中添加嵌套表格.
