<input type="hidden" name="data" id="data" value='[{"name":"北京","value":1,"children":[{"name":"北京市1","value":12,"children":[{"name":"朝阳区1","value":13,"children":[]},{"name":"朝阳区2","value":14,"children":[]},{"name":"朝阳区3","value":15,"children":[]},{"name":"朝阳区4","value":16,"children":[]}]},{"name":"北京市2","value":17,"children":[]},{"name":"北京市3","value":18,"children":[]},{"name":"北京市4","value":19,"children":[]}]},{"name":"天津","value":2,"children":[{"name":"天津市1","value":51,"children":[]}]}]' />
[{},{}] 正确
[{},{},] 转json对象是报错 (直接写数组不报错)
var Jsondata = $("#data")[0].defaultValue;
var jsonobj = JSON.parse(Jsondata);
layui.formSelects.data('select15', 'local',
{
arr: jsonobj,
linkage: true ////开启联动模式
}
);
