我正在尝试使用json数据创建树
我有：
json数据：

已加载数据，但未显示网格。可能是什么问题？我的json数据格式是否正确？
答案 0 :(得分：2)
JSON数据和网格中都有很多错误。
我从JSON数据开始。 rows必须是数组，而不是具有属性1,2,3的对象...此类对象将没有length属性，因此将无法由jqGrid阅读。所以要解决这个问题，你应该使用
"rows":[
{
"taxonomy_id":"1",
...
},
...
]
而不是
"rows":{
"1":{
"taxonomy_id":"1",
...
},
...
}
下一个问题是jqGrid特定属性：parent，level，isLeaf，loaded。如果要加载节点的子节点而不是按需加载子节点，则应该为节点包含loaded:true。
在JSON中，您使用的某些TreeGrid属性的名称与default names不对应。因此，您应该将parent_id和is_leaf属性重命名为parent和isLeaf，或使用其他jqGrid选项
treeReader: {parent_id_field: "parent_id", leaf_field: "is_leaf"}
在jqGrid中，您必须定义树网格的最重要参数：
treeGrid: true,
ExpandColumn: 'taxonomy_id',
jsonmap中不需要colModel，并且可以移除属性。
