将包含 2 个属性的节点插入 Neo4j 数据库后，如何从 REST API 查询响应中提取属性（“名称”和“电话”）？我查询数据库的脚本是：

<script>
function query_database()
{
var restServerURL = "http://localhost:7474/db/data"; //local copy on windows machine
$.ajax({
  type:"POST",
  url: restServerURL + "/cypher",
  accepts: "application/json",
  dataType:"json",
  data:{
         "query" : "start n  = node(*) return n",
         "params" : {}
  },
  success: function(data, xhr, textStatus){
                  //alert("query success!");
          //process query results here

         alert(JSON.stringify(data, null, 4));
  },
  error:function(jqXHR, textStatus, errorThrown){
                   alert(errorThrown);
  }
});
}//end of query database

显示"alert(JSON.stringify(data, null, 4));"以下内容：

{
"columns": [
    "n"
],
"data": [
    [
        {
            "paged_traverse": "http://localhost:7474/db/data/node/3761/paged/traverse/{returnType}{?pageSize,leaseTime}",
            "outgoing_relationships": "http://localhost:7474/db/data/node/3761/relationships/out",
            "data": {
                "phone": "123.456.7890",
                "name": "jeff "
            },
            "traverse": "http://localhost:7474/db/data/node/3761/traverse/{returnType}",
            "all_typed_relationships": "http://localhost:7474/db/data/node/3761/relationships/all/{-list|&|types}",
            "all_relationships": "http://localhost:7474/db/data/node/3761/relationships/all",
            "property": "http://localhost:7474/db/data/node/3761/properties/{key}",
            "self": "http://localhost:7474/db/data/node/3761",
            "properties": "http://localhost:7474/db/data/node/3761/properties",
            "outgoing_typed_relationships": "http://localhost:7474/db/data/node/3761/relationships/out/{-list|&|types}",
            "incoming_relationships": "http://localhost:7474/db/data/node/3761/relationships/in",
            "incoming_typed_relationships": "http://localhost:7474/db/data/node/3761/relationships/in/{-list|&|types}",
            "extensions": {},
            "create_relationship": "http://localhost:7474/db/data/node/3761/relationships"
        }
    ]
]

}

非常感谢，

在您的示例中，您将从响应数据对象中获取姓名和电话，如下所示：

var name = data.data[0][0].data.name;
var phone = data.data[0][0].data.phone;
alert("Name is " + name + "\nPhone is " + phone);

JSFiddle 在这里。
