var getChild = function(rootName) {
var cypher = "Match (n:Country {name:'" + rootName + "'})-[:children]->(m) return m";
db.cypherQuery(cypher, function(err, result) {
if (err) throw err;
return result;
});
}
var initJson = function(rootName, parent) {
var result = getChild(rootName);
if (result.data.length != 0) {
//TODO
var children = [];
for (var i = 0; i < result.data.length; i++) {
children[i] = { name: result.data[i].name };
initJson(result.data[i].name, children[i]);
}
parent.children = children;
return;
} else {
//TODO
return;
}
}
var createJson = function(rootName) {
json.name = rootName;
var parent = json;
initJson(rootName, parent);
console.log(JSON.stringify(json));
}
router.get('/', function(req, res) {
function_one();
res.render('index', { title: "Express" });
});
在initJson调用getChild的时候得到的返回都是undefined,我知道在getchild里面没返回出来,但是现在也没找到合适的办法,希望能有人能帮我解答一下,谢谢。
