Question

我试图通过Javascript（查询控制台）将一些三元组插入到表单的JSON文档中

declareUpdate();
xdmp.documentInsert('/aem/5/content/demo-spark/en_GB/automation_article.json',
{
  "triple" : {
    "subject" : "https://content.ea.com/aem/5/content/demo-spark/en_GB/automation_article2.json",
    "predicate" : "https://content.ea.com/iri/author",
    "object" : "jasonmoore"
  },
  "triple" : {
    "subject" : "https://content.ea.com/aem/5/content/demo-spark/en_GB/automation_article2.json",
    "predicate" : "https://content.ea.com/iri/id",
    "object" : "automation_article2"
  },
  "triple" : {
    "subject" : "https://content.ea.com/aem/5/content/demo-spark/en_GB/automation_article2.json",
    "predicate" : "https://content.ea.com/iri/dateCreated",
    "object" : "2015-08-14 09:38:10 GMT-7:00"
  },
  "content" : {
  . . .
  }
});

然而，当我查看新创建的文档时，只有最后一个三元组存在，其他两个缺失。

我需要做什么才能在同一份文件中获得前两个三元组？

我尝试将其添加为评论，但它不会使用换行符对其进行格式化。所以这只是Jose Hermosilla Rodrigo答案的延伸。

由于您不能拥有许多具有相同名称的对象键，因此请使用数组：

declareUpdate();
xdmp.documentInsert('/aem/5/content/demo-spark/en_GB/automation_article.json',
{ "triples": [
  { "triple": {
    "subject" : "https://content.ea.com/aem/5/content/demo-spark/en_GB/automation_article2.json",
    "predicate" : "https://content.ea.com/iri/author",
    "object" : "jasonmoore"
  }},
  { "triple": {
    "subject" : "https://content.ea.com/aem/5/content/demo-spark/en_GB/automation_article2.json",
    "predicate" : "https://content.ea.com/iri/id",
    "object" : "automation_article2"
  }},
...
],
  "content" : {
  . . .
  }
});

JSON对象存储键值对。钥匙是独一无二的。

var obj = {
  a : 'This is a property, but it will be overwritten',
  a : 'Im really the value of a property'
};

console.log(obj);

这也是一样的说法：

var obj = {
  a : 'This is a property, but it will be overwritten'
};

obj['a'] = 'Im really the value of a property';

console.log(obj);

现在你可以想一想发生了什么：每次你试图在密钥"triple"中插入时都会覆盖它包含的内容，最后存储的值是最后一个。

var myDbObject = {};
var obj = {
  "triple" : {
    "subject" : "https://content.ea.com/aem/5/content/demo-spark/en_GB/automation_article2.json",
    "predicate" : "https://content.ea.com/iri/author",
    "object" : "jasonmoore"
  },
  "triple" : {
    "subject" : "https://content.ea.com/aem/5/content/demo-spark/en_GB/automation_article2.json",
    "predicate" : "https://content.ea.com/iri/id",
    "object" : "automation_article2"
  },
  "triple" : {
    "subject" : "https://content.ea.com/aem/5/content/demo-spark/en_GB/automation_article2.json",
    "predicate" : "https://content.ea.com/iri/dateCreated",
    "object" : "2015-08-14 09:38:10 GMT-7:00"
  }
};

Object.keys(obj).forEach(key=>{
  myDbObject[key] = obj[key];
});

console.log(myDbObject);

如何在Marklogic JSON文档中插入多一个三元组？
