无法遍历JSON对象内的数组

Question

如果您打开this链接，您将获得JSON数据。当我尝试遍历它时，我可以完美地从最初的节点获取数据，即："SearchResultCount" & "SearchResultCountAll"甚至第二个对象内的两个元素。但是当我尝试从"JobCategory" & "CareerLevel" & "UserArea" descriptions对象中获取数据时会出现问题，我正在以这种方式遍历它们：

＆＃13;

＆＃13;

//Loaded through Casper JS
var doc = JSON.parse(this.getPageContent());

console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.PositionTitle)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.PositionURI)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.JobCategory[0].Name)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.CareerLevel[0].Name)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.ParentOrganizationName)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.UserArea.TextJobDescription +
  doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.UserArea.TextRequirementDescription)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.PublicationStartDate)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.OrganizationName)

＆＃13;

＆＃13;

＆＃13;

  

显示前两个数据，但其余数据显示为undefined is not an object

我不知道这是什么问题！

Answer 1

对我来说很好。 （运行下面的代码段）

＆＃13;

＆＃13;

const url = 'https://telekom.jobs/globaljobboard_api/v3/search/%7B%22JobadID%22%3A%22%22%2C%22LanguageCode%22%3A%222%22%2C%22SearchParamters%22%3A%7B%22FirstItem%22%3A1%2C%22CountItem%22%3A1000%2C%22.json';
fetch(url).then(data => data.json()).then(doc => {

console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.PositionTitle)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.PositionURI)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.JobCategory[0].Name)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.CareerLevel[0].Name)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.ParentOrganizationName)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.UserArea.TextJobDescription +
  doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.UserArea.TextRequirementDescription)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.PublicationStartDate)
console.log(doc.SearchResult.SearchResultItems[0].MatchedObjectDescriptor.OrganizationName)

});

＆＃13;

＆＃13;

＆＃13;

您的问题可能出在this.getPageContent（）中。
