javascript - 如何访问下面的 json 值

Question

您好，我正在尝试访问值 DepartmentId，但由于值不存在而出现错误。

当我尝试访问 DepartmentId 时，我可以获得大括号内的值，但出现错误。

下面是我的 map 函数

 r.PrimarySearchResults.map((value) => {
console.log(value)}
)

我可以得到 value.Rank 但不能得到 value.DepartmentId

下面是我得到的JSON对象。这是我展开对象的时候。

{Rank: "16.9111518859863", DocId: 
"17598046715456", Title: "HubSite", SPSiteUrl: "https://amoghtelkar.sharepoint.com/sites/hubsite2", 
WebTemplate: "SITEPAGEPUBLISHING", …}
Culture: "en-US"
DepartmentId: "{3d408bfe-9172-4df5-b36e-863c066e9ada}"
DocId: "17598046715456"

尝试安排您的 JSON 对象，似乎 DepartmentId 不包含在 JSON 中

{
    Rank: "16.9111518859863", 
    DocId: "17598046715456", 
    Title: "HubSite", 
    SPSiteUrl: "https://amoghtelkar.sharepoint.com/sites/hubsite2", 
    WebTemplate: "SITEPAGEPUBLISHING", }

Culture: "en-US" DepartmentId: "{3d408bfe-9172-4df5-b36e-863c066e9ada}" DocId: "17598046715456" PartitionId: "51ddbb65-42e8-4906-82e4-8d97c6626ef7" Rank: "16.9111518859863" RenderTemplateId: "~sitecollection/_catalogs/masterpage/Display Templates/Search/Item_Default.js" ResultTypeId: "0" SPSiteUrl: "https://amoghtelkar.sharepoint.com/sites/hubsite2" SiteId: "3d408bfe-9172-4df5-b36e-863c066e9ada" Title: "HubSite" UniqueId: "{F08C7BCE-C886-4A09-AA22-D66879DD5252}" UrlZone: "0" WebId: "edec632a-5671-49bd-a7fe-27a6e851f09a" WebTemplate: "SITEPAGEPUBLISHING"

试试这个:

var value = JSON.parse(value);console.log(value.DepartmentId);
