解析一個大的JSON字符串

-1

所以我有一個相當大的JSON字符串，它有一個相當先進的結構（至少對我來說），我想用javascript解析。下面是它的讀者的版本（這是一個例子）：解析一個大的JSON字符串

{ 
    "list": { 
    "pagination": { 
     "count": 0, 
     "hasMoreItems": true, 
     "totalItems": 0, 
     "skipCount": 0, 
     "maxItems": 0 
    }, 
    "entries": [ 
     { 
     "entry": { 
      "id": "string", 
      "firstName": "string", 
      "lastName": "string", 
      "description": "string", 
      "avatarId": "string", 
      "email": "string", 
      "skypeId": "string", 
      "googleId": "string", 
      "instantMessageId": "string", 
      "jobTitle": "string", 
      "location": "string", 
      "company": { 
      "organization": "string", 
      "address1": "string", 
      "address2": "string", 
      "address3": "string", 
      "postcode": "string", 
      "telephone": "string", 
      "fax": "string", 
      "email": "string" 
      }, 
     } 
    ] 
    } 
}

我真正得到和要分析是，如果你想看看它，這個字符串（其中包含7「條目「）：

{"list":{"pagination":{"count":7,"hasMoreItems":false,"totalItems":7,"skipCount":0,"maxItems":100},"entries":[{"entry":{"lastName":"Beecher","userStatus":"Helping to design the look and feel of the new web site","jobTitle":"Graphic Designer","statusUpdatedAt":"2011-02-15T20:20:13.432+0000","mobile":"0112211001100","emailNotificationsEnabled":true,"description":"Alice is a demo user for the sample Alfresco Team site.","telephone":"0112211001100","enabled":false,"firstName":"Alice","skypeId":"abeecher","avatarId":"198500fc-1e99-4f5f-8926-248cea433366","location":"Tilbury, UK","company":{"organization":"Moresby, Garland and Wedge","address1":"200 Butterwick Street","address2":"Tilbury","address3":"UK","postcode":"ALF1 SAM1"},"id":"abeecher","email":"[email protected]"}},{"entry":{"firstName":"Administrator","emailNotificationsEnabled":true,"company":{},"id":"admin","enabled":true,"email":"[email protected]"}},{"entry":{"firstName":"Alex","lastName":"lol","emailNotificationsEnabled":true,"company":{},"id":"alexandra","enabled":true,"email":"[email protected]"}},{"entry":{"firstName":"Guest","emailNotificationsEnabled":true,"company":{},"id":"guest","enabled":false}},{"entry":{"firstName":"Jack","lastName":"lol","emailNotificationsEnabled":true,"company":{},"id":"jack","enabled":true,"email":"[email protected]"}},{"entry":{"lastName":"Jackson","userStatus":"Working on a new web design for the corporate site","jobTitle":"Web Site Manager","statusUpdatedAt":"2011-02-15T20:13:09.649+0000","mobile":"012211331100","emailNotificationsEnabled":true,"description":"Mike is a demo user for the sample Alfresco Team site.","telephone":"012211331100","enabled":false,"firstName":"Mike","skypeId":"mjackson","avatarId":"3fbde500-298b-4e80-ae50-e65a5cbc2c4d","location":"Threepwood, UK","company":{"organization":"Green Energy","address1":"100 Cavendish Street","address2":"Threepwood","address3":"UK","postcode":"ALF1 SAM1"},"id":"mjackson","email":"[email protected]"}},{"entry":{"firstName":"Nicolas","lastName":"lol","emailNotificationsEnabled":true,"company":{},"id":"nicolas","enabled":true,"email":"[email protected]"}}]}}

所以我的代碼來解析它是

<div id="liste"></div> 
<script> 
     var objet = JSON.parse('***[....Big string....]***'); 
     document.getElementById("liste").innerHTML = objet.firstName; 
</script>

所以我嘗試了很多組合，如objet.entries.entry.firstName或objet.entries的[1]（其中給我Uncaught TypeError: Cannot read property '1' of undefined）... 但我仍然不知道如何達到我的目標，例如獲取.firtName。而我只找到互聯網上的JSONparse（）的簡單例子，例如像這樣的字符串{"firstname":"Jesper","surname":"Aaberg","phone":"555-0100"} so ..

如果有人知道提前致謝！

So I tried a lot of combinations such as objet.entries.entry.firstName or objet.entries[1] (which gives me Uncaught TypeError: Cannot read property '1' of undefined)

JavaScript數組的第一個元素的索引0元素 - 所以你只是想：

var firstName = objet.list.entries[0].entry.firstName

這實際上給了我同樣的錯誤，我改'的document.getElementById（「清單當然」）.innerHTML = objet.entries [0] .entry.firstName;'我仍然得到'未捕獲的TypeError：無法讀取屬性'0'未定義的' – JackA

好的，謝謝，你是對的，它不是結構預計，我添加了「list」，它的工作原理是：'objet.list.entries [0] .entry.firstName'但是，爲了確保在將來的代碼中，我給出的例子不應該添加「list」？ – JackA

@JackA我想我實際上錯過了json中的'list'，而不是你。對不起， – Jamiec
