Question

我有来自Atlassian Jira的未分类的JSON数据，该数据是我通过GET-request获得的：

[
   {
      "id":"customfield_10000",
      "name":"Konzeption",
      "custom":true,
      "orderable":true,
      "navigable":true,
      "searchable":true,
      "clauseNames":[
         "cf[10000]",
         "Konzeption"
      ],
      "schema":{
         "type":"number",
         "custom":"com.atlassian.jira.plugin.system.customfieldtypes:float",
         "customId":10000
      }
   },
   {
      "id":"priority",
      "name":"Priority",
      "custom":false,
      "orderable":true,
      "navigable":true,
      "searchable":true,
      "clauseNames":[
         "priority"
      ],
      "schema":{
         "type":"priority",
         "system":"priority"
      }
   },
   {
      "id":"customfield_10001",
      "name":"Umsetzung",
      "custom":true,
      "orderable":true,
      "navigable":true,
      "searchable":true,
      "clauseNames":[
         "cf[10001]",
         "Umsetzung"
      ],
      "schema":{
         "type":"number",
         "custom":"com.atlassian.jira.plugin.system.customfieldtypes:float",
         "customId":10001
      }
   }
]

我只想拥有每个“ customfield _ #####”的“ id”。如何搜索JSON以获取每个自定义字段的每个ID？

Answer 1

您可以使用forEach（function）枚举数组中的每个子节点！ //假设您的数据在一个数组中（正如您所提到的！） yourData.forEach（processEachNodes）; //由于ForEach是数组的函数，因此您只能 //如果您的数据是数组，请使用它，幸运的是，它是

function processEachNodes(myNode, index, rawObject){
    if(myNode.id.indexOf("customfield_") === 0){
        //DO SOMETHING HERE
    }
}

在获得子节点之后，无论您想要什么条件，您都可能知道如何处理这些ID。

因为您尚未定义编程语言，所以我会用不同的语言为她提供一些示例，希望对您有所帮助。

第一个PHP：

<?php
$j ='[
{
    "id":"customfield_10000",
    "name":"Konzeption",
    "custom":true,
    "orderable":true,
    "navigable":true,
    "searchable":true,
    "clauseNames":[
        "cf[10000]",
        "Konzeption"
    ],
    "schema":{
        "type":"number",
        "custom":"com.atlassian.jira.plugin.system.customfieldtypes:float",
        "customId":10000
    }
},
{
    "id":"priority",
    "name":"Priority",
    "custom":false,
    "orderable":true,
    "navigable":true,
    "searchable":true,
    "clauseNames":[
        "priority"
    ],
    "schema":{
        "type":"priority",
        "system":"priority"
    }
},
{
    "id":"customfield_10001",
    "name":"Umsetzung",
    "custom":true,
    "orderable":true,
    "navigable":true,
    "searchable":true,
    "clauseNames":[
        "cf[10001]",
        "Umsetzung"
    ],
    "schema":{
        "type":"number",
        "custom":"com.atlassian.jira.plugin.system.customfieldtypes:float",
        "customId":10001
    }
}
]';
$j = json_decode($j);
foreach($j as $o){
    echo (strpos($o->id, "customfield_")!==false)?'ok':'none';
}

现在的Javascript：

var j = '[{"id":"customfield_10000","name":"Konzeption","custom":true,"orderable":true,"navigable":true,"searchable":true,"clauseNames":["cf[10000]","Konzeption"],"schema":{"type":"number","custom":"com.atlassian.jira.plugin.system.customfieldtypes:float","customId":10000}},{"id":"priority","name":"Priority","custom":false,"orderable":true,"navigable":true,"searchable":true,"clauseNames":["priority"],"schema":{"type":"priority","system":"priority"}}, {"id":"customfield_10001","name":"Umsetzung","custom":true,"orderable":true,"navigable":true,"searchable":true,"clauseNames":["cf[10001]","Umsetzung"],"schema":{"type":"number","custom":"com.atlassian.jira.plugin.system.customfieldtypes:float","customId":10001}}]';
    j = JSON.parse(j);
    for(o in j){
        console.log ((j[o].id.indexOf("customfield_")>=0)?'ok':'none');
    }

如果您需要更多示例，请随意发表评论。
