使用javascript / Angular在JSONObjects中读取JSONOBjects

Question

{  
   "APPLICATION_DETAIL":[
    {  
         "Application1":"",
         "Application2":"",
         "status":{  
            "Application1":"Active",
            "Application2":"Inactive"
         },
         "modifiedBy":"a123453"
      },
      {  
         "Application1":"",
         "Application2":"W",
         "status":{  
            "Application1":"Inactive",
            "Application2":"Inactive"
         },
         "modifiedBy":"a123456"
      }  
   ]
}

在上面的JSON对象中，我试图检查两个应用程序的状态是否都处于非活动状态，如果是，我需要删除该对象，我现在正面临挑战甚至读取状态值，状态列表也是动态的它可以是一个值或多个值，任何帮助将不胜感激

Answer 1

以下是查找所有非活动应用程序索引的代码段：

＆＃13;

＆＃13;

var applications = {  
   "APPLICATION_DETAIL":[
    {  
         "Application1":"",
         "Application2":"",
         "status":{  
            "Application1":"Active",
            "Application2":"Inactive"
         },
         "modifiedBy":"a123453"
      },
      {  
         "Application1":"",
         "Application2":"W",
         "status":{  
            "Application1":"Inactive",
            "Application2":"Inactive"
         },
         "modifiedBy":"a123456"
      }  
   ]
}

applications = applications.APPLICATION_DETAIL;
var applicationsNumber = applications.length;
var objectsToRemove = [];

for(var appIndex = 0; appIndex < applicationsNumber; appIndex++) {
	var application = applications[appIndex];
	var isActive = false;;
	
	var statuses = Object.keys(application.status);
	var statusesNumner = statuses.length;
	
	for(var statusIndex = 0; statusIndex < statusesNumner; statusIndex++) {
		if(application.status[statuses[statusIndex]] === 'Active') {
			isActive = true;
		}
	}
	
	if(!isActive) {
		objectsToRemove.unshift(appIndex);
	}
}

console.log(objectsToRemove);

var removeObjectsNumber = objectsToRemove;
for(var removeIndex = 0; removeIndex < removeObjectsNumber; removeIndex++) {
  applications = applications.splice(removeIndex, 1);
}

console.log(applications);

首先，我将打印您的申请状态：

  

复制此代码并在浏览器控制台

中运行

void readResource(InputStream source) throws IOException {
    BufferedReader stream = null;
    try {
        stream = new BufferedReader(new InputStreamReader(source));
        while (true) {
            String line = stream.readLine();
            if(line == null) {
                break;
            }
            //process line
            System.out.println(line)
        }
    } finally {
        closeQuiet(stream);
    }
}

static void closeQuiet(Closeable closeable) {
    if (closeable != null) {
        try {
            closeable.close();
        } catch (IOException ignore) {
        }
    }
}

的

现在您可以在其中添加 if 条件并执行操作
