Traversing an array of objects to locate a specific key

Question

Traversing an array of objects to locate a specific key

I have an array of objects structured as follows:

data = 
[
  {
    "AccountType":"Client",
    "DeploymentList":
      {
        "-L3y8Kpl5rcvk-81q004":
        {
          "DeploymentKey":"-L3y8Kpl5rcvk-81q004",
          "DeploymentName":"Testing 3"
        }
      }
  },
  {
    "AccountType":"Client",
    "DeploymentList":
      {
        "-L3yGFxXQ8XbeK8b2GSF":
        {
          "DeploymentKey":"-L3yGFxXQ8XbeK8b2GSF",
          "DeploymentName":"Testing 1"

        }

      }
  }
]

I am attempting to loop through this data in order to find a specific string. The goal is to locate https://i.sstatic.net/F6w81.png

My current approach involves the following code snippet:

for (let d of this.data) {
      for(let a of d.DeploymentList){
        if(a.$key==="-L3y8Kpl5rcvk-81q004"){
          // Inside the condition
    }
}

Unfortunately, this method is not yielding the desired results. Any suggestions on how I can successfully accomplish this task?

Answer №1

To verify the presence of a key, you can use the following code snippet:

for (let item of this.entries) {
      for(let subItem of item.subEntries){
        if(subItem["-F6z2Nqo9fbzc-11s903"]){
          // Code executed when condition is met
    }
}

Deciding on the next step depends on your specific goal. If you are aiming to locate a particular item in the deployment list, using the find function is the way to go.

var item = data.find(item => item.DeploymentList["-L3y8Kpl5rcvk-81q004"]);

This code snippet will fetch the item from the data array that corresponds to the specified DeploymentList item.

var data = 
[
  {
    "AccountType":"Client",
    "DeploymentList":
      {
        "-L3y8Kpl5rcvk-81q004":
        {
          "DeploymentKey":"-L3y8Kpl5rcvk-81q004",
          "DeploymentName":"Testing 3"
        }
      }
  },
  {
    "AccountType":"Client",
    "DeploymentList":
      {
        "-L3yGFxXQ8XbeK8b2GSF":
        {
          "DeploymentKey":"-L3yGFxXQ8XbeK8b2GSF",
          "DeploymentName":"Testing 1"

        }

      }
  }
];

var item = data.find(item => item.DeploymentList["-L3y8Kpl5rcvk-81q004"]);
console.log(item);
