Find items from json array using NodeJS

Question

Am trying to search for particular items from a JSON array and return the items...

 result = {
      FF: {
        server: 'deskes.com',
        result: 'succes'
    
      },
         {
        server: 'cleantarge.com',
        result: 'Failed'
    
      },
         {
        server: 'fance34.com',
        result: 'success'
    
      },{
        server: 'deskes.com',
        result: 'Failed'
    
      },
    
    }

I have following JSON data. I want to search items based on server

I used the code

var arrFound = result.filter(function(item) {
    return item.server == 'deskes.com';
});

But getting TypeError: Object #<Object> has no method 'filter'

my resulting JSON after searching the data will be:

result = {
  FF: {
    server: 'deskes.com',
    result: 'succes'

  },

  {
    server: 'deskes.com',
    result: 'Failed'

  }

}

You also can use the arrow function version of ECMAScript 2015:

rta =  result.filter(it => it.server === 'deskes.com');

The code:

var result = [
  {
   server: 'deskes.com',
    result: 'succes'

  },
     {
    server: 'cleantarge.com',
    result: 'Failed'

  },
     {
    server: 'fance34.com',
    result: 'success'

  },{
    server: 'deskes.com',
    result: 'Failed'

  }
];



var rta =  result.filter(it => it.server === 'deskes.com');

console.log(rta);

/*
Result:

[
  {
    "server": "deskes.com",
    "result": "succes"
  },
  {
    "server": "deskes.com",
    "result": "Failed"
  }
]

*/

The filter method is only available on arrays, and it looks like you're calling it on an object (from the outer bracket). You can work around this by looping through the keys:

var arrFound = Object.keys(result).filter(function(key) {
    return result[key].server == 'deskes.com';
// to cast back from an array of keys to the object, with just the passing ones
}).reduce(function(obj, key){
    obj[key] = result[key];
    return obj;
}, {});;

I believe the problem is with your json, it needs to be an array.

Here is a code sample I have tested and it works fine.

var result = [
  {
   server: 'deskes.com',
    result: 'succes'

  },
     {
    server: 'cleantarge.com',
    result: 'Failed'

  },
     {
    server: 'fance34.com',
    result: 'success'

  },{
    server: 'deskes.com',
    result: 'Failed'

  }
];

var arrFound = result.filter(function(item) {
  return item.server == 'deskes.com';
});

console.log(arrFound);

// Outputs: [ { server: 'deskes.com', result: 'succes' }, { server: 'deskes.com', result: 'Failed' } ]
