[Solved] nodejs – array search and append

by


Your objects initial value:

var myObj = [{'ABC': '5'}, {'BCD': '1'}]

Now if DDD doesn’t exists, just add it:

var DDD = "3"
var DDDExists = false;

myObj.forEach(function(){
  if(this.DDD.length > 0){
    // If it exists, break the loop
    DDDExists = true;
    break;
  }
})

// If DDD doesn't exists, add it
if(DDDExists === false){
  // Add DDD object to array
  myObj.push({'DDD': 3});
}

Now if ABC exists, sum ABC to all the available values:

// Check if ABC exists
var ABCExsits = false;

myObj.forEach(function(){
  if(this.ABC.length > 0){
    // If ABC exits, break the loop
    ABCExists = true;
   break;
  }
})

if(ABCExists === true){

  // Sum all the values
  var totalSum = 0;

  myObj.forEach(function(){
    // Since we don't know the name property of the obj, we need to do a for loop
    for(var prop in this){
      totalSum = totalSum + this[prop];
    }    
  })

  // Now add `totalSum` to ABC

  myObj.foreach(function(){
    if(this.ABC.length > 0){
      this.ABC = totalSum;
      break;
    }
  })

}
