iterating over an array while copying only integers to another in js

Question

I have tried iterating over the array holder2 while copying it's integer elements to another array temp . But it doesn't seem to work as the content of temp remained the same.

var holder=getElementById("userinput").value;
var holder2=holder.split(" ");
var temp =[];

for(vari=0;i<holder2.length;i++){
  if(isNaN(holder2[i])===false){
    temp[i]=holder2[i];
  }
}

Answer 1

That's not how you add an element to an array in Javascript. What you're looking for is push() .

temp.push(holder2[i]);

Answer 2

You mentioned that you want integers only and that temp is empty. I'd suggest verifying that elements are integers and then using Array.push() .

var holder=getElementById("userinput").value;
var holder2=holder.split(" ");
var temp =[];

for(var i=0;i<holder2.length;i++){
  if(isNaN(holder2[i])===false && holder2[i] % 1 === 0){
    temp.push(holder2[i]);
  }
}

Answer 3

Try this:

var holder=getElementById("userinput").value;
var holder2=holder.split(" ");
var temp =[];

for(var i=0;i<holder2.length;i++){
    var num = parseInt(holder2[i])
    if(isNaN(num)===false){
        temp.push(num)
    }
}
