    Hard to see what you did wrong without the code. Our crystal balls are broken. Show sample input and expected output. Providing those details will result in a nice answer. Put effort into your question and people will put effort into the answers. Sounds like you need to check it is a number before you add. – epascarello Nov 20 '19 at 13:41

  • @DavidJawHpan for (var i = 0; i < strSplit.length; i++) { var sum = parseInt(sum) + parseInt(strSplit[i]) } document.getElementById("resultStr").value = sum; } – Ajay R Nov 21 '19 at 09:47

Try to find if the entered text is a number or not and then try to add them.

you can use below snippet.

It is just to give you the idea.

var ToCheck=sometext;
var  IsNotaNumber=isNaN(ToCheck);//check both the inputs
if(!IsNotaNumber)
{
//add the numbers
}
