Plus Arithmetic Operation

Question

I\'ve tried use Plus Arithmetic Operation to calculate 2 input text type number values, but my result was the values are \"together\", like that:

Answer 1

parseInt is what missing from your code .. you need to parse it as integer barring which just the concatenation operation takes place , so you can either do this

var plus = parseInt(document.getElementById('plus').value, 10),
plus1 = parseInt(document.getElementById('plus1' ).value, 10);

or

var x = parseInt(plus , 10) + parseInt(plus1 , 10) ;
