       function functn() {
           var a = document.getElementById('text1').value;
           var b = document.getElementById('text2').value;
           if (a == "")
               a = 0;
           if (b == " ")
               b = 0;

           var res = parseInt(a) + parseInt(b);

document.getElementById('text3').value = res;

</script>

<input type="text" value="text1">
<input type="text" value="text2" onblur="functn()" >
<<input type="text" value="text3" ></input>
