how can i get total of two numbers using javascript
Question
I'm using this form script to automatically calculate totals. Now I need to get that total and print it. Here is my code.
function myFunction() { var x = document.getElementById("frm1"); var txt1 =x.elements[0].value; var txt2 =x.elements[1].value; var total =txt1+txt2; document.getElementById("demo").innerHTML="total is :"+total; }
<body> <form id="frm1"> First value : <input type="text" name="first"><br> Second Value : <input type="text" name="second"><br> </form> <p id="demo"></p> <button onclick="myFunction()"> ADD </button> </body>

It doesn't really say, but I'm guessing you're talking about numbers, if so parse the string values as numbers before you add them up
function myFunction() {
var x = document.getElementById("frm1");
var txt1 = parseFloat( x.elements[0].value );
var txt2 = parseFloat( x.elements[1].value );
var total = txt1 + txt2;
document.getElementById("demo").innerHTML = "total is :"+total;
}
