In this blog i will show how to add two numbers with javascript. I have used parseInt function to convert the value from string to int.

Below is the sample code:

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title>Untitled Page</title>
</head>
<body>
    First Number :<input id="txtFirstNumber" type="text" /><br />
    Second Number:<input id="txtSecondNumber" type="text" />
    <input id="btnAdd" type="button" value="Add" onclick="sum();" />
</body>

<script type="text/javascript">

    function sum()
    {

        var txtFirstNumberValue = document.getElementById('txtFirstNumber').value;
        var txtSecondNumberValue = document.getElementById('txtSecondNumber').value;
        alert(parseInt(txtFirstNumberValue) + parseInt(txtSecondNumberValue));

    }
      
</script>

</html>
