I found [this][1], rather difficult, javascript example online and I\'ve implemented it with success in my website.
However, I would like to get the result of, in th
Replace:
document.getElementById('total').value = parseInt(sum);
With:
document.getElementById('total').value = sum;
You have already done all the int-parsing you need to do.
$("#value1, #value2").on('focusout', function() {
var value2 = parseInt($("#value2").val()) > 0 ? parseInt($("#value2").val()) : 0;
var value1 = parseInt($("#value1").val()) > 0 ? parseInt($("#value1").val()) : 0
var sumOfValues = value1 + value2;
console.log('Your sum is ' + sumOfValues);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="text" class="input" id="value1">
<input type="text" class="input" id="value2">
Well, if you have assigned ID's to text inputs, for example: <input type="text" id="my_input" />, then you can call it with document.getElementById('my_input').value.
So:
<input type="text" id="my_input1" /> <input type="text" id="my_input2" /> <input type="button" value="Add Them Together" onclick="doMath();" /> <script type="text/javascript"> function doMath() { // Capture the entered values of two input boxes var my_input1 = document.getElementById('my_input1').value; var my_input2 = document.getElementById('my_input2').value; // Add them together and display var sum = parseInt(my_input1) + parseInt(my_input2); document.write(sum); } </script>
Naturally, that is a very basic script, it doesn't check to make sure the entered values are numbers. We have to convert the fields into integers, otherwise they'll be strings (so 2+2 would equal 22). When the button is clicked, the function is called, which makes a variable for each input box, converts them to ints, adds them, and outputs our sum.
