Question

I have two javascript text boxes.

<input type="text" name="test" value="300" />
<input type="text" name="test" value="500" />

How can I use javascript to alert the total price of the items in the text box?

Would something like this work?

var price = document.getElementById("test");
alert(price)

Answer 1

This will take all input elements into account (useful if you have many). Filter them by type and get their values in loop:

var inputs = document.getElementsByTagName("input");
var total = 0;

for (var i = 0; i < inputs.length; i++){
    if (inputs[i].type = "text"){
        total += parseInt(inputs[i].value, 10);
    }
}

alert(total);
