I have an element where I need to remove a percentage of it.
I've stored the original price as a variable and have another variable to work out the price after the percentage has been taken.
Here's the HTML:
<div class="price">420.29</div>
I want to remove 8% off .price
and have it fixed to two decimal places and store it as a variable.
Here's the JS I have so far:
var price = $(".price").html();
var priceafter = Math.round(price - price * 8 / 100).toFixed(2);
priceafter
returns back as 387.00 instead of 386.66.
Thanks to @datasage for point out I was using Math.round
. This is what I've changed it to and it seems to be working:
var price = $(".price").html();
var priceafter = (price - price * 8 / 100).toFixed(2);

Using Math.round
will round your result to the nearest whole number. You can used just toFixed
Which will round it correctly to 386.67
