Today I will tell you how you can gst calculate by javascript code. The full form of GST is Goods and Services Tax.
Today I will tell you how to create a gst calculator by javascript code. First of all, you create an html form, add 3 text field and 1 button. For this you can see in the example mentioned below.
<html> <head> <title>How to Create GST Calculator using Javascript</title> </head> <body> <div> <label for="price">Price (before GST): </label> <input id="price" type="number" value="1" /> </div> <div> <label for="gst">GST rate (%): </label> <input id="gst" type="number" value="0.6" /> </div> <div> <button onclick="inpChange()">Calculate</button> </div> <div> <label for="priceGst">Price (GST inclusive) : </label> <input id="priceGst" type="number" readonly /> </div> </body> </html>
Then after that you write script code for gst calculation, for example you can see the script code given below.
<script>
priceEle = document.getElementById("price");
gstEle = document.getElementById("gst");
priceGstEle = document.getElementById("priceGst");
function calculateGst(price, tax) {
return (price * tax/100) + price;
}
function inpChange() {
if(!isNaN(priceEle.value) && !isNaN(gstEle.value)) {
price = Number(priceEle.value);
gst = Number(gstEle.value);
priceGstEle.value = calculateGst(price, gst).toFixed(3);
}
}
inpChange();
</script>
You can add whole code to gst-calculator.html by creating a file.

priceEle = document.getElementById("price");
gstEle = document.getElementById("gst");
priceGstEle = document.getElementById("priceGst");
function calculateGst(price, tax) {
return (price * tax/100) + price;
}
function inpChange() {
if(!isNaN(priceEle.value) && !isNaN(gstEle.value)) {
price = Number(priceEle.value);
gst = Number(gstEle.value);
priceGstEle.value = calculateGst(price, gst).toFixed(3);
}
}
inpChange();
