How to Embed an Embed Calculator in a WordPress Website

It is pretty common for people to use online calculators in their daily lives. People who use them regularly may even feel that they are missing out on something by not having access to an offline version! An online calculator can be really convenient when you want to do some quick calculations (e.g. during a workout) or when you are doing your homework. You can even use online calculators to solve complicated problems, like finding the area of a polygon or the volume of a box. We will show you how to embed an online calculator on your WordPress website so that users can get all the benefits of using one.

What Is an Embed Calculator?

An embedded calculator is a small JavaScript program that is run directly inside a web browser when a user clicks a button or enters a search term in a web form. Embedded calculators usually take the form of small interfaces that are integrated into a form or a button so that users can enter a calculation at the tap of a button. They usually do not have an indicator of their own (e.g. a green tick or cross or something similar), but they may depend on the state of the surrounding form fields for their input.

These programs can be really small. The majority of them do not even need to have an icon or an indication that they exist. An example of an embedded calculator is the one used in the WordPress online store. When a user clicks the calculate button in the shopping cart, a small JavaScript window will appear with all the necessary form fields for the cart item’s subtotal and shipping fees. The button’s label is even replaced by the word “Calculate” as a visual indicator that the user is expected to click it to make a purchase and for it to reveal its secrets.

Why Would You Want to Embed an Embed Calculator?

Embedding a calculator simplifies many things for a web developer or designer. First of all, it can be really handy to have a small calculator in your browser that you can use for all sorts of things. You can make use of online calculators, but having an embedded version inside your site lets you take advantage of all that functionality even when you are offline. It also makes it easier to create a digital nomad lifestyle and to bring your work with you wherever you go. There are many great reasons why you might want to include an embedded calculator in your website.

How Do You Embed an Embed Calculator?

To get started, you will need to head over to GitHub and search for the WordPress repository. Once you have found it, you can navigate to the directory that contains the files for your project. Open up the index.html in your favorite text editor. You will see a single form field and a button. Above the form field, you will see the following code:

<button type="submit" class="submit" value="Submit">

This is the beginning of the form. Everything that follows it will be displayed inside a small window when the form is submitted. You can delete everything between the opening and closing <form> tags. Then, you will have to add some JavaScript code so that the form can be submitted when clicked. To do this, you will need to add the following code just above the closing <form> tag:

(function() {
     // Your JavaScript code goes here

This code will be wrapped in a script tag. You may also choose to use the more conventional </script> tag.

Make Sure That Your Calculator Is Up To Date

It is important to keep in mind that all embedded calculators are not created equal. Some of them are very basic, while others are incredibly sophisticated. The last thing you want to do is use an outdated calculator that does not have the features that you need or want. Before you start coding, it is a good idea to go to the developer’s website for the program that you will be using and make sure that it is the latest version. Doing this keeps all of your information up to date and ensures that you are not plagued by security issues. If you are not sure which version is the latest one, look for the largest number next to the word “Download”. This is usually the version that is currently supported by the developer.

Start Programming!

You will need to start by adding more form fields to your form. Above the button, you will see a series of asterisks (***). You will want to add a label for each field, but you do not have to make them all the same. You will also need to add a field for each number that the calculator may need to display. For example, if you are using the classic scientific calculator, you will need to add an input for every digit (0-9) as well as the decimal point. You can use the following basic structure for your input fields:

<input type="text" id="id_1" name="name_1" value="value_1" />
<input type="text" id="id_2" name="name_2" value="value_2" />
<input type="text" id="id_3" name="name_3" value="value_3" />
<input type="text" id="id_4" name="name_4" value="value_4" />
<input type="text" id="id_5" name="name_5" value="value_5" />
<input type="text" id="id_6" name="name_6" value="value_6" />
<input type="text" id="id_7" name="name_7" value="value_7" />
<input type="text" id="id_8" name="name_8" value="value_8" />
<input type="text" id="id_9" name="name_9" value="value_9" />

Notice that the “value” field is repeated for each number input field. This is because you are going to be using JavaScript to post the values, so you do not have to worry about duplicate input fields. Once you have added all the form fields, you will need to add a final input field for the “Submit” button. You will want to label this field as “submit” as well. Above the button, you will see the following code:
