Easiest HTML Calculator Eample Code

Easiest Calculator Code Eample

There are plenty of ways to do math on a desktop computer using a built-in calculator, but another way is to build one yourself using a simple HTML code. To create a calculator using HTML, learn some basics about HTML, then copy the necessary code into a text editor and save it with an HTML extension. You can then use your calculator by opening up the HTML document in your favorite browser. By doing all of this, not only will you be able to do math in a browser, but you can also learn some fundamentals about the art of coding!

Coding Your Calculator

1. Copy the code below. Highlight the text in the box below by holding down your cursor in the top-left corner of the box, and dragging it to the bottom-right corner of the box so that all of the text is blue. Then, press "Command+C" on a Mac or "Ctrl+C" on a PC to copy the code the clipboard.

<html>
<head>
<title>HTML Calculator</title>
</head>
<body bgcolor= "#000000" text= "gold">
<form name="calculator" >
<input type="button" value="0" onClick="document.calculator.ans.value+='0'">
<input type="button" value="1" onClick="document.calculator.ans.value+='1'">
<input type="button" value="2" onClick="document.calculator.ans.value+='2'">
<input type="button" value="3" onClick="document.calculator.ans.value+='3'">
<input type="button" value="4" onClick="document.calculator.ans.value+='4'"><br />
<input type="button" value="5" onClick="document.calculator.ans.value+='5'">
<input type="button" value="6" onClick="document.calculator.ans.value+='6'">
<input type="button" value="7" onClick="document.calculator.ans.value+='7'">
<input type="button" value="8" onClick="document.calculator.ans.value+='8'">
<input type="button" value="9" onClick="document.calculator.ans.value+='9'"><br />
<input type="button" value="-" onClick="document.calculator.ans.value+='-'">
<input type="button" value="+" onClick="document.calculator.ans.value+='+'">
<input type="button" value="*" onClick="document.calculator.ans.value+='*'">
<input type="button" value="/" onClick="document.calculator.ans.value+='/'">
<input type="button" value="=" onClick="document.calculator.ans.value=eval(document.calculator.ans.value)"><br />
Solution is <input type="textfield" name="ans" value=""><br />
<input type="reset" value="Reset">
</form>
</body>
</html>

2. Open a text editing program on your computer. There are a number of programs you can use, but for convenience and quality, we recommend using TextEdit or Notepad.

On a Mac, click on the magnifying glass at the top-right corner of your screen to open Spotlight. Once there, type in TextEdit and click on the TextEdit program, which should now be highlighted in blue.

On a PC, open the Start menu at the bottom-left corner of your screen. In the search bar, type Notepad and click on the Notepad application, which will appear in the results bar to the right.

3. Paste the HTML code for a calculator into the document.

On a Mac, click on the body of the document and press "Command+V". You will then need to click on "Format" at the top of your screen and click "Make Plain Text" after pasting the code.

On a PC, click on the body of the document and press "Ctrl+V".

4. Understand what each html function is doing. The code you will use to create your calculator is made up of many pieces of syntax that work together to define different elements of a document. Click here for an explanation of how to familiarize yourself with this process, or read on to learn what each line of text is doing in the code you'll be using to make your calculator.

html: This piece of syntax tells the rest of the document what language is being used in the code. In coding, a number of languages used to code, and <html> tells the rest of the document that it will be in - you guessed it! - html.

head: Tells the document that everything beneath it is data about data, also known as "metadata". The <head> tag is usually used to define stylistic elements of a document, such as titles, headings, and so on. Think of it as an umbrella under which the rest of the code is defined.
