Making a calculator in JavaScript is not have been taught so far.As it supports mathematical calculations. With the help of JQuery, HTML and CSS we can build few tiny applications which run completely inside the browser.
In this tutorial, we will learn how to create a simple calculator using the jQuery javascript library. But first, we must understand the requirements in building a javascript driven application. One of the requirements is your thorough understanding in HTML (Hypertext Markup language) and in CSS (Cascading Stylesheet). These languages are required in building the graphic user interface (GUI) of the application.
What we expect in the GUI is a two textboxes for inputting of numbers, a combobox for selection of the desired operator, 1 container for the output and of course the trigger through a submit button. The code goes like this:
2 4 6 8 10 12 14 | <h3>Simple Calculator</h3> <select id='ope'> <option value='+'>+</option> <option value='x'>x</option> </select> <input type='submit'value='Answer'> </form> |
After building the html code for the simple calculator application, modify the look and feel of the form elements through CSS.
2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 | body { } background:#69aafd; padding:11px; text-align:center; text-align:center; #calculator_form { width:100%; padding:5px; } display:inherit; padding:13px; font-size:25px; #calculator_form #answer { color:#FF0000; text-align:right; </style> |
We can now put the jQuery code for our simple calculator application.
