Character Counter with HTML and JS

Create a simple character counting system.

[clique aqui para português]

When we are working with text it is sometimes necessary to know how many characters the text has, or how many words. recently i needed something similar and after using some online tools i thought it would be interesting to create my own character counter, and that is what we are going to do.

CODE

First we will create the interface, we will do something simple, using only HTML.

HTML code

The HTML structure used oninput, an event that is triggered whenever we have a new data entry.

Now let’s create the countText function.

JS code

There, it’s that simple.

Demo
