does anyone know how to set up a button that increases count every time it's click?

I will show you the code first, then i will try to explain how it works

Here is the HTML

   <button id="btn">You have clicked this button <span id="btn-counter"></span></button>

Basic HTML5

Here is the Javascript

 // the button
 var btn = document.getElementById("btn");

 // the counter
 var counter = document.getElementById("btn-counter");

 // set the counter to 0
 counter.innerHTML = 0;

 // increment the counter by 1 everytime the user clicks on the button
 btn.onclick = function()
 {
    counter.innerHTML++;
 };

The btn variable in the javascript code contains the HTML button object.

The counter in the javascript code contains the counter that will be incrementing every time you click. In this case the counter is the HTML <span id="btn-counter"></span> object.

we then set the btn_counter to 0

when the make the counter increment by 1 everytime we click on it by using the ++ operator on the counter.innerHTML variable.

I tried my best to explain this to you, I hope you understood. Good Luck !
