All the answers here discuss about onclick method, however you can also use addEventListener().

Syntax of addEventListener()

document.getElementById('button').addEventListener("click",{function defination});

The function defination above is known as anonymous function.

If you don't want to use anonymous functions you can also use function refrence.

function functionName(){
//function defination
}



document.getElementById('button').addEventListener("click",functionName);

You can add a click event handler for this   document getElementById  button   onclick   function        alert  button was clicked           This will alert when it s clicked  if you want to track it for later  just set a variable to true in that function instead of alerting  or variable   if you want to count the number of clicks  whatever your ultimate use is   You can see an example here

Try adding an event listener for clicks  document getElementById  button   addEventListener  quot click quot   function        alert  quot You clicked me quot           Using addEventListener is probably a better idea then setting onclick - onclick can easily be overwritten by another piece of code  You can use a variable to store whether or not the button has been clicked before  var clicked   false document getElementById  button   addEventListener  quot click quot   function        clicked   true        addEventListener on MDN
