JS event listener for a type of element?

Question

Is there a way to add some kind of listener for a type of html element? For example if i wanna call a function when the user clicks any p element

Answer 1

I assume that you are looking for code along these lines:

var paras = document.getElementsByTagName("p");

// Loop through elements. 
for(var i = 0; i < paras.length; i++) {
    // Add listener.
    paras[i].addEventListener("click",
        function() { 
            // Execute function.
        }, false);
}
