How can I make a function which executes on page loading?

I have a JS function that I need to execute it when page loads. Here is the function:

function myfunc(){
    alert('something');
}

Noted that I also need to have a name for it. Because I need to call it after page loading again (on click of a element).

So in short, I need to define a function which executes both on page loading and when user click on $('.myclass') element. How can I do that?

how about <body onload="myfunc()"> and your function in the <head> element:

<script>
function myfunc(){
    alert('something');
}
</script>

and then to call it from button 

<button onclick="myfunc()">Click me</button>

Try below code, It calls Click me on load and on button click as well. Hope this helps

$(document).ready(function() {
  console.log('document load')
  clickMe();
});
$('.button').click(function(){
clickMe();
});
function clickMe(){
  console.log('Clicked');
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="button" > click me</button>

Put the call to that function in both the click handler for the .myclass elements, and also directly in a script tag, right before the </body>. Something like this:

<script>
    $(function() {
        $('.myclass').click(myfunc); // on click
    });

    myfunc(); // on load
</script>
