Why is this javascript function running without being called?

Question

$(document).ready(SetupButtonClicks());

function SetupButtonClicks() {
    $(\'#btnJavaPHP\').click(DoPHPStuff());
}

function DoPHPStuff() {
    //stuff
}
<         


        

Answer 1

With the exception of a function declaration, a pair of parentheses following a function's identifier causes the function to execute. Examples:

// function declaration; function not executed
function SetupButtonClicks() {

}

// function executed
SetupButtonClicks();

// function not executed
SetupButtonClicks;
