You need parenthesis for calling the function. Otherwise you return the function itself, like in example 2.

<a onclick="foo[0]()" >Alert</a>
<!--              ^^         -->


var foo = [
    function() { alert("Function 1!"); },
    function() { alert("Function 2!"); }
];
<a onclick="foo[0]()" >Alert</a><br>
<a onclick="alert(foo[0])" >Alert, what really happens without parenthesis</a>

you should call the function . since you are getting only function using foo[0] . you need to call them by () to run the function 

var foo = [
  function() { alert("Function 1!"); },
  function() { alert("Function 2!"); }
];
foo[0]();
foo[1]();
