Question

Sorry for asking, but how do I access myFunction() from someFunction()?

<script>
$(document).ready(function() {
    // Get messages
    var myFunction = function() {
      // doSth.
    }

    // Make the initial call on page load.
    myFunction();
);

function someFunction() {
    // Call the function a second time 
    myFunction();  // Call fails!
}
</script>

Its more then a scope issue. Yes, you are scoping it to the anonymous function but even if you make it global by removing the var like this:

$(document).ready(function() {
     // gets defined AFTER THE DOM IS READY
     myFunction = function() {
      // doSth.
     }
}

// is called BEFORE THE DOM IS READY
myFunction();

It STILL won’t work, because myFunction hasn’t been defined by the time you call someFunction. someFunction is running immediately before the document is ready, which is BEFORE myFunction is defined.

Both functions need to be either in the document ready block, or outside it. If you need to manipulate DOM elements, I’d recommend inside.

If someFunction is called for a handler, you can remove the var declaration from myFunction and it will work as expected, because this will put myFunction in the global scope.
