Question

This works in Drupal 7:

jQuery(document).ready(function myfunction($) {
});

But what is the syntax for $(window).load?

This seems not to work:

jQuery(window).load(function myfunction($) {
});

Answer 1

You could try:

jQuery(window).bind('load', function() {
  // Function code
});

Edit to add example of Drupal jQuery noConflict code:

;(function($) {
  $(window).bind('load', function() {
    // Function code
  });
})(jQuery);

Update: Also changed erroneous myFunction to the proper function keyword.
