[Web4lib] Valid substitute for body onLoad()

Mon Oct 30 18:49:26 EST 2006

Simon Willison came up with the standard way to do this via a DOM
event handler. See if it solves the problem.

The actual code involved:

function addLoadEvent(func) {
  var oldonload = window.onload;
  if (typeof window.onload != 'function') {
    window.onload = func;
  } else {
    window.onload = function() {
      if (oldonload) {
        oldonload();
      }
      func();
    }
  }
}

addLoadEvent(nameOfSomeFunctionToRunOnPageLoad);
addLoadEvent(function() {
  /* more code to run on page load */
});
