Getting javascript to play nice with other javascript can be a nightmare. When scripts have been written with a callback function using window.onload or an onload in the body tag, it can more often than not, break other scripts that are using it too. Below is the answer: function addLoadEvent(func) { var oldonload = window.onload; if (typeof window.onload != ‘function’) { window.onload = func; } else { window.onload = function() { if (oldonload) { oldonload(); } func(); } } } addLoadEvent(nameOfTheFunctionToRunOnPageLoad); addLoadEvent(function() { /* more code to run on page load */ });
