Sorry,
Can you try this :

function showPage(pageURL,button_id) {
if (pageURL.substring(0,4).toLowerCase()=='http') {
window.open(pageURL, '_blank');
return;
};
hideContent(pageURL);
if ((selected_button!="" ) && button_id!=selected_button) {
sendToASUnselectButton('anim_'+selected_button);
}
if (button_id!=undefined) {
selected_button = button_id;
}
}
