Automatically move through anchors

I need a way to automatically/programmatically move through anchors on the homepage of a WordPress site. The anchor’s I want to move through are the tabs in the middle.

For example: page loads, waits specified time, tab 2 opens, waits specified time, tab 3 opens, waits specified time, tab 4 opens, and then keeps repeating. Once it gets to the end, I want it to go back to the beginning. Ideally it would stop on hover if mouse, but I haven’t tried to implement that yet.

I have tried to create a JavaScript program in the “text” part of the post showing on the homepage, but it doesn’t seem to work. I see the "Test" alert, but never see the "Hello" alert.

<script type="text/javascript">
function scrollTo(hash) {
    location.hash = "#" + hash;
    alert('Hello');
}
function tabSlider() {
    delay = 2000; //2 second delay
    setTimeout(function() {scrollTo(ert_pane1-1);},delay);
    setTimeout(function() {scrollTo(ert_pane1-2);},delay*2);
    setTimeout(function() {scrollTo(ert_pane1-3);},delay*3);
    setTimeout(function() {scrollTo(ert_pane1-4);},delay*4);
    setTimeout(function() {scrollTo(ert_pane1-0);},delay*5);
    tabSlider();
    alert('Test');
}
window.onload = tabSlider();
//-->
</script>

The plugin for the tabs is Easy Responsive Tabs.

Thanks to brasofilo, here is the final working code:

<script type="text/javascript">
function scrollTo(hash) {
    location.hash = "#" + hash;
    jQuery( "a[href='#" + hash + "']" ).click(); // finds <a> with href==hash and clicks
}
function tabSlider() {
    delay = 3000; //2 second delay
    setTimeout(function() {scrollTo('ert_pane1-1');},delay);
    setTimeout(function() {scrollTo('ert_pane1-2');},delay*2);
    setTimeout(function() {scrollTo('ert_pane1-3');},delay*3);
    setTimeout(function() {scrollTo('ert_pane1-4');},delay*4);
    setTimeout(function() { scrollTo('ert_pane1-0'); tabSlider(); }, delay*5 );
}
window.onload = tabSlider();
//-->
</script>

EDIT For those who want to know how I did my hover, I just used jQuery to prevent the click:

var hovering = 0;
jQuery ("#primary").hover(function() { hovering = 1; },
                  function() { hovering = 0; });
function scrollTo(hash) {
    if (hovering==1) {
    //Do nothing
    } else {
    location.hash = "#" + hash;
    jQuery( "a[href='#" + hash + "']" ).click(); // finds <a> with href==hash and clicks
    }
}
