How to Change Text on Offset Pages?

<script type = "text/javascript">  
window.onload = function () {  
document.getElementById("h1").innerHTML = "More Posts";  
}  
</script>

I wanted to know how I would go about changing the "Recent Posts" text to "More Posts" on all offset pages? I was wondering how I could modify the above javascript to make it happen.
