Several ways to refresh the page using Javascript:

No refresh
2 location.reload()

Refresh
3 location=location
To navigate in javascript, instead of calling a method of the window object, set its location.href property , the location attribute is supported by every browser. For example:
<span onclick=”javascript:window.location.href=’#top’”>top</span>
