Keep focus on field after Save

Question

I'm using a visual force page with an extended controller. When I click on the 'Save Only' button the page reloads to the top. How can I keep the focus on the field that a user was on prior to saving ? I am using the save action on the standard controller, not the extended controller. Below is my javascript and visual force snippet where the command button is calling the functions.

Any ideas as to why the page does not scroll down to the last field where the cursor was ?

<script src="/soap/ajax/30.0/connection.js" type="text/javascript"></script>
<apex:includeScript value="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js" />
<apex:includeScript value="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js" />
<script>
    var fileldId;
    function oncfoucs(){
        debugger;
       fileldId = $(document.activeElement); 
    }
function focusComplete(){
    fileldId.focus();
}
</script>

<apex:outputPanel style="text-align:center" layout="block">
<apex:commandButton styleClass="myClass" action="{!save}" value="Save Only" />
<apex:commandButton styleClass="myClass" action="{!saveAndReturn}" value="Save and Return to Template" />
<apex:commandButton styleClass="myClass" action="{!ReturnMe}" value="Audit Template Screen" />
<apex:commandButton styleClass="myClass" action="{!save}" value="Save Test" onmouseover="oncfoucs();" oncomplete="focusComplete();" />

This will need some adept javascript programming. I'm hereby providing a high level solution, considering you will be able to implement the same.

1. You can create a String property in extension controller.
2. Bind this property with a hidden control "id = hdnFocusedElement" (let's say a text box) on VF Page.
3. For all controls (use jQuery for ease), add "onfocus" event handler, wherein the id of focued field will be set as value of hidden control "hdnFocusedElement"
4. Create a javascript which works on page load (jQuery will again help here), and check if there is any value in "hdnFocusedElement" element, then set focus of the id present in value of "hdnFocusedElement" element.
