javascript for dom ready function

Question

My visualforce page is

<apex:outputpanel>
 <apex:variable value="0" var="rowNum"/> 
      <apex:dataTable value="{!templook}" var="item" style="margin-left:60px;"  cellpadding="5" cellspacing="6"   >
 <apex:column headerValue="Quantity">
                      **<apex:inputtext Value="{!item.Quantity__c}" onblur="multiplycal();" styleclass="quantity{!rowNum}"/>**
                  </apex:column>
                   <apex:column headerValue="Unit Price($)">
                     <apex:inputtext Value="{!item.Price__c}" styleClass="price{!rowNum}" onblur="multiplycal();"/>
                  </apex:column>
  </apex:datatable>
           <input type="hidden" value="{!rowNum}" class="values" name="values"/>  
</apex:outputpanel>
 <apex:pageBlockSectionItem >          
                     <apex:outputLabel value="total($) :"/>
                     <apex:outputLabel value="" styleClass="sum"  style="width:78px;text-align:right;display:block;font-size:12px;color:#000000;" />
                     </apex:pageBlockSectionItem>      

My javascript is:

<script type="text/javascript">
var j$ = jQuery.noconflict();
function multiplycal(){
    var values=$(".values").val();  
    var total = 0.0;

    for(var i=0;i<values;i++)
    {
        var amtfield=trim($(".price"+i).val());       
        var quantity=trim($(".quantity"+i).val());
        total= parseFloat(total)+(parseFloat(amtfield) * parseInt(quantity));
    }

    alert(total);
    $('.sum').html(formatDoll(total));
}

function formatDoll(number) {
    var pip = number.toFixed(2).split(".");
    return pip[0].split("").reverse().reduce(function(acc, number, i, orig) {
        return  number+ (i && !(i % 3) ? "," : "") + acc;
    }, "") + "." + pip[1];
}
</script>

If I use apex:inputtext it is working fine. But my requirement is <apex:outputlabel Value="{!item.Quantity__c}" onblur="multiplycal();" styleclass="quantity{!rowNum}"/>. for this I can't use onblur since I'm using apex:outputlabel. Hence I should go with dom ready function.But don't have any idea.Help!!!!!!

Well not sure what you want to do but if you want to hook to the dom ready you have to do something like this

var j$ = jQuery.noconflict(); 
j$(document).ready(function() {
   // put all your js in here.
 });
