HI.. I am unable get and set the values for a visualforce page in Controller class. I have the below visualforce code.

<apex:pageBlockTable value="{!ords}" var="a" id="detailTable">
<apex:column headerValue="Item Name">
<apex:inputField id="itemId" value="{!a.Item__c}" onblur="setItemName();"/>
<apex:inputHidden id="itemNameId" value="{!itemNameId}"/>
</apex:column>
<apex:column headerValue="Price">
<apex:inputField id="priceId" value="{!a.Price__c}" onblur="setItemPrice();"/>
<apex:inputHidden id="itemPrice" value="{!itemPrice}"/>
</apex:column>

</apex:pageBlockTable>

 I am setting the values for itemNameId and itemPrice in javascript. Below is the code for that.

<script>
function setItemName(){
//alert('Before setting the setItemName');
for(i=0; i<100; i++) {
document.getElementById('soPage:theForm:blockId:detailTable:'+i+':itemNameId').value = document.getElementById('soPage:theForm:blockId:detailTable:'+i+':itemId').value;
}
}
function setItemPrice(){
for(i=0; i<100; i++) {
document.getElementById('soPage:theForm:blockId:detailTable:'+i+':itemPrice').value = document.getElementById('soPage:theForm:blockId:detailTable:'+i+':priceId').value;
}
}
</script>

Also am setting the values for these fields in Controller class like below.

    public String itemNameId {get;set;}
    public String itemPrice {get;set;}

But my problem is that unable to get the values for those fields in Controller. 

Please let me know how I can achieve the same problem.

Thanks in advance.
