Get/Set value of field in PageBlockTable

I have a pageBlockTable in a visualforce page, in the table i am allowing users via JQuery .sortable to rearrange the order of the rows.

No, i want to store this sorting on page save, so i have created a new parameter on the product in Salesforce called sort_order that is a number field.

I would like to update the field, which is in the table and will eventually be hidden each time the rows are dragged, so that on save everything is stored.

I have the following code, which i am trying to get to loop through the table and update the fields appropriatley, but i can't work out the JQuery syntax for setting the value of the field.

Here is the code that creates the table:

            <apex:pageBlock title="Selected {!$ObjectType.Product2.LabelPlural}" id="selected">
                <apex:variable value="{!1}" var="index"> 
                <apex:pageblockTable value="{!shoppingCart}" var="s" id="shopping_cart" rowClasses="cartRow">
                    <tr data-SFid="{!index}">
                   
                   
                    <apex:column headerValue="{!$ObjectType.OpportunityLineItem.Fields.Description.Label}">
                        <apex:inputField id="item_description" value="{!s.Description}" required="false"/>
                    </apex:column>
                   
                   
                   
                    <apex:column headerValue="Current ID">
                    <apex:inputField id="Current_ID" value="{!s.Sort_Order__c}" style="width:70px" required="false" onkeyup="refreshTotals();"/>
                    </apex:column>
                   
                    <apex:column headerValue="Updated ID" value="{!index}" />
                   
                    <apex:column >
                        <apex:commandLink value="Remove" action="{!removeFromShoppingCart}" reRender="selected,searchResults" immediate="true">
                            <!-- this param is how we send an argument to the controller, so it knows which row we clicked 'remove' on -->
                            <apex:param value="{!s.PriceBookEntryId}" assignTo="{!toUnselect}" name="toUnselect"/>
                        </apex:commandLink>
                        <apex:variable value="{!index+1}" var="index">
                        </apex:variable>
                    </apex:column>
                   
                    <apex:column headerValue="{!$ObjectType.Product2.LabelPlural}" value="{!s.PriceBookEntry.Product2.Name}"/>
                   
                   
                                       
                   
                    <apex:column headerValue="{!$ObjectType.OpportunityLineItem.Fields.Quantity.Label}">
                        <apex:inputField value="{!s.Quantity}" style="width:70px" required="true" onkeyup="refreshTotals();"/>
                    </apex:column>
                   
                    <apex:column headerValue="{!$ObjectType.OpportunityLineItem.Fields.UnitPrice.Label}">
                        <apex:inputField value="{!s.UnitPrice}" style="width:70px" required="true" onkeyup="refreshTotals();"/>
                    </apex:column>
                   
                   
                   </tr> 
                </apex:pageblockTable>
                </apex:variable>

It is the "Current ID" editable field, with the ID of Current_ID that i want to update.

And this is as far as i have gotten with the update script, i have it looping through the rows with the "Selected" id, but i'm not sure how to update/access the value.

    $( "[id$=shopping_cart] tbody" ).sortable({
                        update: function(event, ui) {
                        //init();
                        i = 0;
                        $("[id$=shopping_cart] tbody tr.cartRow").each(function() {
                              $this = $(this)
                              var value = $(this).find('Current_ID');
                              var value2 = $(value).find('value');
                              console.log("Checking Row " + i);
                              console.log(value);
                              console.log(value2).value;
                              i++;
                              });
                       
        })

Help greatly appreciated as i am way more an ObjectiveC person than i am a Javascript/JQuery person!

Thanks

Hi Gareth, 


See the blog below, it has Sample code for JQuery Sortable and VisualForce along with more information, 

<apex:page controller="ProductSort" showheader="true">
