SPServices Code to update list items

Hi Folks,

I did an enhancement in my project to update multiple list items using jQuery SPServices. I tried very hard to use EcmaScript to update multiple list items but unfortunately it didn't work out. Finally, I had to depend on my old buddy i.e. SpServices to implement it. Basically, I've a parent list with a Primary Key which acts as a Foreign Key in Child list. From Parent list's Editform.aspx, I've to update the items based on 1 Yes/No field value in parent list which will update the Yes/No field in child list items. The Key is helpful in doing that but we've to use ID field to update items.
Here's the code below.

<script type="../SiteAssets/jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="../SiteAssets/sputility.min.js"></script>
<script type="text/javascript" src="../SiteAssets/url.js"></script>
<script type="text/javascript" src="../SiteAssets/jquery.SPServices-2013.01.min.js"></script>
<script type="text/javascript" src="../SiteAssets/jquery.SPServices-2013.01.js"></script>

<script type="text/javascript">

var cuidSox;

var context;

var website;

var list;

var items;

var itemCount;

/*$(document).ready(function() {

});*/

function PreSaveAction(){

SP.SOD.executeFunc('sp.js', 'SP.ClientContext', SharePointReady);

// Update SOx list

return true;

}

function SharePointReady(){

cuidSox = $("input[title='Control UID']").val(); //Control UID from Sox control Master List which acts as Primary Key in Parent List and Foreign key in child list

if( $("input[id='ctl00_ctl40_g_48a5562b_7b23_4406_b69b_561200fe8c87_ff151_ctl00_ctl00_BooleanField']").is(':checked')) { 

    var queryXml = "<View><Query><Where><Eq><FieldRef Name = 'ControlUID'/><Value Type='Text'>" + cuidSox + "</Value></Eq></Where></Query></View>";

var query = new SP.CamlQuery();

query.set_viewXml(queryXml);

    context = new SP.ClientContext.get_current();

website = context.get_web();

list = website.get_lists().getByTitle('Monitoring List');

items = list.getItems(query);

context.load(items);

context.executeQueryAsync(onRequestSucceeded, onRequestFailed);

} 

else{

//no action needed

}

}

function onRequestSucceeded() {

itemCount = items.get_count();

//alert(itemCount);  

var enumerator = items.getEnumerator();

while (enumerator.moveNext()) {           

var currentItem = enumerator.get_current();

var itemId = currentItem.get_item('ID');

//alert(itemId);

$().SPServices({

  operation: "UpdateListItems",

  async: false,

  batchCmd: "Update",  

  listName: "Monitoring List", 

  ID: itemId, //Without ID field it won't update the values based on parameter value. That's why with Control UID wasn't working before

  valuepairs: [["Retired",1]],

  debug: false,

  completefunc: function(xData, Status) {}

});

}

confirm(itemCount+" items got retired in Monitoring list");

}

function onRequestFailed(sender, args) {

        alert('Error: ' + args.get_message());

}

</script>
