Simple Pagination of a Sublist in a Suitelet

The following code creates a Suitelet that displays a Sublist from a saved search with a simple pagination using a dropdown.
The Suitelet interacts references a Client script for the fieldChange operations done when the value of the dropdown is changed.

Suitelet Script:

/**
 * @param {nlobjRequest}  request Request object
 * @param {nlobjResponse} response Response object
 * @returns {Void} Any output is written via response object
 */
function suitelet(request, response) {

 var form = nlapiCreateForm('Web Store Items');

 // a simple drop down to select which records from the result to display
 var fld = form.addField('custpage_rows', 'select', 'View Row Numbers');
 fld.addSelectOption('3', '1 to 3');
 fld.addSelectOption('6', '4 to 6');
 fld.addSelectOption('9', '7 to 9');

 // sets a client script
 form.setScript('customscript128');
 var rowsPerPage = 3;
 var rowCount = request.getParameter('custpage_rows');
 if (null == rowCount || rowCount == '') {
  rowCount = rowsPerPage;
 }

 var rowCountURL = request.getParameter('param_rowCount');
 if (null != rowCountURL && rowCountURL != '') {
  rowCount = rowCountURL;
  fld.setDefaultValue(rowCount);
 }

 form.addSubTab('tab1', 'Web Store Items');
 var sublist = form.addSubList("custpage_sublist", "staticlist", "Sublist",
   "tab1");
 sublist.addField('itemid', 'text', 'Name');
 sublist.addField('displayname', 'text', 'Display Name');
 sublist.addField('salesdescription', 'text', 'Description');
 sublist.addField('type', 'text', 'Type');
 sublist.addField('baseprice', 'currency', 'Base Price');
 
 // the records to be displayed are from a saved search
 var s = nlapiLoadSearch('item', 'customsearch22');
 var resultSet = s.runSearch();

 // only display rows from the search result that matches the value in the drop down
 var results = resultSet.getResults(rowCount - rowsPerPage, rowCount);
 for ( var i = 0; results != null && i < results.length; i++) {
  var row = i + 1;
  searchresult = results[i];
  sublist.setLineItemValue('itemid', row, searchresult.getValue('itemid'));
  sublist.setLineItemValue('displayname', row, searchresult.getValue('displayname'));
  sublist.setLineItemValue('salesdescription', row, searchresult.getText('salesdescription'));
  sublist.setLineItemValue('type', row, searchresult.getValue('type'));
  sublist.setLineItemValue('baseprice', row, searchresult.getValue('baseprice'));
 }

 response.writePage(form);

}


Client Script:

/**
 * The recordType (internal id) corresponds to the "Applied To" record in your script deployment.
 * @appliedtorecord recordType
 *
 * @param {String} type Sublist internal id
 * @param {String} name Field internal id
 * @param {Number} linenum Optional line item number, starts from 1
 * @returns {Void}
 */
function clientFieldChanged(type, name, linenum) {

 if (name == 'custpage_rows') {
  var rowCount = nlapiGetFieldValue('custpage_rows');
  var url = window.location.search;
  if (url.indexOf('&param_rowCount') > 0) {
   // Remove the previous value of the parameter: param_rowCount
   url = url.substring(0, url.indexOf('&param_rowCount'));
  }
  // The code below refreshes the page and passes the value of the dropdown
  // in the URL as a parameter
  window.location.search = url + '&param_rowCount=' + rowCount;
 }

}
