使用JS将新字段添加到我的html页面并检查.XML.PHP文件中的自动完成

Question

want to add one more auto-complete input field i have no ides how to do it. adding new field to to my html page using JS and checking for auto complete in .XML.PHP file

this is my .js file

        (function(){
      var WINDOW=window,
      DOCUMENT=document,
      SCAN=gui.app.scan,
      SYS=gui.system,
      U=gui.util,
      D=gui.dom,
      E=gui.event,
      W=gui.widget,

      form,
      formname='gblForm-Unit',
      autos={},
      reqd={
        fields:['unitId'],
        types:{
          'unitId':'alphanum'
        }
      };

      /**
       * Set a field as required if it exists
       * @private
       * @param {String} id ID of the field
       * @returns {Void}
       */
      function setRequired(id){
        if (D.get(id)){
          reqd.fields.push(id);
        }
      }

Handles the onLoad event for the window

      function onload(){
        if (SCAN.ENABLE_JAVASCRIPT){
          if (D.get('#'+ formname)){
            setRequired('unitId');

            form=new U.FormSubmit(formname, reqd, ws.error.getFormError);
            form.registerScanningField('unitId');
            form.registerButton([
              { id:'gblBtn-Submit', type:'submit' }
            ]);
          }
          }
         }

          E.add(WINDOW, 'load', onload);
         }());

this is my .xml.php page

      <?php
       try {
        $unitId=ws::scrub(@$_GET['unitId'], 'alphanum');

        $xml = new wsResultDocument();
        $data = $xml->getNodeSet('data');

        if ($unitId){
            $unit = wsModel::execSP('GetUnit', array('data' => $unitId));

            if (!sizeof($unit)){
                throw new UserException('UNIT_VALUE_INVALID', $unitId);
            }

            $groups = array(
                array(
                    'column'    => 'UNMT_Serial',
                    'table' => 'UNMT',
                    'nodeName'  => 'unit',
                ),
                array(
                    'column'    => 'UTDT_Label',
                    'table' => 'UTDT',
                    'groupName' => 'values',
                    'nodeName'  => 'value',
                ),
            );

            $data->addNodeSet(wsResult::groupedNodeSet($unit, $groups, null, false));
        }
      }
      catch(Exception $e){
        wsError::logException($e);
        $xml = wsError::exceptionToResult($e);
    }

    return $xml;
    ?>
