用纯javascript写的异步调用js文件xmlcommon.js三

后台代码：

1.AjaxUtil.java

package com.tpaic.ruleengine.util;

import java.util.List;

import com.tpaic.ruleengine.domain.DecisionRule;
import com.tpaic.tpfa.app.util.CommonFunctions;
import com.tpaic.tpfa.app.web.util.Builder;

public class AjaxUtil {
 
 public static String buildOptions(List list, String itemName) {
  if(CommonFunctions.isEmpty(list)){
   return "";
  }
  StringBuffer xmldata = new StringBuffer();
  Builder.appendSelectBegin(xmldata, itemName);
  xmldata.append("<options>");
  Builder.appendOptionValue(xmldata, "请选择", "");
  if (list != null && list.size() > 0) {
   for (int i = 0; i < list.size(); i++) {
    DecisionRule obj = (DecisionRule) list.get(i);
    Builder.appendOptionValue(xmldata,obj.getRuleName(), obj.getRuleId());
   }
  }
  xmldata.append("</options>");
  Builder.appendSelectEnd(xmldata, itemName);
  return xmldata.toString();
 }
