jQuery.Autocomplete与struts2的整合

ssh中jquery autocomplete使用示例

jQuery.Autocomplete与struts2的整合

 

以下是我的实践,不过不知道为什么autocomplete功能不能从返回的json对象中选择包含输入字段的一项,例如source:person!ajaxSelectPerson ,这个时候person! ajaxSelectPerson返回的json,当输入wang时,当source: ["张三","李斯","王五","赵六","黑龙","白海","湘伦"]时

 

package com.maple.action;
 
 import java.io.PrintWriter;
 import java.util.ArrayList;
 import java.util.Date;
 import java.util.List;
 
 import net.sf.json.JSONArray;
 
 import org.apache.struts2.ServletActionContext;
 import org.apache.struts2.convention.annotation.ResultPath;
 
 import com.opensymphony.xwork2.ActionSupport;
 
 @ResultPath("/")
 //@Results({@Result(name="")})
 public class PersonAction extends ActionSupport{
     public String result;
     public String getResult() {
         return result;
     }
     public void setResult(String result) {
         this.result = result;
     }
     public String autocom()
     {
         result="[\"zhangsan\",\"lisi\",\"wangwu\",\"zhangsan\",\"sun\",\"zhouw\",\"hello\",\"world\",\"nihsi\"]";
         return "autocom";
     }
     public String ajaxSelectPerson(){ 
         try { 
         String search = ServletActionContext.getRequest().getParameter("term"); 
         System.out.println(search);
 //        if(search==null||search.length()==0) return null; 
         List<String> names = new ArrayList<String>(); 
                            names.add("zhangsan"); 
                            names.add("lisi");

         ServletActionContext.getResponse().setCharacterEncoding("UTF-8"); 
         JSONArray json = JSONArray.fromObject(names); 
         PrintWriter out = ServletActionContext.getResponse().getWriter(); 
         out.print(json.toString()); 
         System.out.println(new Date()+"  "+json);
                 out.flush(); 
                 out.close(); 
                 return null;
