如何從JQuery Auto獲取正確的數據完成多個數據發送？

Question

我正在嘗試在我的web應用程序中實現自動完成功能。數據從我的服務器加載到自動完成功能。我使用Jquery AutoComplete爲了這個目的 - http://jqueryui.com/autocomplete/#remote-jsonp

下面是我的jQuery代碼

$(document).ready(function() { 
    $(function() { 
     $("#addDrugTxt").autocomplete({ 
      source: function(request, response) { 
       $.ajax({ 
        url: "Autocomplete", 
        type: "POST", 
        data: { term: request.term }, 

        dataType: "json", 

        success: function(data) { 
         response(data); 
        } 
       });    
      }, 
      minLength: 2, 

      select: function(event, ui) { 
     log("Selected: " + ui.item.label); 
     } 
     }); 
     $("#addDrugTxt").autocomplete("option", "appendTo", ".form-horizontal"); 
    }); 
}); 

function log(message) { 
     document.getElementById("brandTxt").value = message; 

     alert("damn"); 
    } 

下面是我的Java代碼，將數據提供給jQuery代碼。

public class Autocomplete extends HttpServlet { 

    private final List<String> drugList = new ArrayList<String>(); 
    int idUser=0; 

    @Override 
    public void init() 
    { 


    } 

    /** 
    * Processes requests for both HTTP <code>GET</code> and <code>POST</code> 
    * methods. 
    * 
    * @param request servlet request 
    * @param response servlet response 
    * @throws ServletException if a servlet-specific error occurs 
    * @throws IOException if an I/O error occurs 
    */ 
    protected void processRequest(HttpServletRequest request, HttpServletResponse response) 
      throws ServletException, IOException { 
     response.setContentType("text/html;charset=UTF-8"); 
     PrintWriter out = response.getWriter(); 

     idUser=Integer.parseInt(request.getSession(false).getAttribute("UserID").toString()); 

     try { 

      drugList.clear(); 
      DrugNamesTable table = new DrugNamesTable(); 
      List<DrugNamesBean> drugNames = table.getDrugNames(idUser); 
      System.out.println("Drug names taken"); 



     // Map real data into JSON 

     response.setContentType("application/json"); 

     final String param = request.getParameter("term"); 
     final List<AutoCompleteData> result = new ArrayList<AutoCompleteData>(); 
     for (final DrugNamesBean data: drugNames) { 
      if (data.getDrugName().toLowerCase().startsWith(param.toLowerCase())) { 
       result.add(new AutoCompleteData(String.valueOf(data.getIdDrugName()), data.getDrugName())); 
      } 


     } 
     response.getWriter().write(new Gson().toJson(result)); 
     } finally { 
      out.close(); 
     } 
    } 
} 

在上面的Java代碼中，我使用了一個名爲AutoCompleteData的bean。它的代碼如下。

public class AutoCompleteData { 

    private final String label; 
    private final String value; 

    public AutoCompleteData(String _label, String _value) { 
     super(); 
     this.label = _label; 
     this.value = _value; 
    } 

    public final String getLabel() { 
     return this.label; 
    } 

    public final String getValue() { 
     return this.value; 
    } 

} 

但是我要的是顯示AutoCompleteData._value時自動完成建議都上來了。不幸的是，我得到的都是AutoCompleteData._label。

當然AutoCompleteData._label對我很重要，因爲我還需要動態更改addDrugTxt的id。

我該如何解決這個問題？

Answer 1

答案很簡單。我所要做的只是在下面。

AutoCompleteData { 

    private final String label; 
    private final String value; 
    private String id; 

    public AutoCompleteData(String _label, String _value, String _id) { 
     super(); 
     this.label = _label; 
     this.value = _value; 
     this.id = _id; 
    } 

    public final String getLabel() { 
     return this.label; 
    } 

    public final String getValue() { 
     return this.value; 
    } 

    /** 
    * @return the id 
    */ 
    public String getId() { 
     return id; 
    } 


} 

然後在AutoComplete.java我送兩個2個參數drug name和id在最後一個參數。

result.add(new AutoCompleteData(data.getDrugName(),data.getDrugName(),String.valueOf(data.getIdDrugName()))); 

在JQuery很容易採取其他值這樣的..

select: function(event, ui) { 
     log(ui.item.id); 
     }
