$.getJSON的用法

struts2中的action：

public void getSynonymy()
{
    DataJsonBean dataBean = new DataJsonBean();
    dataBean.setInterestNameString("['低','中','高']");
    dataBean.setInterestValueString("['3','1','8']");

    String resultStr = this.getChinese();

    resultStr = new String(resultStr.getBytes("iso-8859-1"),"UTF-8");

    dataBean.setChinese(resultStr+"的同义近义词");
    JSONObject data = new JSONObject(dataBean);
   
    PrintWriter out = null;
    try
    {
        HttpServletResponse response = ServletActionContext.getResponse();
        response.setContentType("application/json;charset=UTF-8");
        out = response.getWriter();
        out.print(data.toString());
    }
    catch (IOException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    finally
    {
        out.flush();
        out.close();
    }
}

展示的jsp:

//引用struts2的标签

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

//获取工程的路径：

<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<script type="text/javascript">

function search(method)
{
 $.getJSON("<%=basePath%>semanticRelationshipAction!"+method+".action",{chinese:$("#chinese").val()},
  function(data)
  {

   $("#result").css({display:"block"});
   $("#labelChinese").html(data.chinese);
   alert(data.interestNameString);
   aturCommonLoad(data.interestNameString,data.interestValueString);
  }
 );
}
</script>

<input class="ttinput" type="text" name="chinese" id="chinese"/>

<input class="ttbutton" type="button" value="同义近义" onclick="search('getSynonymy')"/>

<div id="result" class="result" style="display: none">
    <div class="texttitile" id="labelChinese"></div>
    <div id="interest"></div>
   </div>
