java中的JSONP使用实例详解

private void GetTop10() throws IOException {
  String jsonCallback = _request.getParameter("jsonCallback");
  String id = _request.getParameter("id");
  String return_JSONP = top10Setup.ReadTop10(id );
  return_JSONP = jsonCallback + "(" + return_JSONP  + ");";
  System.out.println( return_JSONP );
  _response.getWriter().println( return_JSONP  );
}

function appendListOne() {
  $.jsonp({
    'contentType': "application/json; charset=utf-8",
    'url': AjaxGetUrl,
    'data': {
      dz_type: 'GetTop10',
      id: 17
    },
    'dataType':"jsonp",
    'callbackParameter':"jsonCallback",
    'async':false,
    'type': 'post',
    'success': function (data) {
      console.warn( data );
      $("#list1>tbody").empty();
      var str="";
      for(var key=0;key<data.dblist.length;key++){
        var dd=data.dblist[key];
        if(key <5){
          str+='<tr><td><b class="ranking">' +(parseInt(key)+1)+
            '</b><span class="name">'+dd.data_name+'</span></td>' +
            '<td> <span class="detail">'+dd.data_value+'.'+dd.data_value2+'.'+dd.data_value3+'.'+dd.data_value4
