使用prototype.js经验积累

1、Ajax返回xml格式的对象

1）前台js

function viewIndexGrade(id){

       var offsetObj = event.srcElement;

       var url = "<ww:url value='/xxxAction!getIndexGrades.action'/>?obj.id=" + id;

       var http = new Ajax.Request(url,

              {method: 'get',

              asynchronous: false,

              onComplete:function(oriReq){

                     var divObj = document.getElementById("indexGradDiv");

                     var sb = "<table class='table-border' align='center' cellspacing='1' cellpadding='1' width='100%'>";

                     var responseDoc = oriReq.responseXML;

                     var records = responseDoc.documentElement.childNodes;

                     if(records.length > 0){

                            for(var i = 0; i < records.length; i++){

                                   var indexCode = records[i].selectSingleNode("indexCode").text;

                                   var grade = records[i].selectSingleNode("grade").text;

                                   sb += "<tr>";

                                   sb += "<td class='table-title' style='height:25px' align='left' width='40%'>" + indexCode + "</td>";

                                   sb += "<td class='table-content' style='height:25px' align='center'>" + grade + "</td>";

                                   sb += "</tr>";

                            }

                            sb +
