哈哈哈哈！这么快！应该把我的源代码贴上来。

var answer1 = answerOld.slice(0,6).join("||");
var answer2 = answerOld.slice(6,12).join("||");
var answer3 = answerOld.slice(12,18).join("||");
var answer4 = answerOld.slice(18,24).join("||");
var answer5 = answerOld.slice(24).join("||");
function loadDbData1(){
    return answer1;
}
function loadDbData2(){
    return answer2;
}
function loadDbData3(){
    return answer3;
}
function loadDbData4(){
    return answer4;
}
function loadDbData5(){
    return answer5;
}
var answer = {};
function query(){
    answer[0] = answer1+"||"+answer2+"||"+answer3+"||"+answer4+"||"+answer5;
    window.parent.doHomework(uid,cname,answer);
}
function qna1(){
    answer1 = arguments[0];
    query();
}
function qna2(){
    answer2 = arguments[0];
    query();
}
function qna3(){
    answer3 = arguments[0];
    query();
}
function qna4(){
    answer4 = arguments[0];
    query();
}
function qna5(){
    answer5 = arguments[0];
    query();
}

;(function (window, undefined) {
window.parent.getAnswer(uid,cname).split('||')
  .reduce(function (result, item, index) {
    index % 6 === 0 ? result.push([item]) : result[result.length - 1].push(item);
    return result;
  }, [])
  .forEach(function (answer, index, self) {
      window['loadDbData' + (index + 1)] = function () {
      //top.console.log(answer.join("||"));
      return answer.join("||");
    };

    window['qna' + (index + 1)] = function (replacement) {
      this.parent.doHomework(uid, cname, {
        '0': (function ( me ) {
                me.splice(index, 1, replacement);
                //top.console.log(me.join('||'));
                return me.join('||');
             })( self.slice(0) )
      });
    };
  });
}).call(this, this);

把上面的代码换成了下面的，顿时觉得高端大气上档次多了！
