function sum(){
var trArrays =document.getElementsById("id").getElementsByTagName("TR");
for(var index=0;index<trArrays.length;index++){
var tdArrays = trArrays[index].children;
sum+=parseInt(tdArrays[5].innerText);
}
document.cj.p.value=sum;

下面是需要取值的jsp页面代码

db.getConnection();//调用DBConnection数据库连接方法
String sql1="select question.questionNo,questionType,stuAnswer.paperNo,questionAnswer,submitAnswer from questionType,question,stuAnswer,paperRules where stuNo='"+stuNo+"'and question.questionNo=stuAnswer.questionNo and stuAnswer.paperNo=paperRules.paperNo and psubject='"+subject+"' and question.questionTypeNo=questionType.questionTypeNo and question.questionTypeNo!='01'and question.questionTypeNo!='05'";

我想将下面表格文本框输入的数字提交到js函数，并进行自动求和从而显示在另一个文本框p的值
