Ajax遍历jSon进行数据的修改和删除

$.ajax({
url: "/business/findpersons.json",
dataType: "json",
type:"GET",
success: function(doc) {
var objs=eval(doc);
for (var i = 0; i < objs.length; i++){
var personid=objs[i].personId;
var name=objs[i].personName;
var email=objs[i].personEmail;
var sector=objs[i].personSector;
var position=objs[i].personPosition;
var password=objs[i].personPassword;
$("#personList thead").append(
"<tr>"+ 
"<th>"+name+"</th>"+ 
"<th>"+password+"</th>"+
"<th>"+email+"</th>"+
"<th>"+position+"</th>"+
"<th><input type='button' value='删除' name="+i+" class='deletePersonBut'></th>"+
"<th><input type='button' value='修改' name="+i+" class='updataPersonBut'></th>"+
"</tr>" 
);
var getA = "#personList .deletePersonBut[name="+ i + "]";//就这里获取的原因，那个i=objs.length的原因，感觉应该就是闭包的问题。 
$(getA).click(function(){ 
var thid=$(this).parent();
var pid=thid.children(".deletePersonBut").attr('name');
alert(objs[pid].personId); 
});
var getA = "#personList .updataPersonBut[name="+ i + "]";//就这里获取的原因，那个i=objs.length的原因，感觉应该就是闭包的问题。 
$(getA).click(function(){ 
var thid=$(this).parent();
var pid=thid.children(".updataPersonBut").attr('name');
alert(objs[pid].personId);
