在Javascript操作JSON对象，增加删除修改全有的，详情见代码
var jsonObj2New = {};
$("#btn").click(function () {
//invoke the update
updateData("jordan");
var persons = jsonObj2.teacher;
for (var i = 0; i < persons.length; i++) {
var cur_person = persons[i];
alert(cur_person.sex);
}
$("#btn").click(function () {
//invoke the update
updateData("jordan");
var persons = jsonObj2.teacher;
for (var i = 0; i < persons.length; i++) {
var cur_person = persons[i];
alert(cur_person.sex);
}
//invoke the delete
deleteData("jordan");
var persons = jsonObj2.teacher;
for (var i = 0; i < persons.length; i++) {
var cur_person = persons[i];
alert(cur_person.sex);
}
//push
var temp = { name: "kenny",age: "25" };
jsonObj2.teacher.push(temp);
var persons = jsonObj2.teacher;
for (var i = 0; i < persons.length; i++) {
var cur_person = persons[i];
alert(cur_person.name);
}});
function updateData(name) {
var persons = jsonObj2.teacher;
//alert(name);
for (var i = 0; i < persons.length; i++) {
var cur_person = persons[i];
if (cur_person.name == name) {
persons[i].sex = "f";
}
}
}
function deleteData(name) {
var persons = jsonObj2.teacher;
//alert(name);
for (var i = 0; i < persons.length; i++) {
var cur_person = persons[i];
if (cur_person.name == name) {
jsonObj2.teacher.splice(i,1);
}
}
}
