在Javascript操作JSON對象/增加 刪除 修改的簡單實(shí)現(xiàn)

    在Javascript操作JSON對象，增加刪除修改全有的，詳情見代碼
    代碼如下:
    <script type="text/javascript">
      var jsonObj2 = { teacher: [
        { name: "jordan", sex: "m", age: "40" },
        { name: "bryant", sex: "m", age: "28" },
        { name: "McGrady", sex: "m", age: "27" }
      ]};
      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);
        }
        //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", sex: "m", 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);
          }
        }
      }
      </script>
