The example of this article describes how jquery uses the each method to traverse json format data. Share it with everyone for your reference. The specific implementation method is as follows:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<script src="jquery-1.6.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
  //$.each(array,fn)对数组arry每个元素调用fn函数进行处理，没有返回值
  var arr = { "tom": "汤姆", "jerry": "杰瑞", "lily": "莉莉" };
  //json格式的对象(dict)
  $.each(arr, function (key, value) { alert(key + "=" + value); });
  //如果是普通风格的数组，则key的值是序号。
</script>
</head>
<body>
</body>
</html>
