Question

嗨，我是json的新手。我正在尝试将json文件解析成一个网页，就像在这个帖子中解释的那样.........

但是我的json文件是一个很大的联系人列表，它们不在上面例子中的'people'之类的数组中。相反，我的json文件的前6行如下所示。

{ "first_name": "Tom", "last_name": "Moore", "phone": "123456", "email": "tom@abc.ie" }
{ "first_name": "Fred", "last_name": "Power", "phone": "197412", "email": "fred@abc.ie" }
{ "first_name": "Ann", "last_name": "Doyle", "phone": "836547", "email": "ann@abc.ie" }
{ "first_name": "Phil", "last_name": "Jones", "phone": "927481", "email": "phil@abc.ie" }
{ "first_name": "Jane", "last_name": "Ross", "phone": "993377", "email": "jane@abc.ie" }
{ "first_name": "Tom", "last_name": "Moore", "phone": "123456", "email": "tom@abc.ie" }

如何在上面的线程中循环显示它们？非常感谢提前。

Answer 1

你的json无效。它需要外部的方括号和项目之间的逗号。它应该是：

[
    { "first_name": "Tom", "last_name": "Moore", "phone": "123456", "email": "tom@abc.ie" },
    { "first_name": "Fred", "last_name": "Power", "phone": "197412", "email": "fred@abc.ie" },
    { "first_name": "Ann", "last_name": "Doyle", "phone": "836547", "email": "ann@abc.ie" },
    { "first_name": "Phil", "last_name": "Jones", "phone": "927481", "email": "phil@abc.ie" },
    { "first_name": "Jane", "last_name": "Ross", "phone": "993377", "email": "jane@abc.ie" },
    { "first_name": "Tom", "last_name": "Moore", "phone": "123456", "email": "tom@abc.ie" }
]

$.getJSON为你处理json解析 - 只需执行：

$.getJSON('/url/of/the/json/file', function(people) {
    alert(people[0].first_name)
});

Answer 2

这不是json格式，所以你将无法使用json的函数来处理它。我建议在服务器端使用lib / function来创建正确的json输出，然后在客户端使用它也会容易得多。

Answer 3

var t = eval('[{ "first_name": "Tom", "last_name": "Moore", "phone": "123456", "email": "tom@abc.ie" },{ "first_name": "Fred", "last_name": "Power", "phone": "197412", "email": "fred@abc.ie" },{ "first_name": "Ann", "last_name": "Doyle", "phone": "836547", "email": "ann@abc.ie" },{ "first_name": "Phil", "last_name": "Jones", "phone": "927481", "email": "phil@abc.ie" },{ "first_name": "Jane", "last_name": "Ross", "phone": "993377", "email": "jane@abc.ie" },{ "first_name": "Tom", "last_name": "Moore", "phone": "123456", "email": "tom@abc.ie" }]');

for (i in t) {
var data = t[i];
  for (k in data) {
    alert(k+" >> "+data[k])
  }
}

你可以得到＆＃34; k＆＃34;作为关键和＆＃34;数据[k]＆＃34;作为价值。
