循环接收到的json字符串以通过jquery获取值 [英] loop a recieved json string to get values by jquery

问题描述

我正在尝试解析从$.post()返回的数据.

I'm trying to parse data returned from $.post().

[{"id":"1","text":"USD"},
 {"id":"2","text":"CNY"},
 {"id":"3","text":"PHP"},
 {"id":"4","text":"AUD"},
 {"id":"5","text":"SGD"},
 {"id":"6","text":"JPY"}]

使用这种方法 jQuery，遍历json数组

我做了这样的事情:

$.post(
    base_url+'cgame/currency',
    { gameID: gameID },
    function(data) {
        $(this).html();
        $.each(data,function(idx, obj) {
            $(obj).each(function(key, value) {
                console.log(key + ": " + value);
            });
        });
    }
);

但是它给了我错误:

未捕获的TypeError:无法使用'in'运算符在[{"id":"2","text":"CNY"},{"id":"3","text":"PHP"},{"id":"4","text":"AUD"},{"id":"5","text":"SGD"},{"id":"6","text":"JPY"}]中搜索'120'

Uncaught TypeError: Cannot use 'in' operator to search for '120' in [{"id":"2","text":"CNY"},{"id":"3","text":"PHP"},{"id":"4","text":"AUD"},{"id":"5","text":"SGD"},{"id":"6","text":"JPY"}]

我也尝试过:

$.post(
    base_url+'cgame/currency',
    { gameID: gameID },
    function(data) {
        $(this).html();
        $(data).each(function(idx, obj) {
            $(obj).each(function(key, value) {
                console.log(key + ": " + value);
            });
        });
    }
);

但这也给了我错误:

未捕获的错误:语法错误，无法识别的表达式:[{"id":"1","text":"USD"},{"id":"6","text":"JPY"}]

我应该怎么做?

推荐答案

 function(data) {
    var value = JSON.parse(data);
    $.each(value ,function(idx, obj) {
       console.log("id : "+obj.id+" "+text:"+obj.text);
    });
 }
