js获取json数据

{"code":0,"data":{"ip":"210.75.225.254","country":"\u4e2d\u56fd","area":"\u534e\u5317",
"region":"\u5317\u4eac\u5e02","city":"\u5317\u4eac\u5e02","county":"","isp":"\u7535\u4fe1",
"country_id":"86","area_id":"100000","region_id":"110000","city_id":"110000",
"county_id":"-1","isp_id":"100017"}}

请问怎么用JS取得city county的值

Answer 1

这些值是你在后台打出来的吧
传到前台来是个一个字符串类型，需要经过转换才可以像对象那样点出来里面的值
架设你JS里面接收这个字符串的变量叫
strJson

var json = eval('(' + strJson + ')');
alert(json.city);
alert(json.country);

Answer 2

//javascript
var data = '{"code":0,"data":{"ip":"210.75.225.254","country":"\u4e2d\u56fd","area":"\u534e\u5317",
"region":"\u5317\u4eac\u5e02","city":"\u5317\u4eac\u5e02","county":"","isp":"\u7535\u4fe1",
"country_id":"86","area_id":"100000","region_id":"110000","city_id":"110000",
"county_id":"-1","isp_id":"100017"}}';

var result=eval('('+data+')');
var country= result.data.country;

Answer 3

var Data = eval('(' + json + ')');var json1 = Data.channel.item; // item是数组var r = "";for (var i = 0; i < json1.length; i++) { var obj = json1[i]; r += obj.title + "" + obj.description; var cateforys = obj.catefory; // catefory是数组 for (var j = 0; j < cateforys.length; j++) { // 中括号方式获取js变量中不允许出现的 var catefory = cateforys[j]; r += catefory["-domain"] + catefory["#text"]; }}alert(r);

Answer 4
