jun*_*zal 2 javascript jquery json
我正在尝试在javascript中创建命名对象,如下所示:-
{
id: "marker_0",
tooltip: country,
src: "//localhost/mapsvg/markers/pin1_red.png",
width: 15,
height: 24,
geoCoords: [latitude, longitude]
},
{
id: "marker_1",
tooltip: country,
src: "//localhost/mapsvg/markers/pin1_red.png",
width: 15,
height: 24,
geoCoords: [latitude, longitude]
}

等等。我从数据库中获取国家,纬度,经度值。下面是我的代码:-
var objFormat;
var i =0;
var mapFormat = [];
for (var country in countries_coord) {
values = countries_coord[country];
objFormat = '{"id:" "marker_""' + i + '","tooltip:" "' + country + '","src:" "//localhost/mapsvg/markers/pin1_red.png","width:" "'+ 15 + '","height:" "'+ 24 + '","geoCoords:" [ "'+ values.latitude + '", "'+values.longitude + '" ]}';
obj = $.parseJSON(objFormat);
mapFormat.push(objFormat);
i++;
}

但我收到错误消息“ Uncaught SyntaxError:JSON中位置7处的意外字符串”。我认为我没有以正确的方式创建对象。请帮忙。提前致谢。
编辑
这是我在countries_coord数组中具有完整JSON的内容:-
Afghanistan
:
Object
latitude
:
"33.93911"
longitude
:
"67.709953"
Australia
:
Object
latitude
:
"-25.274398"
longitude
:
"133.775136"

依此类推,我还有另一个格式相同的值。
我错过了一个问题,那就是解决方案
更改
objFormat = '{"id:" "marker_""' + i + '","tooltip:" "' + country + '","src:" "//localhost/mapsvg/markers/pin1_red.png","width:" "'+ 15 + '","height:" "'+ 24 + '","geoCoords:" [ "'+ values.latitude + '", "'+values.longitude + '" ]}';

至
objFormat = '{"id": "marker_' + i + '",'+
'"tooltip": ' + country + '",'+
//etc
'"geoCoords": [ '+ values.latitude + ', '+values.longitude+' ]}';

请注意,我如何使用代码缩进来使我在遇到错误时更容易看到。您在冒号后面加上了报价。
JSON对象必须是单个对象或对象数组,因此您需要
[
{
id: "marker_0",
tooltip: country,
src: "//localhost/mapsvg/markers/pin1_red.png",
width: 15,
height: 24,
geoCoords: [latitude, longitude]
},
{
id: "marker_1",
tooltip: country,
src: "//localhost/mapsvg/markers/pin1_red.png",
width: 15,
height: 24,
geoCoords: [latitude, longitude]
}
]

要么
{
location_list: [
{
id: "marker_0",
tooltip: country,
src: "//localhost/mapsvg/markers/pin1_red.png",
width: 15,
height: 24,
geoCoords: [latitude, longitude]
},
{
id: "marker_1",
tooltip: country,
src: "//localhost/mapsvg/markers/pin1_red.png",
width: 15,
height: 24,
geoCoords: [latitude, longitude]
}
]
}
