json转[,]这种类型怎么转？

[-一个大坑]

api返回的的json

[{
		"latitude": 22.56671,
		"longitude": 113.455162
	},
	{
		"latitude": 22.5667725,
		"longitude": 113.45546
	},
	{
		"latitude": 22.5661736,
		"longitude": 113.455894
	},
	{
		"latitude": 22.5669842,
		"longitude": 113.455086
	},
	{
		"latitude": 22.5664921,
		"longitude": 113.455437
	}
]

转成lineArr = [[113.455163, 22.56671], [113.455462, 22.566773], [113.455897, 22.566173], [113.455087, 22.566985], [113.455433, 22.566493]];

var lineArr = [{
        "latitude": 22.56671,
        "longitude": 113.455162
    },
    {
        "latitude": 22.5667725,
        "longitude": 113.45546
    },
    {
        "latitude": 22.5661736,
        "longitude": 113.455894
    },
    {
        "latitude": 22.5669842,
        "longitude": 113.455086
    },
    {
        "latitude": 22.5664921,
        "longitude": 113.455437
    }
].map(function(obj){
 return [obj.longitude,obj.latitude]
})

引用 1 楼 xzy21com 的回复:

var lineArr = [{
        "latitude": 22.56671,
        "longitude": 113.455162
    },
    {
        "latitude": 22.5667725,
        "longitude": 113.45546
    },
    {
        "latitude": 22.5661736,
        "longitude": 113.455894
    },
    {
        "latitude": 22.5669842,
        "longitude": 113.455086
    },
    {
        "latitude": 22.5664921,
        "longitude": 113.455437
    }
].map(function(obj){
 return [obj.longitude,obj.latitude]
})

举例可以，但是我遇到了点问题
网页显示
[{"longitude":113.455162,"latitude":22.56671},{"longitude":113.45546,"latitude":22.5667725},{"longitude":113.455894,"latitude":22.5661736},{"longitude":113.455086,"latitude":22.5669842},{"longitude":113.455437,"latitude":22.5664921},{"longitude":113.455139,"latitude":22.5663662},{"longitude":113.455284,"latitude":22.5668678}]
我用取了后var trackArr = $('#Label1').text();就是这样了
"[{\"longitude\":113.455162,\"latitude\":22.56671},{\"longitude\":113.45546,\"latitude\":22.5667725},{\"longitude\":113.455894,\"latitude\":22.5661736},{\"longitude\":113.455086,\"latitude\":22.5669842},{\"longitude\":113.455437,\"latitude\":22.5664921},{\"longitude\":113.455139,\"latitude\":22.5663662},{\"longitude\":113.455284,\"latitude\":22.5668678}]"

好了，要把json字符串转成json格式
var strObj = JSON.parse(trackArr);
