在做一个echart的地图拓展，要添加动态的标线。现在碰到不知道怎么去格式化echart想要的数据格式。我后台传过来的格式是（json）：[
{
"wFrom": {
"fLatitude": "114.057868",
"fLongitude": "22.543099",
"fName": "深圳市"
},
"wTo": {
"tLatitude": "37.6173",
"tLongitude": "55.755826",
"tName": "Moscow"
},
"wValue": "31",
"wkey": "深圳市",
"wproperties": "bag"
},
{
"wFrom": {
"fLatitude": "116.681972",
"fLongitude": "23.354091",
"fName": "汕头市"
},
"wTo": {
"tLatitude": "37.6173",
"tLongitude": "55.755826",
"tName": "Moscow"
},
"wValue": "24",
"wkey": "汕头市",
"wproperties": "Baby Toys"
}, ]
想要的格式是：[
[
{name: '北京', value: 100},
{name:'上海'}
],
[
{name: '北京', value: 100},
{name:'广州'}
],
...
]各位朋友，怎么用js写个函数把它格式化一下。
