我有json对象，想要根据variablevalue对整个json对象进行排序。
的JSONObject：

我尝试过功能
function sortByKey(array, key) {
return array.sort(function(a, b) {
var x = a[key]; var y = b[key];
return ((x > y) ? -1 : ((x < y) ? 1 : 0));
});
}
但它仅返回内部json对象并错过主节点文本，如：
{
"variablevalue":{
"color":"Blue",
"y":204400.0
},
"variablename":"Employment, 2014 (persons)"
},
{
"variablevalue":{
"color":"Black",
"y":198300.0
},
"variablename":"Projected
Employment, 2024 (persons)"
}
所以排序后的最终结果如下：
"Surveyors, Cartographers, and Photogrammetrists":[
{
"variablevalue":{
"color":"Blue",
"y":204400.0
},
"variablename":"Employment, 2014 (persons)"
},
{
"variablevalue":{
"color":"Black",
"y":198300.0
},
"variablename":"Projected
Employment, 2024 (persons)"
}
}
请帮帮我。
答案 0 :(得分：0)
假设您希望按variablevalue.y值按降序排序，而且永远不会null或undefined。
试
obj["Surveyors, Cartographers, and Photogrammetrists"].sort(function(a,b){
return parseFloat(b.variablevalue.y) - parseFloat(a.variablevalue.y);
});
如果variablevalue.y可以是null，undefined或NaN那么
obj["Surveyors, Cartographers, and Photogrammetrists"].sort(function(a,b){
var by = !isNaN(parseFloat(b.variablevalue.y)) || 0;
var ay = !isNaN(parseFloat(a.variablevalue.y)) || 0;
return by - ay;
});
