Werte aus der verschachtelten JSON-Liste extrahieren

Question

Wie kann ich JavaScript erhalten, um die Werte "am Ende" der JSON-Liste unten zu lesen. Ich bin derzeit den Code unten, mit der Ausnahme, dass dieser Code nicht die letzten drei Werte liest, mit unterschiedlichen Formatierungen, von der Liste unten dh

Auszug aus Json Liste:

{.. .... 'Design_Lump_Sum': {0: {'** Vorläufiges Design': '2366. 0 '}, 1: {' ** Detailliertes Design ': '15.379,0'}, 2: {' ** Konst Bühnen Services: '4732,0'}}}

Code:

var obj = JSON.parse(data); 
var keys = Object.keys(obj.Design_Lump_Sum); 
for (var asset in keys) { 
    console.log(asset + " -> " + keys[asset] + " = " + obj.Design_Lump_Sum[keys[asset]]); 
    } 
var keys1 = Object.keys(obj.Capex_Lump_Sum); 
for (var asset in keys1) { 
    console.log(asset + " -> " + keys1[asset] + " = " + obj.Design_Lump_Sum[keys1[asset]]); 
    } 
var keys2 = Object.keys(obj.Opex_Lump_Sum); 
for (var asset in keys2) { 
    console.log(asset + " -> " + keys2[asset] + " = " + obj.Design_Lump_Sum[keys2[asset]]); 
    } 
var keys3 = Object.keys(obj.Provisional_Sum); 
for (var asset in keys3) { 
    console.log(asset + " -> " + keys3[asset] + " = " + obj.Design_Lump_Sum[keys3[asset]]); 
    } 
var keys4 = Object.keys(obj.Management_fees); 
for (var asset in keys4) { 
    console.log(asset + " -> " + keys4[asset] + " = " + obj.Design_Lump_Sum[keys4[asset]]); 
    } 
var keys5 = Object.keys(obj.CSA); 
for (var asset in keys5) { 
    console.log(asset + " -> " + keys5[asset] + " = " + obj.Design_Lump_Sum[keys5[asset]]); 
    }

Wenn ich Ihre Frage nicht falsch verstanden haben, dann können Sie wie folgt versuchen.

var obj={'Management_fees':{},'Capex_Lump_Sum':{'Refrigerant piping':'48040.447','Preparation of Mops':'2137.681','Labels':'653.016','Penetrations and Protection':'1535.534','AC Plinth and Trays':'5221.762','Insulated Panel Windows':'6527.794',' MSSB':'19582.199','Make Good Walls and Floors':'4154.696','Controls':'24092.978','** Building Surveyor Fee (Misc)':'7038.85','Project Manag ement, Supervision':'38447.5','Painting':'9138.675','Preliminaries':'1306.032','Package system wiring':'16971.318','Warranty':'2610.881','Ductwork, Valves and Dampers':'77262.913','Unit ty pe':'89107.109','Structural Engineer for new unit stands':'3916.913','Manuals':'3823.456','AMS and BMS works':'3916.913','Accoustic Report':'4243.421','Lighting':'5033.665','Drawings':'38 23.456','Temp Cooling':'10443.524','Commissioning':'3263.897','Crane':'3003.637','Demolition':'26455.429','Fire detection and Alarm FIP modifications':'3263.897','LSL':'1939.81059657','Ec onomy Cycle':'23169.055'},'Provisional_Sum':{'Condenser Roof Platform':'20000.0','Removal of ladder outside cable chamber exit stairs':'10000.0'},'Opex_Lump_Sum':{},'CSA':{'Additional Hendry Fees':'3742.5','External Ladder':'10147.0','Asbestos removal Works Total ($42,485.15) (remainder of cost $30K under PS sum)':'12485.15'},'Design_Lump_Sum':{0:{'** Preliminary Design':'2366. 0'},1:{'** Detailed Design':'15379.0'},2:{'** Const Stage Services':'4732.0'}},'Total':{'sub_Total':'number:530154.0105965699'}}; 
 

 
var data = obj.Design_Lump_Sum; 
 

 
Object.keys(data).map(function(item,index){ 
 
    Object.keys(data[item]).map(function(key) { 
 
    console.log(key, "->", data[item][key]); 
 
    }); 
 
});
