jsonオブジェクトを解析するJavascript

Question

javascriptを使用して次の（検証された）json文字列を解析しようとしています。私は次のコードを試しましたが、動作していないようです。

コード：

var obj = JSON.parse(data); 
alert(obj.Design_Lump_Sum[1]); 
alert(obj[1]); 

JSONオブジェクト：

 { 
    "Capex_Lump_Sum": 
    { 
    "Pipework and associated fittings": "86086.9", 
    "Cable Trays": "10410.4",

それはすでに有効なJSONであるとして、あなたはそれを解析する必要はありません。 var obj = JSON.parse(data);をとして直接あなたのオブジェクトにアクセスする - - ちょうど行を削除obj.Design_Lump_Sum['Electrical Services Design']
