Json數據在node.js句柄中解析

表單API我有JSON數據，如下所示。我是node.js中的新成員，所以我不知道如何解析JSON數據。Json數據在node.js句柄中解析

[ 
    { 
    "Detail": " Rs. 1001 Full Talktime Topup Rs.1001 Full Talktime", 
    "Amount": "1001", 
    "Validity": "Unlimited" 
    }, 
    { 
    "Detail": " Rs. 1000 Full Talktime Topup Rs.1050 more than Full Talktime", 
    "Amount": "1000", 
    "Validity": "Unlimited" 
    }, 
    { 
    "Detail": " Rs. 899 Full Talktime Topup Rs.899 Full Talktime", 
    "Amount": "899", 
    "Validity": "Unlimited" 
    }, 
    { 
    "Detail": " Rs. 501 Full Talktime Topup Rs.501 Full Talktime", 
    "Amount": "501", 
    "Validity": "Unlimited" 
    }, 
    { 
    "Detail": " Rs. 500 Full Talktime Topup Rs.500 Full Talktime", 
    "Amount": "500", 
    "Validity": "Unlimited" 
    }, 
    { 
    "Detail": " Rs. 225 Full Talktime Topup Rs.225 Full Talktime", 
    "Amount": "225", 
    "Validity": "30 days" 
    }, 
    { 
    "Detail": " Rs. 59 Full Talktime Topup Rs.59 Full Talktime", 
    "Amount": "59", 
    "Validity": "7 days" 
    }, 
    { 
    "Detail": " Rs. 32 Full Talktime Topup Rs.32 Full Talktime", 
    "Amount": "32", 
    "Validity": "3 days" 
    } 
]

handlebars.registerHelper是

hbs.registerHelper("FTT", function(author){ 
    return JSON.stringify(code); 
});

和把手模板

{{#each FTT}} 
    <tr> 
     <td>Hello</td> 
     <td>{{FTT.[0].Detail}}</td> 
     <td>{{this.[0].Amount}}</td> 
     <td>{{Validity}}</td> 
    </tr> 
{{/each}}

在FTT不displaing什麼。我也嘗試不同的sugeestion，但仍然沒有獲得任何地方。任何sugession，

使用'JSON.parse（代碼）'，'JSON.stringify（代碼）'把它轉換成一個字符串。 –

我也試過，但每個都不是循環投擲FTT你可以建議任何活的例子 –

這裏有一個工作的例子，我希望這有助於：

$(function() { 
 
    var context = {}; 
 

 
    Handlebars.registerHelper('ftt', function(author) { 
 
    Object.assign(context, { 
 
     FTT: jsonData 
 
    }); 
 
    }); 
 

 
    var theTemplateScript = $("#ftt-html").html(); 
 
    var theTemplate = Handlebars.compile(theTemplateScript); 
 
    var theCompiledHtml = theTemplate(context); 
 

 
    $('.content-placeholder').html(theCompiledHtml); 
 

 
}); 
 

 

 
var jsonData = [{ 
 
    "Detail": " Rs. 1001 Full Talktime Topup Rs.1001 Full Talktime", 
 
    "Amount": "1001", 
 
    "Validity": "Unlimited" 
 
    }, 
 
    { 
 
    "Detail": " Rs. 1000 Full Talktime Topup Rs.1050 more than Full Talktime", 
 
    "Amount": "1000", 
 
    "Validity": "Unlimited" 
 
    }, 
 
    { 
 
    "Detail": " Rs. 899 Full Talktime Topup Rs.899 Full Talktime", 
 
    "Amount": "899", 
 
    "Validity": "Unlimited" 
 
    }, 
 
    { 
 
    "Detail": " Rs. 501 Full Talktime Topup Rs.501 Full Talktime", 
 
    "Amount": "501", 
 
    "Validity": "Unlimited" 
 
    }, 
 
    { 
 
    "Detail": " Rs. 500 Full Talktime Topup Rs.500 Full Talktime", 
 
    "Amount": "500", 
 
    "Validity": "Unlimited" 
 
    }, 
 
    { 
 
    "Detail": " Rs. 225 Full Talktime Topup Rs.225 Full Talktime", 
 
    "Amount": "225", 
 
    "Validity": "30 days" 
 
    }, 
 
    { 
 
    "Detail": " Rs. 59 Full Talktime Topup Rs.59 Full Talktime", 
 
    "Amount": "59", 
 
    "Validity": "7 days" 
 
    }, 
 
    { 
 
    "Detail": " Rs. 32 Full Talktime Topup Rs.32 Full Talktime", 
 
    "Amount": "32", 
 
    "Validity": "3 days" 
 
    }
