    javascript - How to remove brackets from JSON - Stack Overflow

    programmeradmin6浏览0评论

    I have this JSON data:

    var tmpStr = '[    
{
    "Name": "TEST",
    "deviceId": "",
    "CartId": "",
    "timestamp": 1383197265540,
    "FOOD": [],
    "City": "LONDON CA"
 }

]';

    How can I delete the brackets?

    Here is more of my JSON file:

    [{"arrivee":false,"des":"Ceintures De Sécurité Conducteur","code":"nn","depart":true},
 {"arrivee":true,"des"‌​‌​:"Lecteur Tachygraphe","code":"nn","depart":false}
 {"arrivee":false,"d‌​‌​es":"Ceintures De Sécurités Passagères","code":"nn","depart":true},
 {"arrivee":true,"des"‌​‌​:"Climatisation","‌​co‌​de":"nn","depart‌​":fa‌​lse}]

    Reset to default 3

    Parse the JSON string and use the first element of the array.

    var tmpStr = '[{"Name": "TEST","deviceId": "", "CartId": "", "timestamp": 383197265540, "FOOD": [], "City": "LONDON CA" }]',
    object = JSON.parse(tmpStr)[0];

console.log(object);
    .as-console-wrapper { max-height: 100% !important; top: 0; }

    You dont have to delete brackes, just do this,

    var result = tmpStr[0];

    Description:
    You wouldn't want to, this is a JSON array of Objects

    [ // this starts an array
    { // this starts an object
        "Name": "TEST", // this is a property named 'Name'
        "deviceId": "", // this is a property named 'deviceId'
        "CartId": "", // this is a property named 'CartId'
        "timestamp": 1383197265540, // this is a property named 'timestamp'
        "FOOD": [], // this is a property named 'FOOD'
        "City": "LONDON CA" // this is a property named 'City'
    } // this ends an object
] // this ends an array
