Question

我有一个像下面这样的json字符串

[

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

]

我想从字符串中删除/删除第一个和最后一个方括号。那么如何使用javascript从上面的字符串中删除第一个和最后一个方括号。

请帮帮我

Answer 1

返回时使用此项：

return properties[0];

或者

var data = [

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

]; // Or whatever the Json is
data = data[0];

或者，如果您通过其他对象访问json

var data = jsonObj[0];

Answer 2

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

]';

var newStr = tmpStr.substring(1, tmpStr .length-1);

Answer 3

试试这个：

var A = [{}]; var B = {}; A = [

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

]

B = A[0]; console.log(B); //required output
