Question

我有一个JSON，如果值是1，我想将FUTURE_CALL转换为true，0则返回false。

我该怎么做？我的示例不起作用。

var tickets = '{tickets: {
   "Tickets": [
      {
         "TICKET_ID": "",
         "TITLE": "",
         "DESCRIPTION": "",
         "CREATION_DATE": "",
         "COMPLETION_DATE": "",
         "CREATED_BY": "",
         "FUTURE_CALL": "",
         "TICKET_PRIORITY_DESCRIPTION": "",
         "TICKET_PRIORITY_CODE": "",
         "TICKET_CATEGORY_DESCRIPTION": "",
         "TICKET_CATEGORY_CODE": "",
         "TICKET_TYPE_CODE": "",
         "TICKET_TYPE_DESCRIPTION": "",
         "TICKET_TAG_CODE": "",
         "TICKET_TAG_DESCRIPTION": "",
         "TICKET_STATUS_CODE": "",
         "TICKET_STATUS_DESCRIPTION": "",
         "DUE_DATE": "",
         "ACCOUNT_ID": ""
      }
   ]
}}';

var updatedTickets = tickets;
for(var i = 0; i < updatedTickets.tickets['Tickets'].length; i++) {
     if(updatedTickets[i].tickets['Tickets'].FUTURE_CALL == 1) {
        updatedTickets[i].tickets['Tickets'].FUTURE_CALL = true;
     }
}

Answer 1

首先，您的代码中存在一个小问题：

updatedTickets[i].tickets['Tickets']

updatedTiclets是一个对象，其tickets['Tickets"]是一个数组，因此您必须：

updatedTickets.tickets['Tickets'][i]

然后您的比较应该可以进行，但是最简单的方法就是将其转换为数字：

if( +updatedTickets.tickets['Tickets'][i].FUTURE_CALL)

这将起作用，因为0是虚假的，而1是真实的。

var updatedTickets = tickets;
for(const ticket of updatedTickets.tickets['Tickets']) k
 ticket.FUTURE_CALL =
     ticket.FUTURE_CALL === "1";        
}

Answer 2

起初，您没有验证JSON –必须编写{"tickets":而不是{tickets:（就像您的代码一样）。
然后，您必须使用JSON.parse来解析JSON。
然后，如果要在一个字符串中写入反斜杠，则必须在JSON字符串的每一行中使用反斜杠。
updatedTickets[i].tickets['Tickets']是错误的。您必须写updatedTickets.tickets['Tickets'][i]。

我更正了您的代码：

var tickets = '{"tickets": {\
    "Tickets": [\
    {\
        "TICKET_ID": "",\
        "TITLE": "",\
        "DESCRIPTION": "",\
        "CREATION_DATE": "",\
        "COMPLETION_DATE": "",\
        "CREATED_BY": "",\
        "FUTURE_CALL": "",\
        "TICKET_PRIORITY_DESCRIPTION": "",\
        "TICKET_PRIORITY_CODE": "",\
        "TICKET_CATEGORY_DESCRIPTION": "",\
        "TICKET_CATEGORY_CODE": "",\
        "TICKET_TYPE_CODE": "",\
        "TICKET_TYPE_DESCRIPTION": "",\
        "TICKET_TAG_CODE": "",\
        "TICKET_TAG_DESCRIPTION": "",\
        "TICKET_STATUS_CODE": "",\
        "TICKET_STATUS_DESCRIPTION": "",\
        "DUE_DATE": "",\
        "ACCOUNT_ID": ""\
    }]\
}}';

var updatedTickets = JSON.parse(tickets),
	ticketsObj = updatedTickets.tickets['Tickets'];

for(var i = 0; i < ticketsObj.length; i++)
    // symbol "+" convert string to integer
	ticketsObj[i].FUTURE_CALL = +ticketsObj[i].FUTURE_CALL == 1 ? true : false;

console.log(JSON.stringify(updatedTickets, null, '\t'));

Javascript-将1转换为true（带有示例）
