Question

Hello Everyone，我无法从本地json文件中获取项目作为NodeJs中的值和键。

[
{
"question":"What is the first name of your best friend in high school?",
"answer":"U2FsdGVkX18/l/UF1DbqMp9ItOqgmmQIeVUlxqrb7vE="},
{
"question":"What was your childhood nickname?",
"answer":"U2FsdGVkX1+x14bgpnjr3UcvScBDbIOnP55vua2NvME="},
{
"question":"What is the name of the street you grew up in?",
"answer":"U2FsdGVkX1+pGkO/MRIP7oHym3Ynz/7n/fYuEt7fTFw="}]

这是本地json文件。我如何获取问题和答案并将其保存到不同的阵列。提前致谢。

Answer 1

var data = [
{
    "question":"What is the first name of your best friend in high school?",
    "answer":"U2FsdGVkX18/l/UF1DbqMp9ItOqgmmQIeVUlxqrb7vE="},
{
    "question":"What was your childhood nickname?",
    "answer":"U2FsdGVkX1+x14bgpnjr3UcvScBDbIOnP55vua2NvME="},
{
    "question":"What is the name of the street you grew up in?",
    "answer":"U2FsdGVkX1+pGkO/MRIP7oHym3Ynz/7n/fYuEt7fTFw="
}];

var data = JSON.parse(data); 
var questions = data.map(current =>  current.question);
var answers = data.map(current => current.answer);

Answer 2

假设您的本地数据文件位于data.json，您可以使用它，如下所示。

var data = require('./data.json')
console.log(data[0]);

Answer 3

如果你想从文件系统中读取你的json文件，那就是：

$scope.requestedLeaveTypeCount=[2,2,2,2]

从节点js中的本地Json文件中获取值和键
