javascript - React 中的 JSON 对象解析问题

Question

json = "{ elements: [ {type: 'radiogroup', choices: ['Yes','No','Maybe','Never'], isRequired: true, name: 'Test_01', title: 'Do you like ice cream?' }],showQuestionNumbers: 'off'}";  
   json = JSON.stringify(json);
   model = new Model(json);

它不识别带有引号的 json 对象

 var json = "{ elements: [ {type: 'radiogroup', choices: ['Yes','No','Maybe','Never'], isRequired: true, name: 'Test_01', title: 'Do you like ice cream?' }],showQuestionNumbers: 'off'}";

删除引号时有效

   json = { elements: [ {type: 'radiogroup', choices: ['Yes','No','Maybe','Never'], isRequired: true, name: 'Test_01', title: 'Do you like ice cream?' }],showQuestionNumbers: 'off'}; 

我试过 JSON.parse(json);它不起作用，有人可以建议解决方案吗？

如果字符串中有 JSON，那么您应该执行 JSON.parse，而不是 JSON.stringify。

此外，单引号在 JSON 中是无效的，因此始终使用双引号。

// I fixed the JSON
var json = '{ elements: [ {type: "radiogroup", choices: ["Yes","No","Maybe","Never"], isRequired: true, name: "Test_01", title: "Do you like ice cream?" }],showQuestionNumbers: "off"}';
// The thing you would expect
var obj = JSON.parse(json);
