JSON.parse解决Unexpected token ' in JSON at position 1报错
JSON.parse解决Unexpected token ' in JSON at position 1报错
壹 ❀ 引
我们知道JSON.parse能将JSON字符串转变成JS对象,但在一些转换中可能出现Unexpected token ' in JSON at position 1的错误,这是因为被转换的值不符合JSON格式而造成的。
JSON官方明确规定,JSON数据的key与value必须使用双引号""包裹,否则在转换过程中会导致错误。
A value can be a string in double quotes, or a number, or true or false or null, or an object or an array. These structures can be nested.
A string is a sequence of zero or more Unicode characters, wrapped in double quotes, using backslash escapes. A character is represented as a single character string. A string is very much like a C or Java string.
贰 ❀ 示例
// 数组 let a = '["a","b","c"]';// √ let b = "['a','b','c']";// X // 对象 let a1 = '{"name":"听风是风","age":"26"}';// √ let b1 = "{'name':'听风是风','age':'26'}";// X console.log(JSON.parse(a))// Array console.log(JSON.parse(a1))// Object console.log(JSON.parse(b))// 报错 console.log(JSON.parse(b1))// 报错
