JavaScript 字符串单引号双引号相互替换

let params = {"type":"survey_1","option1":"6","option2":"Yes","option3":"6","option4":"how"}

let str = JSON.stringify(params).replace(/"/g, '\'')

console.log(str)

{'type':'survey_1','option1':'6','option2':'Yes','option3':'6','option4':'how'}

let params = {"type":"survey_1","option1":"6","option2":"Yes","option3":"6","option4":"sasdasd"}

let str = JSON.stringify(params).replace(/"/g, '\\"')

console.log(str)

结果：{\"type\":\"survey_1\",\"option1\":\"5\",\"option2\":\"No, It took multiple attempts\",\"option3\":\"5\",\"option4\":\"asdasda\"}

JSON.stringify(params).replace(/'/g, '"') 没有亲测
