在我的情况下，如何从Json Stringify读取值? [英] How to read the value from Json Stringify in my case?

问题描述

我验证用户登录后，如果登录失败，则会显示以下错误消息

After I validate user login, if it failed it will show the following error message

jquery

console.log('Full error  = ' + JSON.stringify(showError));
console.log('test 1 =' + showError.responseText);

错误消息

Full error  = {"readyState":4,"responseText":"{\"error\":\"invalid_grant\",\"error_description\":\"The user name or password is incorrect.\"}","responseJSON":{"error":"invalid_grant","error_description":"The user name or password is incorrect."},"status":400,"statusText":"Bad Request"}


test 1 ={"error":"invalid_grant","error_description":"The user name or password is incorrect."}

我只想显示The user name or password is incorrect条消息

推荐答案

您必须解析responseText属性，因为它是JSON字符串.

You have to parse the responseText property since it's a JSON string.

console.log(JSON.parse(showError.responseText).error_description);

// or using bracket notation
console.log(JSON.parse(showError.responseText)['error_description']);

var showError = {"readyState":4,"responseText":"{\"error\":\"invalid_grant\",\"error_description\":\"The user name or password is incorrect.\"}","responseJSON":{"error":"invalid_grant","error_description":"The user name or password is incorrect."},"status":400,"statusText":"Bad Request"} ;

console.log(JSON.parse(showError.responseText).error_description);
