尝试从对象中输出响应消息

Here is my error callback function from an ajax call.

这是来自ajax调用的错误回调函数。

error: function(xhr, status, error) {
    var responseObj = jQuery.parseJSON( xhr.responseText );
}

From that I am sending this to the console:

我把这个发给控制台:

console.log(responseObj.message);

Which is returning this:

这是返回:

Object {Invalid or missing parameters: Object}
    Invalid or missing parameters: Object 
        email_already_in_use: "'Email' already in use"

If I stringify the response like this:

如果我像这样压缩响应:

var responseMsg = responseObj.message;
if(typeof responseMsg =='object') {
    var respObj = JSON.stringify(responseMsg);
    console.log(respObj);
}

I get this:

我得到了这个:

{"Invalid or missing parameters":{"email_already_in_use":"'Email' already in use"}}

How can I print to the user that their email is already in use?

我如何向用户打印他们的电子邮件已经在使用?

complete callback function:

完整的回调函数:

error: function(xhr, status, error) {

    var responseObj = jQuery.parseJSON( xhr.responseText );
    var responseMsg = responseObj.message;

    if(typeof responseMsg =='object') {

        var respObj = JSON.stringify(responseMsg);
        console.log(respObj);

    } else {

        if(responseMsg ===false) {

            console.log('response false');

        } else {

            console.log('response something else');

        }
    }
      console.log(responseObj.message);
}

You could do something like this:

你可以这样做:

var errorMessages = responseObj.message["Invalid or missing parameters"];

for (var key in errorMessages) {
  if(errorMessages.hasOwnProperty(key)){
    console.log(errorMessages[key]);
  }
}

If you have different kinds of messages (not only "Invalid or missing parameters"), you should iterate the message array first:

如果您有不同类型的消息(不仅是“无效或缺失的参数”)，您应该首先迭代消息数组:

var errorMessages = responseObj.message;
for (var errorType in errorMessages){
  if(errorMessages.hasOwnProperty(errorType)){
    console.log(errorType + ":");
    var specificErrorMsgs = errorMessages[errorType];
    for (var message in specificErrorMsgs) {
      if(specificErrorMsgs.hasOwnProperty(message)){
        console.log(specificErrorMsgs[message]);
      }
    }
  }
}
