处理JSON响应单个字符串 [英] Process JSON response single string

问题描述

我在php中有一个看起来像这样的json

I have json that looks like this in php

json_encode('Test string');

它发送回字符串，我用萤火虫检查过. 我如何访问它?

it sends the string back i checked with firebug. how can i access it?

 success: function(theResponse) {           

           alert()

    }  

我应该在警报中添加什么以获取该字符串?

what should i put inside alert to get that string?

推荐答案

即使输出为单个字符串，也应将其格式设置为有效的JSON:

You should format your output as valid JSON even if it's single string:

json_encode(array("message" => "No Return Email Address Specified!"));

然后您可以像这样在JS中访问它:

Then you can access it in JS like this:

 success: function(theResponse) {           

       alert(theResponse.message)

}
