unescape ajax响应数据中的特殊字符 [英] unescape special characters in ajax response data

问题描述

我有一个带有dataType的ajax请求：'json'

I have an ajax request with dataType: 'json'

收到的json（格式正确）包含转义换行符的字符串

The json received (being well formed) contains strings with newlines escaped

即'{a：x \\\\\\ nxx}'

遗憾的是，ajax done函数中的结果数据对象现在还包含该格式的换行符（\\\\\\ n）

unfortunately the resultant data object in the ajax done function now also contains the newline in that form ("\\r\\n")

我希望ajax结果数据对象中的所有字符串字段都不转义，这样在这种情况下我会得到

I want all string fields in the ajax result data object to be unescaped so that in this case I will get

data = {a：xNEWLINEx}

是否有一般这样做的方法？假设数据可能有嵌套数组和字典，每个字典包含可以有换行符（或其他转义特殊字符）的字符串

Is there a general way to do this ? assume data may have nested arrays and dictionaries each containing strings which can have newlines (or other escaped special characters)

推荐答案

建立在来自yangguang的回复，这是一个完整的解决方案：

Building on the response from yangguang, here is a complete solution:

    // 'unescape' all special characters in all strings in an object that was created from JSON (ie, ajax reply) 
    function jUnescape(obj) {
       var j = JSON.stringify(obj);
       ['b', 'f', 'n', 'r', 't', 'u'].forEach(function(c) {
          j=j.split('\\\\' + c).join('\\' + c);
       });
       j = j.split('\\\\\\"').join('\\"');
       j = j.split('\\\\\\\\').join('\\\\');
       return JSON.parse(j);
    }
