截取前面的wjr( 和后面的),然后用JSON.parse转化为json对象

function wjr(data){
 //data就是一个json对象
}
eval(返回值)

还是我自己来解析吧； 这个不是使用的JSON，而是使用的JSONP方式传回的值。 什么是JSONP： http://victor-jan.iteye.com/blog/875061

用 jquery.ajax 的 jsonp 形式去用这接口

JSON.parse(String) 和 JSON.stringify(Object) 可以解析一切字符串和反解析js对象（function除外）。

带换行的字符串没办法的用 JSON.parse 解析。

@think2011 纯粹是胡扯。 换行的字符是\n \r\n,都是字符。 C语言第1课就讲什么是字符。

@tulayang 抱歉，我表述的有问题。 我实践的案例中，前端发出了带换行的字符串（通过:textarea，由用户输入）到后端（c#）保存。 后端再输出给前端，输出的数据如果没有处理，大概是这样的。 JSON:

 {
msg: "
1. 打扫卫生
2. 吃饭
"
}

这个时候，JSON.parse无法解析。

@think2011 JSON.parse（）可以解析。 从原理上，http传送的数据，是

"{\nmsg:\"\n1.打扫卫生\n2.吃饭\n\"\n}"

JSON.parse()解析出来是

{
    msg: "\n1.打扫卫生\n2.吃饭\n"
}

你如果没有获得期望的格式，那就是你的字符转换不正确。

@tulayang 是的，明白了，从抓包的数据来看，在发送到后端前数据是已经经过处理的。 而我的案例中出现问题，是后端没有正确处理字符串，与JSON.parse无关。
