分享一个json字符串转换方法

function json2str(o) {
var arr = [];
var fmt = function(s) {
if (typeof s == ‘object‘ && s != null) return json2str(s);
return /^(string|number)$/.test(typeof s) ? ‘"‘ + s + ‘"‘ : s;
}
for (var i in o) arr.push("‘" + i + "‘:" + fmt(o[i]));
return ‘{‘ + arr.join(‘,‘) + ‘}‘;
} 

//json2str({a:1,sd:3})
//"{‘a‘:"1",‘sd‘:"3"}"
