js打造数组转json函数

代码很简单，这里就不多废话了，直接奉上：

复制代码 代码如下:
function arrayToJson(o) {
        var r = [];
        if (typeof o == "string") return "\"" + o.replace(/([\'\"\\])/g, "\\$1").replace(/(\n)/g, "\\n").replace(/(\r)/g, "\\r").replace(/(\t)/g, "\\t") + "\"";
        if (typeof o == "object") {
            if (!o.sort) {
                for (var i in o)
                    r.push(i + ":" + arrayToJson(o[i]));
                if (!!document.all && !/^\n"toString:" + o.toString.toString());
                }
                r = "{" + r.join() + "}";
            } else {
                for (var i = 0; i < o.length; i++) {
                    r.push(arrayToJson(o[i]));
                }
                r = "[" + r.join() + "]";
            }
            return r;
        }
        return o.toString();
    }

作用相当于  JSON.stringify(array);

简单用法：

复制代码 代码如下:
var str2=",www.jb51.net,脚本下载,百度,456,456,456";
var arr1=str2.split(",");
alert(arrayToJson(arr1));
