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：

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?function\s*toString\(\)\s*\{\n?\s*\[native code\]\n?\s*\}\n?\s*$/.test(o.toString)) {

                    r.push("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：

var str2="菜鸟教程(cainiaojc.com),www.cainiaojc.com,脚本下载,百度,456,456,456"; 

var arr1=str2.split(","); 

alert(arrayToJson(arr1));
