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?functions*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：

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