js 删除数组中的项

//根据判定删除数据 返回的是去掉的部分
    this.removed = function (o,judge,param ) {       
        if (o.constructor == Array && judge) {
            if (judge.constructor == String) {
                judge = judge.replace(/\*./g, 'a.');
                judge = judge.replace(/@/g, 'param.');
                judge = judge.replace(/param.param./g, '@');
                var re = [];
                for (var i = 0, a; a = o[i++];) {
                    if (eval(judge)) {
                        re.push(o.splice(--i, 1)[0]);
                    }
                }
                return re;
            } else if (judge.constructor == Function) {
                var re = [];
                for (var i = 0, a; a = o[i++];) {
                    if (judge(a)) {
                        re.push(o.splice(--i, 1)[0]);
                    }
                }
                return re;
            }

        }

    }
