试过

        Array.prototype.associate = function (keys) {
            var result = {};

            this.forEach(function (el, i) {
                result[keys[i]] = el;
            });

            return result;
        };
        var customerId = arr2;
        var customerName = arr3;
        console.log(customerId.associate(customerName));
        console.log(Object.keys(arr));
        //document.getElementById(customerId.associate(customerName));

解决

 array3 = [];
            console.log(arr2);
            arr2.forEach(function (e, i) {
                array3.push(
                  [e] + ":" + arr3[i]
                );
            })

            document.write(JSON.stringify(array3));
