undefined when contract code is copied in Geth - ethereum

Question

I'm trying to create a contract in Ethereum private network.
What I tried was:
Created the following contract in browser-solidity.
pragma solidity ^0.4.19;
contract SingleNumRegister {
uint storedData;
function set(uint x) public {
storedData = x;
}
function get() public constant returns (uint retVal) {
return storedData;
}
}
And copied web3 deploy code as below.
var singlenumregisterContract =
web3.eth.contract([{"constant":false,"inputs":[{"name":"x","type":"uint256"}],"name":"set","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"get","outputs":[{"name":"retVal","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"}]);
var singlenumregister = singlenumregisterContract.new(
{
from: web3.eth.accounts[0],
data: '0x6060604052341561000f57600080fd5b60d38061001d6000396000f3006060604052600436106049576000357c0100000000000000000000000000000000000000000000000000000000900463ffffffff16806360fe47b114604e5780636d4ce63c14606e575b600080fd5b3415605857600080fd5b606c60048080359060200190919050506094565b005b3415607857600080fd5b607e609e565b6040518082815260200191505060405180910390f35b8060008190555050565b600080549050905600a165627a7a72305820cc0de7aa0d676f08b124d9f878aeecd0c305703a9d59ccde63b557dd8585dfcb0029',
gas: '4700000'
}, function (e, contract){
console.log(e, contract);
if (typeof contract.address !== 'undefined') {
console.log('Contract mined! address: ' + contract.address + ' transactionHash: ' + contract.transactionHash);
}
})
Then, copied in the console.

As above, I got undefined both scripts.
How can I solve this?
I use the environment below:
MacOSX 10.12.6
Geth: 1.7.3-stable
Solc: 0.4.19+commit.c4cbbb05.Darwin.appleclang

You need to JSON.parse() your ABI.
var jsonAbi = JSON.parse('[{"constant":false,"inputs":[{"name":"x","type":"uint256"}],"name":"set","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"get","outputs":[{"name":"retVal","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"}]');
var singlenumregisterContract = web3.eth.contract(jsonAbi);
