ajax 转json,求问一个关于AJAX返回的JSON数据转换处理的问题

现有如下AJAX返回的JSON数据

result: Array(15)

0: {companystyle: "caa", userVipOnlineCount: 59}

1: {companystyle: "cab", userVipOnlineCount: 756}

2: {companystyle: "cac", userVipOnlineCount: 100}

3: {companystyle: "cad", userVipOnlineCount: 170}

4: {companystyle: "caf", userVipOnlineCount: 49}

5: {companystyle: "cag", userVipOnlineCount: 21}

6: {companystyle: "caj", userVipOnlineCount: 6}

7: {companystyle: "cak", userVipOnlineCount: 26}

8: {companystyle: "cam", userVipOnlineCount: 1066}

9: {companystyle: "can", userVipOnlineCount: 2077}

10: {companystyle: "cao", userVipOnlineCount: 7}

11: {companystyle: "cap", userVipOnlineCount: 9}

12: {companystyle: "cas", userVipOnlineCount: 11}

13: {companystyle: "cau", userVipOnlineCount: 3}

14: {companystyle: "test", userVipOnlineCount: 7}

如何转换成如下格式的

var companystyle = ["caa","cab","cac","cad",.......];

var userVipOnlineCount = [59,756,100,170......];
