js如何根据数组某个值进行排序？

var arr =[{"districtCode":"440106","address":"大街","province":"湖南省","city":"长沙市","district":"雨花区","name":"总店","id":300004,"isDefault":false},{"districtCode":"440106","address":"露露路路","province":"广东省","city":"广州市","district":"天河区","name":"服务店","id":300003,"isDefault":true}]

arr.sort(getSortFun('desc', 'isDefault'));
