JS中根据某个值进行大小排序

//从大到小排序
function compareBigToSmall(property){return function(a,b){var value1 = a[property];var value2 = b[property];return  value2 - value1;}
};
//从小到大排序
function compareSmallToBig(property){return function(a,b){var value1 = a[property];var value2 = b[property];return   value1-value2;}
};

arr.sort(compareBigToSmall('balance'));//从大到小排序
