arr = ["sp18", "su17", "sp19", "au16", "au18", "wi19"];
//字符串 'sp18' 表示18年春天
//按照 年限--季节 重新排序该数组
// 结果为 ['aut16','su17','sp18','au18','sp19','win19']
思路:先排序年限,再排序季节
总结 : 冒泡排序 + 数组的sort方法--自定义排序规则
arr = ["sp18", "su17", "sp19", "au16", "au18", "wi19"];
//字符串 'sp18' 表示18年春天
//按照 年限--季节 重新排序该数组
// 结果为 ['aut16','su17','sp18','au18','sp19','win19']
//规则函数
function abc(a, b) {
//规则
var season = ["sp", "su", "au", "wi"];
return season.indexOf(a.type) - season.indexOf(b.type);
}
//如果年限相等
switer = (a, b) => {
c = a.substr(0, 2);
d = b.substr(0, 2);
x = [c, d];
if ((c = d)) {
} else {
x.sort(abc);
let [a, b] = [...x];
}
};
//冒泡
for (let i = 0; i < arr.length - 1; i++) {
for (let i = 0; i < arr.length - 1; i++) {
console.log(arr[i].substr(2, 2));
a = arr[i].substr(2, 2);
b = arr[i + 1].substr(2, 2);
let x = 0;
if (a > b) {
x = arr[i];
arr[i] = arr[i + 1];
arr[i + 1] = x;
} else if ((a = b)) {
switer(arr[i], arr[i + 1]);
}
}
}
console.log();
