JavaScript数组排序实战：利用sort与localeCompare按字母顺序排列

array（数组）.sort(function (s1, s2) {
    let a1 = s1.toUpperCase();
    let a2 = s2.toUpperCase();
    if (a1 < a2) {
        return -1;
    }
    if (a1 > a2) {
        return 1;
    }
    return 0;
}

var arr1 = [
    {name: 'DaLin'},
	{name: 'HaLin'},
	{name: 'VaLin'},
	{name: 'SaLin'},
	{name: 'WaLin'},
	{name: 'EaLin'},
	{name: 'TaLin'},
	{name: 'YaLin'},
	{name: 'JaLin'}
]

// 根据英文首字母进行排序
arr1.sort(function(a, b) {
	return (a.name + '').localeCompare(b.name + '')
})
console.log(arr1)

// 根据英文首字母进行排序
arr1.sort(function(a, b) {
	return (b.name + '').localeCompare(a.name + '')
})
console.log(arr1)
