按首字母排序汉字

一、前端 js 处理

var a = ["上海","大连","北京","拉萨","天津"];

//返回["北京", "大连", "拉萨", "上海", "天津"]
a.sort(function(a,b){return a.localeCompare(b)});

localeCompare

定义和用法

语法

stringObject.localeCompare(target)

返回值

var a = [
{name: 'a', phone: 1, value: "上海"},
{name: 'b', phone: 5, value: "大连"},
{name: 'd', phone: 3, value: "北京"},
{name: 'c', phone: 4, value: "拉萨"}
];

a.sort(function(a,b){
return a.value.localeCompare(b.value)
});

二、后台 php 处理

foreach ($array as $key=>$value)  {
$new_array[$key] = iconv('UTF-8', 'GBK', $value);
}
asort($new_array);
foreach ($new_array as $key=>$value)  {
$array[$key] = iconv('GBK', 'UTF-8', $value);
}
