Assuming you want the elements listed in alphabetical order by their value:
假设您希望元素按其值按字母顺序列出：
var values = [];
for(var i in json.message) {
values.push(json.message[i]);
}
var str = values.sort().join('\n');
Update

To form an array of key-value pairs ordered by their (string) value:
要形成按（字符串）值排序的键值对数组：
var values = [];
for(var i in json.message) {
values.push({ key: i, value: json.message[i] });
}
values.sort(function(a, b) { return a.value.localeCompare(b.value); });
var str = values.map(function (kvp) { return kvp.value; }).join('\n');

var message = object.message;
var brands = Object.keys(message)
.map(function(key) { return message[key]; })
.sort();
alert(brands.join('\n'));

using JS library undescore.js is pretty easy, just do:
使用 JS 库 undescore.js 非常简单，只需执行以下操作：
json.message=_.sortBy(json.message,function(i){return i;})

You can sort it by this way, this is a sort basied on values :
您可以通过这种方式对其进行排序，这是一种基于值的排序：
function sortJsonMap(data){
var values = [];
var keys = [];
for(var i in data) {
keys.push(i);
values.push(data[i]);
}
values.sort();
var map = new Object();
for(var i in values) {
map[keys[i]]=values[i];
}
return map;
}
}

Add a leading 0 to each index. For example:
为每个索引添加一个前导 0。例如：
var json = {
"message": {
"090": "Adidas",
"02": "Armani",
"089": "Casio",
"01": "Diesel",
...
