I have got a simple select menu containing all countries with their city's listed in respective option value.
The value also contains some other data, for instance Canadahas value +1|}|22|Xwhile United Stateshas this +1|}|128|X||{|58$Abilene#|{|59$Akron#|{|1$Alabama#|{|2$Alaska#|{|60$Albany#|....

I need to fill another select menu on change of country select menu. I can't figure out how can i parse each city listed in the country's value.
我需要在更改国家/地区选择菜单时填写另一个选择菜单。我不知道如何解析该国家/地区值中列出的每个城市。

Maybe try this, idk, that data was kind of weird:
也许试试这个，idk，那个数据有点奇怪：
$('#country_residence').on('change', function () {
var cities = $(this).val().split('$');
$("#cities option").remove();
for(var i = 1;i<cities.length;i++)
{
var city = String(cities[i]);
if(city.indexOf("#")>-1)
city = city.substring(0,city.indexOf("#"));
$("#cities").append("<option>" + city + "</option>");
}
});

Ifthere was absolutely no other way to get cleaner data? I'd do some (albeit somewhat brain-melting) regular expression matching on the server side to filter the information and then parse it into a usable list for use with JSON.
如果绝对没有其他方法可以获得更干净的数据？我会在服务器端做一些（虽然有点费脑筋）正则表达式匹配来过滤信息，然后将它解析成一个可用的列表以与 JSON 一起使用。
I, for one, would not attempt to do this on the client side.
一方面，我不会尝试在客户端执行此操作。
