Country list choice, then what?

[LilaDunc]

I'm new so please excuse my lack of savy. I first came to the Code Project site because I wanted to learn JavaScript but I dont know if this is really a js task. I've found some HTML code for a drop down list where a user can choose their country. Example: ==================== Country... Afghanistan ======================= How can I get any country selected from the list to be associated with one of five world postage zones and the user taken to a page of information related to that zone? I'd be grateful for any advice on this or pointers to information. Regards and best wishes, Lila Duncan

You don't say what your backend server technology is, so this is going to be generic. When the user submits this page back to the server, the server can have a lookup mechanism where it will look up the country and see what postal zone it is in. The lookup may be an in memory table of somesort, or it may be a database lookup and so on. Once the server knows the postal zone it can redirect the user to the appropriate page.

There is little backend server technology that I have any significant access to or control of, other than what I can set up within the basic web space provided by my ISP as a part of my ADSL subscription. I was hoping that the process could be handled from there, or even more usefully within the code of the pages themselves. If not, the process I'm trying to set up will be outside my scope for a while yet :-) If I already have javascript on my pages that can call a file from a remote location depending on what choice someone browsing the page makes, then it seems possible that a user could, by similar methods, make a choice from a list populated by a hundred options, which then calls one of 4 possible explanatory html pages from my web-space. Trouble is, if such a possibility exists, I don't yet know how to achieve it. Hence my original question. :-) Regards and best wishes, Lila Duncan

You have a list of countries...and when any of those countries is selected you want to redirect to an HTML page for the zone in which that country falls under???

<select onchange="location.href='"+this.options[this.selectedIndex].value+".html'">
<option>Country...<option/>
<option value="zone_1">Canada<option/>
<option value="zone_1">USA<option/>
<option value="zone_3">UK<option/>
</select>

What this code is doing: Whenever a option is selected the onchange event is fired and a redirection takes place. The code assumes you have the 5 global postal zones saved as HTML files, such as: zone_3.html that is why the value of each option for that country is zone_1, etc...in the above example I assume that Canada and the US are the same postal zone??? HTH Cheers :) It's frustrating being a genius and living the life of a moron!!!

If you don't need the country name anymore, you can set value=Zone instead of the country name. Then bring up the associated page matching the Zone value. [edit] ...errr... what Hockey said :rolleyes: [/edit] BW

Drop down lists only return a value, which in your case is the country name, so any extra information like the postage zone should be included in the value, and extracted from there. for example , Suppose that Afghanistan is in the postage region 1 an Albania in region 2 your list will look something like: Country... Afghanistan Afghanistan then get the selected value and do some string manipulations like SubString to separate the Postage zone value from the country name, if you're using .NET you can use SPLIT("_") and you'll get an array of two items, the first Item includes the zone ID and the second contains the name.

Yes, that's more or less it. Probably a little more but I need to take it one step at a time. Thankfully the solution you suggest seems at first glance to be within my current range of comprehension. This gives me hope that I'll be able to solve the problems associated with my little project, thanks to the help you've offered. Very kind of you, thanks a lot.:-) Regards and best wishes, Lila Duncan

This seems like the sort of modification that I could cope with. Thanks very much for the advice. Regards and best wishes, Lila Duncan

I'll try it and see how I manage. I don't usually mention taglines but yours made me feel sad. I suppose it does have the potential for optimistic interpretations though.
