Store locator w/ google maps in classic ASP
I can't find anything on how to create a store locator with google maps using classic ASP (n开发者_运维百科ot .net). Can anyone help me out with this? I have looked everywhere.
Very little of this would have anything with your server side code to do.
If you took the AJAX-aproach (apropriate since you're using gmaps), your backend code would need to provide a list of stores with lat/lng location and perhaps states for further filtering.
This could be as simple as returning javascript (JSONP) with the data wrapped in a callback function:
[YourJSONPDataScript.asp]
<%
Response.Write "updateMyMapData(["
Do While Not Rs.Eof
Response.Write "{ lat: " & Rs("Lat") & ", lng: " & Rs("Lng") & " }"
Rs.MoveNext
If Not Rs.Eof Response.Write ", "
Loop
Response.Write "]);"
%>
The main benefit begin the ability to port this to any other plattform by just changing the code that generates your JSONP-data :-)
And finally your HTML-page would contain a script block:
<script type="text/javascript">
function updateMyMapData(stores) {
for (var i=0; i < stores.length; i++) {
var store = stores[i];
// do stuff with store.lat, store.lng, add markers to map and populate select boxes.
}
}
</script>
<script type="text/javascript" src="/YourJSONPDataScript.asp">
</script>
