Hello… new user here
I need to write a piece of JS code that will do the following..? any help in the direction I need to go would be greatly appreciated!
I setup a Google Api map that returns a company name/coordinates XML string that gets loaded into my map and plotted.
I have a clickable list of companies on the right hand side of the map with state abbreviations pulled from the XML… my question is how do I put the state name at the top of the company list and everytime the state changes in the list it changes the state name
like this:
[U][B]Arizona:
Company A, AZ
Company B, AZ
Company C, AZ
[U][B]Kansas:
Company B, KS
[CODE]<cfxml variable=”xmlObject” casesensitive=”yes”>
<markers>
<cfoutput query=”mapquery”>
<marker lat=”#XmlFormat(lat)#” lng=”#XmlFormat(lng)#” html=”<b><center>#XmlFormat(companyname)#</b><br>#XmlFormat(address)#, <br> #XmlFormat(city)#, #XmlFormat(state)# #XmlFormat(postalcode)# <br> #XmlFormat(phone)#</center>” label=”#XmlFormat(companyname)#”></marker>
</cfoutput>
</markers>
</cfxml>
<cffile action=”WRITE”
file=”#ExpandPath(‘data.xml’)#”
output=”#ToString(xmlObject)#”>
<script type=”text/javascript”>
//<![CDATA[
if (GBrowserIsCompatible()) {
// this variable will collect the html which will eventually be placed in the side_bar
var side_bar_html = “”;
// arrays to hold copies of the markers and html used by the side_bar
// because the function closure trick doesnt work there
var gmarkers = [];
var htmls = [];
var i = 0;
// A function to create the marker and set up the event window
function createMarker(point,name,html) {
var marker = new GMarker(point);
GEvent.addListener(marker, “click”, function() {
marker.openInfoWindowHtml(html);
});
// save the info we need to use later for the side_bar
gmarkers[i] = marker;
htmls[i] = html;
// add a line to the side_bar html
side_bar_html +='<a href=”javascript:myclick(‘ + i + ‘)”>’ + name + ‘</a><br>’;
i++;
return marker;
}
// This function picks up the click and opens the corresponding info window
function myclick(i) {
gmarkers[i].openInfoWindowHtml(htmls[i]);
}
// create the map
var map = new GMap2(document.getElementById(“map”));
map.addControl(new GLargeMapControl());
map.addControl(new GMapTypeControl());
map.setCenter(new GLatLng(38.9, -93.8), 4);
// Read the data from data.xml
var request = GXmlHttp.create();
request.open(“GET”, “data.xml”, true);
request.onreadystatechange = function() {
if (request.readyState == 4) {
var xmlDoc = request.responseXML;
// obtain the array of markers and loop through it
var markers = xmlDoc.documentElement.getElementsByTagName(“marker”);
for (var i = 0; i < markers.length; i++) {
// obtain the attribues of each marker
var lat = parseFloat(markers[i].getAttribute(“lat”));
var lng = parseFloat(markers[i].getAttribute(“lng”));
var point = new GLatLng(lat,lng);
var html = markers[i].getAttribute(“html”);
var label = markers[i].getAttribute(“label”);
// create the marker
var marker = createMarker(point,label,html);
map.addOverlay(marker);
}
// put the assembled side_bar_html contents into the side_bar div
document.getElementById(“side_bar”).innerHTML = side_bar_html;
overflow: auto;
}
}
request.send(null);
}
else {
alert(“Sorry, the Google Maps API is not compatible with this browser”);
}
</script>
Thanks in advance for any help!!
