JavaScript events raised by the map

All the maps in FusionMaps v3 suite can raise the following events. Please note that the events are raised only when registerWithJS flag of the map is set to 1.

Event Name When is it raised? What to use it for?
FC_Loaded(DOMId) When the map SWF has finished downloading in the user's browser. To hide any loader components that you might have on your page.
FC_Rendered(DOMId) When the map has finished rendering. This call is made only once per loaded map SWF (even if new data is supplied to it via setDataURL or setDataXML method). To invoke any further JavaScript methods on map, or to change the data of map.
FC_DataLoaded(DOMId) When the data of the map has finished loading - both in dataXML or dataURL method. To further process data in any other components in your page.
FC_DataLoadError(DOMId) When there was an error in loading data from the specified URL To show an error message to user, or to take a corrective measure
FC_DataXMLInvalid(DOMId) When the XML data loaded by map was invalid (wrong XML structure) To show an error message to user, or to take a corrective measure
 
How to track these events?
The events raised by FusionMaps are simple JavaScript functions that are invoked, and the DOMId of the invoking map is passed to the function to help you identify the source. For example, the FC_Rendered event for a map can be tracked using following code:
<HTML>
<HEAD>
    <TITLE>FusionMaps & JavaScript - Basic Example</TITLE>
    <SCRIPT LANGUAGE="Javascript" SRC="../JSClass/FusionMaps.js"></SCRIPT>
    <SCRIPT LANGUAGE="JavaScript">
        //FC_Rendered method is called whenever a FusionMaps map on the page
        //has finished initial rendering. To this function, the map passes its
        //own DOM Id.
        function FC_Rendered(DOMId){
            //If it's our required map
            if (DOMId=="map1Id"){
                //Simply alert
                window.alert("Look Ma! I am World Map and I've finished loading and rendering.");
                return;
            }
        }
    </SCRIPT>
</HEAD>
<BODY>
    <div id="map1div">
        FusionMaps
    </div>
    <script language="JavaScript">
        var map1 = new FusionMaps("../Maps/FCMap_World.swf", "map1Id", "750", "400", "0", "1");
        map1.setDataXML("<map borderColor='005879' fillColor='D7F4FF' numberSuffix=' Mill.' includeValueInLabels='1' labelSepChar=': ' baseFontSize='9'><data> <entity id='NA' value='515' /><entity id='SA' value='373' /><entity id='AS' value='3875' /><entity id='EU' value='727' /><entity id='AF' value='885' /><entity id='AU' value='32' /></data></map>");
map1.render("map1div");
