How do I refresh static map?

AlexanderCrawford

I would like to refresh ArcGIS map on the page when my ajax completes call. I have a function that gets executed when ajax completes call in that function i have:

function onAjaxSuccess()
{

map.setExtent(map.extent);
mapLayer.refresh();

}

but map does not get refreshed.

I figured it out!

These are the methods that need to be called in ajax onSuccess function

map.destroy();
dojo.addOnLoad(init);

and arcgis reloads the map.

Alex: I think I might be confused as to what you are trying to accomplish.

Can you recreate a sample of your issue using jsfiddle.net?

No, I cannot provide this sample, it's an MVC web app and there are many parts that make one page.

But I'll try to explain it better does arcgis map has similar function like for example jquery chosen $('#dropdownlist').trigger("chosen:updated");

Maybe this will make it more clear;

I have a page and on that page I have a drop down box with "Location 1", "Location 2", "Location 3". On that same page I have an html element <div id="map"></div>. When page loads the first time map arcgis automatically inserts the map in to <div id="map"></div> for "Location 1".

In situation when someone chooses "Location 2" from drop down javascript ajax removes <div id="map"></div> and reinserts it. When it reinserts it <div id="map"></div> has no map in it. My question is, how do I tell arcgis to reinsert map into <div id="map"></div> again and with "Location 2"?

One other thing that might help is that I have a html tag <div id="map"></div> when page loads arcgis inserts map into that tag, when ajx call completes it reloads <div id="map"></div> tag. I guess better question would be how do I ask arcgis to reinsert map in to <div id="map"></div> tag?

Try console.dir(map) before your setextent. I bet you your map object is null do to a scoping issue

Map object is not null.

If you are just changing the extent, no refresh is needed.

Make sure you have a direct reference to the map object in your callback.

If this doesn't fix the issue, could you create a sample using jsfiddle.net so I can take a look? Thanks!

Here is the initialization code for the map:

function init() {

    map = new esri.Map("map", { slider: false, logo: false });
    dojo.connect(map, "onLoad", function () {
        map.disableClickRecenter();
        map.disableDoubleClickZoom();
        map.disableKeyboardNavigation();
        map.disableMapNavigation();
        map.disablePan();
        map.disableRubberBandZoom();
        map.disableScrollWheelZoom();
        map.disableShiftDoubleClickZoom();
        map.hidePanArrows();
        map.hideZoomSlider();
    });

    dojo.connect(map, "onExtentChange", showScaleInfo);    
    //instantiate the PCI map service
    swaMapLayer = new esri.layers.ArcGISDynamicMapServiceLayer(PCILayer, { "visible": true });
    //add the PCI layer to the map
    map.addLayer(swaMapLayer);
    //scalebar = new dtdg.scalebar(map);

    //get the SourceTagNumber
    featureId = $('#SelectASourceSelected').val();
    var queryTask, query;
    //build a query to get the extent of the SWA delineated area
    queryTask = new esri.tasks.QueryTask(queryLayer);
    query = new esri.tasks.Query();
    //the geometry is needed to get the extent of the feature
    query.returnGeometry = true;

    query.where = "SRCID='" + featureId + "'";    

    queryTask.execute(query, onQueryResult);
}

I show map on the website based on "featureId" value. featureId is value of the drop down box.

When my ajax completes function:

function ajaxOnSuccess() {

}

gets called, how in that function do i tell arcgis to reload its static map?

Hey Alex! The map shouldn't need to be refreshed in normal circumstances.

What is your use-case and could you provide a sample using jsfiddle.net?

Thanks!

I have a drop down and ajax handler that is attached to that drop down. When selection in the drop down changes I would like to show new map based on what's selected in that drop down box without refreshing whole page.
