How to detect a map service status

Mr_Kirkwood

I have several outside services that i use in my map. Sometimes these services may be down and it affects the loading of my map. I would like to check on the status of the services and if they are down the application would not put them in the map and TOC. I am using the ESRI JavaScript API. Thanks!

I got this to work for me thanks. I also had to modify the TOC code as follows:

//Code for the  layers in the TOC

        var myLayers = map.getLayer("myLayers ");

        if (myLayers !== undefined) {

            myLayers .setVisibility(false);

            myLayers .setOpacity(0.7);      

            tocEORI = new TOC({

                map: map,

                layerInfos: [{

                        layer: myLayers ,

                        title: "Enhanced Oil Recovery Institute",

                        collapsed: true,

                        slider: false

                    }

                ]

            }, 'tocmyLayers Div');

            tocmyLayers .startup();

        }

        else {

            alert("The service is not available. Please refresh at a later time. This will not affect the overall functionality of the map.");

        }
