https://community.esri.com/t5/open-source-mapping-libraries-ques/map-feature-service-loading-error-handling/m-p/855586#M216 <P>I've been working on a solution to deal with map/feature services not loading on a map.&nbsp; Sometimes ArcGIS for Server has hiccups.&nbsp; I also wanted to have a loading screen disappear after the layers load.&nbsp; I have a <A href="https://codepen.io/pmckinney/pen/XVJezp" target="_blank">CodePen</A> demo with my solution. I'm looking for feedback (positive and negative).</P> <P>&nbsp;</P> <P>I added a property, <STRONG>isLoaded</STRONG>, that stores a boolean for whether they layer has been loaded or not.&nbsp; It is initially false, and during the "<STRONG>load</STRONG>" event, is changed to true.&nbsp; It is set to false during the "<STRONG>requesterror</STRONG>" event.</P> <P>&nbsp;</P> <P>I then have an interval timer that checks whether the <STRONG>isLoaded</STRONG> property for all layers is true. If it is, then the loading screen is removed.</P> <P>&nbsp;</P> <P>During the "<STRONG>requesterror</STRONG>" event, I add some html to a hidden element (modal) that stores an error message.&nbsp; This element is then displayed. Upon closing the modal, the loading screen is removed.</P> Mon, 28 Aug 2023 13:00:27 GMT PatrickMcKinney1 2023-08-28T13:00:27Z https://community.esri.com/t5/open-source-mapping-libraries-ques/map-feature-service-loading-error-handling/m-p/855586#M216 <P>I've been working on a solution to deal with map/feature services not loading on a map.&nbsp; Sometimes ArcGIS for Server has hiccups.&nbsp; I also wanted to have a loading screen disappear after the layers load.&nbsp; I have a <A href="https://codepen.io/pmckinney/pen/XVJezp" target="_blank">CodePen</A> demo with my solution.
