In a Vue serverless web application, OpenLayers Map object fails to trigger events

In my Vue serverless web application, I have implemented an OpenLayers map initialized in the mounted lifecycle method. The map is populated with ImageWMS layers that are updated by various functions. After updating the parameters of these layers, I call this.map.renderSync() and attempt to execute another function only when all layers have finished loading and rendering (as indicated by the rendercomplete event). However, I noticed that the callback

this.map.on("rendercomplete",this.myFunction())
triggers only once, during the initial rendering in the mounted method. How can I ensure that this.myFunction() is executed only after all layers have been loaded and rendered following parameter updates?

async mounted() {
    // Map initialization code
},
methods: {
    // Other methods including setTimeSurface10, flagCallback, mapToCanvasList, myCallback
}

Answer №1

this.map.on requires 2 parameters: the event name as a string ("rendercomplete") and a callback function. The provided callback function is this.flagCallback but make sure not to include the (). The console will only log once since the function is called once when the listener is set up.
