问题 Let's say I have CountrySelect and CitySelect , where in CountrySelect are listed all countries and in CitySelect are only listed those cities of currently selected country... What would the proper way to pass newly selected country. As I have read in vuejs documentation: In Vue, the parent-child component relationship can be summarized as props down, events up. The parent passes data down to the child via props, and the child sends messages to the parent via events. Let’s see how they work

问题 I am trying to push data from a v-text-field onto a json file. When i tried it on Postman it worked so I'm guessing the error is coming from the client side product.vue <v-container> <v-row> <v-col> <v-text-field label="440" v-model="onetext" ></v-text-field> <v-text-field label="Card Type" v-model="twotext" ></v-text-field> <v-text-field label="Card Type" v-model="threetext" ></v-text-field> <v-text-field label="Card Type" v-model="fourtext" ></v-text-field> <v-text-field label="Card Type" v

问题 I would like to create a Vuetify table with nested data. The problem is that v-slot:item doesn't seem to work with nested data.

问题 I am using Github's API to fetch the list of my pinned repositories, and I put the call in the AsyncData method so that I have the list on the first render. But I just learnt that AsyncData is called once on ServerSide, then everytime the page is loaded on the client.

I use leafletPip.pointInLayer(point, layer) from https://github.com/mapbox/leaflet-pip for determining which polygons do overlap. This happens in the processClick function. In the Vue object I create the map and my GeoJSON layer with the polygons. What I now want is following feature: if you click on a point on the map and this point is contained in multiple polygons, you have something like a selection tool, e.g.
