Below is the code snippet:
<ul>
<li v-for="value in RandomTopic" :key="value.id">{{ value.title }}</li>
</ul>
export default {
data() {
return {
RandomTopic: null
}
},
mounted() {
///some method to fetch data from remote server
console.log(res.data);
this.RandomTopic = res.data;
}
}
The objective is to display all the data obtained from the remote server on the front end. However, upon execution, an error is reported:
Cannot set property 'RandomTopic' of undefined ; at api request success callback function
TypeError: Cannot set property 'RandomTopic' of undefined
Even though console.log(res.data); successfully logs the JSON, it doesn't appear to be related to AJAX or the remote server.
Additionally, presented here is a sample of the JSON structure:
[
{
"id": 421,
"title": "sample1",
"image_url": "bus.png"
},
{
"id": 535,
"title": "sample78",
"image_url": "car.png"
}
]
I would appreciate any assistance as I am relatively new to Vue 3. Thank you!
