When utilizing Vue and arrow functions in methods, we encounter the issue that arrow functions do not have a this keyword. The question then arises of how to access data properties such as list or object.
export default {
data() {
return {
list: [],
object: {},
}
},
methods: {
onSubmit: (e) => {
//How can access this here?
//Im trying to access this.list
console.log(this);
}
},
}
Your help is much appreciated.
Avoid using arrow functions for declaring methods in Vue components as it is not recommended.
Instead, consider using a method declaration like this:
methods:{
onSubmit(e){
...
}
}
