Can Vue.js detect the swapping of array elements in my data object?
data: {
list: [
'Foo',
'Bar',
'Test'
]
}
This is the method I am using to swap entries:
swapIndex: function(from, to) {
var first = this.list[from];
this.list[from] = this.list[to];
this.list[to] = first;
}
Check out the JsFiddle at this link.
If I swap the indices, I want to re-render the v-for loop. Any suggestions on how to achieve this?
Appreciate any help. Thank you!
Here is my unique solution that I have come up with. In order to modify the list, I decided to create a duplicate of the original list and then used the this.$set() method to make the necessary changes:
new Vue({
el: '#app',
data: {
items: [
'Apple',
'Banana',
'Orange'
]
},
methods: {
switchItems: function(fromIndex, toIndex) {
var duplicate = JSON.parse(JSON.stringify(this.items));
var firstItem = duplicate[fromIndex];
duplicate[fromIndex] = duplicate[toIndex];
duplicate[toIndex] = firstItem;
this.$set(this, 'items', duplicate);
console.log(this.items);
}
}
})
