How to unbind an array copy in Vue.js?
In Vue.js, you can bind an array to a data property using the v-model directive. By default, Vue.js binds the array by reference, which means that changes to the original array will be reflected in the copy.
However, if you want to unbind the array copy so that changes to the original array do not affect the copy, you can use the Array.slice() method to create a new copy of the array.
Here is an example of how to unbind an array copy in Vue.js:
Original Array
- {{ item.name }}
Array Copy
- {{ item.name }}
In the above example, we create a new copy of the originalArray by calling the Array.slice() method in the mounted() hook. This creates a new copy of the array that is not bound by reference to the original array.
Note that if you want to modify the copy of the array without affecting the original array, you should modify the copy directly and not modify the original array.
