Attempting to retrieve exclusively the checked records in Vue.js

Question

Attempting to retrieve exclusively the checked records in Vue.js

Currently, I am referring to this library for checkboxes. As I delve into the code, I notice how it is declared and utilized.

Initially within the el-table, we have

@selection-change="handleSelectionChange"

. They have initialized an empty array element in the data section like so:

data() {
  retrun {
    multipleSelection: []
  }
}, 
methods:{
  handleSelectionChange(val) {
    this.multipleSelection = val;
  }
}

I am currently trying to filter out only the records of clicked checkboxes. My method looks something like this -

let data = [];
console.log(this.multipleSelection.length);
if (this.multipleSelection.length == 0) {
    data = JSON.parse(JSON.stringify(this.myapidata));
} else {
    data = JSON.parse(JSON.stringify(this.multipleSelection));
}

However, despite my efforts, I am still retrieving all the data instead of just the selected ones. If anyone has encountered a similar issue and can provide guidance, please assist.

Answer №1

By checking the checkboxes, the v-model variable automatically updates itself with the chosen values, showcasing the functionality of two-way binding. To view the selected items, log the multipleSelection within your method:

methods: {
  handleSelectionChange() {
    // This will only display the selected items
    console.log(this.multipleSelection);
  }
}

You will notice that only the chosen items are visible in the multipleSelection array.
