modify the b-form-checkbox component in a Vue application

Question

modify the b-form-checkbox component in a Vue application

I have inserted the <b-form-checkbox> element into a <b-table>:

https://jsfiddle.net/fmattioni/L269rd7s/

This is my current objective:

1 - Initially, all checkboxes in the table are checked using checked="true".

2 - Try unchecking any checkbox as an example.

3 - Change the date on the calendar now.

4 - The issue arises here: after changing the date, I want all checkboxes to revert to their initial states, with all of them being checked.

I am looking to accomplish this through one of the following methods:

Option #1 - Is it possible to define within my data items whether a column should be checked or not? I attempted the following:


items: [
        {id: 1, check: true,},
        {id: 2, check: true,},
        {id: 3, check: true,},
      ]

However, I haven't figured out how to instruct <b-form-checkbox> to do so. For instance, I would like to set id: 2 initially as check: false, and the others as check: true. Is this achievable?

Option #2 - It would suffice if I could simply reset all values to true once the date changes.

Any suggestions or solutions for this scenario?

Modify the #cell(check)="row" to

#cell(check)="{ item }"

<div id="app">
  <div>
    <b-form-datepicker
    value='2021-04-25'
    >
    </b-form-datepicker>
    <b-table
    :items='items'
    >
      <template #cell(check)="{ item }">
        <b-form-checkbox
        v-model="item.check"                 
        >
        </b-form-checkbox>
      </template>
    </b-table>
  </div>
</div>

This adjustment allows the component to receive the item from the table component. Your #cell slot contains additional data like index, which may be necessary for other uses.

I believe that using watch may be unnecessary as it can add overhead to your code. Instead, you can utilize @input to detect changes and then call the reset method. I have included a code snippet below for better clarity.

new Vue({
  el: "#app",
  data() {
    return {
      date: new Date(),
      items: [{
          id: 1,
          check: true,
        },
        {
          id: 2,
          check: false,
        },
        {
          id: 3,
          check: true,
        },
      ]
    }
  },
  methods: {
    reset_checkboxes() {
      this.items.forEach((el) => {
        el.check = true
      })
    }
  }
});
