Creating a button to display the following 5 arrays after using the slice method

Question

Creating a button to display the following 5 arrays after using the slice method

Is it possible to create a button in my code that will display the next 5 arrays from a table with over 15 arrays, after slicing it to show only 5 of them initially?

Here is the code snippet I am working with:

          <tbody>
            <TableRow
              v-for="mandate in filteredMandates.slice(0, 5)"
              :mandate="mandate"
              :theme="getColor(mandate.asset_classification)"
              :key="mandate.isin"
            />
          </tbody>

I attempted to implement a button functionality to display the next 5 sliced items but struggled due to my limited knowledge in JavaScript. Unfortunately, my effort resulted in an error.

Answer №1

If you want to optimize your Vue script, consider setting two data attributes within the function.

data(){
 pageIndex: 0,
 pageSize: 5
}

With this setup, your code can be structured like this:

<tbody>
  <TableRow
    v-for="mandate in filteredMandates.slice(pageIndex, pageSize)"
    :mandate="mandate"
    :theme="getColor(mandate.asset_classification)"
    :key="mandate.isin"
  />
</tbody>

Your next page button should increment the page index by the page size:this.pageIndex += this.pageSize

To enhance performance and avoid repeated array slicing, you can modify your code as follows:

<tbody>
  <TableRow
    v-for="i in pageSize"
    :mandate="filteredMandates[startIndex+i-1]"
    :theme="getColor(filteredMandates[startIndex+i-1].asset_classification)"
    :key="filteredMandates[startIndex+i-1].isin"
  />
</tbody>

And similarly, your next page button would adjust the page index accordingly this.pageIndex += this.pageSize

This approach ensures that the original array is preserved without duplication, simply by updating the view start index for each new page.
