Exploring the concept of front-end deletion through ajax technology

I'm currently tackling a front-end CRUD RESTful API project and encountering challenges specifically related to the DELETE and PUT methods.

While I have successfully managed to implement the GET and POST functionalities, utilizing a forms.html file for posting data and ensuring that my Ajax calls to localhost:3000/submit/ (the location of my form.html page) properly handle invalid formatting.

The issue lies in incorporating a Delete button within a dynamic table on the front end (each row contains one such button created using JavaScript). I am uncertain how to instruct the system to "delete this row" upon clicking. On the backend, I have an app.delete route which follows the format: localhost:3000/pokemon/del/7, where triggering this URL would delete the entry corresponding to the 7th position, for instance. The same logic applies to other entries as well. Are there any recommended documentation or suggestions you can provide to assist me with this task?

My current strategy involves creating a JavaScript loop that iterates through each button, assigning it an ID attribute ("delButton" + j) based on the iteration variable 'j'. This results in having multiple delete buttons labeled as delButton1, delButton2, delButton3, and so forth. Upon click, I plan to execute an Ajax delete request with the endpoint "http://localhost:3000/pokemon/del/" appended with the specific ID number from the button. While this approach seems promising, I remain open to alternative suggestions or solutions to enhance its effectiveness.

There are countless approaches to tackling this issue, and it's possible that this question may be flagged by Stack Overflow due to their preference for clear-cut solutions. However, I'll provide a starting point for you.

Your current method is on the right track. One improvement could be assigning row numbers as they are generated, using a unique identifier like data-row-id to avoid conflicts with actual IDs. Having an ID of 1 on an entire page could lead to issues in the future.

To streamline the deletion process, consider adding a delete button to each row. This button can extract the parent's data-row-id to execute a DELETE request, removing the row upon successful completion.

If you're diving deeper into this concept, exploring frameworks like Vue or React might be beneficial. These tools link the view and data, creating a dynamic relationship where modifications to the data automatically reflect in the view - ensuring seamless updates within the table.

Is my understanding correct that after performing an Ajax call, all you need to do is delete the corresponding row in your table?

If that's the case, you can simply pass the button DOM element reference to your onClick function.

Check out this jsFiddle for a working example.


function deleteRow(el) {
    // Perform an Ajax call
    $.post('/delete', function() {
        $(el).parents('tr').remove();
    }).always(function() {
        $(el).parents('tr').remove();
    });
}
