Locating and substituting HTML elements with jQuery

I have a very specific issue that I need help with. On my website, users can select the number of results they want to see displayed. I created buttons and a span element to show the currently selected amount. Now, I am trying to implement an ajax request for this functionality. I need to figure out how to determine the current selected amount and update the HTML so that it always displays the correct amount. My main question is: How can I identify the current data ID and replace only that specific HTML line when a button is clicked?

This is my current HTML setup:

<div class="pagination">
    <span>Show orders</span>
    <a href="" data-id="25">25</a>
    <span class="active" data-id="50">50</span>
    <a href="" data-id="75">75</a>
    <a href="" data-id="100">100</a>
    <a href="" data-id="125">125</a>
    <a href="" data-id="150">150</a>
    <a href="" data-id="1000">All</a>
</div>

My JQuery code to retrieve the current selected amount:

var selectedAmount = $( ".pagination" ).find ( ".active" ).data( "id" );

And here is my JQuery event handler to swap out the buttons with the span element upon click:

$('.pagination a').on('click', function(event){
    event.preventDefault();
    // Replace the old highlighted amount button with an <a href> tag
    // Swap the old <a href> tag with the newly "highlighted" span button
});

Answer №1

The retrieval of selectedAmount appears to be efficient. Consider optimizing it for simpler code:

var selectedAmount = $( ".pagination .active" ).data( "id" );

Regarding the latter part of your code:

$('.pagination').on('click', 'a', function(event){
    event.preventDefault();

    // Swap out the old highlighted amount button with an <a href> tag

    $('.pagination .active').replaceWith(
      function() {
        var el = $(this);
        var id = el.data('id');
        var txt = el.text();

        var a = $('<a>').text(txt).data('id', id).attr('href', '#');
        return a;
      }
    );

    // Replace the old <a href> tag with the new "highlighted" span button
    var id = $(this).data('id');
    var txt = $(this).text();
    var sp = $('<span class="active"></span>').text(txt).data('id', id);
    $(this).replaceWith(sp);

});

To achieve this, you might consider using a method like replaceWith:

$("button").replaceWith( "<a href='#'>Link</a>" );

Without specific details on what needs to be replaced, the provided code snippet serves as an illustrative example. If you could share more information or a demo in a fiddle, I would be able to offer more tailored assistance.
