Question

Exploring the functionality of Jquery with the :active selector

Here is the code I have been working on:

$('#ss a:active').parent().addClass('ss-active');

It seems like my code is not functioning as expected. Can you help me figure out how to achieve my desired outcome? Additionally, I want the button to return to its normal state when the user moves the mouse away from it. By "removing the mouse from the button," I mean that the user should only click and hold on the button briefly to trigger the :active state.

I am unable to accomplish this using CSS alone because I require access to the parent element of the <a> tag.

//After troubleshooting, I managed to make it work with the following solution:

    $('#solicita a').mousedown(function() {
    if($(this).parent().hasClass('solicita-hover'))
    {
        $(this).parent().removeClass('solicita-hover');
        $(this).parent().addClass('solicita-active');
    }
}).mouseleave(function() {
    $(this).parent().removeClass('solicita-active');
});

A detailed explanation for beginners learning about jQuery

It's important to understand the sequence of events in Javascript. When your script is read by the browser, it processes it line by line, top to bottom.

When jQuery reads your CSS selectors (such as those from Sizzle), it looks at the current state of the document to find the specified elements. For example, if you use

$('#my-id div').addClass( 'some-class' )

, jQuery will add classes to the divs within the element with an id of my-id at that exact moment.

If you later add more divs to #my-id, they won't automatically get the added classes because they weren't present when the script was initially processed.

Therefore, when someone writes

$('#ss a:active').parent().addClass('ss-active');

, the browser only looks for #ss a:active at the specific time that line is executed.

To detect potential future events, we need to bind Javascript events accordingly

This is why we use something like

$('#ss a').mousedown( function ).mouseup( function )

. By doing this, we inform jQuery and the browser that we are actively waiting or listening for a particular event to occur.

Within the realm of jQuery, the ":" functions as a meta-character. Typically, what comes after the ":" is considered jQuery selector syntax, such as ":file" or ":has()".

It's worth noting that ":active" is a CSS pseudo-class, and this use of ":" to indicate pseudo-classes may clash with the requirements of jQuery selector syntax.

With all of this in mind, one possible solution could be to attempt escaping the ":" by using two backslashes, as suggested in the jQuery api documentation. However, I have not personally tested this approach.

In certain modern browsers like Firefox, Chrome, and IE10+, you have the ability to listen for matches of selector rules by creating a dummy CSS Keyframe and capturing the animationstart event when it corresponds to the selector you're interested in.
