The functionality of "#button_1" remains unchanged despite using .click() or .hover() methods

Question

The functionality of "#button_1" remains unchanged despite using .click() or .hover() methods

Seems like I made a beginner's error - the #button_1 ID seems to be immune to the jQuery effects of click() or hover().

If someone could spare a moment to check out my JSFiddle, it would be incredibly helpful.

It's likely something quite simple, but I just want #button_1 to behave like any other button. :)

Once more, I have a feeling it's a small oversight on my part.

Answer №1

Avoid repeating code too much, give this a try and see if it works

Go through the code line by line, there seems to be an error causing issues with the bind events. There might be an issue with the hover function, try removing everything except for the bind events.

It's important to remember that if line 1 breaks in the document ready function, any bindings below it may not be successful.

$(document).ready( function () {
 
   $('#button_1,#button_2').click(function() {
  alert('Handler for .click() called.');

   });

});

Perhaps you could consider streamlining the code to something like this:

$('a div[class^="button"]').click(
    function(e){
        e.stopPropagation(); 
        $('.button_active')
            .removeClass('button_active')
            .addClass('button_normal');
        $(this).addClass('button_active').removeClass('button_normal');
    });

Here's a JS Fiddle demo.

Update based on the question from the original poster:

I noticed that after implementing [the updated code in the Fiddle], it uses "button_hover" instead of "button_active". Any idea why?

That behavior is due to how CSS specificity works - I manage classes dynamically to respond to events, avoiding repetitive checks for specific class states. This results in having both classes present like

class="button_normal button_hover"

, with priority given to the later-declared class which maintains "button_hover". It may seem complex, but essentially achieves the desired functionality.

The below code incorporates all necessary modifications and updates to meet your requirements:

$('a div[class^="button"]').hover(
    function(){
        $(this).addClass('button_hover').click(
            function(e){
                e.preventDefault();
                $('.button_active')
                    .addClass('button_normal')
                    .removeClass('button_active');
                $(this).addClass('button_active').removeClass('button_hover');
            });
    },
    function(){
        $(this).removeClass('button_hover');
    });

CSS:

.button_active,
.button_normal.button_active { background: #000; }
.button_normal.button_hover { background: #ff0; }
.button_normal { background: #d89; }
