Executing Cascading Style Sheets (CSS) within JQuery/Javascript

I've been encountering a problem with my website. I have implemented grayscale filters on four different images using CSS by creating an .svg file. Now, I'm looking to disable the grayscale filter and show the original colors whenever a user clicks on an image. The challenge is that CSS only has :active and :hover options, but I want this effect during click action. Below is the code I've used:

//CSS
<style type="text/css">
 #main, #beverage, #set, #appetizer {
filter: url(filters.svg#grayscale); /* Firefox 3.5+ */
filter: gray; /* IE6-9 */
-webkit-filter: grayscale(1); /* Google Chrome & Safari 6+ */
}
#main {
filter: none;
-webkit-filter: grayscale(0);
}

//IMAGES
<td>
<img src="main.png" width="80" style="cursor:pointer" id="main"><br>
<img src="beverage.png" width="80" style="cursor:pointer" id="beverage"><br>
<img src="set.png" width="80" style="cursor:pointer" id="set"><br>
<img src="set.png" width="80" style="cursor:pointer" id="appetizer"><br>
</td>

Answer №1

If you want to create a cool grayscale effect for your images that can be removed when clicked, all you need to do is set up a class with the grayscale filter and then toggle it off upon clicking.

HTML

<img src="main.png" width="80" style="cursor:pointer" id="main" class="grayscale"><br>
<img src="beverage.png" width="80" style="cursor:pointer" id="beverage" class="grayscale"><br>
<img src="set.png" width="80" style="cursor:pointer" id="set" class="grayscale"><br>
<img src="set.png" width="80" style="cursor:pointer" id="appetizer" class="grayscale"><br>

CSS

.grayscale {
    filter: url(filters.svg#grayscale); /* Firefox 3.5+ */
    filter: gray; /* IE6-9 */
    -webkit-filter: grayscale(1); /* Google Chrome & Safari 6+ */
}

jQuery

$('.grayscale').click(function(){
    $(this).removeClass('grayscale');
});

Answer №2

Update the CSS property 'key' with a new value for element with ID 'id'.

Answer №3

Modify the CSS properties within the click event:

$("#front, #back, #top, #bottom").click(function() {
    $(this).css({ filter: "none",
                  "-webkit-filter": "grayscale(0)"
                });
}

Answer №4

$('img.#main, img#beverage, img#set, img#appetizer').click(function(){
    $(this).css({
        '-webkit-filter': '',
        'filter': ''
    })
});

Answer №5

For the most flawless functionality and to avoid any potential issues down the line, it's important to also include z-index in this class:

.grayscale {
    filter: url(filters.svg#grayscale); /* Firefox 3.5+ */
    filter: gray; /* IE6-9 */
    -webkit-filter: grayscale(1); /* Google Chrome & Safari 6+ */
    z-index:100;
}
Then, implement a click function as follows:

$('.grayscale').click(function(){
    $(this).removeClass('grayscale');
});
