Tips for modifying a particular element within a class?

Question

Tips for modifying a particular element within a class?

I am seeking guidance on how to modify a specific class attribute in CSS/JS/JQuery when hovering over a different element. Here is an example:

<h1 class="result">Lorium</h1>
<h1 class="result">Ipsum</h1>
<h1 class="result">Dolor</h1>
<img src="example.png" class="images"/>
<img src="example.png" class="images"/>
<img src="example.png" class="images"/>

My goal is for the src of the <img> tag to change when I hover over one of the <h1> tags, while keeping the rest unchanged. Should I accomplish this using CSS, JS, or JQuery? How should I proceed?

Please note that I need to use classes instead of IDs because I will be styling these elements dynamically with PHP.

Thank you,

Answer №1

To start, the hover or mouseenter event needs to be detected on the H1 element with the class result.

Assuming all your results have the class result, you can proceed.

$('.result:eq(0)').mouseenter(function(){
console.log("hello world");
});

Then, you should update the img src linked to the result - assuming all images share the same class.

$('.result:eq(0)').mouseenter(function(){
    $('.images:eq(0)').attr('src','https://via.placeholder.com/150x150')
});

It's recommended to create a function to avoid hardcoding the nth value of the class selector.

For more information: https://api.jquery.com/eq-selector/

If jQuery is not being used, similar logic can be applied using document.querySelector('.result')[0] etc.

For further details:

EDIT -- For nth value where n represents the same index number for both result and images

$('.result').mouseenter(function(){
    var nValue = $(this).index();
    $('.images:eq('+nValue+')').attr('src','https://via.placeholder.com/150x150')
});

Firstly, it appears that the structure of your HTML may not be very adaptable. Relying on the order of elements might not be a good approach. It would be better to reorganize the HTML code as shown below:

<div class="result-container">
  <h1 class="result">Result title</h1>
  <img src="something.png" class="image" />
</div>

To handle events with jQuery, you can use the following script:

function onHoverIn() {
  const resultTitle = $(this);
  const image = $(this).parent().find('.image')[0];

  image.attr('src', 'something-hovered.png');
}

function onHoverOut() {
  // same logic
}

$('.result-container .result').hover(onHoverIn, onHoverOut);

I hope this information proves useful!

When using jQuery, you can update an image by targeting its class like this:

$(".images").attr("src","second.jpg");

However, if all the images share the same class, this may not give you the desired result. In order to distinguish between images and associate them with header tags, you will need a way to differentiate them from each other.

If you have multiple images and want to manipulate each one individually, you might consider something along these lines:

$('.images').each(function() {
    //Evaluate each image separately
});
