I have a block where the main picture changes when clicked
$('.img-to-select__item').click(function () {
$('.img-to-select__item').removeClass('selected');
$(this).addClass('selected');
$('.main-image > img').attr('src', $(this).children('img').attr('src'));
$('.custom-carousel__title > span').html($(this).children('img').attr('data-title'));
});.custom-carousel {
text-align: center;
}
.main-image > img {
width:50px;
}
.img-to-select > .img-to-select__item > img {
heigh:30px;
width: 30px;
}
.img-to-select {
overflow: hidden;
display: flex;
justify-content:space-around;
}
.img-to-select > .img-to-select__item {
display: flex;
justify-content:space-around;
}
.img-to-select > .img-to-select__item.selected {
border: 2px solid red;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>Now everything works so when you click on img-to-select it becomes main-image. But can it be done a little differently?
Let's say there are two fields main_image and preview_image, they will be exactly the same, the only size is different
Suppose we have one main-test.jpg picture, it is in the main-image class, and exactly the same picture, only with a smaller size preview-test.jpg in class img-to-select
And there are several such pictures
main-test-1.jpg and preview-test-1.jpg
main-test-2.jpg and preview-test-2.jpg
main-test-3.jpg and preview-test-3.jpg
main-test-4.jpg and preview-test-4.jpg
The code will now look like this
<div class="main-image">
<img src="main-test-1.jpg" alt="" data-title="image-a">
//The rest of the pictures are there but will be hidden until we select the desired one
<img src="main-test-2.jpg" alt="" data-title="image-a">
<img src="main-test-3.jpg" alt="" data-title="image-a">
<img src="main-test-4.jpg" alt="" data-title="image-a">
</div>
<div >
<div >
<img src="preview-test-1.jpg" alt="" data-title="image-a">
</div>
<div >
<img src="preview-test-2.jpg" alt="" data-title="image-a">
</div>
<div >
<img src="preview-test-3.jpg" alt="" data-title="image-a">
</div>
<div >
<img src="preview-test-4.jpg" alt="" data-title="image-a">
</div>
And now when we click on preview-test-1.jpg we display main-test-1.jpg, when we click on preview-test-2.jpg we display main-test-2.jpg and so on
Can this be done?
CodePudding user response：
Similar to how you're handling the data-title, you can add another data attribute to the img tag that defines its "main" image, while the src remains the "preview" image.
<img src="https://www.previewimage.com/" data-main-src="https://placekitten.com/201/301">
Then in JS, instead of pulling the src of the img, read the data-main-src value and set that as the main src:
$('.main-image > img').attr('src', $(this).children('img').data('main-src'));
$('.img-to-select__item').click(function () {
$('.img-to-select__item').removeClass('selected');
$(this).addClass('selected');
$('.main-image > img').attr('src', $(this).children('img').data('main-src'));
$('.custom-carousel__title > span').html($(this).children('img').attr('data-title'));
});
// trigger this on page load so the "main" image is displayed instead of the preview.
$('.img-to-select__item.selected').click();.custom-carousel {
text-align: center;
}
.main-image > img {
width:50px;
}
.img-to-select > .img-to-select__item > img {
heigh:30px;
width: 30px;
}
.img-to-select {
overflow: hidden;
display: flex;
justify-content:space-around;
}
.img-to-select > .img-to-select__item {
display: flex;
justify-content:space-around;
}
.img-to-select > .img-to-select__item.selected {
border: 2px solid red;
