Use jQuery to realize interactive and powerful focus chart display

Title: Using jQuery to achieve interactive and powerful focus chart display

In web design, focus chart display is a common way to attract the user's attention. power to convey important information. Using jQuery, an excellent JavaScript library, we can implement a powerful and interactive focus map display, and implement this function through code examples.

1. HTML structure

First, we need to create an HTML structure to accommodate the focus map display area. The following is a simple HTML structure example:

<div class="slideshow">
    <div class="slides">
        <img src="/static/imghw/default1.png"  data-src="image1.jpg"  class="lazy" alt="Image 1">
        <img src="/static/imghw/default1.png"  data-src="image2.jpg"  class="lazy" alt="Image 2">
        <img src="/static/imghw/default1.png"  data-src="image3.jpg"  class="lazy" alt="Image 3">
    </div>
    <div class="controls">
        <span class="prev">Previous</span>
        <span class="next">Next</span>
    </div>
</div>

2. CSS style

Next, use CSS to beautify the style of the focus map display area. The following is a simple CSS style example:

.slideshow {
    position: relative;
    width: 600px;
    height: 400px;
    overflow: hidden;
}
.slides {
    display: flex;
    width: 300%;
    transition: transform 0.5s ease-in-out;
}
.slides img {
    width: 100%;
    height: 100%;
}
.controls {
    position: absolute;
    top: 50%;
    left: 10px;
    transform: translateY(-50%);
}
.controls span {
    cursor: pointer;
    margin: 0 10px;
}

3. jQuery to implement interactive functions

Now, we will use jQuery to implement interactive functions in the focus map display area. The following is a simple jQuery code example:

$(document).ready(function() {
    var currentSlide = 0;
    var slideWidth = $('.slides').width();
    
    $('.next').click(function() {
        if (currentSlide < 2) {
            currentSlide++;
            $('.slides').css('transform', 'translateX(' + (-currentSlide * slideWidth) + 'px)');
        }
    });
    
    $('.prev').click(function() {
        if (currentSlide > 0) {
            currentSlide--;
            $('.slides').css('transform', 'translateX(' + (-currentSlide * slideWidth) + 'px)');
        }
    });
});

In this code, we use jQuery to listen to the click events of the previous page and next page buttons, and when clicked, change the currently displayed image.

Through the above HTML, CSS and jQuery code examples, we can implement a basic focus map display with powerful interactive functions. Of course, we can further expand and optimize this function according to actual needs to make the focus map display more rich and attractive.
