How to achieve switching page transition animation effect in jquery

With the continuous advancement of front-end technology, animation effects have attracted more and more attention from developers. Among them, page switching transition animation is a very practical animation effect, which can make switching between pages smoother and more natural, giving users a better user experience. In the process of realizing page switching transition animation, jQuery is a very practical tool library. This article will introduce how to use jQuery to realize page switching transition animation effect.

Prerequisite knowledge

Before you start to implement page switching transition animation, you need to master the following knowledge:

• Basic knowledge of HTML, including HTML elements, attributes, etc.
• Basic knowledge of CSS, including CSS selectors, style attributes, etc.
• Basic knowledge of jQuery, including selectors, event binding, animation effects, etc.

Implementation steps

1. Writing HTML code

First of all, there need to be at least two modules (such as two divs) in the page, each module containing different content. The code example is as follows:

<div class="page1">
    <h1>这是第一页</h1>
    <p>这是第一页的内容</p>
</div>

<div class="page2">
    <h1>这是第二页</h1>
    <p>这是第二页的内容</p>
</div>

2. Write CSS style

For the above code, you need to write the corresponding CSS style for each module. Taking the above code as an example, write the following CSS style:

.page1 {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-color: #ff6666;
    opacity: 1;
    z-index: 1;
}

.page2 {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-color: #66ccff;
    opacity: 0;
    z-index: 0;
}

In the above CSS style, page1 and page2 are used to define the styles of two modules respectively. The z-index value of page1 is larger than that of page2. The value is large, that is, page1 is located above page2. At the same time, the opacity value of page2 is 0, that is, the page2 module is invisible at the beginning.

3. Write jQuery code

Next, you need to write jQuery code so that the transition animation effect can be achieved when the page is switched. Here, jQuery's animate() method is used to achieve the transition animation effect. The specific code example is as follows:

$(document).ready(function() {
    $('.page2').hide();

    $('.page1').click(function() {
        $('.page1').animate({
            opacity: 0
        }, 500, function() {
            $('.page1').hide();
            $('.page2').show();
            $('.page2').animate({
                opacity: 1
            }, 500);
        });
    });

    $('.page2').click(function() {
        $('.page2').animate({
            opacity: 0
        }, 500, function() {
            $('.page2').hide();
            $('.page1').show();
            $('.page1').animate({
                opacity: 1
            }, 500);
        });
    });
});

In the above code, the page2 module is first hidden. When the user clicks on the page1 module, the click event of page1 will be executed, and the opacity value of the page1 module will be changed from 1 to 0 through the animate() method, achieving a transition animation effect within 500 milliseconds. When the animation effect is completed, hide the page1 module, display the page2 module, and use the animate() method to change the opacity value of the page2 module from 0 to 1 to achieve the transition animation effect within 500 milliseconds.

When the user clicks on the page2 module, the click event of page2 is executed, and the animate() method is also used to achieve the transition animation effect.

Achieve effect

Through the above steps, you can achieve the transition animation effect of page switching. When the user clicks on a module on the page, a smooth and natural transition animation will appear between pages.

Summary

This article introduces how to use jQuery to achieve page switching transition animation effects. By using the animate() method in jQuery, you can easily achieve the transition animation effect of page switching, bringing a better user experience to users. At the same time, you also need to master basic knowledge such as HTML, CSS and jQuery to fully grasp the implementation process.
