jQuery is a commonly used JavaScript library used to simplify the operation, processing and event registration of HTML documents. In web design, the scroll view is a very important element, which can slide different elements on the page to better display the content. In jQuery, such a view can be easily created using the scrollview plugin. This article will introduce how to use the scrollview plug-in with jQuery.

1. What is scrollview?

ScrollView is a plug-in in jQuery Mobile that allows the display of an entire content within a fixed area and enables horizontal and vertical scrolling operations. It can be used as a container to accommodate other elements, so it can replace the traditional frame framework.

2. Examples of using scrollview

The following is a simple code example for using scrollview to display images:

<!DOCTYPE html>
<html>
<head>
    <title>使用ScrollView</title>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="https://cdn.bootcss.com/jquery-mobile/1.4.5/jquery.mobile.min.css">
    <script src="https://cdn.bootcss.com/jquery/1.12.4/jquery.min.js"></script>
    <script src="https://cdn.bootcss.com/jquery-mobile/1.4.5/jquery.mobile.min.js"></script>
</head>
<body>

<div data-role="page">
    <div data-role="header">
        <h1 id="ScrollView示例">ScrollView示例</h1>
    </div>
    <div data-role="content">
        <div id="wrapper">
            <div id="scroller">
                <ul data-role="listview">
                    <li><img  src="/static/imghwm/default1.png"  data-src="1.png"  class="lazy" alt="How to use scrollview with jquery" ></li>
                    <li><img  src="/static/imghwm/default1.png"  data-src="2.png"  class="lazy" alt="How to use scrollview with jquery" ></li>
                    <li><img  src="/static/imghwm/default1.png"  data-src="3.png"  class="lazy" alt="How to use scrollview with jquery" ></li>
                    <li><img  src="/static/imghwm/default1.png"  data-src="4.png"  class="lazy" alt="How to use scrollview with jquery" ></li>
                    <li><img  src="/static/imghwm/default1.png"  data-src="5.png"  class="lazy" alt="How to use scrollview with jquery" ></li>
                    <li><img  src="/static/imghwm/default1.png"  data-src="6.png"  class="lazy" alt="How to use scrollview with jquery" ></li>
                    <li><img  src="/static/imghwm/default1.png"  data-src="7.png"  class="lazy" alt="How to use scrollview with jquery" ></li>
                    <li><img  src="/static/imghwm/default1.png"  data-src="8.png"  class="lazy" alt="How to use scrollview with jquery" ></li>
                </ul>
            </div>
        </div>
    </div>
    <div data-role="footer">
        <h4 id="footer">footer</h4>
    </div>
</div>

<script type="text/javascript">
    $(function(){
        $("#wrapper").css("height",($(window).height()-62)+"px");
        var myScroll = new IScroll('#wrapper', { mouseWheel: true });
    });
</script>

</body>
</html>

The above code uses three library files: jQuery, jQuery Mobile and iScroll. Among them, iScroll is a JavaScript library that provides customizable scroll bars that can be scrolled through gestures, scroll wheels, etc.

In the html file, the jQuery and jQuery Mobile libraries are first introduced. Then, use the data-role attribute to assign specific roles to elements in the page, such as header, content, footer, etc. In this example, the header places a title, and the content places an element with the id of wrapper, which contains an element with the id of scroller, which contains an unordered list based on the listview. Finally, footer places a footer.

In the javascript code, the height is set for the wrapper element through the css method, and an instance is created through IScroll. The myScroll object here can be used to manage sliding.

3. Scrollview implementation principle

To understand the implementation process of scrollview, you need to understand its basic principles. It takes a fixed-size container and embeds a large scrollable area within the container. In this way, the size of the container acts as a window and only displays a part of the scrollable area, while the sliding operation changes the position of the scrollable area in the container, ultimately realizing the sliding of the view.

4. Common problems and solutions of scrollview

When using scrollview, you may encounter some common problems, especially the compatibility issues with different browsers, devices and operating systems. . The following are some solutions:

Compatibility issues: It is strongly recommended to use jQuery Mobile version 1.4.5 or above library files;
Container size issues: The size of the container should be based on different Dynamic adjustment of the device;
Container nesting problem: other scrollable elements should not appear in the container;
Scroll bar problem: When using iScroll, you can adjust the scroll bar through the iScroll option Make settings.

5. Summary

Through the introduction of this article, readers should be able to understand how jQuery uses the scrollview plug-in to create a scroll view, and learn how to adjust related technologies and compatibility issues. For developing high-quality web applications, mastery of these technologies is very important. We hope that through this article, readers can deepen their understanding of these knowledge points and better apply them in practice.
