jQuery Mobile is a framework for creating mobile applications that makes it easier to create web applications based on mobile devices. Jumping to other pages is a fairly common operation during the development of mobile web applications. However, if not handled, it can cause some problems. In this article, I will introduce how to use jQuery Mobile to jump to the page.

1. Problems in jQuery Mobile page jump

The impact of page jump on performance

On mobile devices, page jumps usually It is much slower than on a computer, and during the jump, the JavaScript and CSS files already loaded in the page will also be reloaded. This will lead to performance degradation and affect user experience, so some measures need to be taken to mitigate the impact of page jumps on performance.

Page jumps may cause JavaScript errors

If you open a new page through a simple jump link, it may cause JavaScript errors because the page has not been fully loaded. In some cases, if jump links are not processed, it may cause confusion between pages or other problems.

Jump links are not suitable for handheld devices

Jump links are not friendly to users on handheld devices because users need to keep clicking on the link to open it New page, this can be very tedious. At the same time, since the operating area of handheld devices is small, it is easy to click on links by mistake.

2. Use jQuery Mobile to achieve page jump

Generally, we can use URL jump to achieve page jump. jQuery Mobile provides some methods to implement page jumps. These methods can help us avoid the above problems and make page jumps more smooth and user-friendly.

Use dynamic loading to avoid JavaScript errors

Dynamic loading is a way for jQuery Mobile to solve JavaScript errors in page jumps. Compared with simply opening a link, dynamic loading allows new pages to be loaded after the page is fully loaded, and JavaScript and CSS files can be preloaded before switching to avoid JavaScript errors.

Use Ajax loading to avoid performance issues

Ajax loading can load only the necessary files when a new page loads without reloading the entire page. This can greatly reduce the performance impact of page jumps. jQuery Mobile can enable Ajax loading by adding the data-ajax attribute to the jump link.

Use Transitions to enhance user experience

Transitions is a technology used to enhance user experience and can provide a smooth transition effect when the page jumps. jQuery Mobile provides a wealth of Transitions effects, and you can choose the appropriate transition effect according to the application scenario.

3. Example Demonstration

The following is a simple example that demonstrates how to use jQuery Mobile to achieve page jump.

<!DOCTYPE html>
<html>
  <head>
    <title>jQuery Mobile页面跳转示例</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css">
    <script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
    <script src="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
  </head>
  <body>
    <div data-role="page" id="page1">
      <div data-role="header">
        <h1>Page 1</h1>
      </div>
      <div data-role="content">
        <p>Hello, this is page 1.</p>
        <p><a href="#page2" data-transition="slide">Go to Page 2</a></p>
      </div>
      <div data-role="footer">
        <h4>Page 1 Footer</h4>
      </div>
    </div>
    <div data-role="page" id="page2">
      <div data-role="header">
        <h1>Page 2</h1>
      </div>
      <div data-role="content">
        <p>Hello, this is page 2.</p>
        <p><a href="#page1" data-transition="slide" data-direction="reverse">Go back to Page 1</a></p>
      </div>
      <div data-role="footer">
        <h4>Page 2 Footer</h4>
      </div>
    </div>
  </body>
</html>

Copy after login

In this example, we have two pages, Page1 and Page2. In Page1, there is a link that jumps to Page2; in Page2, there is a link that returns to Page1.

Set the jump link through the href attribute, and use the data-transition attribute to set the page transition effect. In this example, we selected the slide effect. Use the data-direction attribute to set the direction of the transition, which can be "reverse" or empty.
