jquery jump page without refreshing

jQuery is a popular JavaScript library often used to build websites in a dynamic, interactive way. By using jQuery, you can make your website more attractive and user-friendly while keeping it responsive. When it comes to JavaScript and web page production, jumping to a page without refreshing is a very common task, and this article will introduce you to how to use jQuery to achieve it.

What is a non-refresh jump page?

Normally, when a user clicks a link or submits a form, the browser refreshes the entire page. This can introduce unnecessary delays that degrade the user experience. Refreshless redirects mean you can redirect users to a new page without refreshing the entire page.

Why use non-refresh jump page?

In modern web applications, refresh-free jump pages have become a very important part. This is because:

• Better user experience: Refresh-free jump pages do not refresh the entire page, which means users no longer have to wait for the entire page to reload, saving time and unnecessary trouble.

• Fast loading: Since the refresh-free jump page can load page content asynchronously, it can speed up page loading and give users a better experience.

• SEO Optimization: Since the entire page will not be completely refreshed, refreshing the jump page can improve the accessibility of the page, allowing Google and other search engines to better index your page content.

Using jQuery to implement refresh-free jump pages

Now that we have learned about refresh-free jump pages and their advantages, let us now start to see how to use jQuery to implement it.

Using jQuery is very easy, just click a few lines of code to complete. Here are the simple steps to achieve a non-refresh jump page:

• Create an HTML page.

• Add the jQuery library in the script tag. You can download the jQuery library from the jQuery official website.

• Create a function to handle AJAX requests.

• Use jQuery to define events to trigger the function of jumping to the page without refreshing

Let's break down this process in more detail.

1. Create an HTML page

First, you need to create an HTML page, which must contain the following content:

<button id="btn">跳转页面</button>

<script>
    $(document).ready(function() {
        // your code goes here
    });
</script>

Here you can see that we have added the necessary HTML tags, along with a button and a script tag to contain the JavaScript code.

2. Add jQuery library

Next, you need to add jQuery library. Here, we will use jQuery CDN to get the jQuery library.

This will be from jQuery official The website obtains the jQuery library and accelerates the acquisition through CDN.

3. Create a function to handle AJAX requests

Next, in jQuery, you need to write a function to handle AJAX requests. For example, you can use the following code:

function redirectToPage(url) {

$.ajax({
    url: url,
    type:'GET',
    success: function(data) {
        $('body').html(data);
    },
    error:function (){}

});
}

This function will accept a URL parameter and use AJAX request sends it to the server. If the request is successful, the returned data will be inserted into the HTML body element.

4. Use jQuery to define events

Finally, you need to add jQuery code and define events to trigger the function of jumping the page without refreshing:

$(document). ready(function() {

$('#btn').click(function() {
    redirectToPage('http://www.example.com');
});

});

Here, the redirectToPage() function is triggered by listening to the click event of the button, and the URL 'http://www.example. com' is passed to it as a parameter.

In this way, when the user clicks the button, the web page will jump to a new page without refreshing.

Summary:

jQuery is a very powerful tool that allows developers to efficiently build interactive web applications. Refresh-free jump pages are an important factor in improving application performance and user experience. This article briefly introduces you how to use jQuery to achieve refresh-free jump pages, thereby building a more interactive web application. Using these basic routines, you can easily start using jQuery to write very complex web applications.
