How to realize form page without jumping to pagination in php

With the rapid development of Internet technology, form pages have become a common requirement for website development. In the form page, it is usually necessary to implement the paging function to better display the data. However, the traditional paging method requires jumping to a new page, which may reduce user experience and website performance. In PHP, we can use AJAX technology and paging plug-ins to realize form pages without jumping to paging, so that users can operate the page more smoothly, and at the same time, it also improves the efficiency of the website.

1. AJAX Technology

AJAX (Asynchronous JavaScript And XML) is a technology for dynamic updating on Web pages. It can update part of the data without refreshing the entire page. In this way, we can implement paging function on the form page without jumping to a new page.

When using AJAX technology to implement paging, we need to first introduce the jQuery library and paging plug-in. Among them, jQuery is one of the most popular JavaScript libraries currently, and paging plug-ins can help us quickly implement paging functions, such as the commonly used jQuery Paging plug-in.

Next, let’s take a look at how to use AJAX and paging plug-ins to achieve form pages without jumping to pagination.

2. Implementation steps

1. Preparation work

First, we need to add an area for displaying data and an area for displaying paging in the form page . Here we can use div elements to create two areas.

<div id="dataArea"></div>
<div id="pagination"></div>

2. Send an AJAX request

Next, we need to send an AJAX request in the JavaScript code to get the paginated data. We can use jQuery's $.ajax() method to send a request and pass the necessary parameters, such as the current page number, the number of data items displayed on each page, etc.

function loadData(page) {
    $.ajax({
        type: "GET",
        url: "data.php",
        data: {
            page: page,
            pageSize: 10
        },
        success: function(data) {
            // 分页数据处理代码
        },
        error: function() {
            alert("获取数据失败！");
        }
    });
}

When sending a request, we need to specify the request type and request address, and pass the necessary parameters. Here, we use the GET request method, specify the data request page as data.php, and pass the current page number and the number of data items displayed on each page as two parameters.

3. Processing paging data

When the request is successful, we can process the returned data in the success callback function. Here, we can use the methods provided in the paging plug-in to render the data to the corresponding location on the form page.

function loadData(page) {
    $.ajax({
        type: "GET",
        url: "data.php",
        data: {
            page: page,
            pageSize: 10
        },
        success: function(data) {
            // 将数据渲染到数据区
            $("#dataArea").html(data.data);

            // 渲染分页
            $("#pagination").paging({
                currentPage: page,
                totalPage: data.totalPage,
                callback: function(page) {
                    loadData(page);
                }
            });
        }
    });
}

Here, we first render the data returned after the request is successful into the data area (the data may need to be formatted or otherwise processed according to the actual situation), and then use the paging() of the paging plug-in Method, render the paging component and pass the current page number and total page number to the paging component. Finally, we specify the paging callback function. When the user clicks the paging button, the loadData() function will be called again to obtain the corresponding data.

4. Initialize the page

In order to display the paging data when the page is loaded for the first time, we need to manually call the loadData() function after the page is loaded and pass the initial page number parameter.

$(function() {
    loadData(1);
});

So far, we have successfully implemented the function of form page without jumping to pagination. Users can freely switch page numbers in the paging component, and the data area will automatically update the corresponding data according to changes in page numbers.

3. Summary

Through the above implementation method, we can quickly and simply implement the non-jump paging function in the form page, so that users can operate the page more smoothly, and Improve website efficiency. Of course, during actual use, some modifications and improvements to the code need to be made based on specific business needs to achieve the best user experience.
