How to implement paging display of excel table with jquery

In today's information age, spreadsheets have become one of the indispensable tools in all walks of life. In these spreadsheets, because the amount of stored data is too large, in order to facilitate user use, we generally use paging to display and query data. So, how to quickly realize paging display of Excel tables through jQuery? This article will explain it to you in detail.

1. Introduction of paging plug-in

In order to realize the paging function, we first need to introduce a jQuery plug-in that supports display of paging. Here we choose to use the jPaginator plug-in. Introduce the jPaginator plug-in in the following way:

<script></script>
<script></script>
<link>

Among them, the CSS file of jPaginator is indispensable because it is the style file of this plug-in.

2. Table data format

Before we display the Excel table, we need to store the table data in JSON format and format it. The following is an example of the format of table data: The

{
    "total": 50, 
    "data": [
        {"Name": "张三", "Age": "18", "Sex": "男", "Address": "湖南长沙"}, 
        {"Name": "李四", "Age": "19", "Sex": "女", "Address": "广东深圳"}, 
        {"Name": "王五", "Age": "20", "Sex": "男", "Address": "北京朝阳"}, 
        {"Name": "赵六", "Age": "21", "Sex": "女", "Address": "上海浦东"}, 
        {"Name": "刘七", "Age": "22", "Sex": "男", "Address": "重庆江北"},
        ...
    ]
}

field total is used to store the total amount of data, and the data field is an array that stores paginated data.

3. Initialization of the paging plug-in

After introducing the code of the jPaginator plug-in, we need to initialize it so that it can match our table data. The initialization code is as follows:

// 定义分页数据，total为数据总量，perPage为每页显示的数量
var paginationData = {
    total: 0,
    perPage: 10,
    currentPage: 1,
    pageRange: 5,
    onPageClicked: function (pageIndex, event) {
        // 在这里调用ajax函数获取分页数据并更新表格
    }
};

// 调用jPaginator
$(".pagination").jPaginator(paginationData);

Next, we need to set the ajax calling method in the onPageClicked method to obtain the paging data. Here we use jQuery's $.ajax() method to make the call and pass the paging data to the background service.

onPageClicked: function (pageIndex, event) {
    $.ajax({
        url: "http://localhost:8000/getPageData",
        dataType: "json",
        type: "GET",
        data: {
            page: pageIndex,  // 当前页码
            perPage: this.options.perPage  // 每页显示的数量
        },
        success: function (data) {
            showPageData(data);  // 更新表格数据
        }
    });
}

4. Update table data

After successfully obtaining the paging data, we need to update it into the table. Here we use the following code to build the HTML code of the table:

function buildTableHtml(data) {
    var html = "

";     for (var i = 0, length = data.length; i " +                 "" +                 "" +                 "" +                 "" +                 "";     }     html += "

姓名	年龄	性别	住址
" + data[i].Name + "	" + data[i].Age + "	" + data[i].Sex + "	" + data[i].Address + "

";     return html; }

After building the HTML code of the table, we need to add it to the page. Use the following code to update the table:

function showPageData(data) {
    var tableHtml = buildTableHtml(data);
    $(".table-wrapper").html(tableHtml);
}

5. Summary

Through the above code implementation, we can quickly implement the paging display function of the Excel table through jQuery. Among them, the use of jPaginator can quickly implement the paging function, and the use of jQuery's $.ajax() method can quickly obtain paging data. I hope that the content introduced in this article can be helpful to the majority of developers in the development process.
