Jump to page number in jquery

With the continuous development of the Internet, web pages are increasingly inseparable from front-end technology, and jQuery, as an excellent front-end framework, is widely used in web development. In web design, it is often necessary to implement the function of jumping to a specified page number. Next, we will introduce the method of jumping to a page number in jQuery.

1. Get the current page number

Before implementing the jump page number, you need to get the current page number first. You can locate the current page number element in the paging control through class or id, and then obtain its text content.

For example, in the following code, the class selector is used to obtain the element named "current" and obtain its text content, which is the current page number:

var currentPage = $(".current").text();

2. Bind click event

Next, you need to bind a click event to each page number in the paging control, so that the page jump can be triggered when the user clicks on the page number.

You can use the on() function provided by jQuery to bind events to elements. For example, in the following code, use the class selector to obtain all elements named "page" and bind click events to them:

$(".page").on("click", function () {
  //TODO:处理点击事件
});

3. Handle click events

When the user clicks on the page number When using numbers, you need to obtain the page number clicked by the user and jump to the corresponding page. In the click event, use the this keyword to obtain the page number element clicked by the user, and obtain its text content, that is, the page number number clicked by the user.

For example, in the following code, use the this keyword to obtain the page number element clicked by the user and obtain its text content:

var target = $(this).text();

Next, pass the obtained page number number as a parameter to Jump function jumpToPage() uses the window.location.href attribute provided by JavaScript to jump to the page.

For example, in the following code, the jump function jumpToPage() is defined, and the function is called in the click event to jump to the page:

function jumpToPage(targetPage) {
  //TODO: 跳转到指定页码
  window.location.href = "http://www.example.com/page/" + targetPage;
}

$(".page").on("click", function () {
  var target = $(this).text();
  jumpToPage(target);
});

4. Complete example

Combining the above steps, we can give a complete jQuery example to jump to the page number, as shown below:

//获取当前页码
var currentPage = $(".current").text();

//定义跳转函数
function jumpToPage(targetPage) {
  window.location.href = "http://www.example.com/page/" + targetPage;
}

//为页码数字绑定点击事件
$(".page").on("click", function () {
  var target = $(this).text();
  jumpToPage(target);
});

Summary

Through the above steps, we can achieve a simple and practical jump Turn page number function. However, it should be noted that this article is only a simple example, and more complex logic and error handling may be required in actual development. At the same time, if you are using a jQuery-based paging plug-in, there may be a more convenient and customizable method to implement the page jump function.
