How to achieve the rotation effect of div with jquery

With the continuous advancement of Internet technology, the effects of web design are becoming more and more cool, among which the rotation effect is one of the most popular designs at present. In this article, we will explore how to achieve a div rotation effect using jQuery.

jQuery is a very popular JavaScript library that provides a rich API to make JavaScript programming more convenient and simple. In this article, we will use jQuery's rotate() function to achieve the rotation effect of divs.

First, create a div element in HTML:

<div id="mydiv">这是一个旋转的div元素</div>

Then, add the following code in JavaScript:

$(function(){
  // 获取div元素
  var mydiv = $('#mydiv');
  
  // 设置旋转角度
  var angle = 0;
  
  // 每隔50毫秒旋转10度
  setInterval(function(){
    angle += 10;
    mydiv.rotate(angle);
  }, 50);
});

In the above code, we first use jQuery The $() function gets the div element with the id mydiv and saves it to the variable mydiv. Then, we defined a variable angle to save the rotation angle, with an initial value of 0. Next, we use the setInterval() function to increase the value of angle by 10 every 50 milliseconds, and use the rotate() function to rotate the div element by the corresponding angle.

In the above code, we use the rotate() function to rotate the div element. This function is provided by jQrotate, another jQuery plugin. This plugin is a simple yet powerful tool that allows you to easily rotate and scale objects on the web using jQuery.

In addition to the above code, we can also use some other parameters to adjust the behavior of jQuery's rotate() function as needed. For example, we can set the position of the rotation center, the length of rotation, and so on.

In summary, jQuery’s rotate() function can bring very rich effects to web page design. By mastering this function, you can easily achieve various rotation effects, making the page more vivid and increasing the user experience.
