In modern web design, the use of various shapes and graphics has become an important part of the design style. In order to achieve these irregular shapes, jQuery, a powerful JavaScript framework, is also widely used.

Among them, irregular puzzle shapes have become a very popular design style. This article will introduce how to use jQuery to achieve irregular puzzle shapes. At the same time, we will also learn about the relevant technical background and implementation process.

Technical Background

Before introducing how to use jQuery to achieve irregular puzzle shapes, we need to understand some relevant technical background.

First of all, the clip-path property in CSS3 can create a path-based mask, where the path can be a rectangle, a circle, or even a custom path. Through the clip-path attribute, we can easily create various shapes, and this attribute also supports transition effects.

However, the compatibility of the clip-path attribute is not good, especially in IE browser. Therefore, we need to use a JavaScript framework to achieve cross-browser irregular puzzle shapes.

Implementation process

With the support of technical background, we can start to use jQuery to realize irregular puzzle shapes.

Step 1: HTML structure

First, we need to define the HTML structure according to design needs. In this example, we use a ul element to contain several li elements. Each li element represents a puzzle piece, and its content can be replaced at will. The code is as follows:

<ul class="puzzle">
  <li class="piece"><div>拼图块1</div></li>
  <li class="piece"><div>拼图块2</div></li>
  <li class="piece"><div>拼图块3</div></li>
  <li class="piece"><div>拼图块4</div></li>
  <li class="piece"><div>拼图块5</div></li>
  <li class="piece"><div>拼图块6</div></li>
</ul>

Step 2: CSS style

In order to achieve the irregular puzzle shape, we need to use the transform attribute in CSS3 to transform the puzzle pieces. Specifically, we need to use rotation, translate and other transformations to realize puzzle pieces in different directions and positions.

At the same time, in order to put the puzzle pieces at different stacking levels, we also need to use the z-index attribute. The code is as follows:

.puzzle {
  margin: 0;
  padding: 0;
  list-style: none;
  position: relative;
}
.piece {
  position: absolute;
  top: 0;
  left: 0;
  width: 200px;
  height: 200px;
  background-color: #fff;
  border: 1px solid #ccc;
  z-index: 1; /* 默认堆叠层级为1 */
  transition: all 0.5s ease; /* 过渡效果 */
}
.piece:nth-child(odd) {
  transform: rotate(30deg) translate(100px) rotate(-30deg); /* 变换1 */
  z-index: 2; /* 堆叠层级为2 */
}
.piece:nth-child(even) {
  transform: rotate(-30deg) translate(100px) rotate(30deg); /* 变换2 */
}
.piece:hover {
  z-index: 3; /* 鼠标悬停时堆叠层级为3 */
}

Step 3: JavaScript code

Next, we need to use jQuery to dynamically set the position, rotation angle and other attributes of the li element. The code is as follows:

$(document).ready(function() {
  var pieces = $(".puzzle .piece"); /* 获取所有拼图块 */
  var count = pieces.length; /* 记录总数 */
  var angle = 360 / count; /* 计算旋转角度 */

  /* 设置每个拼图块的位置、角度 */
  pieces.each(function(index) {
    var piece = $(this);
    var degree = angle * index;
    var posX = Math.sin(degree * Math.PI / 180) * 200;
    var posY = -Math.cos(degree * Math.PI / 180) * 200;
    piece.css({
      "left": posX + "px",
      "top": posY + "px",
      "transform": "rotate(" + degree + "deg)"
    });
  });
});

In the JavaScript code, we first get all the puzzle pieces and calculate the position and angle of each puzzle piece. Then, use the transform property in CSS3 to transform the puzzle pieces.

So far, we have successfully implemented a simple irregular puzzle shape using jQuery. The complete code is as follows:

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <title>jQuery不规则拼图形状</title>
  <style>
    .puzzle {
      margin: 0;
      padding: 0;
      list-style: none;
      position: relative;
    }
    .piece {
      position: absolute;
      top: 0;
      left: 0;
      width: 200px;
      height: 200px;
      background-color: #fff;
      border: 1px solid #ccc;
      z-index: 1; /* 默认堆叠层级为1 */
      transition: all 0.5s ease; /* 过渡效果 */
    }
    .piece:nth-child(odd) {
      transform: rotate(30deg) translate(100px) rotate(-30deg); /* 变换1 */
      z-index: 2; /* 堆叠层级为2 */
    }
    .piece:nth-child(even) {
      transform: rotate(-30deg) translate(100px) rotate(30deg); /* 变换2 */
    }
    .piece:hover {
      z-index: 3; /* 鼠标悬停时堆叠层级为3 */
    }
  </style>

    <li class="piece"><div>拼图块6</div></li>
  </ul>
  <script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
  <script>
    $(document).ready(function() {
      var pieces = $(".puzzle .piece"); /* 获取所有拼图块 */
      var count = pieces.length; /* 记录总数 */
      var angle = 360 / count; /* 计算旋转角度 */

      /* 设置每个拼图块的位置、角度 */
      pieces.each(function(index) {
        var piece = $(this);
        var degree = angle * index;
        var posX = Math.sin(degree * Math.PI / 180) * 200;
        var posY = -Math.cos(degree * Math.PI / 180) * 200;
        piece.css({
          "left": posX + "px",
          "top": posY + "px",
          "transform": "rotate(" + degree + "deg)"
        });
      });
    });
  </script>
