为了提高用户体验度,在一些电商网站和家居网站上我们会看到,一张图片中显示多种商品,点击每个商品可以弹出对应商品的简单介绍,包括价格等等,设计非常的人性化,今天我们通过实例给大家分享使用jQuery插件来实现这一效果。

先给大家展示下效果图:

效果演示          源码下载

HTML

首先,我们加载jQuery库和easypin插件。

<script src="jquery.min.js"></script> 
<script src="jquery.easing.min.js"></script> 
<script src="jquery.easypin.min.js"></script> 
Copy after login

接着,我们准备一张图片,这是一张展示多个模特服装鞋子包包内的电商图片,注意我们给图片一个easypin-id属性,它用来标记当前图片id,用来被后面插件调用。

<img src="fashion.jpg" class="pin" width="900" easypin-id="demo_image_1" /> 
Copy after login

我们还需要制作一个用于弹出显示商品信息的隐藏层,使用属性easypin-tpl来标记弹出层。标签popover是弹出层元素,标签marker是标注点元素。再配合CSS来让弹出层有一个漂亮的外观。

<div style="display:none;" easypin-tpl> 
<popover> 
<div class="exPopoverContainer"> 
<div class="popBg borderRadius"></div> 
<div class="popBody"> 
<div class="arrow-down" style="top: 170px;left: 13px;"></div> 
<h1>{[name]}</h1> 
<div class="popHeadLine"></div> 
<div class="popContentLeft"> 
{[description]} 
<br /> 
<br /> 
<a href="#">Buy</a> 
<a href="#">More info</a> 
</div> 
<div class="popContentRight">{[price]}</div> 
</div> 
</div> 
</popover> 
<marker> 
<div class="marker2 element-animation"> 
</div> 
</marker> 
</div> 
Copy after login

jQuery

插件提供了easypin()和easypinShow()两个方法,我们使用easypinShow()来展示图片标注效果,它有一个data选项,支持json格式,它定义标注点相关数据,包括坐标位置,商品名称、描述和价格,这些数据可以是后台统一生成。它还提供了很多其他选项和回调函数,请看下面的代码。

$(document).ready(function(){ 
$('.pin').easypinShow({ 
data: '{"demo_image_1":{"0":{"name":"商品名称","description":"商品描述信息. ","price":"$67","coords":{"lat":"800","long":"228"}},"1":{"name":"Pierre Cardin","description":"Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore. ","price":"$98","coords":{"lat":"597","long":"357"}},"2":{"name":"Pierre Cardin","description":"Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. ","price":"$100","coords":{"lat":"241","long":"352"}},"canvas":{"src":"fashion.jpg","width":"1000","height":"625"}}}', 
responsive: false, 
variables: { 
firstname: function(canvas_id, pin_id, data) { 
//console.log(canvas_id, pin_id, data); 
return data; 
}, 
surname: function(canvas_id, pin_id, data) { 
//console.log(canvas_id, pin_id, data); 
return data; 
} 
}, 
popover: { 
show: false, 
animate: true 
}, 
each: function(index, data) { 
return data; 
}, 
error: function(e) { 
console.log(e); 
}, 
success: function() { 
console.log('ok'); 
} 
}); 
}); 
Copy after login

easypin()可以用来实现图片标注效果,您可以在图片上任意位置标注,然后再弹出层中填写标注信息提交即可,支持拖动等等

一款简单的jQuery图片标注效果附源码下载到此就给大家介绍完了,希望对大家有所帮助!

The Evolution of JavaScript: Current Trends and Future Prospects The Evolution of JavaScript: Current Trends and Future Prospects Apr 10, 2025 am 09:33 AM

The latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.

JavaScript Engines: Comparing Implementations JavaScript Engines: Comparing Implementations Apr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Python vs. JavaScript: The Learning Curve and Ease of Use Python vs. JavaScript: The Learning Curve and Ease of Use Apr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

From C/C   to JavaScript: How It All Works From C/C to JavaScript: How It All Works Apr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.
