Easily learn the jQuery plug-in EasyUI EasyUI to implement drag-and-drop products and place them in the shopping cart_jquery
在本文中,我们将向您展示如何创建一个启用用户拖动和放置用户想买的商品的购物车页面,购物篮中的物品和价格将更新,分享给大家,具体内容如下:
效果图:
具体代码如下
显示页面上的商品:
<ul class="products"> <li> <a href="#" class="item"> <img src="/static/imghwm/default1.png" data-src="images/shirt1.gif" class="lazy"/ alt="Easily learn the jQuery plug-in EasyUI EasyUI to implement drag-and-drop products and place them in the shopping cart_jquery" > <div> <p>Balloon</p> <p>Price:$25</p> </div> </a> </li> <li> <a href="#" class="item"> <img src="/static/imghwm/default1.png" data-src="images/shirt2.gif" class="lazy"/ alt="Easily learn the jQuery plug-in EasyUI EasyUI to implement drag-and-drop products and place them in the shopping cart_jquery" > <div> <p>Feeling</p> <p>Price:$25</p> </div> </a> </li> <!-- other products --> </ul>
正如您所看到的上面的代码,我们添加一个包含一些
- 元素来显示商品。所有商品都有名字和价格属性,它们包含在
元素中。
创建购物车:
<div class="cart"> <h1 id="Shopping-Cart">Shopping Cart</h1> <table id="cartcontent" style="width:300px;height:auto;"> <thead> <tr> <th field="name" width=140>Name</th> <th field="quantity" width=60 align="right">Quantity</th> <th field="price" width=60 align="right">Price</th> </tr> </thead> </table> <p class="total">Total: $0</p> <h2 id="Drop-here-to-add-to-cart">Drop here to add to cart</h2> </div>
我们使用数据网格(datagrid)来显示购物篮中的物品。
拖动克隆的商品:
$('.item').draggable({ revert:true, proxy:'clone', onStartDrag:function(){ $(this).draggable('options').cursor = 'not-allowed'; $(this).draggable('proxy').css('z-index',10); }, onStopDrag:function(){ $(this).draggable('options').cursor='move'; } });
请注意,我们把 draggable 属性的值从 'proxy' 设置为 'clone',所以拖动元素将由克隆产生。
放置选择商品到购物车中
$('.cart').droppable({ onDragEnter:function(e,source){ $(source).draggable('options').cursor='auto'; }, onDragLeave:function(e,source){ $(source).draggable('options').cursor='not-allowed'; }, onDrop:function(e,source){ var name = $(source).find('p:eq(0)').html(); var price = $(source).find('p:eq(1)').html(); addProduct(name, parseFloat(price.split('$')[1])); } }); var data = {"total":0,"rows":[]}; var totalCost = 0; function addProduct(name,price){ function add(){ for(var i=0; i<data.total; i++){ var row = data.rows[i]; if (row.name == name){ row.quantity += 1; return; } } data.total += 1; data.rows.push({ name:name, quantity:1, price:price }); } add(); totalCost += price; $('#cartcontent').datagrid('loadData', data); $('div.cart .total').html('Total: $'+totalCost); }
每当放置商品的时候,我们首先得到商品名称和价格,然后调用 'addProduct' 函数来更新购物篮。
EasyUI实现拖放商品放置购物车的功能就介绍到这,有了本文为大家提供的实例,相信大家应该很轻松的就可以实现拖放商品放置购物车的模块设计,谢谢大家的阅读。

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.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

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.

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.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

JavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.
