jQuery is a well-known JavaScript library that provides many convenient methods that allow us to operate HTML and CSS more conveniently, including creating and manipulating div elements. This article will introduce how to create div elements using jQuery.
1. Introduce the jQuery library into the HTML page
First, introduce the jQuery library into the HTML page. You can download the latest version of the library file from the jQuery official website, or you can get it directly from the CDN, for example:
<script src="https://cdn.bootcss.com/jquery/3.4.1/jquery.min.js"></script>
In this way, we can use the methods provided by jQuery in the page.
2. Use jQuery to create div elements
jQuery provides several methods to create div elements, the most commonly used of which are the $()
method and jQuery( )
method. These two methods are interchangeable because they are both calls to jQuery functions, which themselves are defined through the $
notation.
The following are sample codes for creating div elements in two ways:
// 使用$()方法创建div元素 var $div1 = $('<div></div>'); $div1.attr('id', 'div1'); $div1.text('这是一个使用$()方法创建的div元素。'); $('body').append($div1); // 将该div元素添加到<body>中 // 使用jQuery()方法创建div元素 var $div2 = jQuery('<div/>', { id: 'div2', text: '这是一个使用jQuery()方法创建的div元素。' }); $('body').append($div2); // 将该div元素添加到<body>中
As shown in the above code, we can follow the steps below:
- Use
$()
method orjQuery()
method to create a div element. Use the tag name<div> in brackets to indicate that a div element needs to be created. <li>Use the <code>attr()
method or pass in an object in thejQuery()
method to set the id attribute and text content of the div element. - To add the div element to the page, you can use the
append()
method. - If an element with the same id is defined in HTML, the id attribute cannot be used to define the div element created by jQuery. You can use class attributes or other naming to avoid conflicts.
- If you want to create a div element with a specific style, you can describe the element in a style sheet, or add the style dynamically in JavaScript.
-
When creating a div element, we can also add more elements inside it, for example:
var $div1 = $('<div class="outer"></div>'); $div1.attr('id', 'div1'); $div1.text('这是一个使用$()方法创建的div元素。'); var $innerDiv = $('<div class="inner"></div>'); $innerDiv.text('这是一个在内部添加的子div元素。'); $div1.append($innerDiv); $('body').append($div1);
In this example, we create a div element with
class
attribute of theouter
div element, and a child div element with theclass
attribute ofinner
is added to it. As you can see, we only need to use theappend()
method to add the child element to the parent element.
Among them, the $()
method is more intuitive to create a div element, while the jQuery()
method uses an object to set the div element at once of multiple attributes.
3. Precautions for creating div elements with jQuery
4. Summary
jQuery is a very powerful JavaScript library that can perform HTML and CSS operations through the methods it provides, including creating and operating div elements. . You can easily create a div element using the $()
method or the jQuery()
method, and you can use attributes or objects to set the id, class, text content, etc. of the element. This element can be added to the page using the append()
method. When creating a div element, you can add more child elements inside it. Through these methods, we can carry out Web development more conveniently and quickly.
