In web development, using jQuery is very common. jQuery is a lightweight, fast and feature-rich JavaScript library that simplifies the operation of JavaScript and provides many convenient and practical methods and functions. In the actual development process, we often encounter situations where we need to dynamically add elements to an HTML element. This article will introduce some practical jQuery methods to help you add elements to a div, and provide specific code examples.
First, you need to ensure that the jQuery library is introduced into the project. Add the following code to the HTML file:
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
Next, we will add elements to a div through several different methods to demonstrate their usage.
Method 1: Use the append() method
// 创建一个新的元素 var newElement = $("<p>New element added using append()</p>"); // 将新元素添加到id为container的div中 $("#container").append(newElement);
In the above code, a new p element is first created, and then the new element is added to the id with the id using the append() method. in the div of the container.
Method 2: Use the appendTo() method
// 创建一个新的元素 var newElement = $("<p>New element added using appendTo()</p>"); // 将新元素添加到id为container的div中 newElement.appendTo("#container");
Using the appendTo() method can also add elements to a div, but the method of calling the method is different.
Method 3: Use the html() method
// 创建要添加的HTML内容 var newHTML = "<p>New element added using html()</p>"; // 将HTML内容添加到id为container的div中 $("#container").html(newHTML);
The html() method can be used to set the HTML content of the specified element, which can be an HTML string or an existing element. Here we directly pass in the HTML content to be added.
Method 4: Use the prepend() method
// 创建一个新的元素 var newElement = $("<p>New element added using prepend()</p>"); // 将新元素添加到id为container的div中的开头 $("#container").prepend(newElement);
The usage of the prepend() method is similar to append(), except that it will add the element to the beginning of the specified element.
Method 5: Use the before() method
// 创建一个新的元素 var newElement = $("<p>New element added using before()</p>"); // 将新元素添加到id为container之前 $("#container").before(newElement);
Use the before() method to add a new element before the specified element.
These are some commonly used jQuery methods for adding elements to divs. You can choose the appropriate method to operate page elements according to actual needs. The powerful functions of jQuery can help simplify code and improve development efficiency. I hope these examples can help you better use jQuery to process page elements.

实现方法:1、用“$("img").delay(毫秒数).fadeOut()”语句,delay()设置延迟秒数;2、用“setTimeout(function(){ $("img").hide(); },毫秒值);”语句,通过定时器来延迟。

修改方法:1、用css()设置新样式,语法“$(元素).css("min-height","新值")”;2、用attr(),通过设置style属性来添加新样式,语法“$(元素).attr("style","min-height:新值")”。

区别:1、axios是一个异步请求框架,用于封装底层的XMLHttpRequest,而jquery是一个JavaScript库,只是顺便封装了dom操作;2、axios是基于承诺对象的,可以用承诺对象中的方法,而jquery不基于承诺对象。

增加元素的方法:1、用append(),语法“$("body").append(新元素)”,可向body内部的末尾处增加元素;2、用prepend(),语法“$("body").prepend(新元素)”,可向body内部的开始处增加元素。

在jquery中,apply()方法用于改变this指向,使用另一个对象替换当前对象,是应用某一对象的一个方法,语法为“apply(thisobj,[argarray])”;参数argarray表示的是以数组的形式进行传递。

删除方法:1、用empty(),语法“$("div").empty();”,可删除所有子节点和内容;2、用children()和remove(),语法“$("div").children().remove();”,只删除子元素,不删除内容。

去掉方法:1、用“$(selector).removeAttr("readonly")”语句删除readonly属性;2、用“$(selector).attr("readonly",false)”将readonly属性的值设置为false。

on()方法有4个参数:1、第一个参数不可省略,规定要从被选元素添加的一个或多个事件或命名空间;2、第二个参数可省略,规定元素的事件处理程序;3、第三个参数可省略,规定传递到函数的额外数据;4、第四个参数可省略,规定当事件发生时运行的函数。
