Ajax method to get web pages added to div

Ajax method to get the web page added to the div

1: Use DOM to get the ID of the div, and then clear the content of the DIV ( If you need to add the content inside, do not clear it); it should be noted that it is best to use "empty()" to clear it;

2: Set async to true, otherwise there will be another warning error, this The error prevents your content from being displayed; the following is the warning error

3: Just add HTML.

The specific code is as follows:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>测试</title>
</head>
<body>
  <div id="tset">
    <a href="http://www.baidu.com">百度</a>
  </div>
  <button id="btn">测试</button>
</body>
<script src="../../Js/jquery-3.4.1.js">
 
</script><script src="../../Js/layer-v3.1.1/layer/layer.js"></script>
<script>
    $(function(){
        $("#btn").click(function(){
            $.ajax({
                url:&#39;../../Html/JQueryDome/弹框.html&#39;,
                dataType:&#39;html&#39;,
                type:&#39;get&#39;,
                async:true,
                success:function(data){
                    console.log(data);
                   $("#tset").html(data)
                },error:function(){
 
                }
            })
        })
    })
</script>
</html>

Finally, let’s summarize the method of clearing the contents of Div

empty()  情况选择器里面的内容  
语法 $(“选择器”).empty() 
remove()  删除后再恢复事件不在
语法 $(“选择器”).remove()
detach()   删除后再恢复事件在
语法 $(“选择器”).detach()

By the way, let’s give the rest as well. :

Package

wrap()      每一个外面都添加一个新的元素
语法 $(“选择器”).wrap(“<元素名称>”)
wrapAll()    同一包裹一个元素
语法 $(“选择器”).wrap(“<元素名称>”)
wrapInner()  在里面添加一个新的元素
语法 $(“选择器”).wrap(“<元素名称>”)
unwrap()    去掉包裹
语法 $(“选择器”).wrap(“<元素名称>”)

External insert

after()           在后面插      语法：  $(“选择器”).after(“<元素名称>”)
insertAfter()      在后面插      语法：  $(“选择器”).insertAfter(“<元素名称>”)
before           在后面插      语法：  $(“选择器”).before(“<元素名称>”)
insertBefore()     在后面插      语法：  $(“选择器”).insertBefore(“<元素名称>”)

Internal insert(in)

append()         在后面插       语法：  $(“选择器”).append(“<元素名称>”)
appendTo()       在后面插       语法：  $(“<元素名称>”).appendTo(“选择器”)
prepend()        在前面插       语法：  $(“选择器”).prepend(“<元素名称>”)  
prependTo()      在前面插       语法：  $(“<元素名称>”).prependTo(“选择器”)

Replace

replaceWith() 语法 $(“选择器”).replaceWith($(“选择器”))
replaceAll    语法 $(“<元素名称>”).replaceAll    (““选择器”

Clone

clone()

Grammar:

1、$(“选择器”).clone().append(“元素名”)
2、$(“选择器”).append($(“元素名”).clone())

By the way, another point is (of course I encountered it in MVC, I’m not sure if there are any), that is, there is internal JS in the obtained web page, such as <script> Here is a function to get the local time </script>. Then when you execute AJAX, the page will not be added to the DIV, and the entire page will be the current time (but the address will not change). Solution: You can delete the JS, or replace the JS with an external JS.

From Websites to Apps: The Diverse Applications of JavaScriptApr 22, 2025 am 12:02 AM

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python vs. JavaScript: Use Cases and Applications ComparedApr 21, 2025 am 12:01 AM

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

The Role of C/C in JavaScript Interpreters and CompilersApr 20, 2025 am 12:01 AM

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AM

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UseApr 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.

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

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.
