I wrote an article before, which is an example of system login in Extjs5MVVM mode. After writing this article, someone raised a question, that is, the login form will pop up every time I click. I thought After the login is implemented, there will no longer be a login form interface. It is precisely because of that problem that this article was produced.
Method 1: Official website---Login experience example: http://docs.sencha.com/extjs/5.0/tutorials/login_app.html Add a login logo, which will be displayed differently depending on whether you are logged in or not. Interface
Method 2: Use window.open to jump to the web page.
Step 1: Download extjs5 http://download.csdn.net/detail/sushengmiyan/7701943
Step 2: Create index.html and app.js, the contents are as follows:
app.js
Ext.application({ name : 'EnterSellSaves', launch : function() { Ext.create('Ext.Panel', { renderTo : Ext.getBody(), width : 200, height : 150, bodyPadding : 5, title : 'Hello World', html : 'Hello <b>World</b>...' }); }});index.html
<title>欢迎来到 Ext JS!</title> <link rel="stylesheet" type="text/css" href="ext5/build/packages/ext-theme-neptune/build/resources/ext-theme-neptune-all.css"> <script type="text/javascript" src="ext5/build/ext-all.js"></script> <script type="text/javascript" src="ext5/build/packages/ext-theme-neptune/build/ext-theme-neptune.js"></script> <script type="text/javascript" src="app.js"></script>
In the login interface, add a function to the login button
onclick="login()"
The function is implemented as follows:
<script type="text/javascript"> function login(){ window.opener = null; window.open('','_self'); window.close(); window.open('index.html','11','location=0,resizable=no,fullscreen=true,titlebar=no,status=no,toolbar=no,menubar=no,left=0,top=0'); }</script>
In this way, you can open index, html
For logical judgment, you can change it to jsp or ASP.
In this method, you can use sencha cmd to generate the application framework, or you can manually introduce the js file yourself. It feels pretty good.
Final effect---login page
After login jump
After the page jumps, the URL is also completed.

The function of HTML is to define the structure and content of a web page, and its purpose is to provide a standardized way to display information. 1) HTML organizes various parts of the web page through tags and attributes, such as titles and paragraphs. 2) It supports the separation of content and performance and improves maintenance efficiency. 3) HTML is extensible, allowing custom tags to enhance SEO.

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

The future of HTML is full of infinite possibilities. 1) New features and standards will include more semantic tags and the popularity of WebComponents. 2) The web design trend will continue to develop towards responsive and accessible design. 3) Performance optimization will improve the user experience through responsive image loading and lazy loading technologies.

The roles of HTML, CSS and JavaScript in web development are: HTML is responsible for content structure, CSS is responsible for style, and JavaScript is responsible for dynamic behavior. 1. HTML defines the web page structure and content through tags to ensure semantics. 2. CSS controls the web page style through selectors and attributes to make it beautiful and easy to read. 3. JavaScript controls web page behavior through scripts to achieve dynamic and interactive functions.
