This article mainly introduces the method of clearing the browser cache in angularJs. The editor thinks it is quite good. Now I will share it with you and give it as a reference. Let’s follow the editor and take a look
Caching
A cache is a component that can store data transparently so that it can serve requests faster in the future. . Obtaining resources repeatedly may cause data duplication and consume time. Therefore, caching is suitable for some data with little variability. The more requests the cache can serve, the more the overall system performance can be improved.
Browser cache, sometimes we need it, because it can improve website performance and browser speed, and improve website performance. But sometimes we have to clear the cache, because the cache may cause problems and some erroneous data may appear. For example, stock websites are updated in real time. Such websites do not need to be cached. Some websites are rarely updated, so it is better to have cache.
The following is the traditional method of clearing the browser
meta method
//不缓存 <META HTTP-EQUIV="pragma" CONTENT="no-cache"> <META HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate"> <META HTTP-EQUIV="expires" CONTENT="0">
Clear the temporary cache of the form
<body onLoad="javascript:document.yourFormName.reset()">
ajax clear cache
$.ajax({
url:'www.haorooms.com',
dataType:'json',
data:{},
cache:false,
ifModified :true ,
success:function(response){
//操作
}
async:false
});Use random numbers. Random numbers are also a very good way to avoid caching!
Add "?ran=" Math.random(); //Of course the parameter ran here can be chosen arbitrarily
Use random time, the same as random number.
Add "?timestamp=" new Date().getTime(); after the URL parameters
Use php backend to clean up
Add header("Cache-Control: no-cache, must-revalidate"); and so on on the server side (such as in php)
The following is an introduction to the method of clearing the browser in the angularJs project. Of course, the above traditional method is It is also applicable, but for angularJs, the following items need to be added:
1. Clear the template cache
.run(function($rootScope, $templateCache) {
$rootScope.$on('$routeChangeStart', function(event, next, current) {
if (typeof(current) !== 'undefined'){
$templateCache.remove(current.templateUrl);
}
});
});2. Add random parameters to html
.state("content", {
url: "/",
views:{
"bodyInfo":{templateUrl: 'tpls/bodyInfo.html?'+ +new Date(),
controller:'bodyInfoCtrl'},
"header":{templateUrl: 'tpls/header.html?'+ +new Date(),
controller:'headerCtrl'
},
"footer":{templateUrl: 'tpls/footer.html?'+ +new Date(),
controller:'footerCtrl'
}
}
})<link rel="stylesheet" href="stylesheets/main.css?version=1.0.3" rel="external nofollow" >
3. Clear the route cache
.config(['$stateProvider', '$urlRouterProvider','$locationProvider','$httpProvider',function($stateProvider, $urlRouterProvider,$locationProvider,$httpProvider) {
// $urlRouterProvider.when("", "/home");
$urlRouterProvider.otherwise('/');
if (!$httpProvider.defaults.headers.get) {
$httpProvider.defaults.headers.get = {};
}
$httpProvider.defaults.headers.common["X-Requested-With"] = 'XMLHttpRequest';
$httpProvider.defaults.headers.get['Cache-Control'] = 'no-cache';
$httpProvider.defaults.headers.get['Pragma'] = 'no-cache';Okay...that’s all
If there are other methods, please give me some advice !
The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.

JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AMDifferent 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.
Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AMJavaScript'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: Exploring the Versatility of a Web LanguageApr 11, 2025 am 12:01 AMJavaScript 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.
The Evolution of JavaScript: Current Trends and Future ProspectsApr 10, 2025 am 09:33 AMThe latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.
Demystifying JavaScript: What It Does and Why It MattersApr 09, 2025 am 12:07 AMJavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.
Is Python or JavaScript better?Apr 06, 2025 am 12:14 AMPython is more suitable for data science and machine learning, while JavaScript is more suitable for front-end and full-stack development. 1. Python is known for its concise syntax and rich library ecosystem, and is suitable for data analysis and web development. 2. JavaScript is the core of front-end development. Node.js supports server-side programming and is suitable for full-stack development.
