How to clear browser cache in angularJs
A cache is a component that transparently stores data so that future requests can be served faster. 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. In this article, we share with you how to clear the browser cache in angularJs.
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
$.ajax({
url:'www.haorooms.com',
dataType:'json',
data:{},
cache:false,
ifModified :true ,
success:function(response){
//操作
}
async:false
});Use random numbers. Random numbers are also a very good way to avoid caching!
Add "?ran=" + Math.random(); //Of course the parameter ran here can be chosen arbitrarily
Use random time, the same as random number Sample.
Add "?timestamp=" + new Date().getTime(); after the URL parameters
Use php backend to clean up
Add header("Cache-Control: no-cache, must-revalidate"); and so on (such as in php) on the server side
The following is about clearing the browser in the angularJs project Method, of course the above traditional methods are also applicable, but for angularJs, the following items need to be added:
1. Clear the template cache
.run(function($rootScope, $templateCache) {
$rootScope.$on('$routeChangeStart', function(event, next, current) {
if (typeof(current) !== 'undefined'){
$templateCache.remove(current.templateUrl);
}
});
});2. Add random parameters to html
.state("content", {
url: "/",
views:{
"bodyInfo":{templateUrl: 'tpls/bodyInfo.html?'+ +new Date(),
controller:'bodyInfoCtrl'},
"header":{templateUrl: 'tpls/header.html?'+ +new Date(),
controller:'headerCtrl'
},
"footer":{templateUrl: 'tpls/footer.html?'+ +new Date(),
controller:'footerCtrl'
}
}
})<link rel="stylesheet" href="stylesheets/main.css?version=1.0.3" rel="external nofollow" >
3. Clear route cache
.config(['$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';Related recommendations:
