文章目录 用hash、history实现单页面 hash history vue-router 三种模式 hash和history的区别 vue-router的实现 其他问题 1、什么是单页应用，原理？ 2、单页面和多页面的区别？ 3、Vue-router有哪些钩子？使用场景？ 4、完整的路由导航解析流程 5、vue-router的三种跳转方式 用hash、history实现单页面 hash hash原理：hash router 有一个明显的标志是url 中带有#， 我们可以通过onhashchange监听url中的hash来进行路由跳转 # 后面的 fragment 发生改变时，页面不会重新请求，其他参数发生变化，都会引起页面的重新请求 Onhashchange事件触发条件： 这是一个HTML 5新增的事件，当#值发生变化时，就会触发这个事件。IE8+、Firefox 3.6+、Chrome 5+、Safari 4.0+支持该事件。 直接更改浏览器地址，在最后面增加或改变#path； 通过改变location.href或locaion.hash的值 通过触发点击带锚点的连接 浏览器前进后退可能导致hash的变化，前提是两个网页地址中的hash值不同（会留下一个历史记录） 它的使用方法有三种： window.onhashchange = func; <body

jquery.history.js VS jquery-hashchange

由 会有一股神秘感。 提交于 2019-12-29 18:43:12
问题 See http://balupton.github.io/jquery-history/demo/ I was attracted with jquery.history.js mean while I found http://benalman.com/code/projects/jquery-hashchange/examples/document_domain/ I think the second one is just based on JQuery. I mean it don't need any additional plugin than jQuery. What is special in jquery.history.js? than hash change?. Which should I use to override my browsers back and forward buttons ? 回答1: EDIT - Late 2013 Another hash library called "sammy.js" is popular as well

问题 How can I write the JavaScript callback code that will be executed on any changes in the URL anchor? For example from http://example.com#a to http://example.com#b 回答1: Google Custom Search Engines use a timer to check the hash against a previous value, whilst the child iframe on a seperate domain updates the parent's location hash to contain the size of the iframe document's body. When the timer catches the change, the parent can resize the iframe to match that of the body so that scrollbars

Disabling hashchange listener when updating hash programatically (jQuery BBQ)

由 怎甘沉沦 提交于 2019-12-23 15:35:26
问题 To prevent a feedback loop when setting the URL hash (#) programmatically (in contrast to manually changing the URL) I want to disable the hashChange listener temporarily. How should I change this code to actually disable the hashchange event when updating the hash using $.bbq.pushState(hash)? (code below doesn't work) hashChangeEnabled : true, bindHashChange : function(){ var that = this; $(window).bind( 'hashchange', function( event ) { if(that.hashChangeEnabled == true){ stateObj = event

Javascript anchor navigation

问题 I am creating a website with the "anchor navigation" like used with facebook and google mail. I have got it working but not fully. When I load the page with something like #contact it won't load it in unless I click the link for it. Also, would there be a better, more efficient way to do what I am doing? I am not the best person with JS programming. JavaScript : $.navigate = function() { // a new link if($anchor != document.location.hash){ // add a preloader $("#content") .empty() .html('<p

问题 Does onHashChange or hashChange work in Safari? I tested it with Safari 4.0.4 on Windows 7 and it doesn't work for me. If it doesn't work, is there any solution to track if the hash has changed? 回答1: In our app we poll to check for changes: $b.hashCheck = setInterval( function(){ if ( window.location.hash !== $b.C.current_hash){ $b.C.current_hash = window.location.hash; //call the on change action here } },$b.C.hashCheckDelay ); $b is the global object we use for our namespace and
