How to prevent reloading of web page from cache while using mobile safari browser?

Mobile Safari uses a special caching mechanism Page Cache (here) which basically keeps the current page alive but hibernated when we navigate to another page. This way, it can immediately display the previous page in its latest state when user presses back button. This is useful for navigation and browsing web but for special cases this becomes annoying as you may need to get a fresh copy of t

如何防止在使用移动Safari浏览器时从缓存中重新加载网页?

Mobile Safari使用特殊的缓存机制Page Cache (这里),它基本上保持当前页面处于活动状态,但当我们导航到另一个页面时处于休眠状态。 这样,当用户按下back按钮时,它可以立即以最新状态显示前一页。 这对导航和浏览网页很有用,但是对于特殊情况,这会变得令人讨厌,因为每次用户导航到该页面时都需要获取新的页面副本。 (在我的情况下,我不得不页:登录和主页)。 我完全知道,没有任何东西阻止用户打开同一应用程序

$("form").submit not working on ipad and iphone

I have a simple post form working in all browsers but when it gets to ipad/iphone (I am new in iOS this world by the way) I got a problem. <form action="/Home/Contact" id="contactform" method="post" novalidate="novalidate"> <div class="response"></div> <p> <input class="textfield" data-val="true" data-val-length="The Name must be 50 characte

$(“form”)。提交不工作在iPad和iPhone上

我有一个简单的发布表单,可以在所有浏览器中工作,但当它到达ipad / iphone(顺便说一句,我是iOS新世界),我遇到了一个问题。 <form action="/Home/Contact" id="contactform" method="post" novalidate="novalidate"> <div class="response"></div> <p> <input class="textfield" data-val="true" data-val-length="The Name must be 50 characters or less" data-v

iPad caching AJAX responses despite setting 'No Store'

I have a page which does an AJAX request to get data, which is then modified by the user. When using the iPad, if the user makes a change, then goes away from the page, then comes back - the AJAX requests are not re-run - meaning the old data is loaded (presumably from the iPad's browser cache). My server code is ASP.NET Forms, and I have tried setting no cache with all the settings I can

iPad缓存AJAX响应,尽管设置了“No Store”

我有一个页面,它执行AJAX请求来获取数据,然后由用户修改。 当使用iPad时,如果用户做出改变,然后离开页面,然后回来 - AJAX请求不会重新运行 - 这意味着旧数据被加载(推测来自iPad的浏览器缓存)。 我的服务器代码是ASP.NET窗体,并且我尝试使用我可以找到的所有设置来设置缓存: Context.Response.Cache.SetNoStore() Context.Response.Cache.SetETag(New Guid().ToString()) Context.Response.Cache.SetExpires(New Da

Ajax post request in ios Safari 6 not work

after upgrade to iOS6.0 release, ajax login page stopped working. It looks like ajax post request made by jquery $.ajax is cached in safari even after adding random querystring parameter and set Cache-control to "no-cache" (these found on net as solution for cache problem). First login attempt works fine, but after logout at second login request browser don't get any response body

ios Safari 6中的Ajax post请求无效

升级到iOS6.0版本后,ajax登录页面停止工作。 它看起来像jquery $ .ajax发出的ajax发布请求,即使在添加随机查询字符串参数并将Cache-control设置为“no-cache”(这些发现在网络上作为缓存问题的解决方案)之后,它也会缓存在safari中。 首次登录尝试正常工作,但在第二次登录请求浏览器注销后,不会从服务器获取任何响应主体。 只有标题。 IOS 6 GM和5版本以及所有桌面浏览器也一样。 有任何想法吗? 我刚刚阅读了这篇

Disabling JIT in Safari 6 to workaround severe Javascript JIT bugs

We found a severe problem with the interpretation of our Javascript code that only occurs on iOS 5/Safari 6 (then current iPad release) that we think is due to critical bug in the Just in Time JS compiler in Safari. (See updates below for more affected versions and versions that seem to now contain a fix). We originally found the issue in our online demos of our library: the demos crash more o

在Safari 6中禁用JIT以解决严重的Javascript JIT错误

我们发现一个严重的问题,那就是我们的Javascript代码的解释只发生在iOS 5 / Safari 6上(当时的iPad版本),我们认为这是由于Safari中的Just in Time JS编译器中的严重错误造成的。 (请参阅下面的更新 ,了解更多受影响的版本和似乎现在包含修补程序的版本)。 我们最初在我们的图书馆的在线演示中发现了这个问题:演示程序或多或少会随机发生崩溃,但这只是第二次(或者甚至更晚)才会执行相同的代码。 也就是说,如果您

Mobile Safari disables ajax function in iOS 5

I have a mobile app running on jQuery Mobile/PhoneGap, and in iOS 5-only my ajax callback stops firing after a while. I'm using jQuery's $.ajax function, and here are some of the error messages I've got: textStatus = parsererror errorThrown = undefined was not called In the second error above 'undefined' is my callback function. My question is, does Mobile Safari disab

Mobile Safari禁用iOS 5中的ajax功能

我有一个在jQuery Mobile / PhoneGap上运行的移动应用程序,并且在iOS 5中 - 只有我的ajax回调在一段时间后停止触发。 我正在使用jQuery的$.ajax函数,以下是我得到的一些错误消息: textStatus = parsererror 没有调用errorThrown = undefined 在上面的第二个错误'undefined'是我的回调函数。 我的问题是,如果太多的错误被抛出,Mobile Safari会在一段时间后禁用函数吗? 我的猜测是,当移动设备的连接速度

How do I return the response from an asynchronous call?

I have a function foo which makes an Ajax request. How can I return the response from foo ? I tried returning the value from the success callback as well as assigning the response to a local variable inside the function and returning that one, but none of those ways actually return the response. function foo() { var result; $.ajax({ url: '...', success: function(respo

如何返回来自异步调用的响应?

我有一个函数foo ,它发出一个Ajax请求。 我怎样才能返回foo的回应? 我尝试从success回调中返回值,并将响应分配给函数内的局部变量并返回该变量,但这些方法实际上都没有返回响应。 function foo() { var result; $.ajax({ url: '...', success: function(response) { result = response; // return response; // <- I tried that one as well } });

How can I get jQuery to perform a synchronous, rather than asynchronous, Ajax request?

I have a JavaScript widget which provides standard extension points. One of them is the beforecreate function. It should return false to prevent an item from being created. I've added an Ajax call into this function using jQuery: beforecreate: function (node, targetNode, type, to) { jQuery.get('http://example.com/catalog/create/' + targetNode.id + '?name=' + encode(to.inp[0].value),

我如何让jQuery执行同步而非异步的Ajax请求?

我有一个提供标准扩展点的JavaScript小部件。 其中之一是beforecreate函数。 它应该返回false以防止创建项目。 我已经使用jQuery将Ajax调用添加到此函数中: beforecreate: function (node, targetNode, type, to) { jQuery.get('http://example.com/catalog/create/' + targetNode.id + '?name=' + encode(to.inp[0].value), function (result) { if (result.isOk == false) alert(result.message); })

How to make a function wait until a callback has been called using node.js

I have a simplified function that looks like this: function(query) { myApi.exec('SomeCommand', function(response) { return response; }); } Basically i want it to call myApi.exec , and return the response that is given in the callback lambda. However, the above code doesn't work and simply returns immediately. Just for a very hackish attempt, i tried the below which didn't wor

如何使一个函数等待,直到使用node.js调用回调

我有一个简化的函数,看起来像这样: function(query) { myApi.exec('SomeCommand', function(response) { return response; }); } 基本上我希望它调用myApi.exec ,并返回回调lambda中给出的响应。 但是,上面的代码不起作用,并立即返回。 只是为了一个非常冒险的尝试,我尝试了下面哪个方法不起作用,但至少你明白了我想要达到的目标: function(query) { var r; myApi.exec('SomeCommand', function(respon

Getting authorized access error from Spotify with spotify
