What is the difference between these headers? Content-Type: application/javascript Content-Type: application/x-javascript Content-Type: text/javascript Which one is best and why? Please do not say they are identical - if they were identical there would not have been two of them. I know both work - but I would like to know the difference. text/javascript is obsolete, and application/x-javas
这些头文件有什么区别？ Content-Type: application/javascript Content-Type: application/x-javascript Content-Type: text/javascript 哪一个最好，为什么？ 请不要说它们是相同的 - 如果它们是相同的，就不会有两个。 我知道这两个工作 - 但我想知道其中的差异。 text/javascript是过时的，并且application/x-javascript是实验性的（因此是x-前缀）的过渡期，直到application/javascript可以被标准化。 你应该使用a
I have a javascript app that sends ajax POST requests to a certain URL. Response might be a JSON string or it might be a file (as an attachment). I can easily detect Content-Type and Content-Disposition in my ajax call, but once I detect that the response contains a file, how do I offer the client to download it? I've read a number of similar threads here but none of them provide the answe
我有一个JavaScript应用程序，它将ajax POST请求发送到某个URL。 响应可能是JSON字符串，也可能是文件（作为附件）。 我可以在我的ajax调用中轻松检测Content-Type和Content-Disposition，但是一旦我检测到响应包含文件，我该如何提供客户端来下载它？ 我已经阅读了许多类似的主题，但没有一篇提供我正在寻找的答案。 请，请不要发布答案，建议我不应该为此使用ajax，或者我应该重定向浏览器，因为这不是一个选项。 使用纯
I have the following Jquery callback function and I have a litle doubt about it (I don't know very well Jquery): $("form.readXmlForm").submit(function() { // Riferimento all'elemento form che ha scatenato il submit var form = $(this); // Variabile che contiene il riferimento al bottone clickato var button = form.children(":first"); $.ajax({ // Viene eseguita la
我有以下的jquery回调函数，我对它有疑问（我不太清楚Jquery）： $("form.readXmlForm").submit(function() { // Riferimento all'elemento form che ha scatenato il submit var form = $(this); // Variabile che contiene il riferimento al bottone clickato var button = form.children(":first"); $.ajax({ // Viene eseguita la chiamata AJAX type: "POST", // Tipo di richiest
I would like to add a custom header to an AJAX POST request from jQuery. I have tried this: $.ajax({ type: 'POST', url: url, headers: { "My-First-Header":"first value", "My-Second-Header":"second value" } //OR //beforeSend: function(xhr) { // xhr.setRequestHeader("My-First-Header", "first value"); // xhr.setRequestHeader("My-Second-Header", "
我想将自定义标题添加到来自jQuery的AJAX POST请求中。 我试过这个： $.ajax({ type: 'POST', url: url, headers: { "My-First-Header":"first value", "My-Second-Header":"second value" } //OR //beforeSend: function(xhr) { // xhr.setRequestHeader("My-First-Header", "first value"); // xhr.setRequestHeader("My-Second-Header", "second value"); //} })
I want to trigger an ajax request when the user has finished typing in a text box. I don't want it to run the function on every time the user types a letter because that would result in A LOT of ajax requests, however I don't want them to have to hit the enter button either. Is there a way so I can detect when the user has finished typing and then do the ajax request? Using jQuery he
我想在用户输入文本框时触发ajax请求。 我不希望它在每次用户键入一个字母时运行该函数，因为这会导致大量的ajax请求，但是我不希望他们必须点击输入按钮。 有没有办法让我可以检测用户何时完成键入，然后执行ajax请求？ 在这里使用jQuery！ 戴夫 所以，我要猜测完成打字意味着你只停留了一段时间，比如5秒。 因此，考虑到这一点，我们可以在用户释放一个密钥并在按下某个密钥时将其清除，然后启动计时器。 我决定输入
I have a jquery-based single-page webapp. It communicates with a RESTful web service via AJAX calls. I'm trying to accomplish the following: Submit a POST that contains JSON data to a REST url. If the request specifies a JSON response, then JSON is returned. If the request specifies a PDF/XLS/etc response, then a downloadable binary is returned. I have 1 & 2 working now, and th
我有一个基于jQuery的单页web应用程序。 它通过AJAX调用与RESTful Web服务进行通信。 我试图完成以下任务： 将包含JSON数据的POST提交给REST网址。 如果请求指定了JSON响应，则返回JSON。 如果请求指定了PDF / XLS / etc响应，则返回可下载的二进制文件。 我现在有1和2工作，客户端jQuery应用程序通过创建基于JSON数据的DOM元素在网页中显示返回的数据。 我也从Web服务的角度来看＃3，这意味着如果给出正确的JSON参
I've tried to parse the following json response with both the JQuery getJSON and ajax: [{"iId":"1","heading":"Management Services","body":"<h1>Program Overview</h1><h1>January 29, 2009</h1>"}] I've also tried it escaping the "/" characters like this: [{"iId":"1","heading":"Management Services","body":"<h1>Program Overview </h1><h1>Jan
我试着用JQuery getJSON和ajax解析下面的json响应： [{"iId":"1","heading":"Management Services","body":"<h1>Program Overview</h1><h1>January 29, 2009</h1>"}] 我也尝试过逃避这样的“/”字符： [{"iId":"1","heading":"Management Services","body":"<h1>Program Overview </h1><h1>January 29, 2009</h1>"}] 当我使用getJSON时，它不会执行回调。 所以，我试着用JQu
