Can't store data fetched with jQuery JSONP

阅读更多关于 Can't store data fetched with jQuery JSONP

I'm trying to fetch a bunch of photo data from Flickr via a jQuery AJAX call using JSONP, but I don't want to use the data right away. Instead, I'd like to preserve it for use later. In a complicated case, I'd like to let users perform different queries on the prefetched data. In a simpler case, I'd like to just load the next n images each time the user clicks a button. Right now, I'm testing just the most basic functionality below, which is adapted from the best answer to this question: JQuery - Storing ajax response into global variable However, the retrieved JSON data is not getting stored

In the console it's giving me the error "Uncaught SyntaxError: Unexpected token : ", but if I access direct SoundCloud URL in my browser then it's giving valid JSON. Earlier this code was working fine and today this issue started. <html> <head> <script src="https://api.soundcloud.com/resolve.json?url=https://api.soundcloud.com/tracks/251912676/?secret_token=s-EkyTy&client_id=08f79801a998c381762ec5b15e4914d5"></script> </head> <body> <h2>hellooo</h2> </body> </html> Update: Below is the actual code for which I am asking the question, above html I just created for example.

I'm trying to learn AngularJS by making a simple web app using the Twitch API ( https://github.com/justintv/Twitch-API ) but I'm having trouble performing a GET request since it's a cross-domain request. This is what I have tried angular.module('streamPlaylisterAppServices', []).factory('twitchService', ['$http', function($http) { return function(usercode){ console.log("usercode inside service is: " + usercode) var authHeader = 'OAuth' + usercode; return $http({ method: 'GET', url: ' https://api.twitch.tv/kraken', cache: false, headers:{ 'Accept': 'application/vnd.twitchtv.v3+json',

Why does a single Ajax call work fine, but consecutive Ajax calls fail?

阅读更多关于 Why does a single Ajax call work fine, but consecutive Ajax calls fail?

问题 Setup: I have a Datatable, whose each row is clickable. When a row is clicked, an ajax call is made which returns some data. Sometimes the ajax call takes a little time, depending on the amount of data being returned. It is all working fine. Problem: The problem occurs when the rows are clicked quickly, one after the other. In short, before the previous ajax call returns, if the row is clicked (i.e. a new ajax call is made), I get an error. Uncaught TypeError: Property 'callback' of object

Please explain JSONP in jQuery

阅读更多关于 Please explain JSONP in jQuery

I can't understand the doc of the jQuery.ajax, specifically two options: jsonp and jsonpCallback , so can somebody be so pleasant to explain? What I do understand is that jsonp is a name of a GET parameter which server expects (usually 'callback') and jsonpCallback is a name of a function to wrap a response. Seems simple. But the explanation at the jQuery.ajax doc makes this a bit complicated. I would like to cite the complete text for jsonp option here and mark with bold what is obscure to me: jsonp Override the callback function name in a jsonp request. This value will be used instead of

But the response argument of this function is always undefined. In the success function however, I

什么是正确的JSON内容类型？

阅读更多关于什么是正确的JSON内容类型？

我一直在弄乱 JSON 一段时间，只是将其作为文本推出，并没有伤害任何人（据我所知），但是我想正确地做事。我见过这么多的所谓的“标准”为JSON内容类型： application/json application/x-javascript text/javascript text/x-javascript text/x-json 但是哪一个是正确的，还是最好的？我发现在它们之间存在安全性和浏览器支持问题。我知道有一个类似的问题，如果REST API返回JSON，则为哪种MIME类型？，但我想要一个更有针对性的答案。 #1楼 JSON的正确内容类型是 application/json 除非您使用 JSONP ，也称为JSON与Padding，它实际上是JavaScript，因此正确的内容类型将是 application/javascript 。 #2楼毫无疑问， application/json 是JSON响应的最佳 MIME 类型。但是由于一些压缩问题，我有一些必须使用 application/x-javascript 经验。我的托管环境是与 GoDaddy 共享的托管。它们不允许我更改服务器配置。我已将以下代码添加到我的 web.config 文件中以压缩响应。 <httpCompression> <scheme name="gzip" dll="

阅读更多关于 JSONP To Acquire JSON From HTTPS Protocol with JQuery

问题 I'm trying to acquire a JSON which is being sent from an https secure site, The client was hoping not to use any Server-side languages (the whole thing in Javascript) I've read that I must use JSONP in order to load a JSON from a secure site, when using the .ajax function from Jquery. My first question would be what format do I need to set this JSONP as? Right now my code looks like this: html =new Object(); html = $.ajax({ url: "https://my-secure.net", async: false, dataType: 'jsonp' })
