Issues with jQuery, ajax, and jsonp

问题 I am using jsonp and ajax to access a web service on another server. Here's the jQuery: $.ajax({ type: 'GET', url: wsurl + 'callback=?', dataType: 'jsonp', crossDomain: true, error: function(data) { console.log('error', data); }, success: function(data) { console.log('success', data); }, complete: function() { console.log('done'); } }); The issue is that the error callback is being called. It gives me this wonderfully helpful information: { readyState: 4, status: 200, statusText: "success" }

Scope of the jquery ajax success callback?

if I have function AjaxRequest(){ var testvar = 0; for(i=0;i<d.length;i++){ $.ajax({ success: function(a){ testvar++; } }); } } Will testvar increase on success? Yes; the variable is captured by the function's closure. Closures keep variables alive so that nested functions can still use them later. Note that the success callbacks only run some time after the rest of your code finishes (AJAX is asynchronous). Yes, it will. It's similar to this: function() { var self = this; this.a = function(){ self.something; } } 来源: https://stackoverflow.com/questions/7326933/scope-of-the-jquery-ajax-success

How to make cross domain ajax call using jQuery JSONP

不羁的心 提交于 2019-12-07 02:59:26
What should I Change the below code to load XML cross domain using jsonp.. $.ajax({ type: "GET", url: "http://www.w3schools.com/xml/note.xml", dataType: "xml", success: function(xml) { alert('Hi'); } }); Hope my problem is resolved. As far as I know you can't (directly) load XML data using JSONP. Cross-site AJAX with JSONP relies on wrapping the required object inside a Javascript function call that's executed inside a dynamically created <script> tag, and there's no mechanism for doing that with XML. Even JSONP requires that the remote server perform the JSON wrapping - a CGI script outputing

问题 I want to return data as JSONP response in Flask . The data comes from a Pandas dataframe and I can return it as JSON with the following line: json_data = dataframe.to_json(orient='values') return json_data Works fine and I get the data, which looks like this: [[1487310600000,1038,1042,1038,1038,-2.243,6.8933],[1487310900000,1042,1042,1038,1038,-1.3626,4.3058],[1487311200000,1042,1042,1038,1038,-1.4631,17.8684]] But I need it as JSONP , so I use the following code: from flask_jsonpify import

Can't get the JSONP working with WCF Data Services

陌路散爱 提交于 2019-12-06 22:25:47
问题 It seems from all that I read and watched, exposing JSON from a WCF Data Service should be as easy as adding the JSONPSupportBehavior attribute to the service class. The problem is that VS2010 doesn't recognize the JSONPSupportBehavior attribute. Is there a reference I am missing? It seems like from all the articles, it was supported out of the box. 回答1: WCF Data Services supports JSON out of the box, no need to add attributes or anything.

【HAVENT原创】superagentCallback*** is not defined

在使用 superagent-jsonp 跨域调用过程中,直接报错:Uncaught ReferenceError: superagentCallback*** is not defined 根本原因是callback已经被浏览器回收了,通过设置timeout时间该问题可以解决 .use(jsonp({timeout: 10000})) 调用示例代码如下: import request from 'superagent' import jsonp from 'superagent-jsonp' const state = { body: {} }; const mutations = { getMovies (state, response) { switch (response.tag) { case 'hotMovies': state.body = response; break; default: state.body = response; } } }; const actions = { getMovies ({ commit }, params) { request .get('https://api.douban.com/v2/movie/in_theaters?count=8') .accept('json') .use(jsonp({timeout: 10000

一、self var root = (typeof self == 'object' && self.self === self && self) || (typeof global == 'object' && global.global === global && global); 现代web之前的window.self和self 对于web页面,在默认状况下,下面4个写法都是等同的: window === self // true window.window === window.self // true window.self === self // true window.window === self // true 其实真实情况还就是这样,并没有需要self出场的理由,唯一可能有作用的就是更语义地判断当前页面是否作为iframe嵌入了,直接: parent === self // true表示作为iframe嵌入,false则表示被iframe嵌入了 在HTML5一些新特性出来之前,全局的self就是个没什么实用价值的半吊子。但是,随着HTML5一些新特性的到来,self开始慢慢登上正式的舞台,最常见的就是用在Service Workers或者Web Workers中。 无论是出来有段时间的Web Workers或者说是新晋宠儿Service Workers

Security Issues with JSONP in jQuery

淺唱寂寞╮ 提交于 2019-12-06 15:53:58
I am writing an app right now that uses jQuery and JSONP to get JSON from 3rd party servers. The main idea behind my app is that it is a Front End with only GUI logic and 3rd party servers can be written by anyone to use the Front End. I have no idea what security issues could arise from this but I definitely see it as a potential issue. What are some steps I can take to make sure that a 3rd party server doesn't completely crash my site that will be running the GUI? JSONP means that you execute third-party javascript which should return a Javascript object. The script you load with JSONP can
