Let's review the composition of the domain name address:http://www. Google:8080/script/jquery.js/HTTP (Protocol number)www (sub-domain)Google (primary domain)8080 (port number)Script/jquery.js (requested address)* When any of the protocols, subdomains, primary domain names, or port numbers are different, the "domain" is counted.* Different domains request resources from each other, called "cross-domain".For example: http://www.abc.com/index.html reque

HTML elements that can link resources from different sources (can be implemented across domains):IMG, script, CSS, video, audio, object, embed, applets, @font-face, frame, IFRAME, etc.(1) (2) tag embedded cross-domain script. Syntax error messages can only be captured in the same-origin script. JSONP also used.(3) HTML elements that can embed resources across domains

The following error is reported when invoking a WCF service across domains using jquery1 $.ajax ({2URL: ' Http://localhost:28207/Service1.svc/GetData ',3Method: ' Get ',4DataType: ' JSON ', 5 data: {value:val},6Successfunction(data) {7$ ("label"). Text ("Success:" +data);8 },9Errorfunction(err) {Ten$ ("label"). Text ("Error:" +err); One } A});Previously thought that cross-domain requests can be as long as the caller makes modi

Using jsonp to call Baidu js across domains to implement smart prompts in the search box, jsonpjs Search is often used in projects, especially for navigation websites. It is unrealistic to search keywords by yourself. Directly calling Baidu is the best choice.The jsonp method of jquery. ajax can be used to call Baidu's js and obtain the return value. Of course, $. getScript can also call js across domains.

Normally, documents on different pages is able to communicate between all other only if their domains, protocols and Por TS match up. HTML 5 specification comes window.postMessage with, which provides cross-domain communication between scripts.Syntaxwindow.postMessage(message, targetOrigin, [transfer]); Message Messages can nested objects and arrays, can contain JavaScript values (strings, numbers, Dates, etc), and can conta

Recently in the project need to use Axios, so it is bad to fill in the Axios what the hell. The more it is Vue-resource alternative, the official website also said, after all with Axios,Vue-resource is not being maintained. So how to use this Axios, Internet search a lot of, basically is the same, I do not know whether the authors have been tested in the local. At least I do not follow the online approach, always can not succeed. After a few days of struggle, I finally made it clear, in order no

Cookie IntroductionFirst, we have a simple introduction to cookies that explain how to use ASP to maintain cookies.A cookie is a small file stored on a client computer, which means that whenever a user accesses your site, you can secretly place a file containing information about it on its hard disk. This file can contain almost any information you intend to set up, including user information, site status, and so on. In this case, there is a potential danger: this information is likely to be rea

When a form file form is submitted across domains, the return result of the remote server cannot be obtained, and the form submission code is as follows:form.submit ({ URL:'http://{remoteurl}/hgisserver/wrds/file', 'Reading your file ... ' , ' POST ' , success:function (FP, O) {console.log (o); }, failure:function (form, action) { Console.lo g (action);} });The error is as follows:" {success:false,message:"http://loc

. Know this principle, our problem also has a brow, that is to use cookies to save SessionID, then we can cheat on the cooikes. We all know that Cooikes records are based on domains (for example: http://www.jb51.net/), which is also required by various browsers. If you do not do this, security will be problematic. All we have to do is to specify the parent domain of the cookie, without specifying the domain, so that the cookies can cross the subdomai

Several ways to request resources across domains, as follows: 1. What is cross-domain 2.JSONP 3.proxy Agent 4.cors 5.xdr Because the browser homology policy, usually send the request URL of the protocol, domain name, port between any one and the current page address is different from the cross domain. The following table can be viewed in detail JSONP This is mainly done by dynamically inserting a script tag. The browser does not have a homol

Company work server is GlassFish, but there is no need for multiple domains. The thing is that you want to configure a domain to do a variety of technical testing. Originally wanted to copy a copy of GlassFish, but it turns out that there are multiple glassfish on a machine that can have a variety of port conflict problems. Later thought of GlassFish not can configure multiple domain, hurriedly go online looking for information. In fact, configuring m

needs to be returned to the client. Then, a function is generated in JavaScript syntax, the function name is the value (success_jsonpcallback) of the parameter passed up (Jsoncallback). Finally, the JSON data is placed into function directly in the form of a parameter, which generates a document of JS syntax and returns it to the client.The client browser, parsing the script tag, and returning the server-side data as an argument,Passed into the client's predefined callback function (as in the

to be passed through the Get method. However, the data receiver is required to add the appropriate receive processing script. Through the Get method can generally achieve some simple data transfer, if you want to implement dynamic cross frame modify page elements or some complex, as the above method is simpler. The code is as follows Copy Code Passing data across domains using cookies or sessionsSet the cookie

Introduction to bit domains in C LanguageWhen storing some information, it does not need to occupy a full byte, but only needs to occupy a few or one binary bit. For example, when storing a switch value, there are only two States: 0 and 1. Use one binary digit.To save storage space and simplify processing, the C language also provides a data structure called a bit field or bit segment. The bit field divides the binary character in a byte into several

. Parameters: The data returned by the server and processed according to the DataType parameter; A string describing the state. This is an Ajax event. Traditional Type: Boolean If you want to serialize the data in a traditional way, set it to true. Please refer to the Jquery.param method under the Tools category. Timeout Type: Number Sets the request time-out (in milliseconds). This setting overrides
