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]);

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

and then describe, and define or directly describe these three methods. For example:Struct BS{Int A: 8;Int B: 2;Int C: 6;} Data;It indicates that data is a BS variable, which occupies two bytes in total. Where a occupies 8 places, B occupies 2 places, and C occupies 6 places. The definitions of bit domains are described as follows:1. A single-byte field must be stored in the same byte, and cannot span two bytes. If the remaining space of one byte is

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

Applicationdomain------- A class of as3, or a technology or concept. Using this technology, you can easily call the server-side SWF and use the methods and variables in the SWF.

I am not familiar with how the entire virtual machine runs a SWF and some internal mechanisms. The language can be artificially encapsulated, but the user's freedom to
