First, cross-compilingGenerate executable code on another platform on one platform. Why do you have to cross-compile it? In a word: It is the last resort. Sometimes it is because the target platform is not allowed or unable to install the required compiler, but also need some characteristics of the compiler, sometimes because the target platform is resource-poor, unable to run the required compiler, and som

Client-side "Cross-domain access" has been a headache, but with jquery to help, the cross-domain problem will be solved after jQuery-1.2. Due to the Cross-domain problem in the project, I take this opportunity to find out the cross-domain problem, consult the relevant data and own practice, which solves the problem of
1. What is a homology policy
Understanding a Cross-domain must first understand the homology policy. The homology policy is a very important security policy that is implemented on the browser for security reasons.
What is homology:
The URL consists of a protocol, domain name, port, and path, and if the protocol, domain name, and port of the two URLs are the same, they are homologous.
homology policy:
The browser's homology policy restricts "docum

Talk about the portability of C + + today. If you normally use C + + for development, and you are not very clear about the portability of C + +, then I suggest you look at this series. Even if you don't have the need for cross-platform development at the moment, it's helpful to know about portability.C + + Portability This topic is very large, including compilers, operating systems, hardware systems and many other aspects, each has a lot of c

(4) Using native JS to implement POST request:
var xml=new xmlhttprequest ();
Xml.onreadystatechange=function () {
if (xml.readystate==4xml.status==200)
{
var data= Json.parse (Xml.responsetext);
}
else{
alert ("Request Failed");
}
Xml.open ("Post", "url", "true");//url inside for the requested address, True indicates the asynchronous request
Xml.setrequestheader ("Content-type", "application/ X-www-form-urlencoded "); Set Request header
Xml.send (NULL) for POST
Introduction to Ajax
Ajax, "Asynchronous JavaScript and XML" (Asynchronous JavaScript and XML), refers to a web development technology that creates interactive Web applications.
AJAX = Asynchronous JavaScript and XML (a subset of standard generic markup languages).
AJAX is a technique for creating fast-moving web pages.
AJAX enables asynchronous updating of Web pages by making a small amount of data exchange in the background with the server. This means you can update portions of a Web page
Learning Ajax In fact has a very important application, is to perform several other sites of ASP, return the results.
Really use up, found 2 problems, always do Delphi, contact ASP Not many of me, indeed a lot of problems.
First question:
VBS variable passed to JS ... By learning to find very simple ...
First look at my general implementation methods:
The above code means to use AJAX to access an ASP, and return the result.
Did you see that? This is the key:

from:53333775As mentioned in the previous article, because of the browser's homologous policy, so that the AJAX request can only be sent to the same-origin URL, or error. In addition to setting up a server proxy, such as Nginx (the browser requests the same origin server, and then the latter requests the external service), there are three ways to circumvent this limitation:First, JSONPJsonp is a common method for server-to-client cross-origin communic
What is a cross-domain request? The simple understanding of is to make a request to a server file that is not in the same domain name. This is still a practical example to explain it, such as baidu.com to cxyblog.com send a request, the two domain name is different, then this is cross-domain, for security reasons, this is not allowed. Also need to note that different subdomains or the same domain name be
Note: The following code is tested in the version after Firefox 3.5, Chrome 3.0, and Safari 4. The implementation of IE8 is different from other browsing. Cross-domain requests, as the name suggests, are resources in one site to access resources on another different domain name site. This is common, such as loading an external style sheet file with a style tag, loading an external picture via an IMG tag, loading an external script file with a script
What is a cross-domainCross-domain refers to a resource that requests another domain name from a Web page of a domain name. For example, from the Www.baidu.com page to request www.google.com resources. The strict definition of cross-domain is that as long as the protocol, domain name, the port has any difference, it is considered to be a cross-domainThe previous
What is cross domain?
Simply put, for security reasons, JavaScript on the page cannot access data on other servers, or "homology policies." Cross-domain is through some means to circumvent the same-origin policy restrictions, to achieve the effect of communication between different servers.
Specific policy restrictions can be seen in the following table:
