Different domains across domains refer to "Protocol +ip+ Ports", and as long as one of them is not the same, cross-domain access is prohibited for security purposes, and browsers are not accessible for cross-domain default. Now many applications of the client and server are separate, so how to enable the client and server in different domains to achieve cross-dom
relationshipsIn. NET, a thread is the operating system construct that the common language runtime uses to execute code. At run time, all managed code is loaded into a domain and run by a specific operating system thread. However, there is no one by one correspondence between the domain and the thread. At any given time, more than one thread can be executed in a single domain, and a particular thread is not confined to a single domain. That is, threads can span domain boundaries and do not creat
Baidu website, for other sites try also not. The reason is that when the browser in the Ajex jump, in order to ensure server security and data security, the browser will prohibit cross-domain AJEX requests. To make an analogy: a page of a website is you write some JS, these JS some Ajax operationIf a user accesses this page, your JS can get some information about the user (cookies, local files, etc.) and then send it back to your server via Ajax. So you can get whatever data you want to get. Th

Today, we have debugged the 4 K (3840x1920) vsync signal (clock at 297 MHz) in the 170 MHz clock domain, and found that the output signal jitter is particularly severe. It was later discovered that this was caused by different clock domains. Signals in the fast clock domain may not be collected when entering the slow clock domain. So I change the high level of a clock to the high level of three clocks, so that the slow clock domain can certainly be co
Many people have talked about highly adaptive IFRAME in the same domain or across small domains and large domains.
I usually try to avoid using IFRAME, but in actual projects, there are a lot of cross-domain IFRAME that is mandatory and mandatory.
This method involves page cooperation and does not support pages that secretly attract others ....
The most widely spread on the Internet is the use of IFRAME int
I believe there are a lot of people who use WORD. Everyone should have this experience: After adjusting the positions of chapters or paragraphs in the document, it is a headache to modify the chapter number or illustration number. For example, section 2.2.3 and Figure 5.3. There are many solutions to this problem on the Internet, such as cross-reference and selective pasting. Most of these methods use the domain (which is the most distinctive of Office). When writing a document, Word will not au
During Development today, you need to call an address from another department. The demo sent is
VaR userinarray = [];
The key is in document. domain = "remote.net"; this allows me to access his page. After modifying the page according to this demo, I click Save. No response is returned. The JS error message "no permission" is displayed ", I checked it online and found it was caused by this domain. At this time, I wanted to use js to change the domain back, but all of them were prompted with an
You can use the XMLHTTP component or IFRAME to obtain data from the same domain. This is simple because there is no cross-origin access permission problem.
However, to access data in different domains, XMLHTTP does not have the permission to obtain data due to browser security settings, and IFRAME does not have the permission to pass the obtained data to the parent window, there seems to be no other solution.

In this article, the cvfloodfill method in opencv is used for statistics of image connection domains. However, in the cvfloodfill method, the number of cvconnectedcomp records cannot return the detailed coordinate position information, I found some materials and allocated space for cvseq, but there is no value for the contour content. It is estimated that the opencv2.00 version is not supported. Assume that there are two ways to obtain the coordinate

This article mainly introduces jquery + thinkphp to implement cross-origin data capturing methods, and analyzes thinkPHP and jQuery ajax to implement cross-origin data capturing operations in combination with examples, for more information about how to use jquery + thinkphp to capture data across domains, see the following example. We will share this with you for your reference. The details are as follows:
Today, we provide a Remote Data Capture func
in the Scala , names are used to represent types, values, methods, and classes, which are called entities. Naming is present in local definitions and declarations, inheritance,import clauses, and package clauses, which can be collectively referred to as bindings. binding has precedence, defined ( Partial or inherited ) has the highest priority, then the explicit Import , followed by a wildcard character Import , and then the package member, which is the lowest priority. There are two different n
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

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.
