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. Epiphany ......Scripts that reference

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

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

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 ...

. 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
