, object several. Through the object, the array 2 kinds of structure can be combined into a complex data structure.JSONThe JSON(JAvaScript Object Notation) is a lightweight data exchange language designed by the Douglas Kest Rockwell Ford, It is text-based and easy for people to read.Although JSON is a subset of JavaScript, JSON is a language-independent text format and uses some of the same habits as the C language family.The JSON format is a subset

OverviewPrimm algorithm (prim algorithm), an algorithm in graph theory, can search for the smallest spanning tree in weighted connected graphs. This means that the subset of edges searched by this algorithm includes not only all the vertices in the connected graph ( English :Vertex (graph theory)), but also the sum of the weights of all the edges is minimal. The algorithm was discovered in 1930 by t

About this article This article mainly summarizes some of the problems that have been encountered in transmitting JSON data since the site was written and the solutions currently adopted. The website database uses MongoDB, the back end is Python, the front end uses "The half separates" the form the riot.js, the so-called half separates, is said that the first page data is renders directly to the HTML through the server side template engine, thus avoids the homepage two times loading question, b

ignore the property value entirely, or even use the default value. These three types were #required, #IMPLIED, #FIXED加以指定 by three keywords. 10.4.1 #REQUIRED Sometimes it's not easy to choose an appropriate default property value. For example, when you create a DTD for your intranet, you may require that all documents have at least one blank email= elharo@metalab.unc.edu extension= "3459"/> Suppose you want to enforce the identity of the person who posted the document on the internal

" (Doric, a column of ancient Greece) and "Gothic" (Gothic). When the Japanese name sans Serif, they are called Gothic fonts. It is generally accepted that in traditional text printing, the lining has a better readability (compared to sans-serif), especially in large passages, where the line increases the visual reference to the letter when reading. Sans serif are often used in headings, shorter text passages, or some entertainment. Compared to serious lines, no liner gives a relaxed feeling of

Baidu Open the Internet, people can see a striking sign "Baidu", Baidu's search engine to become a quick and convenient tool, as long as a click on key words, people want to know the content of things on the rushes. Therefore, the number of clicks Baidu more than 30 million times a day, the number of Web browsing has ranked 17th in the world, Chinese search volume is also more than 5 of the total number of domestic major sites, and the search does not spend money, attracted a lot of netizens, pe

university's Gigabit Optical Ethernet Research Center (TOEC) to develop the technologies necessary for the next generation of Ethernet, according to the US physicist organization network October 21. Compared with today's most advanced networks, the next generation of Ethernet data transmission speed 1000 times times faster, and more efficient. The researchers hope to develop a 1 Gigabit Ethernet (1000G per second transmission) in 2015 and transmit data through fiber optics, with the ultimate go
