When JavaScript checks whether an object is an instance of a class, it is often OBJ instanceof class. For example: Function class1 (){}; Function class2 (){}; Class2.prototype = new class1 (); Function class3 (){}; Class3.prototype = new class2

With the development of Web 2.0, the interaction between the Internet is getting stronger and stronger, but according to Itzik Kotler, head of IT security company radware security operation center. Javascript may become a new hacker attack point.

Javascript is the basis of many things, such as jsp and ajax. If this is not the case, it will be more difficult to learn these things, lay a solid economic foundation for future learning/('V ')/. Javascript is an object-and event-driven and secure

Display time on the title bar:

When creating a project, you must use ajax without refreshing pages. You can give up the idea because you are not very familiar with the pagerhealkaline class. Think of the pages previously written using SQL stored procedures, so I want to use

In intermediate notes, you will learn other important JavaScript content, such as namespaces, closures, object-oriented, context, general JavaScript, and separated code, these are rarely mentioned in books. We are all confused about this. I believe

Summary Recently, I was looking at the JavaScript advanced programming design (the third edition). The object-oriented chapter contains more than 20 pages, and I went back and forth three or five times. Each time I read different results. The first
