Ajax (also AJAX / ˈ eɪ dʒ æ k s /; short for "asynchronous JavaScript and XML" [1] [2]) is a set of web development techniques that uses various web technologies on the client-side to create asynchronous web applications.
console. log (a || b); // if a is true, return a, otherwise return b console. log (a && b); // if a is false, return a, otherwise return b Programmers who are more familiar with the behavior in C might find this feature surprising, but it allows for a more concise expression of patterns like null coalescing :
The Java driver can also be used with JavaScript (via the Rhino engine). An instance of selenium RC server is needed to launch html test case - which means that the port should be different for each parallel run. [citation needed] However, for Java/PHP test case only one Selenium RC instance needs to be running continuously. [14]
The Java Modeling Language (JML) is a specification language for Java programs, using Hoare style pre-and postconditions and invariants, that follows the design by contract paradigm. Specifications are written as Java annotation comments to the source files, which hence can be compiled with any Java compiler .
In 2000, Jason Hunter, author of "Java Servlet Programming" described a number of "problems" with JavaServer Pages. [21] Nevertheless, he wrote that while JSP may not be the "best solution for the Java Platform" it was the "Java solution that is most like the non-Java solution," by which he meant Microsoft's Active Server Pages.
The value range form is as follows: for i from f by b to t while w do # loop body od; All parts except do and od are optional. The for I part, if present, must come first. The remaining parts (from f, by b, to t, while w) can appear in any order. Iterating over a container is done using this form of loop: for e in c while w do # loop body od;
Use four tags to create the components, define their functions and arguments, and return a value. <cfcomponent>: Defines a CFC <cffunction>: Defines the functions (methods) within a CFC <cfargument>: Defines the arguments (parameters) that a function accepts <cfreturn>: Returns a value or result from a function. CFCs are plain CFML.
With the increased interest in developing "Web 2.0" rich web applications, the complexity of programming directly in Ajax and JavaScript has become so apparent that compiler technology has stepped in, to allow developers to code in high-level languages such as Java, Python and Ruby.
