(1) Simplify the codeJavaScript defines objects and arrays very simply, and we want to create an object that is generally written like this: Copy Code code as follows: var car = new Object (); Car.colour = ' red '; Car.wheels = 4; Car.hubcaps = ' spinning '; Car.age = 4; The following writing can achieve the same effect: Copy Code code as follows: var car = { Colour: ' Red ', Wheels:4, Hubcaps: ' S

used, call directly on the line.The disadvantage of this approach is obvious: "pollution" of the global variable, can not guarantee that no variable name conflicts with other modules, and module members do not see a direct relationship. Object Notation To solve the above shortcomings, the module can be written as an object, all module members are placed inside this object. var module1 = new Object ({ _count:0, m1:function () { //... }, m2:function () { //...

Two tips for writing CSS code Declare CSS within a single line Let's compare the following two pieces of code: h2 {font-size:18px; border:1px solid blue; color:#000; background-color:#FFF;}h2 {font-size:18px;border:1px solid blue;color:#000;background-color:#FFF;} The second one looks really formatted, but it doesn't help in reading.

To be a good Java programmer, it is essential to have a good code-writing habit. The following is the code written 30 suggestions, I hope to be helpful to everyone.

For all identifiers, all the words contained in it should be close together, and uppercase the first letter of the middle word. For example: If a co

This section is the heart of the program and the most complex placeThe first thing to understand is that generally for a program with an interface, often requires multi-threading. In this program, in addition to the interface thread, the capture needs to create another new thread. Before writing the packet capture function, the first two modules will be returned to the main dialog interface corresponding to the implementation of the class, in SnifferD

Java programmers need a mixture of object-oriented thinking and general imperative programming methods, the perfect combination of both to rely entirely on the level of programmers: Skills (anyone can easily learn to command-style programming) Pattern (Some people use "pattern-pattern", for example, a pattern can be applied anywhere, and can be grouped into a certain pattern) State of mind (first of all, it's much harder to write a good object-oriented program than an imperative program, and

Writing a C program in Linux is not as #!/bin/bash as writing a shell, but in a C program you want to specify the header file (the header file is only input and output, macros, etc., and must be declared first)Write C code to give executable permission to c file (chmod 755 xx.c)Then compile with gcc (similar to shell, Shell is bash xx.sh, and C is GCC xx.c, C's program file name ends with.

integral part var price = Ten.; var price =. 1;Null is a special value, but we have a lot of time to confuse it with undefined. The best way to understand NULL is to use it as a placeholder for an object.And undefined is also a special value, one of the confusing places when it comes to null = = = Undefined The result is actually true. However, these two values are used differently. Variables that are not initialized (typically only declared) have an initial value, that is, undefined, which ind
