A complex project is often composed of hundreds of elements. How to quickly locate elements is very important for developers. To do this, it is not difficult indeed. In VS, this can be done through the HTML tag navigator. The main problem now is a habit and experience problem for developers. Although I can not say that the experts in this field, but also quite have experience. Here to share with you.
One, the most common two kinds of element localiza
Among many browser products, IE, Firefox, Opera, Safari ........ many brands have different standards. Therefore, you often need to perform different operations based on different browsers or even different versions of the same browser. Therefore, it is very important to know the browser's judgment method. The following lists common judgment methods.1. Determine whether the browser is IEDocument. all? 'Ie': 'others ': the document. all value in IE is 1, and the value in other browsers is 0;
access control modifiers
Scala's access modifiers can add scope parameters. The syntax for the scope is as follows:PRIVATE[X] or protected[x]where x represents a package, a class, or a single instance object that can access this private or protected range until x.
By adding scope parameters to the access modifier, you can control very precisely the scope of the defined type that can be accessed by other types. In particular, package private,package protected, which supports Java language suppor
hierarchies, subclasses can inherit the properties and methods of the parent class. Unlike some other object-oriented programming languages, Java only supports single inheritance. 3. SecuritySecurity can be divided into four levels, namely, language-level security, compile-time security, run-time security, executable code security. Language-level security refers to the data structure of Java as a complete object, which has security over the encapsulated type Compile-time Java language and sem
