The Style property is an object and can only return inline styles.When you need to reference a CSS property with a minus sign in the middle, the DOM asks for the hump naming method, that is, the CSS property font-family becomes the DOM attribute fontFamliy:element.style.fontFamilyRegardless of the number of hyphens in the CSS style attribute's name, the DOM is all represented by the Hump naming method, which is the CSS property backg-color corresponding to the DOM attribute backgroundcolor.CSS3

content "Hello world" is created.InsertBefore: Insert a new element in front of an existing element, when calling this method, you must know three things: 1, new element: The element you want to insert (newelement) 2, Target element: Before which element (targetelement) you want to insert this new element 3, parent element: The parent element of the target element (parentelement) Syntax: Patentelement.insertbefore (newelement,targetelement) We don't have to figure out what the parent element is

to the value of the attribute node. After making changes to the document through SetAttribute, you will still see the value of the property before the change through the browser's view source option to view the document's source code, that is, the changes made by setattribute are not reflected in the source code of the document itself. This "duplicity" phenomenon stems from the DOM's working mode: loading the static content of the document, and then dynamically refreshing, dynamic refresh does

　　　　　　　　　　　　　　 numeric operation built-in function functions nbsp; function ABS (num) Returns the absolute value of num Coerce (NUM1, num2) The Converts NUM1 and num2 to the same type and then returns as a tuple.

(finalizer chaining)" is not automatically executed. If the class (not object) has an finalization method, and the subclass overrides the finalization method, the child class's finalization method must call the superclass's finalization method manually. The subclass is terminated in a try block, and the end method of the superclass is called in the corresponding finally block. Guarantees that the superclass's finalization method will be executed even if the subclass's finalization process throw

way to impose constraints on multiple parameters is to check all the parameters that a constraint must hold with multiple setter methods. Once an invalid argument is passed, the constraint fails immediately, rather than waiting for the build method to be called. The slight advantage of builder compared to constructors is that builder can have multiple mutable parameters. Constructors, like methods, can have only one mutable parameter.The traditional abstract factory implementation in Java is a

At this time, we need to write different CSS for different browsers, so that it can be compatible with different browsers, can also be in different browsers to get the desired page effect. The process of writing different CSS code for different browsers is called C

the location of the label If the page requires a lot of JavaScript code, this will undoubtedly cause the browser to have a noticeable delay in rendering the page, while the browser window in the delay period will be blank. To avoid this problem, modern WEB applications typically place all JavaScript references behind the page content in the DOCTYPE HTML>HTML>Head>title>Example HTML Pagetitle>Head>Body>here to put the content -Scripttype= "Text/javascript"src= "Example1.js">Script>Scripttype= "
