art of multiprocessor programming

It took a weekFinally, I read "JS + DOM programming art" separately.This is the fourth book on JS in the last one and a half months.Others are "JS completely self-taught manual", "Return of the JS King", and "JS Programming Tutorial".The reason why I went to see this is to read a post on csdn looking forward to JS, which is very recommended. Let's talk about it.

The first chapter:1.DOM: is a set of methods for abstracting and conceptualizing the content of a document, which is an API.2.W3C definition of DOM: An excuse that is independent of the system platform and programming language programs and scripts can dynamically access and modify document content, structure, and style through this interface.3.Ajax: Asynchronous data transmission, H5 4.JavaScript Basic Syntax:Multiline comment "/* * *"　　　　　　　　　　　　　　　　

After reading this book today, I finished the last comprehensive example. To tell the truth to gain a lot, finally understand what the front-h5 specifically doThe more you learn, the more ignorant it seems, this is really a truth. Post-planning:1, CSS + DIV layout In-depth understanding, key combat2, JavaScript advanced programming that book thoroughly understand3, background and front-end data exchangeWhy I like technology, it's weird:-)Javascript-do

value (number), Boolean (Boolean) are scalar (scalar) in this book is just a brief introduction.5. An array array is a set of values represented by a variable, and each value in the collection is an element of the array.The number of array elements is the length of the array, and the element to be added to the array is called padding (populating).Declaration method: var beatles = Array (number); var beatles=[];var beatles = new Array ();padding: array[index]=element; array elements can be of va

JavaScript and DOM, we can completely collect that information and insert it into the document using the SUP element.List of shortcut keysThe AccessKey property can associate an element (such as a link) with a specific key on the keyboard. This is useful for people who can't or don't like using a mouse to browse the Web.In general, in browsers for Windows systems, the use of shortcut keys is to press the ALT key and specific keys at the same time on the keyboard, and in browsers for Mac systems

Read JavaScriptDOM programming art notes. For more information, see. 1. Obtain the next element of the current element. The Code is as follows: Function getNextElement (node ){If (node. nodeType = 1 ){Return node;}If (node. nextSibling ){Return getNextElement (node. nextSibling );}Return null;}; 2. Add the page loading method for js externally introduced The Code is as follows: Function addLoadEvent

This article mainly introduces the JavaScript image library of reading notes in JavaScriptDOM programming Art. if you need it, you can refer to the following two methods to change the src attribute of the image: 1. the setAttribute method is an integral part of "level 1st DOM". it can be used to set any attribute of an element node. 2, element. src = source; this is the method before "level 1st DOM" appear

This article mainly introduces the DOM basis of Reading Notes in JavaScriptDOM programming art. For more information, see DOM DOM: Document Object Model; Node Element Node: DOM atoms are element nodes., , And so on. An element can contain other elements. The only element that is not included in other elements isElement Text node: in XHTML documents, text nodes are always contained in element nodes.

4th: JavaScript Picture LibraryMultiple pictures of the problem, think about doing an example:How event handlers work: Once an event occurs, the corresponding JS code is executed once the element has been added to the event handler function.　The called JS code can return a value that will be passed to the event handler. Generally returns TRUE or FALSE. True event handler function: event occurs false: Event not seenNodetype:1: Element Node 2: Attribute node 3: text nodeNodevalue:element[0].nodeva

GetAttribute SetAttribute Get and Set propertiesGetAttribute Get Properties:Syntax: Object.getattribute (attribute); This method does not belong to the Document object, so it cannot be called with the Document object, but only through the element node object; The setattribute is the same;For example, var paras = document.getelementsbytagname (' P ');Alert (Paras[0].getattribute (' title '))SetAttribute modifying attributes;Object.setattribute (Attribute,value);Example: var shopping = document.g

Pointer programming art (2) pointer and string The pointer variable size is 4 bytes. Let's look at an example: #include It is found that the address distance between two data types is 8, which is exactly the size of double data (the address gap is the size of the Data Type pointed to by the pointer variable), but it is not the size of the pointer type variable, in fact, we can see that this a

JavaScript library for Reading Notes in JavaScript DOM programming art, javascriptdom There are two ways to change the src attribute of an image: 1. The setAttribute method is an integral part of "level 1st DOM". It can be used to set any attribute of an element node. 2, element. src = source; this is the method before "level 1st DOM" appears, and it is valid now. The advantage of "level 1st DOM" is its por

smooth degradation and progressive enhancement principle smooth degeneration: If you use JavaScript scripts correctly, you can allow visitors to navigate your site without the support of JavaScript in their browsers. This is called stationary degradation (graceful degradation), which means that although some functions are not available, But the most basic operation can still be completed smoothly. progressive enhancement: The Web pages that were created in accordance wit
