Small series into the study stage of the BS for a period of time, learning procrastination, need to carefully organize the knowledge before learning. Review the DOM (document ObjectModel) Documentation object model for the knowledge points in JavaScript, for HTML and XML document APIs (application interfaces).is a standard programming interface recommended by the Organization for the processing of extensib

each browser JavaScript code is still the same, for the commonly used features have in fact already has the default standard. so do not worry about browser compatibility issues, not every browser has its own BOM, do not need to learn a set of BOM for each browser, but the individual browser will have new features will be reflected in the BOM.Dom1. The DOM is the abbreviation for the Document Object model,

This article mainly introduces the differences between childNodes and children in JavaScript operations on DOM elements. This article describes the differences between the test code and the running effect. If you need them, refer to DOM elements, children is a sub-Object of the DOM Object type, excluding the TextNode i

Accessing and modifying DOM elements will cause the browser to recalculate the geometric changes of the page. The following describes how to improve the javascript performance. If you need to access DOM elements, you can refer to it at a cost, modifying DOM elements is more expensive because it causes the browser to re

error: The code is as follows Copy Code Myintrostyles.padding-top = ' 10em '; A syntax error has occurred:Horizontal line in JavaScript-is the subtraction operatorAnd there's no such property name Properties can be accessed like arrays, so using this knowledge we can create a function to change the style of any given element: The code is as follows Copy Code function Changestyle (El

This article briefly introduces the nature and operation methods of JavaScript DOM. Although some JavaScript frameworks such as jQuery, Prototype, and MooTools can improve our front-end development efficiency, the browser compatibility is well solved, but we still need to lay a solid foundation for javascript technolog

This code is a simple example. Extract two random images from the five images in the first div and display them to the second div. The specific implementation is as follows, if you are interested, you can randomly add images in the First dom to the second p by referring to javascript.

Writing unobstrusive code means completely separating HTML content: the data comes from the server, and javascript code is used for dynamic and interaction. The advantage of this separation is that different browsers can be fully degraded or upgraded to provide richer interaction for advanced browsers, browsers that do not support advanced features can downgrade the part they support.I.
