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 A

Compression script:The so-called compression script, refers to the script file unnecessary bytes, such as spaces and comments, all deleted, so as to achieve the purpose of "compressed" file. Fortunately, there are many tools that can do it for you. Some refiners will even rewrite some of your code, using shorter variable names to reduce the overall file size. The streamlined code, while not easy to read, can drastically reduce file size. In most case

adept at handling repetitive tasks. It is easy to traverse a long list with a while or for loop.Responding to EventsCSS provides: pseudo-class attributes such as hover allow us to change the style based on the state of the HTML element. The DOM can also respond to changes in the state of an HTML element through events such as onmouseover. So when to use: hover, when to use onmouseover?The simplest answer is to choose the easiest way to achieve it. For example, if you just want the link to chang

False2. Range of valuesDue to memory limitations, ECMAScript cannot save all the values in the world, and the smallest value ECMAScript can represent is saved in Number.min_value, which is 5e-324 in most browsers. The maximum value that can be represented is saved in Number.MAX_VALUE, which is 1.7976931348623157e+308 in most browsers. If the result of a calculation is given a value that is outside the range of JavaScript values, if the value is negative, it is converted to-infinity (negative in

1. A document is a tree of nodes2. Nodes are divided into different types: element nodes, text nodes, attribute nodes, etc.3. Each node is an object, and the atom of the DOM is an element node4.getElementById returns an object that corresponds to a specific element node in the document5.getELementsByTagName and Getelementsbyclassname return an array of objects that correspond to a specific set of ELEMENT nodes in the document, respectively.The 6.typeof operator can tell us whether its operand is

, this usage is not a good habit and is not recommended for everyone to use. Essentially, when you create an associative array, you create an array object's properties. In JavaScript, all variables are actually objects of some kind. For example, a Boolean value is an object of type Boolean. In the above example, you are actually adding the name, year, and living three properties to the lemon array. Ideally, you should not modify the properties of an array object, but you should use a generic obj

=document.getelementbyid (' id name '); Returns the element node, where each element node is an object, so the data type returned is an objectThe tag and class methods can iterate through a set of elements with a for loop4, gets and sets the element's attributes , which belong to the element node objectGets the property name of the attribute getattribute, a parameter that needs to be obtained.Set the property SetAttribute, two parameters, need to modify the property name, the modified value.Note
