scope after it gets the code, and if it does, it will throw an error if it does not. This process concludes that the code first declares the relevant variables in the compiler and then hands them to the engine, and the engine operates on those variables (assignment, etc.).With the above analysis process, let's look at the first code: The reason why the book can be changed into the following code, is because this code will be compiled in the compiler, the process of compiling the code in the sco

The 1th Chapter JS Introduction1.js consists of three parts, ECMAScript, DOM, BOM.The 2nd chapter uses JS in HTML1. Put the The defer property of the 2.Chapter 3rd Basic Concepts1.js Everything is case-sensitive. The first digit of the identifier cannot be a number.Five basic types of 2.js: undefined,null,boolean,number,string. A complex Type: object.3.null is used to assign values to variables that are ready to be saved.The 4.Boolean () function converts the value of any data type to a Boolean

Android5.0 introduced the concept of z-axis, so it has this style, that is, the current comparison of fire material Design.1. Android:elevation sets the height of the component "floating", to be sad too setting this property allows the component to render a 3D effect.2. Android:translationz sets the displacement of the component in the Z-direction (vertical screen orientation).Corresponding Java method: Setelevation (float) Settranslationz (float)Reference: Android l--material design details (vi

) Developers can take advantage of this to allow the function to receive arbitrary parameters and to implement the appropriate functions separately .eg 1 function Doadd () { 2 If (Arguments.length==1 3 alert (Arguments[0]+10 4 }else if 5 alert (AR Guments[0]+arguments[1 6 } 7 } 8 doadd (20 9 doadd (21,10); (5) Arguments objects can be used with named parameters:eg1 functionDoadd (num1,num2) {2 if(arguments.length==1){3AlertNUM1+10);4}Else if(arguments.length==2){5Alertarg

To avoid this situation, modern Web applications typically place JavaScript references behind the page content in the BODY element. eg1 DOCTYPE HTML>2 HTMLLang= "en">3 Head>4 MetaCharSet= "UTF-8">5 title>Testtitle>6 Head>7 Body>8 here to put the content -9 Scripttype= "Text/javascript"src= "Example1.js">Script>Ten Scripttype= "Text/javascript"src= "Examp

ECMASCRIPT5 defines 5 iterative methods for an array: every (), filter (), ForEach (), map (), some () Each method receives two parameters: the function to run on each item and, optionally, the scope object that runs the function-affects the value of this. The functions passed in these methods receive three parameters: the value of the array item, the position of the item in the array, and the object itself. Depending on the method used, the return value after the function is executed may or may
