Speaking directly from the method: 1, delete the node. RemoveChild (): If you do not know what the parent node of the node you want to delete is? You can use the ParentNode property. Like what: 2, replace the node. Repalcechild () Element.repalcechild (NewNode, OldNode); The new node is the guest, must first serve him slightly. The OldNode must be a child node of the element. Example: 3, find the node Finding nodes is relatively straightforward r

entry file:Inside the index file, we initialize an associative array to hold the functions that need to be used. and turn on the server.Server file:First, we set the encoded format of the received data to UTF-8, then register the listener for the "data" event to collect the new block of data received each time and assign it to the PostData variable, and finally, we move the call to the request route to the end event handler, To make sure it only fires when all data is received and fires only on

successive accesses are not affected by the visitor.Idempotent means that repeated requests are the same as the effect of a request more than once.Express has designed different route binding functions for each HTTP request methodWhere: The App.all function supports the binding of all request methods to the same response function, which is a very flexible function.4. Transfer of control rightsExpress supports multiple route response functions on the same path, but when accessing any path that i

variables, or global functions, put them outside the if,for, etc.The FOR function does not use the defined variable i directly, otherwise there will be a hidden danger (we should be very careful when using the For loop, put in a different position, may be different values)For example:1 DOCTYPE HTML>2 HTML>3 Head>4 Metahttp-equiv= "Content-type"content= "text/html; charset=utf-8">5 title>Untitled Documenttitle>6 7 8 9 Head>Ten One Body> A - inputtyp

1, Function: A function is a JS code that is defined once and can be invoked multiple times. When a function is called by an object, the function is called the method of the object. function Cssrain (x, y) { Code } Explain: Cssrain: For the function of the name; (): is an operator; X, y: as parameter; 2, the return value of the function: function A (x) { document.write (x); } function B (y) { document.wri

When using js, I often encounter some problems. I used my spare time to sort out some common problem solutions and post them to share with you, if you have any need, refer to section 1. Javascript Chinese and variables are case sensitive. 2. Single quotes and double quotes can be used to create strings without special differences in JavaScript. However, as a general rule, most developers prefer to use sing

undefined are equal.When checking for equality, null and undefined cannot be converted to other values.If an operand is NaN, the equal sign returns false, and the non-equal sign returns TRUE.If the two operands are objects, then their reference values are compared. If two operands point to the same object, then the equals sign returns TRUE, otherwise two operands are not equal.Relational operatorsOn both sides of the comparison operator if one is a numeric type and one is a different type, its
