<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>简jQuery左右对称浮动广告代码</title>
<link rel="stylesheet" href="css/style.css" />
</head>
<body>
<div style="height:2000px;"></div>
<!-- 代码部分begin -->
<div id="floatright" style="position: absolute; z-index: 10; "></div>
<script src="js/jquery.js" ></script>
<script src="js/floatAd.js" ></script>
<script>
window.onload = function(){
var ad2 = new FloatAd({
nodeLink : "<a href='广告连接地址'><img src='广告图片' border=0 /></a>" ,
floatObj : "floatleft",
x : 10,
y : 400,
locate : "left"
});
ad2.play();
}
</script>
<!-- 代码部分end -->
</body>
</html> In addition to introducing jquery (if you want to ask me what jquery is, please go out and turn left), the js file also needs:
var FloatAd = function(obj){
var mainNode = $("." + obj.main)[0];
if(obj.nodeLink && (typeof obj.nodeLink == "string")){
var newFloatObj = document.createElement("div");
newFloatObj.id = obj.floatObj;
newFloatObj.style.position = "absolute";
newFloatObj.style.zIndex = 10;
newFloatObj.innerHTML = obj.nodeLink;
document.body.appendChild(newFloatObj);
}
this.ad = document.getElementById(obj.floatObj);
this.main = document.getElementById(obj.main)||mainNode;
this.x = obj.x;
this.y = obj.y;
this.locate = obj.locate;
this.space = obj.space;
var that = this;
this.play = function(){
setInterval(function(){
that.calculate();
},10);
};
}
FloatAd.prototype = {
constructor : FloatAd,
calculate : function(){
var obj_x = this.x,
obj_y = this.y,
main_offsetLeft = document.documentElement.scrollLeft||document.body.scrollLeft,
main_offsetTop = document.documentElement.scrollTop||document.body.scrollTop;
if(this.main){
if(this.locate == "left"){
obj_x = this.main.offsetLeft - this.ad.offsetWidth - this.space;
}else if(this.locate == "right"){
obj_x = this.main.offsetLeft + this.main.offsetWidth + this.space;
}
if(this.ad.offsetLeft != main_offsetLeft + obj_x){
var dx = (main_offsetLeft + obj_x - this.ad.offsetLeft)*0.08;
dx = (dx > 0 ? 1 : -1)*Math.ceil(Math.abs(dx));
this.ad.style.left = this.ad.offsetLeft + dx + "px";
}
}else{
if(this.locate == "left"){
this.ad.style.left = obj_x + "px";
}else if(this.locate == "right"){
this.ad.style.right = obj_x +"px";
}
}
if(this.ad.offsetTop != main_offsetTop + obj_y){
var dy = (main_offsetTop + obj_y - this.ad.offsetTop)*0.08;
dy = (dy > 0 ? 1 : -1)*Math.ceil(Math.abs(dy));
this.ad.style.top = this.ad.offsetTop + dy + "px";
}
}
}This is what I compiled when I used this effect. I copied the cases online and organized them for everyone’s convenience.
2 Full-screen floating case: bay window!

js code:
var xPos = 300;
var yPos = 200;
var step = 1;
var delay = 30;
var height = 0;
var Hoffset = 0;
var Woffset = 0;

var xon = 0;
var pause = true;
var interval;
img1.style.top = yPos;
function changePos()

JavaScript Engines: Comparing Implementations
Apr 13, 2025 am 12:05 AM
Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.
Python vs. JavaScript: The Learning Curve and Ease of Use
Apr 16, 2025 am 12:12 AM
Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.
JavaScript: Exploring the Versatility of a Web Language
Apr 11, 2025 am 12:01 AM
JavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.

From C/C to JavaScript: How It All Works
Apr 14, 2025 am 12:05 AM
The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.
JavaScript and the Web: Core Functionality and Use Cases
Apr 18, 2025 am 12:19 AM
The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.
JavaScript in Action: Real-World Examples and Projects
Apr 19, 2025 am 12:13 AM
JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.
