Web Front-endJS TutorialAngularjs realizes text up and down seamless scrolling special effects code
I have no projects to do recently, so I learned some angularjs knowledge in my spare time, and then wrote an example of seamless scrolling of text up and down. It mainly wrote a small instruction.
css code:
Main control style
<style type="text/css">
*{margin: 0px;padding: 0px;}
.slide {width: 200px;height:200px;border:1px solid #dcdcdc;margin: 0 auto;margin-top: 50px;overflow: hidden;}
.slide li {height: 49px;line-height: 49px;text-align: left;padding: 0 10px;font-size: 16px;list-style: none;border-bottom: 1px dashed #dcdcdc;cursor: pointer;}
.slide li:hover{background: #ccc;}
</style>html code:
<body ng-app="tip"> <div ng-controller = "TipController"> <div class="slide"> <ul class="slideUl"> <!-- 指令 --> <slide-follow id="slide" dataset-data = "datasetData"></slide-follow> </ul> </div> </div> </body>
Of course our code is based on the angular that has been introduced into the page .js file is run down
slide-follow is the instruction we need to implement dataset-data = "datasetData" is the text js code we need to display
<script type="text/javascript">
var app =angular.module("tip",[]);
app.controller("TipController",function($scope){
// 数据可以根据自己使用情况更换
$scope.datasetData = [
{option : "这个是第一条数据"},
{option : "这个是第二条数据"},
{option : "这个是第三条数据"},
{option : "这个是第四条数据"},
{option : "这个是第五条数据"},
{option : "这个是第六条数据"}
]
})
.directive("slideFollow",function($timeout){
return {
restrict : 'E',
replace : true,
scope : {
id : "@",
datasetData : "="
},
template : "<li ng-repeat = 'data in datasetData'>{{data.option}}</li>",
link : function(scope,elem,attrs) {
$timeout(function(){
var className = $("." + $(elem).parent()[0].className);
var i = 0,sh;
var liLength = className.children("li").length;
var liHeight = className.children("li").height() + parseInt(className.children("li").css('border-bottom-width'));
className.html(className.html() + className.html());
// 开启定时器
sh = setInterval(slide,4000);
function slide(){
if (parseInt(className.css("margin-top")) > (-liLength * liHeight)) {
i++;
className.animate({
marginTop : -liHeight * i + "px"
},"slow");
} else {
i = 0;
className.css("margin-top","0px");
}
}
// 清除定时器
className.hover(function(){
clearInterval(sh);
},function(){
clearInterval(sh);
sh = setInterval(slide,4000);
})
},0)
}
}
})
</script> First we define what needs to be displayed in the controller Text, then we can start defining the instruction part.
Running rendering:
The text will scroll up and down seamlessly. When the mouse moves in, the timer will be cleared and the scrolling will stop.
The above is the angularjs code that the editor introduces to you to achieve seamless text scrolling up and down. I hope it will be helpful to you. If you have any questions, please leave me a message and the editor will promptly Reply to everyone. I would also like to thank you all for your support of the PHP Chinese website!

From Websites to Apps: The Diverse Applications of JavaScriptApr 22, 2025 am 12:02 AMJavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.
Python vs. JavaScript: Use Cases and Applications ComparedApr 21, 2025 am 12:01 AMPython is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.
The Role of C/C in JavaScript Interpreters and CompilersApr 20, 2025 am 12:01 AMC and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.
JavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AMJavaScript'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.
JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AMThe 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.
Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AMUnderstanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.
Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AMPython 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.
Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AMPython and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
