js/jquery obtains the height and width of the browser window's visible area and the scroll bar height implementation code
Get the height and width of the visible area of the browser window. Friends who need the height of the scroll bar can refer to it.
In IE, the browser display window size can only be obtained as follows: Copy the code as follows
document.body.offsetWidth document.body.offsetHeight
In browsers that declare DOCTYPE, you can use the following to obtain the browser display window size: Copy the code as follows Code
document.documentElement.clientWidth document.documentElement.clientHeight
IE, FF, and Safari all support this method. Although opera supports this attribute, it returns the page size;
At the same time, all browsers except IE save this information in the window Object, you can use the following to obtain: The code is as follows Copy the code
window.innerWidth window.innerHeight
The general method of obtaining the size of the entire web page The code is as follows Copy the code
document.body.scrollWidth document.body.scrollHeight
The general method of obtaining the screen resolution height The code is as follows Copy the code
window.screen.height window.screen.width
Summarize the examples
function getViewSizeWithoutScrollbar(){//不包含滚动条
return {
width : document.documentElement.clientWidth,
height: document.documentElement.clientHeight
}
}
function getViewSizeWithScrollbar(){//包含滚动条
if(window.innerWidth){
return {
width : window.innerWidth,
height: window.innerHeight
}
}else if(document.documentElement.offsetWidth == document.documentElement.clientWidth){
return {
width : document.documentElement.offsetWidth,
height: document.documentElement.offsetHeight
}
}else{
return {
width : document.documentElement.clientWidth + getScrollWith(),
height: document.documentElement.clientHeight + getScrollWith()
}
}
}The differences between IE and FireFox are as follows:
IE6.0, FF1.06+:
clientWidth = width + padding clientHeight = height + padding offsetWidth = width + padding + border offsetHeight = height + padding + border IE5.0/5.5： clientWidth = width - border clientHeight = height - border offsetWidth = width offsetHeight = height
Attached is the most commonly used method for obtaining the full page width and height. Method (requires jquery framework) The code is as follows Copy the code
$(document).width() < $('body').width() ? $(document).width() : $('body').width(); $(document).height() < $('body').height() ? $(document).height() : $('body').height();
alert($(window).height()); //The height of the visible area of the current window of the browser
alert($(document). height()); //The height of the browser's current window document
alert($(document.body).height()); //The height of the browser's current window document body
alert($(document. body).outerHeight(true)); //The total height of the browser's current window document body includes border padding margin
alert($(window).width()); //The browser's current window visible area width
alert($(document).width());//The browser’s current window document object width
alert($(document.body).width());//The browser’s current window document body Height
alert($(document.body).outerWidth(true));//The total width of the browser's current window document body includes border padding margin
alert($(document).scrollTop() ); //Get the vertical height of the scroll bar to the top
alert($(document).scrollLeft()); //Get the vertical width of the scroll bar to the left

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 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.
Understanding the JavaScript Engine: Implementation Details
Apr 17, 2025 am 12:05 AM
Understanding 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: Development Environments and Tools
Apr 26, 2025 am 12:09 AM
Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.
The Role of C/C in JavaScript Interpreters and Compilers
Apr 20, 2025 am 12:01 AM
C 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.
Python vs. JavaScript: Use Cases and Applications Compared
Apr 21, 2025 am 12:01 AM
Python 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.
From Websites to Apps: The Diverse Applications of JavaScript
Apr 22, 2025 am 12:02 AM
JavaScript 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.
