比较全面的event对像在IE与FF中的区别 推荐_javascript技巧
window.event
IE:有window.event对象
FF:没有window.event对象。可以通过给函数的参数传递event对象。如onmousemove=doMouseMove(event)
鼠标当前坐标
IE:event.x和event.y。
FF:event.pageX和event.pageY。
通用:两者都有event.clientX和event.clientY属性。
鼠标当前坐标(加上滚动条滚过的距离)
IE:event.offsetX和event.offsetY。
FF:event.layerX和event.layerY。
标签的x和y的坐标位置:style.posLeft 和 style.posTop
IE:有。
FF:没有。
通用:object.offsetLeft 和 object.offsetTop。
窗体的高度和宽度
IE:document.body.offsetWidth和document.body.offsetHeight。注意:此时页面一定要有body标签。
FF:window.innerWidth和window.innerHegiht,以及document.documentElement.clientWidth和document.documentElement.clientHeight。
通用:document.body.clientWidth和document.body.clientHeight。
添加事件
IE:element.attachEvent(”onclick”, func);。
FF:element.addEventListener(”click”, func, true)。
通用:element.onclick=func。虽然都可以使用onclick事件,但是onclick和上面两种方法的效果是不一样的,onclick只有执行一个过程,而attachEvent和addEventListener执行的是一个过程列表,也就是多个过程。例如:element.attachEvent(”onclick”, func1);element.attachEvent(”onclick”, func2)这样func1和func2都会被执行。
标签的自定义属性
IE:如果给标签div1定义了一个属性value,可以div1.value和div1[”value”]取得该值。
FF:不能用div1.value和div1[”value”]取。
通用:div1.getAttribute(”value”)。
父节点、子节点和删除节点
IE:parentElement、parement.children,element.romoveNode(true)。
FF:parentNode、parentNode.childNodes,node.parentNode.removeChild(node)。

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 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.

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.

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'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 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 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.

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.
