Does anyone know how to generate UUID/GUID for Internet Explorer? I have code from Broofa at: http://www.broofa.com/2008/09/javascript-uuid-function/ this works fine on almost all the browsers except IE 9. this is how I do it: window.Guid = function () { function part() { return (((1 + Math.random()) * 0x10000) | 0).toString(16).substring(1).toUpperCase(); }; return {
有谁知道如何为Internet Explorer生成UUID / GUID？ 我有来自Broofa的代码：http://www.broofa.com/2008/09/javascript-uuid-function/ 这对几乎所有浏览器除了IE 9都能正常工作。 这是我如何做到的： window.Guid = function () { function part() { return (((1 + Math.random()) * 0x10000) | 0).toString(16).substring(1).toUpperCase(); }; return { NewGuid: function () { return (p
What I am trying to achieve is so that a marquee plays once when I click the button. My problem is that if I set the loop to 1 then it only plays once and then does nothing. My other problem is that it stops midway with my current code if I let go of the left mouse button. Or it stops where it was. Is there any way to make it either play once when the button is pressed and then play again whe
我想要实现的是当点击按钮时，一个选取框会播放一次。 我的问题是，如果我将循环设置为1，那么它只播放一次，然后什么都不做。 我的其他问题是，如果我放开鼠标左键，它会在当前代码的中途停下来。 或者它停止在那里。 有没有什么办法让它在按下按钮时播放一次，然后再次按下按钮再次播放，并让它完全完成循环。 这里是代码，我打算使用java脚本代替html。 这是我现在的代码： <marquee behavior="scroll" direction="u
I want to make unique instances of a set of cars that different people can hold. The cars will have similar base specs but some of their properties and methods will vary. The problem I have is that I can't work out how this should work. How do you deal with or create instances of instances in JavaScript? var Car = function(make, country) { this.make = make; this.country = country
我想制作一组不同人可以拥有的汽车的独特实例。 这些汽车将拥有类似的基本规格，但其中一些属性和方法会有所不同。 我的问题是我无法弄清楚这应该如何工作。 你如何处理或创建JavaScript实例实例？ var Car = function(make, country) { this.make = make; this.country = country; }; var Ferrari = new Car('Ferrari', 'Italy'); var fred = new Person() {}; var fred.cars['Ferrari'] = new Ferrari(1200, 300
How to check if variable contains valid UUID/GUID identifier ? I'm currently interested only in validating types 1 and 4, but it's not limit for your answer. Currently, UUID's are as specified in RFC4122. Therefore to validate a UUID... /^[0-9a-f]{8}-[0-9a-f]{4}-[1-5][0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$/i ...ensures you have a canonically formatted UUID that is Version
如何检查变量是否包含有效的UUID / GUID标识符？ 我目前只对验证类型1和4感兴趣，但对答案没有限制。 目前，UUID与RFC4122中的规定相同。 因此要验证UUID ... /^[0-9a-f]{8}-[0-9a-f]{4}-[1-5][0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$/i ...确保您具有版本1至5的标准格式的UUID，并且是根据RFC4122的相应Variant。 注：大括号{和}不是规范的。 它们是一些系统和用法的人造物。 易于修改上述正则表达式以满足原

I am developping a google chrome extension. My purpose is to send message from my script1.js to script2.js.

I'm sending a message from the content script to the background page. The message is a URL which then gets ajax parsed in the background. When I console.log the data retrieved into background.js the console log is pure html, but when I send the message back to my content script the message is suddenly in an object, and I'm not sure why. Here is my code: Content_Script.js: chrome.ru

When installing anything via npm, it downloads dozens of not needed files. Usually I am looking for a library final build, a *.min.js file or anything like that but the rest is useless. How do you handle all these useless files? Do you remove them by hand or generate the final app with any build tool like gulp or grunt ? I'm quite confused as I have plenty of npm modules installed in my
