I want to parse date without timezone in JavaScript. I have tried: new Date(Date.parse("2005-07-08T00:00:00+0000")); Returns Fri Jul 08 2005 02:00:00 GMT+0200 (Central European Daylight Time) new Date(Date.parse("2005-07-08 00:00:00 GMT+0000")); Returns same result new Date(Date.parse("2005-07-08 00:00:00 GMT-0000")); Returns same result I want to parse time: Without time zone. Witho
我想在JavaScript中解析没有时区的日期。 我努力了: new Date(Date.parse("2005-07-08T00:00:00+0000")); 退货周五2005年7月08日02:00:00 GMT + 0200 (中欧夏令时间) new Date(Date.parse("2005-07-08 00:00:00 GMT+0000")); 返回相同的结果 new Date(Date.parse("2005-07-08 00:00:00 GMT-0000")); 返回相同的结果 我想解析时间: 没有时区。 不调用构造函数Date.UTC或新日期(年,月,日)。 只需简单地将字
I tried this in the Chrome JS console, with my locale time zone set as PST: (new Date("07-15-2005")) => Fri Jul 15 2005 00:00:00 GMT-0700 (PDT) (new Date("07-15-2005")).getTime(); => 1121410800000 but.... (new Date("2005-07-15")) => Thu Jul 14 2005 17:00:00 GMT-0700 (PDT) (new Date("2005-07-15")).getTime(); => 1121385600000 I was expecting string parsing to occur in both.
我在Chrome的JS控制台中尝试了这一点,我的语言环境时区设置为PST: (new Date("07-15-2005")) => Fri Jul 15 2005 00:00:00 GMT-0700(PDT) (new Date("07-15-2005")).getTime(); => 1121410800000 但.... (new Date("2005-07-15")) => Thu Jul 14 2005 17:00:00 GMT-0700(PDT) (new Date("2005-07-15")).getTime(); => 1121385600000 我期待字符串解析发生在两个。 但是我不明白为什么使用YYYY-MM
Problem... Poorly-coded scripts exist which need to be included on a web page. These scripts pollute the global scope by doing things like: Assigning values to undeclared identifiers Adding properties to built-in constructor functions (like Object and Array ) and their prototypes Other nasty stuff. Solution? I want to include the scripts without the adverse side effects. I think it
问题... 存在需要包含在网页中的编码不佳的脚本。 这些脚本通过执行如下操作来污染全局范围: 将值分配给未声明的标识符 将属性添加到内置的构造函数(如Object和Array )及其原型 其他讨厌的东西。 解? 我想包括脚本没有不良副作用。 我认为这可以通过在iframe中加载脚本并将对象导出为父窗口的属性来实现。 以下是我迄今所得到的结果: <script> (function(){ var g=this, frameIndex=frames.length
What is the fundamental difference between bower and npm ? Just want something plain and simple. I've seen some of my colleagues use bower and npm interchangeably in their projects. npm is most commonly used for managing Node.js modules, but it works for the front-end too when combined with Browserify and/or $ npm dedupe . Bower is created solely for the front-end and is optimized with
bower和npm之间的根本区别是什么? 只是想要简单明了的东西。 我看到一些同事在他们的项目中交替使用了bower和npm 。 npm最常用于管理Node.js模块,但它与Browserify和/或$ npm dedupe结合使用时也可用于前端。 Bower专为前端而开发,并且在考虑到这一点的情况下进行了优化。 最大的区别是npm确实嵌套了依赖树(大小很大),而Bower需要一个平坦的依赖关系树(将依赖关系解析的负担放在用户上)。 嵌套的依赖关系树意味
有谁知道这两种方法有何区别: String.slice String.substring slice() works like substring() with a few different behaviors. Syntax: string.slice(start, stop); Syntax: string.substring(start, stop); What they have in common: If start equals stop : returns an empty string If stop is omitted: extracts characters to the end of the string If either argument is greater than the string's lengt
有谁知道这两种方法有何区别: String.slice String.substring slice()像substring() ,有几种不同的行为。 Syntax: string.slice(start, stop); Syntax: string.substring(start, stop); 他们有什么共同之处: 如果start等于stop :返回一个空字符串 如果省略stop :将字符提取到字符串的末尾 如果任一参数大于字符串的长度,则将使用该字符串的长度。 substring() 区别 : 如果start > stop ,那么substring将
What is the use of console.log ? Please explain how to use it in JavaScript, with a code example. It's not a jQuery feature but a feature for debugging purposes. You can for instance log something to the console when something happens. For instance: $('#someButton').click(function() { console.log('#someButton was clicked'); // do something }); You'd then see #someButton was cl
console.log什么用处? 请解释如何在JavaScript中使用它,并附上代码示例。 这不是一个jQuery功能,而是一个用于调试目的的功能。 例如,您可以在发生某些事情时将某些内容记录到控制台。 例如: $('#someButton').click(function() { console.log('#someButton was clicked'); // do something }); 当你点击按钮时,你会看到#someButton was clicked在Firebug的“控制台”选项卡(或其他工具的控制台 - 例如Chrome的W
I've seen it done differently in code out there, but is there any benefit or reason to doing a (blank params) .call / .apply over a regular () function execution. This of course is an over-simplified example var func = function () { /* do whatever */ }; func.call(); func.apply(); VERSUS just the simple parenthesis. func(); Haven't seen any information on this anywhere, I know why c
我已经在代码中看到了它的不同之处,但是在常规()函数执行过程中执行(空白params) .call / .apply是否有任何好处或原因。 这当然是一个过分简化的例子 var func = function () { /* do whatever */ }; func.call(); func.apply(); VERSUS只是简单的括号。 func(); 在任何地方都没有看到任何信息,我知道为什么在params通过时使用call / apply。 当你用func();调用一个方法时func(); ,方法内的this变量指向window
var obj = { name: "Simon", age: "20", clothing: { style: "simple", hipster: false } } for(var propt in obj){ alert(propt + ': ' + obj[propt]); } How does the variable propt represent the properties of the object? It's not a built-in method, or property. Then why does it come up with every property in the object? Iterating over properties requires this
var obj = { name: "Simon", age: "20", clothing: { style: "simple", hipster: false } } for(var propt in obj){ alert(propt + ': ' + obj[propt]); } 变量propt如何表示对象的属性? 它不是内置方法或属性。 那么为什么它会提供对象中的每个属性? 迭代属性需要额外的hasOwnProperty检查: for (var property in object) { if (object.hasOwnProperty(property)) { /
有什么方法可以在JavaScript中的指定范围内生成一个随机数(例如从1到6:1,2,3,4,5或6)? If you wanted to get between 1 and 6, you would calculate: Math.floor(Math.random() * 6) + 1 Where: 1 is the start number 6 is the number of possible results (1 + start (6) - end (1)) function randomIntFromInterval(min,max) { return Math.floor(Math.random()*(max-min+1)+min); } What it does "ext
有什么方法可以在JavaScript中的指定范围内生成一个随机数(例如从1到6:1,2,3,4,5或6)? 如果你想得到1和6之间的关系,你会计算出: Math.floor(Math.random() * 6) + 1 哪里: 1是起始号码 6是可能结果的数量(1 +开始(6) - 结束(1)) function randomIntFromInterval(min,max) { return Math.floor(Math.random()*(max-min+1)+min); } 它所做的“额外”是它允许不以1开头的随机时间间隔。例如,您可以获得从
如何在Javascript中的两个指定变量之间生成随机整数,例如x = 4和y = 8会输出4,5,6,7,8中的任意一个? There are some examples on the Mozilla Developer Network page: /** * Returns a random number between min (inclusive) and max (exclusive) */ function getRandomArbitrary(min, max) { return Math.random() * (max - min) + min; } /** * Returns a random integer between min (inclusive) and max (inclus
