Take this class: var MyClass = new Class({ Implements: [Events, Options], initialize: function() { this.a = 1; }, myMethod: function() { var mc = new differentClass({ events: { onClick: function() { console.log(this.a); // undefined (should be 1, 2, 3 etc) this.a ++; } } }); } }); How do I keep the value of this.a ? I am basically trying to draw a line (using canvas) from the last point to the co-ordinates just clicked. [EDIT] I dont want to bind this as it's bad apparently and it will over-ride the differentClass options. several patterns are available. decorator via .bind() var mc = new

将文本复制到剪贴板的最佳方法是什么？ （多浏览器） 我试过了： function copyToClipboard(text) { if (window.clipboardData) { // Internet Explorer window.clipboardData.setData("Text", text); } else { unsafeWindow.netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect"); const clipboardHelper = Components.classes["@mozilla.org/widget/clipboardhelper;1"].getService(Components.interfaces.nsIClipboardHelper); clipboardHelper.copyString(text); } } 但是在Internet Explorer中，它会给出语法错误。 在Firefox中，它说 unsafeWindow is not defined 。 一个没有闪光灯的好技巧： Trello如何访问用户的剪贴板？ #1楼 我发现以下解决方案： 在按下按键时，处理程序会创建“ pre”标签。 我们将内容设置为复制到此标签

Can any one reply me which of the javascript frameworks are better to implement on my project? jQuery or Mootools? It's a matter of what coding style do you prefer and can help you in the long term. Just because other people use jQuery doesn't make it any easier for me to learn the way that it's coded. This is a must for you to read before you go any further: http://jqueryvsmootools.com/ MooTools has the better API and once you actually use it, you'll see how the design choices make sense. Try them both, but you'll stay for the extendability of MooTools In the last performance comparison I

I'm getting many reports that the mousewheel behaves differently in different browsers when using this scrollbar class. In some browsers (like Firefox) it's extremely slow while in others (mostly newer versions of Safari on Snow Leopard) it's perfect. Any ideas what's going on here and how to fix it? I'm using the Mootools library. One line to pay attention to here is the wheel: (Browser.firefox) ? 20 : 1 line. This is where you set the speed or steps for the mousewheel. Here it is set up in a jsFiddle: http://jsfiddle.net/brandondurham/6SUyM/ var ScrollBar = new Class({ Implements: [Events,

今天我们开始第五讲，在上一讲（ 《Mootools 1.2教程(4)——函数》 ）中，我们学习了在MooTools 1.2中建立和使用函数的几种不同方式。下一步就是理解事件了。和选择器类似，事件也是建立互动界面的一个重要部分。一旦你掌握了一个元素，你需要去决定什么行为来触发什么效果。先把效果留着以后在讲，我们首先看一看中间步骤和一些常见的事件。 左键单击事件 左键单击事件是web开发中最常见的事件。超链接识别点击事件，然后把你带到另外一个URL地址。MooTools能够识别其他DOM元素上的点击事件，在设计和功能上给了你极大的灵活性。给一个元素添加一个点击事件的第一步： // 通过$('id_name') 取得一个元素 // 用.addEvent添加事件 // ('click')定义了事件的类型 $('id_name').addEvent('click', function(){ // 在这里添加点击事件发生时你要执行的任何代码 alert('this element now recognizes the click event'); }); 你也可以把这个函数从.addEvent();独立出来来完成相同的事情： var clickFunction = function(){ // 在这里添加事件发生时你要执行的任何代码 alert('this element now
