About I'm working on a Firefox Add-on using the Firefox Add-on SDK. The add-on will be site specific and it will hide certain elements based on user preferences. I already made this add-on a few years back, but with the new SDK things work a bit different. Code Because the add-on is site specific and I need to modify the content of the site I use the 'PageMod' module [main.
关于 我正在使用Firefox附加SDK开发Firefox插件。 该插件将特定于站点,并会根据用户偏好隐藏某些元素。 几年前我已经制作了这个附加组件,但是对于新的SDK,其工作方式有点不同。 码 由于插件是特定于站点的,我需要修改站点的内容,我使用'PageMod'模块 [main.js] pageMod.PageMod({ include: "*.ipvisie.com", contentScriptFile: [ data.url('jquery-1.11.1.min.js'), data.url('script.js')
How can I upload large images to the GPU using webgl without freezing up the browser (think of high-res skyboxes or texture atlases)? I thought at first to seek if there's a way to make texImage2D do its thing asynchronously (uploading images to the GPU is IO-ish, right?), but I could not find any way. I then tried using texSubImage2D to upload small chunks that fit in a 16 ms time window
如何在不冻结浏览器的情况下使用webgl将大图像上传到GPU(想想高分辨率天空盒或纹理图集)? 我首先想到的是,是否有办法让texImage2D异步执行(将图像上传到GPU是IO-ish,对不对?),但是我找不到任何方法。 然后,我尝试使用texSubImage2D上传适合16毫秒时间窗口的小块(我瞄准60 fps)。 但texSubImage2D只有在传递ArrayBufferView时才会使用偏移量AND宽度/高度参数 - 传递Image对象时,只能指定偏移量,它会(我猜测)
Having read Dr Rauschmayer's description of recursive tail call optimisation in es6, I've since been trying to recreate the 'zero-stack' execution of the recursive factorial function he details. Using the Chrome debugger to step between stack frames, I'm seeing that the tail optimisation is not occurring and a stack frame is being created for each recursion. I've also
读过了Rauschmayer博士对es6中递归尾部调用优化的描述后,我一直试图重新创建他详细描述的递归阶乘函数的'零栈'执行。 使用Chrome调试器在栈帧之间进行切换,我发现没有发生尾部优化,并且为每个递归创建了一个栈帧。 我也尝试通过在没有调试器的情况下调用函数来测试优化,但是将100000传递给阶乘函数。 这会引发“最大堆栈”错误,这意味着它实际上并未优化。 这是我的代码: const factorial = (n, acc = 1) =&g
Could someone explain, why do we use callback in JavaScript? I found examples, but they could be implemented by using the normal functions. What is the advantage of using it? I got answers to "how" to use it and not "why and when" do we need to use it. Typically, I found it being used in AJAX. on the httpRequest.onreadystatechange . Is this similar to Java's multi-t
有人可以解释一下,为什么我们在JavaScript中使用回调? 我找到了一些例子,但它们可以通过使用普通函数来实现。 使用它的优点是什么? 我得到了“如何”使用它的答案,而不是“为什么和什么时候”需要使用它。 通常,我发现它在AJAX中使用。 在httpRequest.onreadystatechange 。 这与Java的多线程相似吗? 响应的听众如何以及在哪里? 异步编程类似于多线程吗? 在下面的代码中,控制流程如何: function some_function
I have created a tree control using kendo TreeView.it has more than 10,000 nodes and i have used loadOnDemand false when creating Tree. I am providing a feature to expand the tree by its level, for this i have created a method which takes the parameter "level" as number and expand it accordingly and user can enter 15 (max level) into the method, it works fine with 500 to 600 nodes for
我使用kendo创建了一个树控件TreeView.it拥有超过10,000个节点,并且在创建树时我使用了loadOnDemand false。 我提供了一个功能来扩展树的级别,因为我创建了一个方法,它将参数“level”作为数字并相应地展开,用户可以在该方法中输入15(最大级别),它可以正常工作所有级别都有500到600个节点,但是当树有超过5000个节点时,如果用户试图扩展到第二级节点之上,那么浏览器挂起并显示没有响应的错误。 我为扩展树而创建的方法
I don't really know what's going on here. Every time I try to upload a file, all the file contains is: ------WebKitFormBoundaryJ0uWMNv89fcUsC1t-- I have searched for the past 2 days for some sort of explanation, but I am just going in circles. I have no idea why this is happening. Form: <form id="upload-file" ecntype="multipart/form-data"> <input name="picture" type=
我真的不知道这里发生了什么事。 每次我尝试上传文件时,所有文件都包含: ------WebKitFormBoundaryJ0uWMNv89fcUsC1t-- 我已经搜索了过去2天的某种解释,但我只是在圈圈。 我不知道为什么会发生这种情况。 形成: <form id="upload-file" ecntype="multipart/form-data"> <input name="picture" type="file"> <input type="button" value="Upload" id="upload-button" /> </form> 使
I have a UI where users are scrolling a horizontally scrolling area. I still want them to be able to scroll left and right, but I'd like to fire an Hammer.js pan event at the same time. Here's my code at present: var worksHammertime = new Hammer(scrollingArea); worksHammertime.on('pan', function(ev) { if ( ev.direction === 2 ) { log('left', ev) Do things... } else { lo
我有一个用户在滚动水平滚动区域的用户界面。 我仍然希望他们能够左右滚动,但我想同时发起Hammer.js pan事件。 这是我目前的代码: var worksHammertime = new Hammer(scrollingArea); worksHammertime.on('pan', function(ev) { if ( ev.direction === 2 ) { log('left', ev) Do things... } else { log('right', ev) Do things... } }); 基本上我想我正在寻找Hammer默认使用的preventDefault()行
Are there any Ruby / Python features that are blocking implementation of optimizations (eg inline caching) V8 engine has? Python is co-developed by Google guys so it shouldn't be blocked by software patents. Or this is rather matter of resources put into the V8 project by Google. What blocks Ruby, Python to get Javascript V8 speed? Nothing. Well, okay: money. (And time, people, res
有没有阻止V8引擎优化的实现(例如内联缓存)的Ruby / Python功能? Python由Google合作开发,所以不应该被软件专利所阻挡。 或者这相当于Google投入V8项目的资源问题。 什么阻止Ruby,Python获得Javascript V8的速度? 没有。 好吧,好吧:钱。 (时间,人员,资源,但如果你有钱,你可以购买这些。) V8拥有一支精干,高度专业化,经验丰富(因而薪水高)的工程师队伍,拥有数十年的经验(我个人正在谈论 - 几乎
I am trying to use latin-square library for node.js in a loop to find some pattern, run the script and after 2 minutes have this error: RangeError: Maximum call stack size exceeded var latinSquare = require("latinsquare"); var lookup; var loop; lookup = ls(); console.log("first: "+ lookup); /*----------------------------------------------------------------------------------------------

I'm using Webpack for my JS application. For the styles I'm using Sass. My application is pretty big, so I'm using a lot of @mixins and @includes. In the last couple of days (while the app's SASS-data grew a bit more) I faced the same following error multiple times: "Uncaught RangeError: Maximum call stack size exceeded". Did anyone of you have this issue with Sass
我为我的JS应用程序使用Webpack。 对于我使用Sass的样式。 我的应用程序很大,所以我使用了很多@mixins和@includes。 在过去的几天里(应用程序的SASS数据增加了一些),我多次遇到以下相同的错误:“Uncaught RangeError:Maximum call stack size exceeded”。 Sass之前有没有人对Sass有过这个问题? 这种错误通常在那里发生? 编辑: 好吧,我发现,递归不是问题。 它适用于Mac的Firefox和大多数Windows浏览器,但
