Is there a way to use patterns/textures using addSVG for jsPDF?

I have SVG images generated using the D3 library and they look great. Problem is, addSVG can't use them. I verified that 'regular' SVGs work, I can do basic shapes, strokes, color fills. Is there a way to get the patterns in there? Ideally, could I extend addSVG to handle dataURIs or perhaps build a CSS with the pattern fills? If that doesn't work, then maybe a way to parse

有没有办法使用jsPDF的addSVG使用模式/纹理?

我有使用D3库生成的SVG图像,它们看起来很棒。 问题是,addSVG不能使用它们。 我证实'常规'SVG的工作,我可以做基本的形状,笔画,颜色填充。 有没有办法让模式在那里? 理想情况下,我是否可以扩展addSVG来处理dataURIs,或者可以使用模式填充来构建CSS? 如果这不起作用,那么可能是一种解析SVG XML字符串的方法吗? 如果不是其中的任何一种,有没有办法在“常规”SVG中创建一些可替代的模式? 也许有一个比D3

Convert SVG to image (JPEG, PNG, etc.) in the browser

Open a Websocket connection from Meteor.js

How can we open a Websockets connection from Meteor? Can we do something like: ws = new WebSocket('ws://localhost/path'); ws.on('open', function() { ws.send('something'); }); ws.on('message', function(message) { console.log('received: %s', message); }); Error: ReferenceError: WebSocket is not defined Using socket.io npm package var io = Meteor.require('socket.io') var socket = io.c

Render view component with parameters into named outlet ember.js

I have 2 named outlets in my application template, slider-area and pre-footer . Is there a way to pass view components that take parameters, as in the main-slider component shown in the index template, to a named outlet? So I would need to pass {{main-slider sliders=filteredSlider}} to the outlet {{outlet "slider-area"}} in the index template? I have come from rails so forgive my th

将带有参数的视图组件渲染到名为outlet的ember.js中

我在我的应用程序模板, slider-area和pre-footer有2个指定插座。 有没有一种方法可以将视图组件传递给一个指定的出口,如同在索引模板中显示的main-slider组件那样传递参数? 所以我需要将{{main-slider sliders=filteredSlider}}传递给索引模板中的插座{{outlet "slider-area"}} 。 我来自铁轨,所以原谅我的想法,如果这不是多么肮脏。 可以在应用程序模板中指定yield :slider_area ,然后在content_for :slid

Draggable code not working with hammer.js

I've successfully implemented jQueryUI draggable, but as soon as I add hammer.js code, the draggable code no longer works. It is not as soon as I include hammer.js, but as soon as I use the script. Why is this? How can I get them both to work? Both the draggable and hammer are applied to .dataCard and #main The draggable code works fine here ( with hammer implementation commented out

可拖曳的代码不能与hammer.js一起使用

我已经成功实现了jQueryUI可拖动,但只要添加hammer.js代码,可拖动代码就不再起作用。 它不是我包含hammer.js,但只要我使用脚本。 为什么是这样? 我怎样才能让他们都能工作? .dataCard和#main都适用于可拖动和锤子 可拖动的代码在这里工作正常(用锤子实现注释掉):http://goo.gl/MO5Pde 以下是可拖动代码的示例: $('#main').draggable({ axis:'y', revert:true, start: function(event, ui){

MDN "Object.is" alternative proposal

I have read the MDN page on the "Object.is" method. It gives an alternative code for the browsers that do not provide this method: if (!Object.is) { Object.is = function(v1, v2) { if (v1 === 0 && v2 === 0) { return 1 / v1 === 1 / v2; } if (v1 !== v1) { return v2 !== v2; } return v1 === v2; }; } The questi

MDN“Object.is”替代方案

我已经阅读了“Object.is”方法中的MDN页面。 它为不提供此方法的浏览器提供了一个替代代码: if (!Object.is) { Object.is = function(v1, v2) { if (v1 === 0 && v2 === 0) { return 1 / v1 === 1 / v2; } if (v1 !== v1) { return v2 !== v2; } return v1 === v2; }; } 问题很简单:第二个“if”是否成立? 感谢您的关注。 它有点写在同

Regex: Matching the first letter(s) of multiple words

So I am really bad at regex stuff ... I googled for an hour now and the best answer I could find is this one. But I still can't for the sake of me figure it out ... What I need is the following: I have a JS array I need to .filter() . This arrays contains for example: [ 'Gurken halbiert 2kg', 'Karotten geschnitten 5kg', 'Gurken RW' ] For example: All of the following inputs should ma

正则表达式:匹配多个单词的第一个字母

所以我在正则表达式方面非常糟糕......现在我搜索了一个小时,我能找到的最好答案就是这个。 但我仍然不能为了我而弄明白...... 我需要的是以下内容: 我有一个JS数组我需要.filter() 。 这个数组包含例如: [ 'Gurken halbiert 2kg', 'Karotten geschnitten 5kg', 'Gurken RW' ] 例如: 以下所有输入应匹配第一项( "Gurken halbiert 2kg" ): "Gu ha" "gur h" "gu halbi&qu

Play full HTML5 video and then loop a section of it

I'm trying to play an 8.6 second video once completely, and then loop a small section of the video infinitely, to keep the illusion of a never-ending video. So far I've looked into the media fragments URI, and the ended event of the video. Setting the currentTime attribute in the ended event listener works, but it makes the video "blink". At present, I'm using a timeupda

播放完整的HTML5视频,然后循环播放部分内容

我试图完全播放一段8.6秒的视频,然后无限循环一小段视频,以保持视频永无止境的幻觉。 到目前为止,我已经查看了媒体片段的URI以及视频的结束事件。 在结束事件监听器中设置currentTime属性有效,但会使视频“闪烁”。 目前,我使用timeupdate事件侦听器来改变视频接近结束的时间[如下所示] elem.addEventListener('timeupdate', function () { if (elem.currentTime >= 8.5) { elem.currentTime = 5; elem.play()

Downloading files in a SPA

How does one go about setting up file download in a Single Page Application, without triggering a reload? I have had a situation where a PDF file is generated on the server and needs to be given to the client for download. Sending it as an application/octet-stream does nothing useful in a SPA, because files can't be sent over AJAX. The best I came up with is saving the generated file in

在SPA中下载文件

如何在单页面应用程序中设置文件下载,而不触发重新加载? 我遇到了在服务器上生成PDF文件并需要下载到客户端的情况。 将它作为应用程序/八位字节流发送在SPA中没有任何用处,因为无法通过AJAX发送文件。 最好的办法是将生成的文件保存在服务器上的临时文件夹中,将文件的URL发送到客户端并执行window.open(url) 。 问题是不同的浏览器以不同的方式打开文件。 例如,默认情况下,Firefox使用PDF.js打开相同选项卡中的PDF
