I have to add some interactive features to SVG directed graphs. So far the graphs I want to show are generated from a dot file and rendered as SVG. I'd like to know if there is some easy way to add interactivity (Maybe with Javascript) to such SVG documents. What I need is to display some information when the mouse goes over a node and to make it possible to compare two nodes. Since my
我必须添加一些交互功能到SVG有向图。 到目前为止，我想要显示的图形是从一个点文件生成的，并呈现为SVG。 我想知道是否有一些简单的方法来为这些SVG文档添加交互性（可能带有Javascript）。 我需要的是当鼠标移过一个节点并且可以比较两个节点时显示一些信息。 由于我的模型是自动生成的，因此我宁愿保留点生成的SVG，并用独立的Javascript来添加其他信息。 我有一个内联SVG的例子。 这个SVG和你所拥有的区别在于，我
Let's say that I have two accordion tabs. The first one loads hundreds of images and is open when the page loads. I want to be able to stop the images from downloading if the user clicks on the second accordion tab. Will changing the src attributes of the images via js stop the images from downloading? Or do the requests just continue until completion and not show up on the page? I hav
假设我有两个手风琴选项卡。 第一个加载数百个图像，并在页面加载时打开。 如果用户点击第二个手风琴选项卡，我希望能够停止下载图像。 通过js更改图像的src属性是否会停止下载图像？ 或者请求是否继续直到完成并且不显示在页面上？ 我有一个脚本，可以在3秒钟内载入SO标志，我已经提出了另一个问题。 http://alexturpin.net/slowimage/slowimage.php 使用它，我试图重现这个问题： var img = new Image(); img.onloa
From this code: HTML <div class="test"></div> CSS .test { background-color:red; font-size:20px; -custom-data1: value 1; -custom-data2: 150; -custom-css-information: "lorem ipsum"; } With javascript -- for example from a $('.test') -- how can I get a list of the CSS attributes wich have the property name starting with the prefix "-custom-" ?
从这个代码： HTML <div class="test"></div> CSS .test { background-color:red; font-size:20px; -custom-data1: value 1; -custom-data2: 150; -custom-css-information: "lorem ipsum"; } 使用javascript - 例如从$('.test') - 我怎样才能得到一个CSS属性的列表，其中的属性名称以“-custom-”开头？ （它们可以有各种名称，但始终是相同的前缀） 我想得到这个： { cu
I've been trying to wrap my head around how javascript functions and scope work, and it just doesn't make sense to me. Can someone please explain why the following code outputs: 'animal says meow' instead of 'kitty says meow'? (function($, exports){ var animal = function(){}; exports.Animal = animal; })(jQuery, window); (function($, Animal){ var kitty = new Animal
我一直在试图围绕javascript函数和范围如何工作，而这对我来说没有任何意义。 有人可以解释为什么下面的代码输出：'动物说喵'而不是'猫咪说喵'吗？ (function($, exports){ var animal = function(){}; exports.Animal = animal; })(jQuery, window); (function($, Animal){ var kitty = new Animal; kitty.sayHi = function(){ console.log(this); console.log('says meow'); } $($.prox
How do I get the number of days between two dates in JavaScript? For example, given two dates in input boxes: <input id="first" value="1/1/2000"/> <input id="second" value="1/1/2001"/> <script> alert(datediff("day", first, second)); // what goes here? </script> Here is a quick and dirty implementation of datediff , as a proof of concept to solve the problem as presen
我如何获得JavaScript中两个日期之间的天数？ 例如，给定输入框中的两个日期： <input id="first" value="1/1/2000"/> <input id="second" value="1/1/2001"/> <script> alert(datediff("day", first, second)); // what goes here? </script> 这里是一个快速和肮脏的实施datediff ，作为概念验证作为问题提出来解决这个问题。 它依赖于这样的事实，即可以通过减去两个日期之间的时间间隔来获取
for meta data on the page using attribute names like table:rowNum:<name> , eg, var row = document.createElement('tr'); row.setAttribute('tup','emp:1'); row.setAttribute('emp:1:pkid','123'); have been using colon-delimited names (eg, name='emp:1:emp_id' ) for years with good success, but today got bit with colon delimited attribute names in particular: var el2 = row.parentNode
在页面上使用像table:rowNum:<name>这样的属性名称的元数据table:rowNum:<name> ，例如， var row = document.createElement('tr'); row.setAttribute('tup','emp:1'); row.setAttribute('emp:1:pkid','123'); 多年来一直使用冒号分隔的名字（例如， name='emp:1:emp_id' ），但今天得到了冒号分隔的属性名称 尤其是： var el2 = row.parentNode.querySelector("[emp:1:pkid]"); => `Error: SYNTAX
I'm working on a way to make keyboard shortcuts. Initially I had done this: function clicking(e) { var code; if (!e) var e = window.event; if (e.keyCode) code = e.keyCode; else if (e.which) code = e.which; var character = String.fromCharCode(code); if(character == 'X' && e.ctrlKey) { window.location = 'http://www.example.org/';
我正在努力制作键盘快捷键。 最初我这样做了： function clicking(e) { var code; if (!e) var e = window.event; if (e.keyCode) code = e.keyCode; else if (e.which) code = e.which; var character = String.fromCharCode(code); if(character == 'X' && e.ctrlKey) { window.location = 'http://www.example.org/'; } } 用户可以按下Ctrl和
I'm trying to get some textarea formatting going on my site using TinyMCE... I'm a little new to integrating this kind of thing and could use some help. I'm using their jQuery plugin 3.4.x found here. I can't seem to get any kind of effect on my textareas! They still look like the regular textareas from before integrating this code. I'm following this tutorial. Here is
我试图让我的网站使用TinyMCE进行一些textarea格式化...我对集成这种东西有点新，可以使用一些帮助。 我正在使用他们的jQuery插件3.4.x。 我似乎无法对我的textareas产生任何影响！ 他们仍然看起来像集成此代码之前的常规textareas。 我正在学习这个教程。 这是我使用的脚本（ script_url是正确的）： <script src="tiny_mce/tiny_mce.js"></script> <script type="text/javascript" src="tiny_mce/jquer
If I insert some html via js after the doc.ready than checked='checked' radio button doesn't render as checked in Google Chrome also, I noticed that if I remove the name attribute from the input than it works here is the whole thing: <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.js" type="text/javascript"></script> <
如果我在doc.ready之后通过js插入一些html，比check ='checked'单选按钮在Google Chrome中不显示为已选中状态 另外，我注意到，如果我从输入中删除名称属性比它的作品 这是整个事情： <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.js" type="text/javascript"></script> </head> <body> <script type='text/javascript'> $(fu
C# 6.0 has just been released and has a new nice little feature that I'd really like to use in JavaScript. They're called Null-conditional operators. These use a ?. or ?[] syntax. What these do is essentially allow you to check that the object you've got isn't null , before trying to access a property. If the object is null , then you'll get null as the result of your pr
C＃6.0刚刚发布，并有一个新的漂亮的小功能，我真的很喜欢用JavaScript。 它们被称为空条件运算符。 这些使用?. 或?[]语法。 这些操作基本上允许您在尝试访问属性之前检查您拥有的对象是否为null 。 如果该对象为null ，那么您将因为您的属性访问而得到null 。 int? length = customers?.Length; 所以这里int可以是null，如果customers为null，将会取这个值。 更好的是你可以链接这些： int? length = customers?.order
