How would you create a JQuery / svg click-drag select outline effect?

只谈情不闲聊 提交于 2019-12-03 14:25:11
Not sure exactly what to call it, but I am looking for a way to create a dotted outline/selection box effect via javascript/svg when you click and drag over an area, and then goes away on mouseUp (that could be added if it wasn't an original part) . A jQuery library would be nice if it exists. I've done some looking around, and haven't found exactly what I am looking for. I guess the theory would be get the coord from the first click, track the mouse coord moment and adjust the box accordingly. But not writing it from scratch would be nice. Here's a demo I made just for you :) Demo (Static):

Why is Vue.js using a VDOM?

↘锁芯ラ 提交于 2019-12-03 13:32:38
According to Vue.js' documentation , it is using a VDOM under the hood to render the UI. From my understanding, the VDOM was mainly invented in order to avoid "tracked dependencies". With a VDOM, it is possible to reconcile bigger parts of the application without knowing what exactly has changed. As a result, one can use plain objects and arrays to describe the view and just needs to inform the framework about a change (like setState in React). Then, both VDOM trees are compared and the minimal set of required changes is applied to the real DOM. Vue.js, on the other hand, uses tracked

Use of boilerplate actions and reducers in redux

对着背影说爱祢 提交于 2019-12-03 13:12:37
I have been following the widely given advice of learning React development by first mastering component props , encapsulating UI state in component level this.state and passing it down selectively through the component tree. It's been an enlightening experience. I've come to appreciate the power of the stateless view design pattern and I feel that I've been able to achieve robust and well organized results using these techniques. Moving on, I am now trying to incorporate more sophisticated state management using redux . But as I wade through the complexity and integrate redux into my apps, I

Front End for Running Talend Jobs

前提是你 提交于 2019-12-03 12:06:39
I am looking for a front end for our operator to run our Talend jobs. We do not want him to have the ability to delete or modify jobs. Only to run them and monitor their results. Any suggestions for tools for doing this? Thanks The subscription version of Talend (called Talend Integration Suite, or TIS) has precisely that. It's a web-based console called Talend Administration Center (TAC) and it allows an operator to run jobs and monitor their results -- among many other things. The permissions can be set in the way you described, so that the operator is not able to delete or modify the jobs.

How can I make a GUI frontend to a command line tool in OSX?

风流意气都作罢 提交于 2019-12-03 09:51:30
问题 I'm dying to know how I can make a GUI for ffmpeg and jhead in OSX. I've been looking for a solution for a while and thought you, stackoverflow's users, could help me. Maybe you know some document I haven't come across of or, better, a tutorial to make a GUI. I love those two tools but I like the simplicity of drag/drop operations. Note: I don't need a GUI for them, I want to make one. 回答1: There is a tutorial for wrapping command-line tools using NSTask, on the Cocoa Dev Central site:

Fixed div inside scrolling div

拥有回忆 提交于 2019-12-03 09:44:35
I need to make the main of my site that has 980px width and 500px height (class="main") be fixed only when the mouse is over a scrolling div and has a height of 1500px and a width of 100% (class="container-scroll"), that is inside other div with height of 500px. (class="container") Pretty confused, right? I made a fiddle, I'm almost there, the problem is that if I set up the main to fixed, it will scroll with the page , not just inside the div This is my fiddle: https://jsfiddle.net/8oj0sge4/1/embedded/result/ HTML: <div id="wrapper"> <div class="container"> <div class="container-scroll"> <div

Use Clang to convert C++ to C code

我们两清 提交于 2019-12-03 09:08:49
I know that llvm can be used to convert c++ into c code. I was wondering if clang could do the same thing (seeing as clang was derived from llvm ). So can I use clang to convert c++ code into c code? If you want to know why I want to do this here is my scenario: PIC, which is a micro controller manufacturer, does not make c++ compilers, but does make c compilers for most of their products. I want to write in c++ and then as part of my build process, convert the c++ code into a temporary c file, which is then fed into the PIC compiler, and viola I have written c++ code for a PIC micro.

How to Build this Rounded Two Tone Donut Chart?

妖精的绣舞 提交于 2019-12-03 08:43:43
I'm trying to make a donut chart that looks like one below I'll be using angularJS, SVG and D3.js I've no clue how to get those rounded ends, Please help. Thanks. Simple answer: you use masks. We use a mask to draw the inner portion of the bezel. And a mask to cut the hole in the middle. The hole mask isn't really necessary. You could form the donut with thick lines. But it seemed easier to me to draw circular sectors, then make the hole. Here it is in SVG form. I'll leave the conversion to D3 to you. <svg width="600" height="600"> <defs> <!-- masks out the area outside and inside the inner

How to deal with browser's limit of parallel requests per domain in case of a priority AJAX request?

痴心易碎 提交于 2019-12-03 07:44:14
Imagine as given the following situation: There are about 20 requests (or even more) which has been triggered by our website. These can be any kind of requests - we don't know how to trigger them again. On this website, all the requests target the same url. The requests can have subscribed event listeners. In case of using Chrome, the first 6 requests are sent and the others are waiting in a queue to be sent (because of the parallel request limit per domain ). At this moment the webpage triggers a very important request (lets call it "VIR") which has a higher priority to be sent to the server
