In order to debug javascript in my heroku production environment, I need to disable asset compression (or at least compression of javascript). I tried config.assets.compress = false along with config.assets.debug = true , and the compressed assets were still used. I then deleted the compressed assets, at which point no assets were rendered at all. I added config.assets.enabled = false , which
为了在我的heroku制作环境中调试javascript，我需要禁用资产压缩（或者至少压缩javascript）。 我试着config.assets.compress = false以及config.assets.debug = true ，并且仍然使用压缩资产。 然后我删除了压缩资产，此时根本没有任何资产被呈现。 我添加了config.assets.enabled = false ，这没有帮助。 我尝试将未压缩的资源复制到各种目录中，包括应用程序根目录，公共资源和公共资源（后两个使用文件夹“images”，“java
I use grunt-sass and grunt-watch to compile and minify my code grunt.config('watch', { scripts: { files: ['<%= project.src.js.directory %>/*.js'], tasks: ['concat:scripts', 'uglify:compile'] }, styles: { files: [ '<%= project.src.css.directory %>/**/*.scss' ], tasks: ['sass:compile', 'cssmin:minify'] } }); Problem: When I modif

这是否会用于测试位置“index”处的值是否存在，还是有更好的方法： if(arrayName[index]==""){ // do stuff } All arrays in JavaScript contain array.length elements, starting with array[0] up until array[array.length - 1] . By definition, an array element with index i is said to be part of the array if i is between 0 and array.length - 1 inclusive. That is, JavaScript arrays are linear, starting
这是否会用于测试位置“index”处的值是否存在，还是有更好的方法： if(arrayName[index]==""){ // do stuff } JavaScript中的所有数组都包含array.length元素，从array[0]开始直到array[array.length - 1] 。 根据定义，如果i介于0和array.length - 1之间，则索引为i的数组元素被认为是数组的一部分。 也就是说，JavaScript数组是线性的，从零开始并达到最大值，并且数组没有从数组中排除某些值或范围的机制。 要找出一
So, i'm trying to implement hough transform, this version is 1-dimensional (its for all dims reduced to 1 dim optimization) version based on the minor properties. Enclosed is my code, with a sample image... input and output. Obvious question is what am i doing wrong. I've tripled check my logic and code and it looks good also my parameters. But obviously i'm missing on something.
所以，我试图实现hough变换，这个版本是基于次要属性的1维（其所有变暗减至1个暗淡优化）版本。 封闭的是我的代码，带有示例图像...输入和输出。 明显的问题是我做错了什么。 我翻了三倍检查我的逻辑和代码，它看起来也很好，我的参数。 但显然我错过了某些东西。 注意，红色像素应该是椭圆中心，而蓝色像素是要去除的边缘（属于符合数学方程的椭圆）。 另外，我不感兴趣openCV / matlab / ocatve /等..使用（没有任何
I am trying to use canvas so that with a mouse a person can write their signature. Everything works until I stretch or scroll the screen then it draws the line in a different place away from the mouse. The Code: function onMouseUp(event) { 'use strict'; mousePressed = false; } function onMouseMove(event) { 'use strict'; if (mousePressed) { event.preventDefault();
我正在尝试使用画布，以便用鼠标可以写出他们的签名。 一切工作，直到我伸展或滚动屏幕，然后它在与鼠标不同的地方绘制线条。 代码： function onMouseUp(event) { 'use strict'; mousePressed = false; } function onMouseMove(event) { 'use strict'; if (mousePressed) { event.preventDefault(); mouseX = event.clientX - can.offsetLeft - mleft; mouseY = event.clientY - ca
Suppose I have map like this: var map = {"a" : 100, "b" : 200, "c": 700}; And I want an Array consisting of "a" 100 times, "b" 200 times and "c" 700 times: map_array = [a, a, a, a, ... a, b, b, b, ... b, c, c, c, ... c] Simple solution is to just loop the frequency times and push in the array: var map_array = [] for(key in map) { for(var i=1; i <= map[key
假设我有这样的地图： var map = {"a" : 100, "b" : 200, "c": 700}; 我想要一个包含“a”100次，“b”200次和“c”700次的数组： map_array = [a, a, a, a, ... a, b, b, b, ... b, c, c, c, ... c] 简单的解决方案就是循环频率并推入数组： var map_array = [] for(key in map) { for(var i=1; i <= map[key] ; i++) { map_array.push(key) } } 但是，这显然需要时间来处理大量数据，我们可以采取措施来
I'm trying to create a form of scatterplot. I have a custom x-axis and a specific scale for both a-axis. I have implemented a zoom functionality for it as well. So far everything is fine, but when I finally try to plot my data as circles I get two errors: . My graph can be viewed on this website: http://servers.binf.ku.dk/hemaexplorerbeta/ (the circles are huge, because I want to make
我正在尝试创建一个散布图的形式。 我有一个自定义的x轴和两个a轴的特定比例。 我也为它实现了缩放功能。 到目前为止，一切都很好，但是当我最终尝试将数据绘制为圆时，出现两个错误： 。 我的图可以在这个网站上查看：http：//servers.binf.ku.dk/hemaexplorerbeta/（这个圈子很大，因为我想确保我在他们之前知道他们的位置） 我基于从MYSQL服务器读取的数据创建我的圈子。 我检查了我的所有数据，数字是正确的。 他

In my slide show project, user can swipe left or right to show pervious or next image. This is easy by using jquery mobile swipe event on the slide show container. However, user want to append a click event to it, when they click on the image, it will open in a new tab. Therefore I wrap the <img> tap in <a> . The problem is when user swipe the picture very quickly, the click event
在我的幻灯片放映项目中，用户可以向左或向右滑动以显示上一张或下一张图片。 在幻灯片放映容器上使用jquery移动滑动事件很容易。 但是，用户想要为其添加点击事件，当他们点击图片时，它会在新标签中打开。 因此，我在<a>包装<img>水龙头。 问题出在用户非常快速地滑动图片时，点击事件也会被触发。 $(" .carousel").swiperight(function (e) { $(this).carousel('prev'); });
