This question already has an answer here: Fetching zipped text file and unzipping in client browsers, feasible in Javascript? 3 answers letting the browser uncompress it with Content-Encoding: gzip is probably the best. In case it doesn't work for your scenario, there are many LZW implementations in javascript like: https://gist.github.com/revolunet/843889 you might have to try out di
这个问题在这里已经有了答案： 获取压缩文本文件并在客户端浏览器中解压缩，在Javascript中可行吗？ 3个答案 让浏览器使用Content-Encoding解压缩它：gzip可能是最好的。 如果它不适合你的场景，那么javascript中有很多LZW实现：https：//gist.github.com/revolunet/843889 你可能不得不尝试不同的实现，我没有自己检查它们中的任何一个。
This has been killing me the last few days. Not even kidding, but I've been really stressing over this trying to solve it. I am currently trying to use affine transformation matrices to create an isometric projection in HTML5. I receive a tile which is a square that is rotated 45 degrees (essentially a square diamond on a square canvas). I then scale one of the axis' depending on if
这在过去的几天里一直在杀我。 甚至没有开玩笑，但我一直在强调这个试图解决它。 我目前正在尝试使用仿射变换矩阵在HTML5中创建等距投影。 我收到一个正方形的瓷砖，它旋转了45度（基本上是方形画布上的方形钻石）。 然后根据x或y方向上是否存在三角形来缩放其中一个轴。 然后，我将轴倾斜一个因子以适应。 然后，我通过将它旋转回-45度来否定初始旋转。 目前，我的仿射矩阵是： // note: the difference in z is
I'm trying to learn nodejs and I thought the best way to do this would be to try doing some stuff without using express or any other non-core modules. I'm stuck on trying to get some text and an image to be delivered simultaneously. The code I'm trying is: var http = require('http'); var fs = require('fs'); var server = http.createServer(function(request,response) { fs.readFi
我试图学习nodejs，我认为最好的方法是尝试做一些不使用express或任何其他非核心模块的东西。 我一直试图让一些文本和图像同时传送。 我正在尝试的代码是： var http = require('http'); var fs = require('fs'); var server = http.createServer(function(request,response) { fs.readFile('my_pic.jpg', function(error, file) { response.writeHead(200, {'content-type':'text/html'}); response.wr
I'm noticing sometimes when I load my site (and when doing pingdom tests, etc) that the site just hangs and turns white, but as soon as you "refresh" the page everything loads properly. I don't really know where to start. When I run waterfall reports from https://www.dotcom-tools.com/ a majority of the locations load perfectly fine, but 4 or 5 each time load in 50 seconds.
当我加载我的网站（以及进行pingdom测试等）时，我会注意到网站只是挂起并变成白色，但只要“刷新”页面，所有内容都会正确加载。 我不知道从哪里开始。 当我从https://www.dotcom-tools.com/运行瀑布报告时，大部分位置的加载完全正常，但每次在50秒内加载4或5次。 www.rubytuesdaybenefits.com/ft 有任何想法吗？！
I'm using Angular UI Bootstrap 0.8.0 along with AngularJS 1.2.15 to display some content in accordions. One of the accordions contain a form with input/select elements. I'm having a select dropdown with a list of countries with a ng-model on it to show the selected value. ng-model is initialized by a custom directive 'initialize-model' on the select element which initializes th
我正在使用Angular UI Bootstrap 0.8.0和AngularJS 1.2.15来显示手风琴中的一些内容。 其中一个手风琴包含一个带有输入/选择元素的表单。 我有一个选择下拉列表，其上带有ng模型的国家列表以显示选定的值。 ng-model由select元素上的自定义指令'initialize-model'初始化，该元素将模型初始化为HTML标签的value属性。 这些选项是使用服务器端模板（ZPT）生成的。 在其他浏览器中，当我选择一个国家时，保存表单并再
I am performing messaging via websockets between a HTML5 client and server running on node.js. Naturally I chose JSON as the message format and as such created common javascript code, defining the various message content types and transformation operations. The javascript code is shared between both projects. I created my web client as one git project and my server as another git project. Pa
我正在通过运行在node.js上的HTML5客户端和服务器之间的websockets执行消息传递。 当然，我选择了JSON作为消息格式，并创建了常见的JavaScript代码，定义了各种消息内容类型和转换操作。 JavaScript代码在两个项目之间共享。 我创建了我的Web客户端作为一个git项目，我的服务器作为另一个git项目。 部分原因是我使用phonegap为各种基于触摸的环境构建基于webkit的客户端。 这也是各种逻辑的一个很好的分离。 为了共享通
This works. var a = 'ontouchstart' in window; for (;;) { console.log(a); break; } This causes syntax error. Why? for (var a = 'ontouchstart' in window;;) { console.log(a); break; } This works. for (var a = ('ontouchstart' in window);;) { console.log(a); break; } This causes syntax error. Why? To avoid confusion with for-in-loops. The syntax specification for for-loops is ex
这工作。 var a = 'ontouchstart' in window; for (;;) { console.log(a); break; } 这会导致语法错误。 为什么？ for (var a = 'ontouchstart' in window;;) { console.log(a); break; } 这工作。 for (var a = ('ontouchstart' in window);;) { console.log(a); break; } 这会导致语法错误。 为什么？ 为了避免与for-in-loop混淆。 for循环的语法规范是明确的： IterationStatement : for ( Expressi
I have a data array which contains many objects (JSON format). The following can be assumed as the contents of this array: var data = [ { "name": "Jim", "age" : 25 }, { "name": "Jerry", "age": 27 } ]; Now, I display these details as: <div ng-repeat="person in data | filter: query"> </div Here, query is modeled to an input field in which the user can restrict
我有一个数据数组，其中包含许多对象（JSON格式）。 以下内容可以假定为这个数组的内容： var data = [ { "name": "Jim", "age" : 25 }, { "name": "Jerry", "age": 27 } ]; 现在，我将这些细节显示为： <div ng-repeat="person in data | filter: query"> </div 在此，将查询建模为用户可以限制显示的数据的输入字段。 现在，我有另一个位置显示当前显示的人数/ Showing {{data.length
I thought this would be a very common thing, but I couldn't find how to handle it in AngularJS. Let's say I have a list of events and want to output them with AngularJS, then that's pretty easy: <ul> <li ng-repeat="event in events">{{event.title}}</li> </ul> But how do I handle the case when the list is empty? I want to have a message box in place where
我认为这将是一件非常常见的事情，但我无法在AngularJS中找到如何处理它。 假设我有一个事件列表并希望用AngularJS输出它们，那么这很简单： <ul> <li ng-repeat="event in events">{{event.title}}</li> </ul> 但是，如果列表为空，我该如何处理这种情况呢？ 我希望有一个消息框，其中的列表与“没有事件”或类似的东西。 唯一会接近的是带有events.length的ng-switch （如何检查是否为空而不是
I have the following code. I would like to have it such that if price_result equals an integer, let's say 10, then I would like to add two decimal places. So 10 would be 10.00. Or if it equals 10.6 would be 10.60. Not sure how to do this. price_result = parseFloat(test_var.split('$')[1].slice(0,-1)); 你可以使用toFixed（）来做到这一点var twoPlacedFloat = parseFloat(yourString).toFixed(2)
我有以下代码。 我想这样做，如果price_result等于一个整数，让我们说10，然后我想添加两个小数位。 所以10将是10.00。 或者如果它等于10.6将是10.60。 不知道如何做到这一点。 price_result = parseFloat(test_var.split('$')[1].slice(0,-1)); 你可以使用toFixed（）来做到这一点var twoPlacedFloat = parseFloat(yourString).toFixed(2) 当你使用toFixed ，它总是以字符串形式返回值。 这有时会使代码复杂化。 为了避
