I need to develop a client heavy web application that works on Android tablets. It must work with the default browser and maybe as PhoneGap application. So I need a tablet for testing. Previously I have had really bad experiences with Android browsers. My HTC Desire Z does not show JavaScript exceptions in Android LogCat. If an exception occurs it just dies silently and there is no way to t
我需要开发一款适用于Android平板电脑的客户端沉重网络应用程序。 它必须与默认浏览器一起工作，也许可以作为PhoneGap应用程序。 所以我需要一台平板电脑进行测试。 以前，我对Android浏览器的体验非常糟糕。 我的HTC Desire Z在Android LogCat中不显示JavaScript异常。 如果发生异常，它只是静静地死去，没有办法知道是什么引发了异常。 那么，已知哪些Android平板电脑会显示例外情况？ 堆栈痕迹很棒，但我的希望不是
Is it possible to manipulate the way booleans are stringified? Changing Boolean.prototype.toString doesn't seem to help. Here my tests within mozrepl and FF3. repl> Boolean.prototype.toString=function (){return this==true ? "1" : ""} function() {…} repl> a.toString() "" repl> a=true true repl> a.toString() "1" repl> a+"" "true" repl> a=false false repl> a+"" "false"
是否有可能操纵布尔值串化的方式？ 改变Boolean.prototype.toString似乎没有帮助。 在这里我的测试在mozrepl和FF3。 repl> Boolean.prototype.toString=function (){return this==true ? "1" : ""} function() {…} repl> a.toString() "" repl> a=true true repl> a.toString() "1" repl> a+"" "true" repl> a=false false repl> a+"" "false" 我对ECMA规范的理解是+应该调用toString() 。 更新：
Take a look at this JsFiddle: var requests = [ $.ajax("http://search.twitter.com/search.json", { data: { q: 'ashishnjain' }, dataType: 'jsonp' }) .done(function() {console.log("request");}), $.ajax("http://search.twitter.com/search.json", { data: { q: 'ashishnjain' }, dataType: 'jsonp' }) .done(function() {console.log("request");}) ]; $.when(requests).done(console.log("alldone"));
看看这个JsFiddle： var requests = [ $.ajax("http://search.twitter.com/search.json", { data: { q: 'ashishnjain' }, dataType: 'jsonp' }) .done(function() {console.log("request");}), $.ajax("http://search.twitter.com/search.json", { data: { q: 'ashishnjain' }, dataType: 'jsonp' }) .done(function() {console.log("request");}) ]; $.when(requests).done(console.log("alldone")); 预期的输
I have just finished reading this article on Javascript modules. I can understand that CommonJS modules are synchronously loaded while AMD modules are asynchronously loaded. What I don't understand is that how can I module become magically synchronous if I write it in the CommonJS format, or how it becomes magically async if I write it in the AMD format. I mean javascript does not have a
我刚读完这篇关于Javascript模块的文章。 我可以理解CommonJS模块是同步加载的，而AMD模块是异步加载的。 我不明白的是，如果我使用CommonJS格式编写模块，我怎么才能使模块变得奇迹般地同步，或者如果我以AMD格式编写它，它如何变成奇迹般的异步。 我的意思是JavaScript没有define或甚至require关键字。 他们只是规格而不是库。 我的意思是模块加载的行为取决于模块加载器，而不是模块的结构。 如果是这种情况，为什么
I know this question hast probably been asked a thousand times, but i cannot seem to find the answer. I want result to be the data returned from the ajax-request, which should be a json-data array (the result of console.log(data) ). var result = $.ajax({ type: 'GET', url: dataPath, dataType: 'json', success: function(data) { console.log(data) }, error: function
我知道这个问题可能被问过一千次，但我似乎无法找到答案。 我希望result是从ajax-request返回的数据，它应该是一个json-data数组（ console.log(data)的结果）。 var result = $.ajax({ type: 'GET', url: dataPath, dataType: 'json', success: function(data) { console.log(data) }, error: function(){ //alert("damn"); }, data: {}, aync: false }); conso
Code example: http://jsfiddle.net/MhEPw/1/ I have two jQuery Deferred objects. I want to have more than one 'async' request happening - and after they all run I want the callbacks (the .done functions) to be run in order they were specified in. Unfortunately they don't run in order. Maybe I am looking for some functionality here that Deferred doesn't provide? What you need
代码示例：http://jsfiddle.net/MhEPw/1/ 我有两个jQuery Deferred对象。 我想要发生多个“异步”请求 - 并且在它们全部运行后，我希望回调函数（.done函数）按照它们的指定顺序运行。不幸的是，它们不能按顺序运行。 也许我正在寻找一些延迟不提供的功能？ 你需要做的是将你的所有请求与一个主延迟对象连接起来，并在你的承诺中注册所有的回调。 主延迟对象需要监听各个请求并相应地进行解析。 达到此目的的最简单方法
I'm trying to send an SMS for a function. But the problem is: The function takes about 10-15 seconds to finish (Since we do bunch of stuff with PhantomJS). _.each(users, function(userData){ // This does not work since i need to wait for 15 seconds smsFree.sendSMSFree(userData, productUrl); }); I've even tried using setTimeout but that didn't quite work as well. I'm on NodeJ
我正在尝试发送短信给某个功能。 但问题是：该功能需要大约10-15秒才能完成（因为我们用PhantomJS完成了一堆东西）。 _.each(users, function(userData){ // This does not work since i need to wait for 15 seconds smsFree.sendSMSFree(userData, productUrl); }); 我甚至尝试过使用setTimeout，但这并没有很好的工作。 我在NodeJS上。 我如何利用异步或其他库来解决我的问题？ 我想等待15秒，然后循环到第二个对象
I am trying to run an asynchronous loop async.each over an array of objects. On each object in the array, I am trying to run two functions sequentially (using promises ). The problem is that async.each only runs for the first keyword. In the following code, getKeywords loads some keywords from a file, then returns an array of keyword objects. Each keyword object is put into searchKeyword tha
我试图在一个对象数组上运行异步循环async.each 。 在数组中的每个对象上，我试图按顺序运行两个函数（使用promises ）。 问题是async.each只运行第一个关键字。 在下面的代码中， getKeywords从文件加载一些关键字，然后返回一个关键字对象数组。 每个关键字对象都放入searchKeyword中进行搜索。 然后使用InsertSearchResults将搜索结果放入数据库中。 在我看来，每个关键字应该被并行处理，并且搜索和插入功能被链接。
Basically I am trying to scrap some data from website and perform the DOM extraction, deletion and updation on a callback function binded to the 'end' event of http.request . I have returned the data from the 'end' event callback too but it is not receiving in my route callback function. I get undefined there. Below is the code block: var scraper = { extractEmail: functi
基本上我试图从网站上http.request一些数据，并在绑定到http.request的'end'事件的回调函数上执行DOM提取，删除和更新。 我也从'end'事件回调中返回了数据，但它没有在我的路由回调函数中接收。 我在那里弄undefined明白。 以下是代码块： var scraper = { extractEmail: function (directoryName) { var result = getDirectory(directoryName); if (result !== 404) { va
I'm scraping r/theonion and writing the titles to a text file, onion.txt. After that, I am intending to scrape r/nottheonion and writing the titles to a text file, nottheonion.txt. I succeed in writing to onion.txt, but not to nottheonion.txt. var onion_url = "https://www.reddit.com/r/theonion"; var not_onion_url = "https://www.reddit.com/r/nottheonion"; var promise = new Promise(function
我正在抓取r / theonion并将标题写入文本文件onion.txt。 之后，我打算把这些标题写入文本文件nottheonion.txt。 我成功写入onion.txt，但不写入notononion.txt。 var onion_url = "https://www.reddit.com/r/theonion"; var not_onion_url = "https://www.reddit.com/r/nottheonion"; var promise = new Promise(function(resolve, reject) { request(onion_url, function(error, response, html) { if (error)
