This question already has an answer here: How do I write JSON data to a file? 10 answers From the flask documentation, If the mimetype is application/json this will contain the parsed JSON data. Otherwise this will be None . The key there is that .json is the parsed JSON data, not the original string. If you want to write it to a file, you'll need to convert it back to a string it

I'm using jQuery and Ajax for my forms to submit data and files but I'm not sure how to send both data and files in one form? I currently do almost the same with both methods but the way in which the data is gathered into an array is different, the data uses .serialize(); but the files use = new FormData($(this)[0]); Is it possible to combine both methods to be able to upload files a
我使用jQuery和Ajax来提交数据和文件,但我不确定如何以一种形式发送数据和文件? 我目前对这两种方法几乎一样,但数据收集到一个数组的方式不同,数据使用.serialize(); 但文件使用= new FormData($(this)[0]); 是否有可能将两种方法结合起来,以便能够通过Ajax将文件和数据上传到一种形式? 数据jQuery,Ajax和HTML $("form#data").submit(function(){ var formData = $(this).serialize(); $.ajax({
I found the answer here to the question below. I needed to setup a reverse proxy in apache which took about 2 minutes by adding the following line to my virual host; ProxyPass /couchdb/ http://dojo:5984/ Because of the same origin policy you can't post data across ports. I knew this applied to domains but not different ports so you set up a reverse proxy. I would like to know how I c
我在下面找到了答案。 我需要在apache中设置一个反向代理,花费大约2分钟时间,向我的虚拟主机添加以下行; ProxyPass / couchdb / http:// dojo:5984 / 由于相同的源策略,您不能在端口之间发布数据。 我知道这适用于域而不是不同的端口,所以你建立了一个反向代理。 我想知道如何使用JavaScript或jQuery将数据发布到couchDB。 我遵循这个啧啧,创建了一个数据库,我能够发布并使用curl获取数据,并且它一切正常。
I am going to ask the same question as JavaScript editor within Eclipse because it was written in 2010 and answers from 2008 are not true any more. So, "I'm looking for opinions on the best JavaScript editor available as an Eclipse plugin". Many thanks.

I have a (nested) data structure containing objects and arrays. How can I extract the information, ie access a specific or multiple values (or keys)? For example: var data = { code: 42, items: [{ id: 1, name: 'foo' }, { id: 2, name: 'bar' }] }; How could I access the name of the second item in items ? Preliminaries JavaScript has only one d
我有一个(嵌套的)数据结构包含对象和数组。 我如何提取信息,即访问特定或多个值(或键)? 例如: var data = { code: 42, items: [{ id: 1, name: 'foo' }, { id: 2, name: 'bar' }] }; 我怎么能访问name中的第二项的items ? 预赛 JavaScript只有一个数据类型可以包含多个值: Object 。 数组是一种特殊的对象形式。 (普通)对象具有这种形式 {key: value, k
I am evaluating sproutcore and cappuccino for use in my current project. Since I am a rails developer and I like pure javascript I think that sproutcore suits my style better. My problem is that every single sproutcore sample I have tested seems very slugish and slow on its user interface. Scrolling is very slow, clicking on buttons has a delay etc On the other hand all the cappuccino samples
我正在评估sproutcore和卡布奇诺用于我目前的项目。 由于我是一名rails开发人员,我喜欢纯JavaScript,所以我认为sproutcore更适合我的风格。 我的问题是,我测试过的每一个sproutcore样本在其用户界面上都显得非常糟糕和缓慢。 滚动速度非常慢,点击按钮有延迟等。另一方面,所有的卡布奇诺样本看起来都非常敏感,尽管事实上他们比sproutcore样本更全面的应用。 尽管目前令我的眼睛酸痛,但我没有潜入目标-j的问题。 你们
This question already has an answer here: Safely turning a JSON string into an object 22 answers Most browsers support JSON.parse() , which is defined in ECMA-262 5th Edition (the specification that JavaScript is based on). Its usage is simple: var json = '{"result":true,"count":1}', obj = JSON.parse(json); alert(obj.count); For the browsers that don't you can implement it using j
这个问题在这里已经有了答案: 安全地将JSON字符串转换为对象22个答案 大多数浏览器都支持JSON.parse() ,这是在ECMA-262第5版(JavaScript基于的规范)中定义的。 它的用法很简单: var json = '{"result":true,"count":1}', obj = JSON.parse(json); alert(obj.count); 对于那些不能使用json2.js实现的浏览器。 正如评论中指出的那样,如果您已经在使用jQuery,则会有一个$.parseJSON函数映射到JSON.parse如果可
In order to duplicate an Array in Javascript, does anyone know (and maybe tested) if it's faster to use: Slice method: var dup_array = original_array.slice(); or For loop: for(var i = 0, len = original_array.length; i < len; ++i) dup_array[i] = original_array[i]; UPDATE: (just to clarify myself) I know both ways do only a shallow copy : if original_array contains references to o
为了在JavaScript中复制数组, 有没有人知道(也许测试过)如果使用速度更快: 切片方法: var dup_array = original_array.slice(); 或For循环: for(var i = 0, len = original_array.length; i < len; ++i) dup_array[i] = original_array[i]; 更新:(只是为了澄清我自己)我知道这两种方法只做一个浅拷贝 :如果original_array包含对象的引用,对象将不会被克隆,但只有引用将被复制,因此两个数组都会引用相同
