Are CDATA tags ever necessary in script tags and if so when? In other words, when and where is this: <script type="text/javascript"> //<![CDATA[ ...code... //]]> </script> preferable to this: <script type="text/javascript"> ...code... </script> A CDATA section is required if you need your document to parse as XML (eg when an XHTML page is interpreted as XML) an
在脚本标记中是否需要CDATA标记，如果是的话？ 换句话说，何时何地是这样的： <script type="text/javascript"> //<![CDATA[ ...code... //]]> </script> 更可取的是： <script type="text/javascript"> ...code... </script> 如果需要将文档解析为XML（例如，当将XHTML页面解释为XML），并且希望能够写入文字i<10和a && b而不是i<10和a && b a &am
The http request sent to some 'request_url' returns json response in format {'succes': 1, 'html': 'thestuff'} so when jQuery.ajax({ url: 'request_url', success: function(response){ alert(response.html); //'thestuff' is here as expected } }); 'thestuff' can be found in response.html as expected. But if this ajax is called inside the '
发送给某个'request_url'的http请求以格式{'succes'：1，'html'：'thestuff'}返回json响应 所以当 jQuery.ajax({ url: 'request_url', success: function(response){ alert(response.html); //'thestuff' is here as expected } }); 按照预期，可以在response.html中找到'thestuff'。 但如果这个ajax在另一个ajax请求的'成功'回调中被调用，那么response.h
Is it possible to create an HTML fragment in an AngularJS controller and have this HTML shown in the view? This comes from a requirement to turn an inconsistent JSON blob into a nested list of id : value pairs. Therefore the HTML is created in the controller and I am now looking to display it. I have created a model property, but cannot render this in the view without it just printing the HT
是否有可能在AngularJS控制器中创建一个HTML片段，并将该HTML显示在视图中？ 这是因为需要将不一致的JSON blob转换为id : value对的嵌套列表。 因此，HTML是在控制器中创建的，现在我正在寻找它来显示它。 我已经创建了一个模型属性，但不能在视图中渲染它，只需要打印HTML。 更新 看起来问题在于将创建的HTML呈现为引号内的字符串。 将试图找到解决这个问题的方法。 示例控制器： var SomeController = function ()
I'm trying to decide on a standard for json responses for my applications going forwards. So I'm thinking something along the lines of Fake Json { Message:"hello, this is a reponse", action: 0 or 1, or "Good" or "bad", statusCode: 234, } I'm wondering if there is a good standard for this already, and also how I can keep my standards in sync between
我正在尝试为我的应用程序前进的JSON响应标准做出决定。 所以我在思考一些问题 假Json {消息：“你好，这是一个响应”，行动：0或1，或“好”或“坏”，statusCode：234，} 我想知道是否已经有一个很好的标准，以及我如何保持我的标准在我的前端和后端之间同步？ 有没有一个聪明的方法来做到这一点？ 我正在使用类似于这样的结构： { status: ("ok", "error" or "redirect"), message: "some message goes here.", fields: "
I have a prototype solution in AngularJS and it is working with the following data structure: $scope.clients = [ { client:"Client1", projects:[ { project: "Project1", items:[ { item: "This is the first item" }, { item: "This is the second item" } ]}, { project: "Project2", items:[ { item: "This is the third item" }, { i
我在AngularJS中有一个原型解决方案，它使用以下数据结构： $scope.clients = [ { client:"Client1", projects:[ { project: "Project1", items:[ { item: "This is the first item" }, { item: "This is the second item" } ]}, { project: "Project2", items:[ { item: "This is the third item" }, { item: "This is the fourth item" }
this question is difficult to summarize in a question title UPDATE I created a JSFiddle that builds an obfuscated string out of your input based on the letters extracted from this question: You can access it here, or would a gist be easier? I recently came across a fun bit of obfuscated JavaScript in this profile that looks like this: javascript:[[]+1/!1][1^1][1>>1]+({}+[])[1<<1^
这个问题很难在题目中总结 更新我创建了一个JSFiddle，它基于从这个问题中提取的字母，从输入中生成一个模糊的字符串：你可以在这里访问它，或者一个要点会更容易吗？ 我最近在这个配置文件中遇到了一些模糊的JavaScript，看起来像这样： javascript:[[]+1/!1][1^1][1>>1]+({}+[])[1<<1^11>>1]+([]+!!- [])[1<<1]+[/~/+{}][+!1][-~1<<1]+([]+/-/[(!!1+[])[1>>1]+(!!1 +[])[1<<1^1
This question already has an answer here: Why does ++[[]][+[]]+[+[]] return the string “10”? 8 answers Because empty string ("") is false in javascript (As Javascript is a dialect of ECMAScript, and ECMAScript language specification clearly defines this behavior) and + unary operator converts false to 0 . Reference : http://www.ecma-international.org/publications/files/ECMA-ST/Ec
这个问题在这里已经有了答案： 为什么++ [[]] [+ []] + [+ []]返回字符串“10”？ 8个答案 由于空字符串 ("")在JavaScript中为false （因为Javascript是ECMAScript的一种方言，ECMAScript语言规范明确定义了此行为），并且+ 一元运算符将false转换为0 。 参考 ：http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-262.pdf
This question already has an answer here: Why does ++[[]][+[]]+[+[]] return the string “10”? 8 answers Check out jsfuck.com. This gives examples and shows how to, quite literally, write any code using it. The basics: false => ![] true => !![] undefined => [][[]] NaN => +[![]] 0 => +[] 1 => +!+[] 2 => !+[]+!+
这个问题在这里已经有了答案： 为什么++ [[]] [+ []] + [+ []]返回字符串“10”？ 8个答案 检查jsfuck.com。 这给出了例子并说明了如何使用它来编写任何代码。 基础： false => ![] true => !![] undefined => [][[]] NaN => +[![]] 0 => +[] 1 => +!+[] 2 => !+[]+!+[] 10 => [+!+[]]+[+[]] Array => [] Numbe
This question already has an answer here: Why does ++[[]][+[]]+[+[]] return the string “10”? 8 answers You can use only six different characters to write and execute any JS code. For example here are some representations to JS constructs false => ![] true => !![] undefined => [][[]] NaN => +[![]] 0 => +[] 1 => +!+[] 2
这个问题在这里已经有了答案： 为什么++ [[]] [+ []] + [+ []]返回字符串“10”？ 8个答案 您只能使用六个不同的字符来编写和执行任何JS代码。 例如，这里是一些JS构造的表示 false => ![] true => !![] undefined => [][[]] NaN => +[![]] 0 => +[] 1 => +!+[] 2 => !+[]+!+[] 10 => [+!+[]]+[+[]] Array => []
This question already has an answer here: Why does ++[[]][+[]]+[+[]] return the string “10”? 8 answers First break out your code to this: !![] which returns true (!! is to convert to boolean) and now + converts to number so +!![] returns 1. ![] converts to false so +![] returns 0. ~[] returns -1 and ~![] also returns -1 . ~!![] returns -2 . Now, -~!![] returns 2 and -~![] returns 1.
这个问题在这里已经有了答案： 为什么++ [[]] [+ []] + [+ []]返回字符串“10”？ 8个答案 首先将您的代码分解为： !![]返回true（!!将转换为布尔值），现在+转换为数字so +!![]返回1。 ![]转换为false，所以+![]返回0。 ~[]返回-1 ， ~![]也返回-1 。 ~!![]返回-2 。 现在， -~!![]返回2 ， -~![]返回1。 所以，结合他们都会返回10162014。 所有关于你知道的是〜，！，+，＆ - ![] = false; #作为一个表达式
