How to get access to request object from custom handlebars helper

阅读更多关于 How to get access to request object from custom handlebars helper

问题 I'm using handlebars with node.js and express and I have a custom registered helper for temperature display that I'd like to have access to a query parameter from the page URL. The concept behind the helper is to handle Fahrenheit to Celsius conversion automatically based on whether ?tempFormat=F or tempFormat=C is in the URL or not. Here's the pseudo code for the custom helper I'd like to have: hbs.registerHelper("formatTemp", function(temp) { if (query parameter says to use Fahrenheit) {

composer是现代PHP的基石转自: https://www.itshutong.com/337.html 现代高级编程语言，依赖管理工具是必不可少的。Java有Maven，Python有pip，Nodejs有npm, 而在composer出现之前，PHP只有被广为诟病的Pear, 由于Pear实在太难用，很少PHP开发者用到这个工具。以致于PHP的开发生态很糟糕。连一个像样的依赖管理工具都没有，让PHP这门占据了web网站开发主流市场的语言很尴尬。开发过程中，要用到第三方的类库，需要去下载zip包，然后解压，放到相应的目录，处理好命名空间，自动加载的问题，如果这个第三方包还有其他依赖项，还要再次重复这个流程，看着隔壁家python和node.js一个命令行就搞定，显得php开发人员的操作既原始又滑稽。这场面，好比：所幸，金光闪闪的composer驾着七彩祥云来了，PHP终于有了真正意义的依赖管理工具。可以说，composer是现代PHP的基石。 composer解决了项目的依赖关系，且实现了自动加载。开发人员只需要几个命令行，就能获取其他开发者的包，PHP开发工作因此变得如同堆积木，可以根据业务的需求，快速方便地拆解组合代码。奇怪的是，即使compoer已经诞生好些年了，而且所有主流框架都支持composer，可竟然还有不少PHP开发者不用这个工具

问题 In js you can load a html template in the require part while defining a module. For example: template file : test.html <script id="test" type="text/template"> <div class="q-header-holder"> <h1> {{ quizName }}</h1> <a href="{{ instructionLinks }}" class="q-instruction-btn">Instructions</a> </div> </script> in module define( ["template/test"], function() { //.. rest of code .. } ); But this throws error while fetching the file the filename appended with .js extension.

How do I reference a field name that contains a dot in mustache template?

问题 How do I reference a field name that contains a dot in mustache template? For instance, if I have a view like { "foo.bar": "my value" } then how can I put my value into a template? Using {{foo.bar}} doesn't work because mustache thinks the dot is part of the path, like there should be a "foo" that has a "bar". 回答1: You can't read a key with a . in it from Mustache. The Mustache spec dictates that . is used to split content names. Mustache provides a means of escaping but only for HTML content

Mustache partials using variable syntax (without the “>”)?

阅读更多关于 Mustache partials using variable syntax (without the “>”)?

问题 I'm using mustache (php version) as my templating engine. I'm wondering if it's possible to have {{something}} serve as a partial, instead of having to format it as {{>something}} in the template. Ideally, a variable would be treated as a partial if the variable name is in the _partials array. This would allow me to change a variable to a partial without having to make any changes to templates. Is this possible? 回答1: I figured out how to do this by modifying the _renderTag function in

阅读更多关于 Mustache.js - Rendering only a limited number of array objects

问题 I recently inherited this from another developer, and what was left behind for me has me stumped. I am trying to build a set-up in which the first 3 objects in my JSON array are rendered on the page via mustache, then with a click, the next 3 load, and so forth. Where I'm stuck right now is just figuring out how to make Mustache only render 3 objects. I've done quite a bit of searching but I can't seem to find the syntax. There is no code associated with the 'load-more' button yet. I figured

Mustache-Java: How to get value in Map by key

阅读更多关于 Mustache-Java: How to get value in Map by key

问题 I am using JMustache in Java. I have Map variable in my Mustache template. How can I fetch a value at a particular key in the map, as we do in Java (map.get()). I know how to iterate through keys and values of a Map in a template. But I want a solution without iteration so that I can evaluate an expression such as: Data { "cities": [ { "Tokyo": { "overview": { "population": "19000000", "area": "450000" } } }, { "Sydney": { "overview": { "population": "4500000", "area": "6250000" } } } ] }

How to use Mustache in Twig templates? They both have the same tag delimiters

阅读更多关于 How to use Mustache in Twig templates? They both have the same tag delimiters

问题 I use Twig in my project. It uses these tags: {{ name }} I want to include Mustache in my project as well. But Mustache also uses the same tags {{ name }} , so there is a conflict and nothing works. The solution Mustache provides in their docs of course doesn't work. Because I have to type Twig delimiter {{ in my Twig template to change Mustache delimiter. * {{ default_tags }} {{=<% %>=}} * <% erb_style_tags %> <%={{ }}=%> * {{ default_tags_again }} How to pass over it? Is there any other way
