Recursive iteration over an object in Jade template?

阅读更多关于 Recursive iteration over an object in Jade template?

问题 I have an object of mixed type properties - some strings, some arrays of strings, some objects containing arrays of strings - that can potentially go many levels deep. I would like to iterate over all properties so that an object creates a div, an array creates a div, and a string property creates a span to contain the text. { "string" : "some text", "object" : { "array" : [ "text" ] } } The above object would render as: <span>some text</span> <div> <div> <span>text</span> </div> </div> But

阅读更多关于 Access values using {{#each}} in a one dimensional array

I've found a lot of examples of using the {{#each}} helper to iterate over multi-dimensional arrays, but I can't figure out how to access each value in a one-dimensional array. For example, take this array: skills: ['Design', 'Development', 'HTML5', 'CSS', 'JavaScript'], How do I output each item, in a helper like below? template: Handlebars.compile( '<div>' + '{{#each skills}} {{ the_item_output }} {{/each}}' + '</div>' ), What do I need to put in placed of {{ the_item_output }} to see the actual item? {{#each skills}} <li>{{this}}</li> {{/each}} An array of scalar values should make use of

advanced string formatting vs template strings

阅读更多关于 advanced string formatting vs template strings

问题 I was wondering if there is a advantage of using template strings instead of the new advanced string formatting? 回答1: Templates are meant to be simpler than the the usual string formatting, at the cost of expressiveness. The rationale of PEP 292 compares templates to Python's % -style string formatting: Python currently supports a string substitution syntax based on C's printf() '%' formatting character. While quite rich, %-formatting codes are also error prone, even for experienced Python

How do I stop Smarty throwing an error when I'm using AngularJS in the same template. I have a Smarty page template with this code: <li ng-repeat="i in items"> <p class="item">{{i}}</p> </li> And I'm getting a blank page when I view in a browser.

knockout.js loading templates at runtime

阅读更多关于 knockout.js loading templates at runtime

I am using knockout.js with its inbuilt templating system. I define the templates as so: <script type="text/html" id="subjectItemView"> <span class="name" data-bind="text: subjectName" /> </script> I then use the id of the template so having this as part of the script is a necessity. I have a fair few of these templates in my single page application and have recently moved to using require.js to load the scripts that are required only when they are required. I would like to do the same with the templates, preferably using require.js so that my modules could list the templates as dependencies.

阅读更多关于 in velocity can you iterate through a java hashmap's entry set()?

问题 Can you do something like this in a velocity template? #set ($map = $myobject.getMap() ) #foreach ($mapEntry in $map.entrySet()) <name>$mapEntry.key()</name> <value>$mapEntry.value()</value> #end it outputs blank tags like so: <name></name> and <value></value> What am I doing wrong? 回答1: Your mistake is referring to key and value as methods (with trailing "()" parenthesis) instead of as properties. Try this: #set ($map = $myobject.getMap() ) #foreach ($mapEntry in $map.entrySet()) <name>

app.set and app.engine in Express

阅读更多关于 app.set and app.engine in Express

问题 I am following a Node.js tutorial. Two lines for which I am not sure are: app.set('view engine', 'html'); app.engine('html', hbs.__express); I checked the documentation for app.set and it only tells me: Assigns setting name to value. But my question is what's the relevance of using this. I googled it and wherever app.engine is used app.set is called before. Let me know the significance of using app.set before the app.engine . EDIT I found the following line, but I am still unclear as I am
