问题 I'm trying to reuse some control elements in my Meteor app. I'd like the following two templates to toggle visibility and submission of different forms. <template name='addControl'> <img class='add' src='/images/icon-plus.png' /> </template> <template name='okCancelControl'> <img class='submit' src='/images/icon-submit.png' /> <img class='cancel' src='/images/icon-cancel.png' /> </template> I'll call these templates in another: <template name='insectForm'> {{#if editing}} <!-- form elements -

问题 I'm configuring a static site generator using Grunt's Assemble.io. I'm using the Pages Collection to build a navigation list like so: {{#each pages }} <li><a href="{{{filename}} }">{{{title}} }</a></li> {{/each }} I would also like to apply class="active" to the navigation item for the current page, but I'm not sure how to approach this.

问题 Given an array of objects, I would like to use one property of a nested object to look up various properties in an associated object in Handlebars. In this example, I would like to show a list of students at each university, and information about the department to which each student belongs. My code works, but the nested lookups are very repetitive: {{lookup (lookup ../majors major) 'dean'}} {{lookup (lookup ../majors major) 'location'}} Is there anything I can do about this? I'd like to do

问题 I want to create a form to input custom keys and values of an object in an mongo/mongoose schema to eventually see in a handlebars view. See example to better explain.

问题 I want to implement a custom switch case with default value with the help of the Register Helper function in HandlebarsJs.

问题 I'm a bit new to Node and javascript backend frameworks so please bear with me: I've been searching around to find a nice combination of front-end, back-end (MVC)frameworks to work with Node, and I've currently decided upon using SailsJS/EmberJS to make a boilerplate which I can play around with and maybe use for future projects. SailsJs (out of the box generated app) uses EJS to compile back-end views. EmberJs (by default, starter kit) uses handlebars to compile front-end views. I want to

There's no newline in the file. 回答1: It's on the handlebarsjs.com, but not documented well enough (for me);
