What you’re looking for the is the concat helper. Using it, your second example would become: {{#my-modal modal-id=(concat ‘add-item-‘ title) header=(concat ‘New ‘ title)}} <p>My body blabla</p> {{/my-modal}}
I needed this solution solved in the same way the original poster expected. Therefore I created a helper function to do this for me. function setVariable(varName, varValue, options){ options.data.root[varName] = varValue; }; Contained within the options in the helper, is the data block, with the root of the helper variables. I placed my variable within … Read more
This is a great question and, in my mind, a glaring weakness in Express’s view model. Fortunately, there is a solution: use Handlebars block helpers. Here’s the helper I use for this purpose: helpers: { section: function(name, options){ if(!this._sections) this._sections = {}; this._sections[name] = options.fn(this); return null; } } Then, in your layout, you can … Read more
You’d have to loop 2 times: {{#each userSurvey}} {{#each this}} {{ this }} {{/each}} {{/each}}
The code is wrapped in an IIFE (Immediately Invoked Function Expression), which means the function is executed immediately. That’s what the following means: (function x() { console.log(‘hello’); })(); You can also do: (function() { console.log(‘hello’); }()); IIFEs are commonly used to create a “private” scope for a bit of code so that it plays nice … Read more
You should use pre-compiled client templates. They are faster executing and allow you to use the same template language on the server and client. Install handlebars globally npm install handlebars -g Precompile your templates handlebars client-template1.handlebars -f templates.js Include templates.js <script src=”https://stackoverflow.com/questions/10037936/templates.js”></script> Execute the template var html = Handlebars.templates[“client-template1”](context); https://stackoverflow.com/a/13884587/8360
The way I understand it, the way they break down is like this: “render” gives you an entire view/controller/template context of its own to work with. An example will be a top navigation that includes dynamic pieces. The content will be maintained within a TopNavController and inserted into the application template using “render” “partial” will … Read more
You are right, Handlebars and Angular together would be pretty useless. Handlebars and Angular are completely different things. Handlebars is a template engine. You write a fancy templatey-string, give it a JSON object, and it renders out HTML from the data. There’s no data-binding, no updating, it’s just a once-off render. AngularJS is an HTML … Read more
You should add parentheses around the embedded helper invocation: {{#if (itemSelected “SomeItem”)}} <div>This was selected</div> {{/if} I did experiments and verified that it just works. Not sure if it’s mentioned in the Handlebars documentation. I learned the trick from the examples of handlebars-layouts.
Create a Handlebars helper in one of the client-loaded JavaScript files in your project: Template.registerHelper(“log”, function(something) { console.log(something); }); And then call it in your template: {{log someVariable}} You can log the current context with simply {{log this}}. (Note that in Meteor before version 0.8, or in pure Handlebars outside of a Meteor app, replace … Read more
