I want to access the first item of an array inside a meteor template, I'm using this syntax : <p>{{array[0]}}</p> However it doesn't seem like it's working. I don't want to iterate through values using {{#each}} , just pick the first one from the array. This is just a problem of syntax, the correct one is the following : <p>{{array.[0]}}</p> Notice the . dot between the array property and the brackets (array indexing) notation ? Here is the (hidden) docs for this : https://github.com/meteor/meteor/wiki/Using-Blaze#dotted-helpers-with-numeric-indices 来源： https://stackoverflow.com/questions

I am from AngularJS background, recently start learning Meteor. In AngularJS, I may have something like: <div ng-repeat="person in persons | filter:search"> <h4>{{person.name}}</h4> <b>{{person.age}}</b> </div> search object can be bound (2-way bound) to HTML textbox. Whenever the textbox changed, the filter will be automatically updated. How to do so in Meteor? I am not familiar with AngularJS, but here is an example of how you would accomplish this with Meteor. This example shows a list of persons, along with an HTML number input that you can use to filter by age the displayed list. client

I have tried this a couple different ways and they both behave the same way (see below for code). I'm using a spacebars if condition (and tried using a helper as well) to check if the user is logged in, then display login/sign up links if they aren't. If they are, hide them. What I noticed is that on the initial page load (if they navigate back from a different site), the login/sign up links show quickly before hiding (if the user is still logged in). Is there a way to insure that no elements render in the view if the condition is false? It seems to me that it should check before the view

I'm having trouble with a callback after the #each has finished. I have a template named "content": <template name="content"> {{#if Template.subscriptionsReady}} {{#each currentData}} <div data-cid="{{this._id}}"></div> {{/each}} {{else}} Loading... {{/if}} </template> At first I wait for a subscription, when this is available, I iterate through my Collection with {{#each}} and append the div . What I need is a sort of callback for when the for-each loop is done (in other words DOM ready). Template.content.onRendered() -> triggers to early I also tried appending an image after the {{each}} and

Until version 0.8 it was possible to use the regular Handlebars way for defining iterative block helpers such as the popular each_with_key , defined, e.g., here as follows: Handlebars.registerHelper("each_with_key", function(obj, fn) { var context, buffer = "", key, keyName = fn.hash.key; for (key in obj) { if (obj.hasOwnProperty(key)) { context = obj[key]; if (keyName) { context[keyName] = key; } buffer += fn(context); } } return buffer; }); This no longer works in 0.8, and neither the migration guide nor the spacebars documentation show an example for this. Given that block helpers are now
