meteor-blaze

问题 I kindly need a support. I have written a pagination following a YouTube tutorial, which works fine with the exception of when going backwards again. It has only 2 buttons, previous and next , when the next button is clicked it works fine but the previous button only go backwards once. Let's say I have 20 records in the collections paginated to display 5 at a time, the next button could go to the end to the fourth page but the previous button would not go pass one step backwards. Please what

问题 With meteor updates up to 0.8 my old code stopped working. Handlebars.registerHelper('getTemplate', function(id, context) { return Template[id](context); }); <template name="main"> .... {{{getTemplate templateName context}}} .... </template> //somewhere in other template Template.main.context = {name:value}; This way I was able to render a custom template with custom data. Now I can't find the way to pass context to the dynamic template. With blaze both templateName and context is undefined.

问题 Is there a way to do logic operation in {{#if}} statement? I was hoping for something like: {{#if A && B}} some html {{/if}} I couldn’t find documentation about logic in blaze, so I guess it’s not supported. I just wanted to be sure. Sorry for the rather stupid question... 回答1: As Billy Bob suggests, you would need parameterized helpers. Here are two global helpers you could use in any context: Template.registerHelper('and',(a,b)=>{ return a && b; }); Template.registerHelper('or',(a,b)=>{

问题 What is the best way to get and select values from a dropdown list (and also in radio) in Meteor. I have created a helper: Template.categories.helpers({ categories: ["facebook", "news", "tv", "tweets"] }); and in html ... <select class="form-control" id="category"> {{> categories}} </select> ... <template name="categories"> <option disabled="disabled" selected="selected">Please Select</option> {{#each categories}} <option value="{{this}}">{{this}}</option> {{/each}} </template> In case of

问题 I'm trying to prevent a template helper to be rerun when it is unnecessary. I made a simple application to illustrate this behavior: Let's say I want to display some items that contain only a title and a description. <template name="Tests"> {{#each items}} {{> TestsItems}} {{/each}} </template> <template name="TestsItems"> <div class="title">{{title}}</div> <div class="description">{{description}}</div> </template> I have autopublish enabled. Template.Tests.helpers({ items: function () {

问题 I'm confused about how _uihooks works. Check out the below code: home.html <template name="homePage"> <section id="home-page"> <div class="container"> <h1>Thought of the day:</h1> <div id="totd"> <span>{{thought}}</span> </div> </div> </section> </template> home.coffee timer = 0 Template.homePage.rendered = -> this.find('#totd')._uihooks = insertElement: (node, next) -> console.log 'Inserted' removeElement: (node) -> console.log 'Removed' Session.set 'randThought', Random.choice thoughts

问题 I have homepage, contact page, and several other product related pages in my app. The goal is to apply a background image to ONLY specifc routes: /homepage and /contact . If user navigates away from either route, apply some css change. I am hacking this together now with a helper on my homepage, like so: Template.homepage.rendered = function () { var route = Router.current(); if ( route.path == '/' ) { document.body.className = "showBackgroundImage"; } }; Partial win here, since this will
