Yesterday I was working on one of our portal (It's in Ruby on Rails and we have used quite alot jquery as well). Was integrating a nice Photo Gallery plugin on one of the page. Applcation is having many pages. Every page has some different behaviour and we have different jquery calls for that as per need. For a performant application, we always want to avoid any unwanted calls to different methdods/functions. In my case, as I mentioned earlier I wanted to show Photo Gallery on a page and photo gallery loads as soon as page is loaded. Gallery

Easy way to create a numeric input, which accepts only numbers (i.e. 0-9 and no other characters). app/components/numeric-input.js import Ember from 'ember'; export default Ember.TextField.extend({ tagName: "input", type: "number", attributeBindings: [ "name", "type", "value", "maxlength", "id" ], keyDown: function(e) { var key = e.charCode || e.keyCode || 0; // allow enter, backspace, tab, delete, numbers, keypad numbers, home, end only. return ( key === 13 || key === 8 || key === 9 || key === 46 || (key >= 35 && key = 48 && key = 96 && key And in your template, call it as {{numeric-input value=mobilePhone name="mobilePhone" id="mobile" maxlength="8" }} As the number input displays up

To follow DRY, we need to make rails locales available in javascript. One way to do it is to declare a global variable and have all locales saved to it as Javascript Object. This is what we did in our project: Added following code in application layout: For HAML - window.I18n = #{I18n.backend.

Why we need YAML parser. As long as we are working in rails we will hardly face a situation, where we have to parse the YAML files in javascript.However when we are planning to work on node.js OR tideSDK where javascript is the heart of everything, then in that case we need something to parse the configs and then writing to configs if necessary. There are many parser available to read the YAML. But there are very few which does the reverse good. I found just two plugins like that. One plugin was bit confusing and it had
