Jquery Auto Tab for Phone fields

Its a good thing, If  we implement autotab for telephone fields. It would be more nice. There are many Jquery plugins. But here I created my own simple autotab with a jquery function.

Here I'm explaining with rails application

Add onKeyup javascript event autotab() to your text fields in which you want to implement autotab

Then View should look like the following

<%=text_field_tag :isd, nil, :maxlength => 3, :onKeyup => "autotab(this)" %>
<%=text_field_tag :std, nil, :maxlength => 5, :onKeyup =>"autotab(this)"%>
<%=text_field_tag :num, nil, :maxlength => 12 %>

Then add the js function to your application.js

function autotab( field ){
if(field.getAttribute&&field.value.length==field.getAttribute("maxlength")){
    $(field).next('input').focus();
  }
}

This will do the autotab thing.
For any query please comment on the same thread. Thank you.

Rails Kaminari - Ajax pagination

Here is a simple way to implement AJAX pagination using  Kaminari gem. Suppose, We are having a Product Model with fields id and name. So, In the ProductsController , def index   @products =  Product.all.page(params[:page]).per(params[:per])    respond_to do |format|       format.js       format.html     end end in view file index.html.haml   #products     = render 'products'   #paginator     = paginate @products, :remote => true And create _products.html.haml (this will be rendered from index) with content   %table     @products.each do |product|      %tr        %td= product.name Finally, We have to create one more  file _index.js.haml with content $('#products').html("#{escape_javascript(render 'products')}"); $('#paginator').html("#{escape_javascript(paginate(@products, :remote => true)) }"); This post may help you.

Ruby's class_eval & instance_eval. Is it that confusing?

Image
We can do class_eval & instance_eval using following syntax, In this example, class_eval? method can be accessed my any objects of the String class. Where as instance_eval? method can be accessed by only String class.  More clearly, class_eval creates instance methods, but instance_eval creates class methods or it can be applied to only one object at a time. [3] pry(main)> String.class_eval? NoMethodError: undefined method `class_eval?' for String:Class Did you mean?  class_eval from (pry):3:in `<main>' [4] pry(main)> String.instance_eval? => true [5] pry(main)> String.new.class_eval? => true my_string = "This is a string" For example you can simply do like below as any string is an object of String Class [5] pry(main)>  my_string .class_eval? => true But you can not do  [7] pry(main)> my_string.instance_eval? NoMethodError: undefined method `instance_eval?' for "This is a string":String
