Hear i am trying to add location in bangalore tab i am addling mumbai location and in delhi tab i want to add one more material location but the same form is coming in the next tab

What is obviously on your code is that you have space here in a line:
<%= l.location_name %>
as you can note l .location_name can you remove the space?

How to modify the value of an input in spree commerce cart

I have the following cart view that i addapted with bootstrap.
<div class="row line_item">
<div class="col-md-4 cart-item-image" data-hook="cart_item_image">
<% if variant.images.length == 0 %>
<%= link_to small_image(variant.product), variant.product %>
<% else %>
<%= link_to image_tag(variant.images.first.attachment.url(:product)), variant.product %>
<% end %>
</div>
<div class="col-md-4 cart-item-image" data-hook="cart_item_description">
<h4><%= link_to line_item.name, product_path(variant.product) %></h4>
<%= variant.options_text %>
<% if line_item.insufficient_stock? %>
<span class="out-of-stock">
<%= Spree.t(:out_of_stock) %> <br />
</span>
<% end %>
<span class="line-item-description" data-hook="line_item_description">
<%= line_item_description_text(line_item.description) %>
</span>
</div>
<div class="col-md-1 cart-item-price" data-hook="cart_item_price">
<%= line_item.single_money.to_html %>
</div>
<div class="col-md-1 cart-item-quantity" data-hook="cart_item_quantity" valign="center">
<%= item_form.number_field :quantity, min: 0, class: "form-control line_item_quantity", size: 5 %>
</div>
<div class="col-md-2">
<div class="cart-item-total" data-hook="cart_item_total">
<%= line_item.display_amount.to_html unless line_item.quantity.nil? %>
</div>
<div class="cart-item-delete" data-hook="cart_item_delete">
<%= link_to content_tag(:span, '', class: 'glyphicon glyphicon-minus-sign'), '#', class: 'delete', id: "delete_#{dom_id(line_item)}" %>
</div>
</div>
</div>
and the following coffeescript that goes along with it
Spree.ready ($) ->
if ($ 'form#update-cart').is('*')
($ 'form#update-cart a.delete').show().one 'click', ->
($ this).parents('.line-item').first().find('input.line_item_quantity').val 0
($ this).parents('form').first().submit()
false
($ 'form#update-cart').submit ->
($ 'form#update-cart #update-button').attr('disabled', true)
Now the delete button does not work with this cart html ( while it is working with the original view a following)
<div style="margin-top: 35px;">
<div class="row">
<tr class="line-item">
<td class="col-md-4 cart-item-image" data-hook="cart_item_image">
<% if variant.images.length == 0 %>
<%= link_to small_image(variant.product), variant.product %>
<% else %>
<%= link_to image_tag(variant.images.first.attachment.url(:small)), variant.product %>
<% end %>
</td>
<td class="col-md-4 cart-item-description" data-hook="cart_item_description">
<h4><%= link_to line_item.name, product_path(variant.product) %></h4>
<%= variant.options_text %>
<% if line_item.insufficient_stock? %>
<span class="out-of-stock">
<%= Spree.t(:out_of_stock) %> <br />
</span>
<% end %>
<span class="line-item-description" data-hook="line_item_description">
<%= line_item_description_text(line_item.description) %>
</span>
</td>
<td class="col-md-1 lead text-primary cart-item-price" data-hook="cart_item_price">
<%= line_item.single_money.to_html %>
</td>
<td class="col-md-1 cart-item-quantity" data-hook="cart_item_quantity" valign="center">
<%= item_form.number_field :quantity, min: 0, class: "form-control line_item_quantity", size: 5 %>
</td>
<td class="col-md-1 lead text-primary cart-item-total" data-hook="cart_item_total">
<%= line_item.display_amount.to_html unless line_item.quantity.nil? %>
</td>
<td class="col-md-1 cart-item-delete" data-hook="cart_item_delete">
<%= link_to content_tag(:span, '', class: 'glyphicon glyphicon-minus-sign'), '#', class: 'delete', id: "delete_#{dom_id(line_item)}" %>
</td>
</tr>
</div>
</div>
It seems to me that the coffeescript should work in both cases!
What am i missing after i modify the view ? It seems to me that the coffeescript should perform the search in both cases...

It doesn't look like you've done anything wrong when it comes to keeping the markup for the javascript the same. My guess would be that Spree.ready ($) -> isn't actually firing. That could be caused by you removing javascript files during your view customization by accident. You should try checking your web developer console to see if there are any javascript errors like Spree not being defined or something like that.

dynamically add div in rails

I want make <div class="row">.
if <div class="col-md-4"> is three or more,
I want make <div class="row">.
Because I use twitter bootstrap grid view.
My View is
<% #account_products.order(created_at: :desc).each do |product| %>
<div>
<div class="col-md-4">
<div = "icons-right">
<span class = "icons-right">
<%= link_to image_tag("like.png", size: "30"),
line_items_path(product_id: product),
:class => "cart_image", method: :post %>
<button class="btn btn-default btn-sm dropdown-toggle" type="button" data-toggle="dropdown" aria-expanded="false">
<span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu">
<!-- edit_product_path, product.id로 했으나 id값을 전달하지 않았다. -> 전달은 매개변수로 ! -->
<li role="presentation"><%= link_to "edit", edit_product_path(product.id) %></li>
<li role="presentation"><%= link_to "destory", product, method: :delete %></li>
</ul>
</span>
</div>
<div class="fixed-size-image">
<a href = "<%= product.image_url %>" target = "blank" >
<%= image_tag(product.item.url) if product.item? %>
</a>
</div>
<div class = "brand">
<%= product.brand %>
</div>
<div class = "description">
<%= product.title %>
</div>
<div class = "price">
<%= product.price %>
</div>
<!-- line_item_path -> line_items_path class="btn btn-primary btn-lg active -->
<!-- like.png -->
</div>
</div>
<% end %>

If I understand correctly, you're trying to output a <div class="row"> for every three columns, is that right?
There are two ways to do it:
<% #account_products.order(created_at: :desc).each_with_index do |product, i| %>
<% if i%3 == 0 %>
<div class="row">
<% end %>
... (The rest of your code)
<% if i%3 == 0 %>
</div>
<% end %>
<% end %>
Or:
<% #account_products.order(created_at: :desc).in_groups_of(3) do |product_group| %>
<div class="row">
<% product_group.compact.each do |product| %>
... (The rest of your code)
<% end %>
</div>
<% end %>
---edit---
As requested, jQuery solution:
var a = $('.col-md-4');
while(a.length) {
$(a.splice(0,3)).wrapAll("<div class='row' />")
}

Ruby on Rails jQuery: Toggle not working

I am trying to create a button that shows/hides a div. It seems relatively easy, but whenever I click this button, it just does a refresh, and when I keep clicking it, it hides most of my page. Here is what I have so far. Also, I dont know if it matters but I am using foundation for most of the css
application.js
$(function() {
$(document).foundation();
});
$(document).ready(function() {
$('#message_button').click(function() {
$("#messages").toggle();
});
});

I am trying to an $().click action to the link_to button with id "message_button". Whenever this button/link is clicked, I want it to show/hide the "messages" div.
I am new to jQuery, rails, and foundation, so I left most of the code just in case anything was important. But I marked the message_button and the message div to help you better find it.

2 problems:
It looks to me as though you have a bad case of the "multiple IDs"!
You are not preventing the default behaviour of the link. (so when you click it, the page refreshes or navigates away)
Problem #2 is easy: call preventDefault() (usage example below).
Problem #1 is a little trickier...
You are creating <li> content within a loop, inside each of those <li> tags you have elements with the IDs #messages and #message_button. Multiple instances of an ID on the same page is not allowed. If you want, you can use classes instead of ids as you can have multiple instances of a class.
However, switching from IDs to Classes won't fix your problem, as if you use classes you'll just be toggling ALL messages when any message button is clicked.
Referring to this question here, you can easily get the index of the loop in your rails template:
<% #active.each do |job, index| %>
Your template/html code here
<% end %>
This exposes a new variable, index which you can use to decorate each of your messages and buttons with an index value to then specify which message you wish to show.
Note: I'm not sure if this is the best approach, but this should work. It's been a while since I've used Rails, so there might be errors. I've included the code below just to demonstrate the possible solution:
application.js:
$(function() {
$(document).foundation();
});
$(document).ready(function() {
//NOTE that I am selecting on a class here
$('.message_button').click(function(e) {
//You also need to prevent the default behaviour of
//the link. That is why the page keeps refreshing.
e.preventDefault();
//get the index value I appended to this elements ID
var msgButtonIndex = $(this).attr("id").replace("message_button_","");
//select and toggle the respective message
$("#messages_" + msgButtonIndex).toggle();
});
});
