this is my table:
<tbody>
<% #productos.each do |producto| %>
<tr>
<td><%= producto.codigo %></td>
<td><%= producto.descripcion %></td>
<td><%= producto.stock %></td>
<td><%= button_to '+', "#", method: :get,class: 'btn btn-info btn-sm btn_add' %></td>
</tr>
<% end %>
</tbody>
On button click i want to get the value of |producto| (each row)in JAvascript and send to other table in the same view OR the right way is to get the value from td ? example:
<td><%= producto.codigo %></td> //in this case how i get the value of this td?
Using Javascript or Jquery. thanks
First add id in every td al follows
<tbody>
<% #productos.each do |producto| %>
<tr>
<td id="code-<%= producto.codigo %>"><%= producto.codigo %></td>
<td id="des-<%= producto.codigo %>"><%= producto.descripcion %></td>
<td id="stock-<%= producto.codigo %>"><%= producto.stock %></td>
<td><%= button_to '+', "#", method: :get,class: 'btn btn-info btn-sm btn_add' %></td>
</tr>
<% end %>
</tbody>
Now in you button add an attribute data-id like this
<button class="btn btn-info btn-sm btn_add" data-id="<%= producto.codigo %>" type="button">Click</button>//I don't know about Rails so do this code in your language.
Now The jQuery is given below...
<script>
$(document).on('click','btn_add',function(){
id = $(this).data('id'); //get the clicked button's id
var code = $('#code-'+id).html(); //get the code of that row
var des = $('#des-'+id).html(); //get the description of that row
var stock = $('#stock-'+id).html(); //get the stock of that row
alert('Code - '+code+'<br> Description - '+des+'<br>Stock - '+stock);
});
</script>
1- pass all the variable which you want in js code block on click event
<td><%= button_to '+', "#", method: :get,class: 'btn btn-info btn-sm btn_add', :onclick => "get_current_producto(this, '<%=producto.codigo%>', '<%=producto.descripcion%>', '<%=producto.stock%>');" %></td>
2- get all variables here and
<script type="text/javascript>
function get_current_producto(elm, codigo,descripcion, stock ){
//code goes here
//console.log(codigo);
alert(descripcion);
};
</script>
here elm is button element on which click event is called you can get id or class of that button element by using elm

I am creating a table of barcodes using JSBarcode and a for-each loop. The problem is that the value of the barcodes are always the same (for some reason they are all the value of the last element in the loop).
Here is my code:
<tbody>
<% lineitemObj.forEach(function(obj) { %>
<tr>
<td><%= obj.id %></td>
<td><%= obj.drawing_num %></td>
<td><%= obj.description %></td>
<td><%= obj.qty %></td>
<td>
<svg id="barcode"></svg>
<script>
var ln = '<%= obj.id %>'
JsBarcode("#barcode", ln);
</script>
</td>
</tr>
</tbody>
How do I get the barcodes to properly represent the unique id of each object?
Try it
JsBarcode("#barcode", "12345", {format: "pharmacode"});
I want to know how to apply a color in .ejs file. Here is the code.
<% resultList.forEach(function(item, index){ %>
<tr>
<td><%= item.function %></td>
<td><%= item.value %></td>
<td><%= item.content %></td>
</tr>
<% }); %>
if(item.value == false) //I want to apply red color
How can I do that? Thank you.
Would something like this work?
<% resultList.forEach(function(item, index){ %>
<tr>
<td><%= item.function %></td>
<% if (item.value === false) { %>
<td style='color:red;'><%= item.value %></td>
<% else %>
<td><%= item.value %></td>
<% } %>
<td><%= item.content %></td>
</tr>
<% }); %>
Note personally I think this is ugly. I would try to keep more code out of template side and would also use a CSS class for the coloring, but it was easier to illustrate this way.
I have one looping Dates and table content.
I want to display table content based on Dates. How's it possible please help me.
index.html.erb
<% #batches.each do |batch| %>
<tr>
**<td class = "pie" id ="demo"> <i class="fa fa-plus-circle"></i>
<%= batch.date.strftime("%Y-%m-%d") if !batch.date.nil? %></td>**
<td><%= batch.purchase_center.name.to_s if !batch.purchase_center.nil? %></td>
<td><%= batch.plant.name.to_s if !batch.plant.nil?%></td>
<td><%= batch.species.name.to_s if !batch.species.nil? %></td>
<td><%= batch.batch_number %></td>
<td><%= batch.total_quantity %></td>
<td><%= batch.calculated_yeild %></td>
<td><%= link_to '<i class="fa fa-users"></i>'.html_safe, "#", :class => "addsupplier", :id => "#{batch.serial_id}" %></td><td><%= link_to '<i class="fa fa-trash-o"></i>'.html_safe, batch, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<tr class="<%= batch.serial_id %>" style="display:none">
<%= render :partial => "batch_counts/form", locals: {id: "#{batch.serial_id}"} %>
</tr>
**<td id ="two" style="display:">
Microsoft Corporation
Microsoft Corporation
</td>**
<% end %>
<script type="text/javascript">
$('#demo').click(function(){
$('#two').toggle();
});
</script>
I highlighted with star marks i.e. id = demo and id =two.
i have different dates and different message. So i want to display it on which date is having which message.
Based on dates display message.
Give a common class to each of them. Say, date-alert:
<td class="pie date-alert" id="demo"> <i class="fa fa-plus-circle"></i>
<%= batch.date.strftime("%Y-%m-%d") if !batch.date.nil? %></td>
<td id="two" style="display:" class="date-alert">
Microsoft Corporation
Microsoft Corporation
</td>
And then upon clicking it, you can execute like this:
$(".date-alert").click(function () {
// the current td is this
});
I have an array of Pet instances and each of them have a name, type, sex and size, etc... I'd like to iterate through this collection of Pet instances and display the each one by one.
This is what I have so far:
<% #pets.each do |pet| %>
<table class="table">
<thead>
<tr>
<th>Name</th>
<th>Type</th>
<th>Sex</th>
<th>Age</th>
<th>breed</th>
<th>Size</th>
<th>Picture</th>
<th>Description</th>
<th>Shelter_id</th>
<th>Shelter</th>
<th>Phone</th>
<th>Email</th>
<th>City</th>
<th>Zip</th>
<th>Like</th>
</tr>
</thead>
<tbody>
<tr>
<td><%= pet.name %></td>
<td><%= pet.species %></td>
<td><%= pet.sex %></td>
<td><%= pet.age %></td>
<td><% pet.breeds.each do |breed| %>
<li><%= breed.name %></li>
<%end%>
</td>
<td><%= pet.size %></td>
<td><%= image_tag pet.picture %></td>
<td><%= pet.description %></td>
<td><%= pet.shelter_id %></td>
<% shelter = Shelter.find(pet.shelter_id)%>
<td><%= shelter.name %></td>
<td><%= shelter.phone %></td>
<td><%= shelter.email %></td>
<td><%= shelter.city %></td>
<td><%= shelter.zip %></td>
<td><%= form_for pet, :url => { :controller => "favorite_pets", :action => "create" }, :html => {:method => :post} do |f| %>
<%= f.text_field :id %>
<%= f.submit %>
<% end %>
</td>
</tr>
</tbody>
</table>
<%end%>
So now, I need two thinks.
1st
When a user clicks the submit button (<%= f.submit %>) to send a POST request i do not want the page to reload nor to redirected me to another page. I looked around and it seems like :remote => true included in the form_for would do the trick but i'd need more help with that.
2nd
I'd like to control the iterating through #pets so that only the first one is displayed pet[0] and every time I click on the <%= f.submit %> button not only does it not reload the page but it displays the next index in the array pet[1]
I think I need to set up a sort of counter which would increment the index of the pet array every time a user click on the <%= f.submit %> button.
Any guiding thoughts?
If I were to do this I would use some javascript. So your submit button turns into more of an "Add Button" it doesn't actually submit anything. It would just add that object (in your case the pet, along with its info) to a javascript array as well as display the new object (again the pet along with the info) on the window. Then create another button to actually submit all the pets. (The javascript array)
I'm trying to make my table sortable (drag and drop) using jQuery, the problem I'm having is saving the new sorted table and then publishing it to other users or when the browser is refreshed.
I'm using:
gem 'acts_as_list'
Rails 3.2.17
ruby 1.9.3p484
Is there a better way of doing this?
my sort and show method on my controller
def sort
#episodes = current_user.episodes_for(#show).each do |episode|
episode.position = params['episode'].index(episode.id.to_s) + 1
episode.save
end
render :nothing =>true
end
def show
#episodes = current_user.episodes_for(#show)
#episodes.order('episode.position ASC')
#episode = #episodes.where(id: params[:id]).first
end
My Javascript
<script>
$(window).load(function() {
$("#sortthis").sortable({
axis: 'y',
placeholder: 'ui-state-highlight',
cursor: 'move',
dropOnempty: false,
scroll: true,
opacity: 0.4,
update: function(event, ui){
var itm_arr = $("#sortthis").sortable('toArray');
var pobj = {episodes: itm_arr};
$.post("/episodes/sort", pobj);
}
});
});
</script>
The table I wanna sort in views:
<tbody id='eps'>
<tr>
<th>Title</th>
<th>#</th>
<th>Season</th>
<th>Download?</th>
<th>Shared?</th>
<th>Length</th>
<th>Status</th>
<th></th>
</tr>
<% for episode in #episodes %>
<tr>
<td id="eps_<%= episode.id %>", width="20%"><%=h episode.title %></td>
<td id="eps_<%= episode.id %>"><%=h episode.number %></td>
<td id="eps_<%= episode.id %>"><%=h episode.season %></td>
<td id="eps_<%= episode.id %>"><%=h episode.is_downloadable %></td>
<td id="eps_<%= episode.id %>"><%=h episode.shared_with_dev %></td>
<td id="eps_<%= episode.id %>"><%=h episode.length %></td>
<td>
<% if episode.video %>
<%= link_to 'Replace Video', new_show_episode_video_path(episode.show, episode) %>
<% else %>
<%= link_to 'Upload Video', new_show_episode_video_path(episode.show, episode) %>
<% end %>
</td>
<td>
<%= link_to "View", [episode.show, episode] %>
<%= link_to "Edit", edit_show_episode_path(episode.show, episode) if permitted_to? :update, episode %>
<%= link_to "Delete", show_episode_path(episode.show, episode), :confirm => 'Are you sure?', :method => :delete if permitted_to? :delete, episode %>
</td>
</tr>
<% end %>
any help will be greatly appreciated!
I figured it out, made the following changes:
Views:
<tr id="<%= episode.id %>">
and new controller
def sort
Episode.all.each do |e|
if position = params[:episodes].index(e.id.to_s)
e.update_attribute(:position, position + 1) unless e.position == position + 1
end
end
render :nothing => true, :status => 200
end
finally added this to my model:
acts_as_list
default_scope order('position')
let me know if anyone's having similar issues.
