Hai
Thank you for the reply.
here is my sample code of view
<table width="100%" border="1">
<tr><td colspan="6" align="center"><h3>User list</h3></td>
</tr>
<tr>
<th>Name</th>
<th>User Name</th>
<th>Address</th>
<th> Country</th>
<th>Language</th>
<th> <%= submit_tag "Select All", :onclick=>"return check_all()" %>
</th>
</tr>
<% count = 0 %>
<%= form_tag :controller=>"user",:action=>"list_users"%>
<% for user in @users %>
<% count = count + 1%>
<tr>
<td align="center"><%=link_to
user.name,:controller=>"User",:action=>"edit", :id=>user.id %></td>
<td align="center"><%= user.username %></td>
<td align="center"><%= user.address %></td>
<td align="center"><%= user.country.name %></td>
<td align="center"><%= user.language.language %>
<td> <%= check_box_tag "user_status"+count.to_s,user.id%>
</tr>
<% end %>
<%= hidden_field_tag "h_id" ,count %>
<tr><td colspan="6" align="center">
<%= will_paginate @users %><br>
<%= submit_tag "Approve", :controller=>"user"
,:action=>"list_users",:class=>"test"%>
</table>
and in my controller I tried this one
def list_users
if !(params[:search].blank? and params[:country_id].blank?)
if request.post? and params[:commit] == "Search"
@users =
User.search(params[:search],params[:country_id],params[:page])
else
@users = User.paginate :page=>params[:page],:per_page => 2
end
else
@users = User.paginate :page=>params[:page],:per_page => 2
end
if @users.blank?
flash[:notice] = 'No Records Found.'
end
if request.post? and params[:commit] == "Approve"
params[:user_status].each do |ln|
@user = User.find(ln)
@user.update_attribute(:user_status,1)
end
end
end
Now if selected users separately(not by using the "Select All"
button) the status of the selected users are changing. But the "Select
All" button is not working. ie when clicking on the "Select All" button
only the first one in the list is selecting
and in my javascript i wrote
function check_all() {
var count = document.getElementById('h_id').value;
for(i=1;i<=count;i++){
document.getElementById('user_status'+i).checked = true
}
return false;
}
what is the problem with this one? pls give suggestion.
