  • finding links that are hyper-links in jQuery

    - by Jacob Lowe
    Im trying to take a link either when clicked or hover over be able to grab the attribute href and tell if its a hyper-link or not. Also i want it to be able to tell me if its a hyper-link to my own site. Plus various other filters. The main purpose for this is so that when a internal link is clicked it will tell ajax to grab the content, alot of my links are generated (via wordpress)so I can't modify them too much. Another purpose for this is so i can also make all external links open on a new window. I have a solution that works on a simple test page but when i put into a working page it breaks. I know i am probably making this harder then it should be. Here is my code $(function(){ $('a').live('click', function(){ var x = $(this).attr('href'); $(this).parent('div').append('<div id="test">' + x +'</div>'); $('#test:contains("http")').css('color', 'red'); $('#test:contains("sitename")').css('color', 'black'); $('#test:contains("admin")').css('color', 'red'); if($('#test').css('color') == 'red'){ alert('external link'); $('#test').remove(); return true; }else{ alert('external link'); $('#test').remove(); return false; } }); }); thanks for you help

  • Displaying images in webpage without src URL

  • Rails creating users, roles, and projects

    - by Bobby
    I am still fairly new to rails and activerecord, so please excuse any oversights. I have 3 models that I'm trying to tie together (and a 4th to actually do the tying) to create a permission scheme using user-defined roles. class User < ActiveRecord::Base has_many :user_projects has_many :projects, :through => :user_projects has_many :project_roles, :through => :user_projects end class Project < ActiveRecord::Base has_many :user_projects has_many :users, :through => :user_projects has_many :project_roles end class ProjectRole < ActiveRecord::Base belongs_to :projects belongs_to :user_projects end class UserProject < ActiveRecord::Base belongs_to :user belongs_to :project has_one :project_role attr_accessible :project_role_id end The project_roles model contains a user-defined role name, and booleans that define whether the given role has permissions for a specific task. I'm looking for an elegant solution to reference that from anywhere within the project piece of my application easily. I do already have a role system implemented for the entire application. What I'm really looking for though is that the users will be able to manage their own roles on a per-project basis. Every project gets setup with an immutable default admin role, and the project creator gets added upon project creation. Since the users are creating the roles, I would like to be able to pull a list of role names from the project and user models through association (for display purposes), but for testing access, I would like to simply reference them by what they have access to without having reference them by name. Perhaps something like this? def has_perm?(permission, user) # The permission that I'm testing user.current_project.project_roles.each do |role| if role.send(permission) # Not sure that's right... do_stuff end end end I think I'm in over my head on this one because I keep running in circles on how I can best implement this.

  • Nested and complicated select statement

    - by Selase
    What i want to do here is simple...display an ivestigators ID and him corresponding name... That can be easily done from the users table by selecting based on the user type. However i want to select only some type of investigators. The analogy here is investigators are assigned to an exhibit for them to investigate. One investigator can be assigned to a maximum of 3 cases only. Now during the assigning of investigators, i want to write a select statement that would retrieve only investigatorID's that have been assigned to less than or equal to 2 cases. I have included exhibit and users table that shows sample data below. Now i sort of have an idea that i will have to first of all pick out all the investigators by their ID from the users list and then filter them through the exhibit table by dropping those assigned to 3 cases and leaving just those with two cases. then afterwards i use this IDs to select the Investigators name. the big questions is how do i write the statement??

  • Nested model form with collection in Rails 2.3

    - by kristian nissen
    How can I make this work in Rails 2.3? class Magazine < ActiveRecord::Base has_many :magazinepages end class Magazinepage < ActiveRecord::Base belongs_to :magazine end and then in the controller: def new @magazine = Magazine.new @magazinepages = @magazine.magazinepages.build end and then the form: <% form_for(@magazine) do |f| %> <%= error_messages_for :magazine %> <%= error_messages_for :magazinepages %> <fieldset> <legend><%= t('new_magazine') %></legend> <p> <%= f.label :title %> <%= f.text_field :title %> </p> <fieldset> <legend><%= t('new_magazine_pages') %> <% f.fields_for :magazinepages do |p| %> <p> <%= p.label :name %> <%= p.text_field :name %> </p> <p> <%= p.file_field :filepath %> </p> <% end %> </fieldset> <p> <%= f.submit :save %> </p> </fieldset> <% end %> problem is, if I want to submit a collection of magazinepages, activerecord complaints because it's expected a model and not an array. create action: def create @magazine = Magazine.new params[:magazine] @magazine.save ? redirect_to(@magazine) : render(:action => 'new') end

  • Rails 3 Nested Forms

    - by Mike
    I have a Person model and an Address Model: class Person < ActiveRecord::Base has_one :address accepts_nested_attributes_for :address end class Address < ActiveRecord::Base belongs_to :person end In my people controller I have @person.build_address in my new action. My forms builds correctly. The problem is that when I submit the form, a person record and an address record is created but they aren't linked via the address_id column in the Person table. Am I missing a step in the controller? Thanks! New Action UPDATE def new @person = Person.new @person.build_address respond_to do |format| format.html # new.html.erb format.xml { render :xml => @person } end end Form Code UPDATE <%= form_for(@person) do |f| %> <% if @person.errors.any? %> <div id="error_explanation"> <h2><%= pluralize(@person.errors.count, "error") %> prohibited this person from being saved:</h2> <ul> <% @person.errors.full_messages.each do |msg| %> <li><%= msg %></li> <% end %> </ul> </div> <% end %> <div class="field"> <%= f.label :first_name %><br /> <%= f.text_field :first_name %> </div> <div class="field"> <%= f.label :last_name %><br /> <%= f.text_field :last_name %> </div> <div class="field"> <%= f.label :email %><br /> <%= f.text_field :email %> </div> <div class="field"> <%= f.label :telephone %><br /> <%= f.text_field :telephone %> </div> <div class="field"> <%= f.label :mobile_phone %><br /> <%= f.text_field :mobile_phone %> </div> <div class="field"> <%= f.label :date_of_birth %><br /> <%= f.date_select :date_of_birth %> </div> <div class="field"> <%= f.label :gender %><br /> <%= f.select(:gender, Person::GENDER_TYPES) %> </div> <div class="field"> <%= f.label :notes %><br /> <%= f.text_area :notes %> </div> <div class="field"> <%= f.label :person_type %><br /> <%= f.select(:person_type, Person::PERSON_TYPES) %> </div> <%= f.fields_for :address do |address_fields| %> <div class="field"> <%= address_fields.label :street_1 %><br /> <%= address_fields.text_field :street_1 %> </div> <div class="field"> <%= address_fields.label :street_2 %><br /> <%= address_fields.text_field :street_2 %> </div> <div class="field"> <%= address_fields.label :city %><br /> <%= address_fields.text_field :city %> </div> <div class="field"> <%= address_fields.label :state %><br /> <%= address_fields.select(:state, Address::STATES) %> </div> <div class="field"> <%= address_fields.label :zip_code %><br /> <%= address_fields.text_field :zip_code %> </div> <% end %> <div class="actions"> <%= f.submit %> </div> <% end %>

  • Nested <ul><li> navigation menu using a recursive Python function

    - by Alex
    Hi. I want to render this data structure as an unordered list. menu = [ [1, 0], [2, 1], [3, 1], [4, 3], [5, 3], [6, 5], [7,1] ] [n][0] is the key [n][1] references the parent key The desired output is: <ul> <li>Node 1</li> <ul> <li>Node 2</li> <li>Node 3</li> <ul> <li>Node 4</li> <li>Node 5</li> <ul> <li>Node 6</li> </ul> </ul> <li>Node 7</li> </ul> </ul> I could probably do this without recursion but that would be no fun. Unfortunately, I am having problems putting it all together. I don't have much experience with recursion and this is proving to be very difficult for me to build and debug. What is the most efficient way to solve this problem in Python? Thanks!

  • Multiple/nested "select where" with Zend_Db_Select

    - by DJRayon
    Hi there I need to create something like this: select name from table where active = 1 AND (name LIKE 'bla' OR description LIKE 'bla') The first part is easy: $sqlcmd = $db->select() ->from("table", "name") ->where("active = ?", 1) Now comes the tricky part. How can I nest? I know that I can just write ->orWhere("name LIKE ? OR description LIKE ?", "bla") But thats wron, because I need to dynamically change all the parts. The query will be built all the time the script runs. Some parts get deleted, some altered. In this example I need to add those OR-s because sometimes I need to search wider. "My Zend Logic" tells me that the correct way is like this: $sqlcmd = $db->select() ->from("table", "name") ->where("active = ?", 1) ->where(array( $db->select->where("name LIKE ?", "bla"), $db->select->orWhere("description LIKE ?", "bla") )) But that doesn't work (atleast I dont remember it working). Please. Can someone help me to find a object oriented way for nesting "where"-s

  • Nested pound sign problem

    - by Ray Buechler
    I'm having an issue when I try to nest pound signs in my ColdFusion code. I keep getting the following error message: Invalid CFML construct found on line 57 at column 26. ColdFusion was looking at the following text: # Here is the code: <cfloop index="i" from="1" to="12"> <cfset needRecord.setNeed#i#(#form["need#i#"]#) /> </cfloop> If I run the loop outside the cfset tag like this: <cfloop index="i" from="1" to="12"> needRecord.setNeed#i#(#form["need#i#"]#) </cfloop> The code runs and generates what I would like to generate within the cfset tag. Any idea what I'm doing wrong? Any help would be greatly appreciated.

  • Magento and unsetting a custom boolean attribute

    - by Spongeboy
    Hi, I've added an attribute to a customer address entity. Attribute setup code is as follows- 'entity_type_id'=>$customer_address_type_id, 'attribute_code'=>'signature_required', 'backend_type'=>'int', 'frontend_input'=>'boolean', 'frontend_label' => 'Signature required', 'is_global' => '1', 'is_visible' => '1', 'is_required' => '0', 'is_user_defined' => '0', I have then - added attribute to model\entity\setup.php added a HTML field on the edit form I am now getting the attribute saved to the database when the checkbox is checked. However, it is not being unset when checkbox is unchecked (I'm guessing due to checkbox input not being 'post'-ed if unchecked. What is the best way to uncheck this? Should I add a default value of 0? Or unset/delete the attribute before save in the controller? Should I add get/set methods to the model?

  • How to cancel a deeply nested process

    - by Mystere Man
    I have a class that is a "manager" sort of class. One of it's functions is to signal that the long running process of the class should shut down. It does this by setting a boolean called "IsStopping" in class. public class Foo { bool isStoping void DoWork() { while (!isStopping) { // do work... } } } Now, DoWork() was a gigantic function, and I decided to refactor it out and as part of the process broke some of it into other classes. The problem is, Some of these classes also have long running functions that need to check if isStopping is true. public class Foo { bool isStoping void DoWork() { while (!isStopping) { MoreWork mw = new MoreWork() mw.DoMoreWork() // possibly long running // do work... } } } What are my options here? I have considered passing isStopping by reference, which I don't really like because it requires there to be an outside object. I would prefer to make the additional classes as stand alone and dependancy free as possible. I have also considered making isStopping a property, and then then having it call an event that the inner classes could be subscribed to, but this seems overly complex. Another option was to create a "Process Cancelation Token" class, similar to what .net 4 Tasks use, then that token be passed to those classes. How have you handled this situation? EDIT: Also consider that MoreWork might have a EvenMoreWork object that it instantiates and calls a potentially long running method on... and so on. I guess what i'm looking for is a way to be able to signal an arbitrary number of objects down a call tree to tell them to stop what they're doing and clean up and return.

  • Posting form using javascript and json with nested objects

    - by Tim
    I have an html form that has the following structure: <input type="text" name="title" /> <input type="text" name="persons[0].name" /> <input type="text" name="persons[0].color" /> <input type="text" name="persons[1].name" /> <input type="text" name="persons[1].color" /> I would like to serialize this into the following json: { "title":"titlecontent", "persons":[ { "name":"person0name", "color":"red" }, { "name":"person1name", "color":"blue" } ] } Notice that the number of persons can vary from case to case. The structure of the html form can change, but the structure of the submitted json can't. How is this done the easiest?

  • GetValue on static field inside nested classes.

    - by Sir Gallahad
    Hi... I have the following class declared. I need to retreive the class structure and the static values without instanciate it. public MyClass() { public static string field = "Value"; public nestedClass() { public static string nestedField = "NestedValue"; } } I've successfuly used GetFields and GetNestedType to recover the class structure and GetValue(null) works fine on field, but not on nestedField. Let me sample: var fi = typeof(MyClass).GetField("field", BindingFlags.Public | BindingFlags.Static); var nt = typeof(MyClass).GetNestedType("nestedClass", BindingFlags.Public); var nfi = nt.GetField("nestedField", BindingFlags.Public | BindingFlags.Static); // All the above references are detected correctly var value = fi.GetValue(null); // until here everything works fine. value == "Value" var nestedValue = nfi.GetValue(null); // this one does not work!! Anyone knows why the last line does not work and how to work around? Thanks.

  • Firefox can not layout nested tables properly?

    - by ooplidi
    I want to implement a collapsible menu. I plan to use table component to simulate a menu, and nest a sub table into a table cell to simulate a sub menu. Below is my code, it works as expected in IE, Chrome and Safari, but it doesn't work well in Firefox: <html> <body> <div id="menu" style="position:absolute; left:150px; top:100px; z-index:1"> <table width="200px" height="90" border=1 cellpadding="0" cellspacing="0"> <tr> <td colspan=2>Money</td> </tr> <tr> <td colspan=2>Tool</td> </tr> <tr> <td>Food <table style="position:absolute; left:200px; top:60px; z-index:1" width="200px" height="60px" border="1" cellpadding="0" cellspacing="0"> <tr> <td>Cookie</td> </tr> <tr> <td>Fruit <table style="position:absolute; left:200px; top:30px; z-index:1" width="200px" height="60px" border="1" cellpadding="0" cellspacing="0"> <tr> <td>Apple</td> </tr> <tr> <td>Banana</td> </tr> </table> </td> </tr> </table> </td> </tr> </table> </div> </body> </html> It seems that Firefox think the "left" and "top" attribute for the level 3 menu is relative to the level 1 menu, so it layout the level 3 menu incorrectly. Other browsers will calculate the offset base on the level 2 menu, that works as expected. Is it a bug in Firefox? If so how can I work around it? I want my code to have the same behavior in all major browsers.

  • Accessing a nested hash in a controller

    - by Magicked
    I have the following (snipped) parameters passed into my controller. Parameters: {"commit"=>"OK", "action"=>"set_incident_incident_status_id", "id"=>"1", "controller"=>"incidents", "incident"=>{"incident_status_id"=>"1"}} I know that if I want to select the incident, I can do: @incident = Incident.find(params[:id]) How do I access the "incident"={"incident_status_id"="1"}? I thought to try something like: @incident_status = IncidentStatus.find(params[:incident => :incident_status_id]) But that didn't work. I'm assuming it's just a syntax problem at this point, and I haven't found a solution yet. Any help would be much appreciated!

  • What are the javascript performance tradeoffs in adding id's to dom elements?

    - by Blinky
    For example, I have a website which has a dynamically-generated segment of its dom which looks roughly like this: <div id="master"> <div class="child"> ... </div> <div class="child"> ... </div> <div class="child"> ... </div> ... <div class="child"> ... </div> </div> There might be hundreds of child elements in this manner, and they, too, might have yet more children. At present, none of them have id's except for the master. Javascript manipulates them via dom-walking. It's a little scary. I'd like to add id's, e.g.: <div id="master"> <div id="child1" class="child"> ... </div> <div id="child2" class="child"> ... </div> <div id="child3" class="child"> ... </div> ... <div id="childN" class="child"> ... </div> </div> What are the tradeoffs in adding id's to these divs? Certainly, jQuery must maintain a hash of id's, so there's going to be some sort of performance hit. Any general guidelines in when adding additional id's is a bad idea? Is jQuery so awesome that, in practice, it doesn't matter?

  • Behavior of nested finally in Exceptions

    Hello: Today at work, I had to review a code snippet that looks similar to this mock example. package test; import java.io.IOException; import org.apache.log4j.Logger; public class ExceptionTester { public static Logger logger = Logger.getLogger(ExceptionTester.class); public void test() throws IOException { new IOException(); } public static void main(String[] args) { ExceptionTester comparator = new ExceptionTester(); try { try { comparator.test(); } finally { System.out.println("Finally 1"); } } catch(IOException ex) { logger.error("Exception happened" ex); // also close opened resources } System.out.println("Exiting out of the program"); } } It's printing the following output.I expected an compile error since the inner try did not have a catch block. Finally 1 Exiting out of the program I do not understand why IOException is caught by the outer catch block. I would appreciate if anyone can explain this, especially by citing stack unwinding process

  • jeditable accidentally triggering on Draggable on nested items

    - by ripper234
    I'm using jquery-ui's draggable for drag-and-drop, and jeditable for inline editing. When I drag and drop an element that's also editable, right after it's dropped jeditable kicks in and pops into 'edit mode'. How can I disable this behavior? Edit - the problem happens because of netsting - see this example. I also added draggable to the mix to make the example more realistic (the actual real problem is in this site that I'm working on) Note - even though this question has an accepted answer because of the bounty rules, the problem is still not resolved for me.

  • Attempt to create nested for loops generating missing arguments error

    - by JerryK
    Am attempting to teach myself to program using Tcl. (I want to become more familiar with the language to understand someone else's code - SCID chess) The task i've set myself to motivate my learing of Tcl is to solve the 8 queens problem. My approach to creating a program is to sucessively 'prototype' a solution. So. I'm up to nesting a for loop holding the q pos on row 2 inside the for loop holding the q pos on row 1 Here is my code set allowd 1 set notallowd 0 for {set r1p 1} {$r1p <= 8} {incr r1p } { puts "1st row q placed at $r1p" ;# re-initialize r2 'free for q placemnt' array after every change of r1 q pos: for {set i 1 } {$i <= 8} {incr i} { set r2($i) $allowd } for { set r2($r1p) $notallowd ; set r2([eval $r1p-1]) $notallowd ; set r2([eval $r1p+1]) $notallowd ; set r2p 1} {$r2p <= 8} { incr r2p ;# end of 'next' arg of r2 forloop } ;# commnd arg of r2 forloop placed below: {puts "2nd row q placed at $r2p" } } My problem is that when i run the code the interpreter is aborting with the fatal error: "wrong #args should be for start test next command. I've gone over my code a few times and can't see that i've missed any of the for loop arguments.

I've tried at the role level with: { "defaults": { "chef_client": { "interval":15 } }, "overrides":{ } } and at the node level with: { "chef_client": { "interval":25 }, "tags":[] } but the interval on the node is still 1800 (default)

  • Proper usage of Java Weak Reference in case of nested collections

    - by Tong Wang

I use Google collections' MapMaker, like this: Map<Class<? extends Object>, Set<Foo>> map = new MapMaker().weakKeys().weakValues().makeMap(); So, for Set<Foo>, can I use a normal HashSet? Or, do I have to create a weak HashSet, like this: Collections.newSetFromMap(new WeakHashMap<Foo, Boolean>()); And why? Another question, the key of my map is Class objects, when will a Class object become weakly reachable? In other words, what is the lifetime of a Class object? Thanks.

  • File::Find and $_ in nested subroutines.

    When running the following code, the filenames of all files below C:\Test are printed. Why doesn't it print just Hello (n times, depending on how many files are processed)? Does this imply that I cannot rely on shift to reliably assign to $_? Imagine a coworker implements the wtf function and doesn't know that it's called from a File::Find wanted sub. I run this code with Strawberry Perl 5.12 use strict; use warnings; use File::Find; find(\&wanted, "C:\\test"); sub wanted{ wtf("Hello"); } sub wtf { shift; print; #expecting Hello }
