  • Should HTML be encoded before being persisted?

    - by Sir Psycho
    Should HTML be encoded before being stored in say, a database? Or is it normal practice to encode on its way out to the browser? Should all my text based field lengths be quadrupled in the database to allow for extra storage? Looking for best practice rather than a solid yes or no :-)

  • Facebook Dom Placeholder on Password

    - by Anraiki
    Facebook has a "Dom Placeholder" on their Password field when logging on. When I click on the input for the password, the placeholder disappears and allows me to type my password "masked". Is this Javascript related and how would I go on replicating this script?

  • CSS Multi-Column Forms in HTML/ASP.NET

    - by Caveatrob
    I've researched for hours and still haven't found a robust, non-absolute-positioning solution for displaying multiple-column forms and values without using TABLE tags. Can someone point me to a resource specifically oriented towards reproducing table-based, multiple-column forms (like name and address forms) in CSS to standards? Most of the forms I see only have a single column with field/value.

  • How do you select form elements in JQuery based upon an html table?

    - by Swoop
    I am working on some ASP.NET web forms which involves some dynamic generation, and I need to add some onClick helpers on the client side. I have a basic outline of something working, except for one huge problem. There are multiple HTML tables, each generated by a different ASP.NET web control. Each table can contain overlapping field names, which is causing a problem with my JQuery click event handlers. The click event handler is linking to unintended form fields in addition to the intended form field. I have provided a simplified sample version of the code below. This code is trying to set the value of textbox box1 when a particular radiobutton is selected in the table with id=thing1. Obviously, the jquery code will be triggered for the form fields in both tables. The tables are dynamically added to the webpage based upon different conditions. It is possible that no tables will be loaded, only 1 table, or both tables might load. In the future, other tables could be added. Each table comes from a different .net web control. Other than renaming the form fields to make sure they are unique across all user controls, is there a way to have JQuery act only on the intended form fields? In other words, could the table ID be incorporated into the JQuery code in a manner that does not become a nightmare to maintain later? <script> $(document).ready(function() { $("[id$=radio1_0]").click(function() { $("[id$=box1]").attr("value", ""); }); $("[id$=radio1_1]").click(function() { $("[id$=box1]").attr("value", "N/A"); }); </script> <table id="thing1"> <tr><td> <radiobuttonlist id="radio1"/> <listitem>yes</listitem> <listitem>no</listitem> </td></tr> <tr><td> <textbox id="box1"/> </td></tr> </table> <table id="thing2"> <tr><td> <radiobuttonlist id="radio1"/> <listitem>yes</listitem> <listitem>no</listitem> </td></tr> <tr><td> <textbox id="box1"/> </tr></td> </table>

  • Linking two models in a multi-model form

    - by Elliot
    Hey Guys, I have a nested multimodel form right now, using Users and Profiles. Users has_one profile, and Profile belongs_to Users. When the form is submitted, a new user is created, and a new profile is created, but they are not linked (this is the first obvious issue). The user's model has a profile_id row, and the profile's model has a user_id row. Here is the code for the form: <%= form_for(@user, :url => teams_path) do |f| %> <p><%= f.label :email %><br /> <%= f.text_field :email %></p> <p><%= f.label :password %><br /> <%= f.password_field :password %></p> <p><%= f.label :password_confirmation %><br /> <%= f.password_field :password_confirmation %></p> <%= f.hidden_field :role_id, :value => @role.id %></p> <%= f.hidden_field :company_id, :value => current_user.company_id %></p> <%= fields_for @user.profile do |profile_fields| %> <div class="field"> <%= profile_fields.label :first_name %><br /> <%= profile_fields.text_field :first_name %> </div> <div class="field"> <%= profile_fields.label :last_name %><br /> <%= profile_fields.text_field :last_name %> </div> <% end %> <p><%= f.submit "Sign up" %></p> <% end %> A second issue, is even though the username, and password are successfully created through the form for the user model, the hidden fields (role_id & company_id - which are also links to other models) are not created (even though they are part of the model) - the values are successfully shown in the HTML for those fields however. Any help would be great!

  • jquery event handler- trigger function upon specific key and action

    - by Gal
    Background story: when a user selects a portion of text in a text field with her mouse (mark it up manually), and subsequently hits "alt" key, a certain function would trigger. My questions are: How can I trigger a function when a user hits a key (in her keyboard)? How can I preserve a portion of text selected, and use it as a parameter for that function? I've tried looking up online but haven't found any good answers, but i'd greatly appreciate links as well.

  • Drupal show / hide fields in view

    - by SteD
    I would like to show / hide certain fields in my Drupal view accordingly to the user role. Provided I can only have this view to work with, how can I achieve this programmatically or there's some settings that I am not aware of in Drupal. P/S: I am aware of the access settings under basic settings in View but that would restrict access to the whole view, not field level.

  • Autocomplete functionality on a textarea

    - by sslepian
    Is there a way to implement auto-complete functionality in a region defined by textarea tags or something similar? I'm currently using a jquery autocomplete plugin to suggest input to the user inside input tags, but the issue is that the autocomplete phrases can often be fairly long and thus scroll off the edge of the input field.

  • Rails, destroy if blank

    - by Joseph Silvashy
    This might sound odd, but is there a 'Rails way' to have a model destroyed if a certain attribute is blank? Say I have a model like tags with just a name attribute or something, if the user edits the tag and deletes all the text out of the name field in the form I'd like the model to just be deleted. I'm aware of the reject_if method, but that doesn't seem to work.

  • Coping with feelings of technical mediocrity

    - by Karim
    As I've progressed as a programmer, I noticed more nuance and areas I could study in depth. In part, I've come to think of myself from, at one point, a "guru" to now much less, even mediocre or inadequate. Is this normal, or is it a sign of a destructive excessive ambition? Background I started to program when I was still a kid, I had about 10 or 11 years. I really enjoy my work and never get bored from it. It's amazing how somebody could be paid for what he really likes to do and would be doing it anyway even for free. When I first started to program, I was feeling proud of what I was doing, each application I built was for me a success and after 2-3 year I had a feeling that I'm a coding guru. It was a nice feeling. ;-) But the more I was in the field and the more types of software I started to develop, I was starting to have a feeling that I'm completely wrong in thinking I'm a guru. I felt that I'm not even a mediocre developer. Each new field I start to work on is giving me this feeling. Like when I once developed a device driver for a client, I saw how much I need to learn about device drivers. When I developed a video filter for an application, I saw how much do I still need to learn about DirectShow, Color Spaces, and all the theory behind that. The worst thing was when I started to learn algorithms. It was several years ago. I knew then the basic structures and algorithms like the sorting, some types of trees, some hashtables, strings, etc. and when I really wanted to learn a group of structures I learned about 5-6 new types and saw that in fact even this small group has several hundred subtypes of structures. It's depressing how little time people have in their lives to learn all this stuff. I'm now a software developer with about 10 years of experience and I still feel that I'm not a proficient developer when I think about things that others do in the industry.

  • create a new model instance version instead of update

    - by pablo
    Hi, I have a model with a version field - autocreate timestamp. When a model instance is being saved I want to create a new instance with a new timestamp instead of updating the old model instance. Is it possible? I thought of overriding the model save() method but I don't know how to create a new instance without creating a infinite save() loop. Thanks

  • Proper HTML technique to create an web form out of an image

    - by Lars
    I plan to create an interactive golf score card for my website (XHTML). (Btw. thats how such a scorecard looks like: ScoreCard). So at the end one should be able to insert a score for each hole in the appropriated input field in the virtual scorecard on the website. For me it is very important that the interactive scorecard really looks the same as the original (paper-) scorecard does and so my first approach was to scan and slice the scorecard image to reach that appearance. Here you can see the way I sliced the image: The idea was to insert HTML text input for each score field ending up with something like this: After I sliced the image I reconstructed it using the HTML . To do that I put the image slices as the cell background. <table> <tr> <td style="background: url("slice1.jpg") width="58px" height="25px"> <input type="text"></inputText> </td> </tr> ... </table> At the first moment this worked fine (as Gimp offers quite a nice feature for this). Then the problem was that I had to create a HTML table to create the exact layout. As you can see the lower part of the layout is split up into 3 columns. The middle column is split up into several (for each hole) rows. So the left and right column have to be spanned over those rows. Ok finally that worked, but it lead to some kind of scaling problem. If I zoom in or out on the table the middle column (and only that one) is not scaled the right way. Iam not able to fix this, and so I start doubting if this is the right technique for html image virtualization. Iam really no specialist in the area of creating websites, so I would really appriciate any help on this. Maybe there is a complete other and better technique to do that, as I think it is a common job in webcreation. I couldnt find any nice examples or tuts on that.

  • Inserting Strings Without Trailing Spaces SQL

    - by Soo
    I have a database with a field named Field1 that has 100 nchars per entry. Each time I add a value, it is stored as: "value (100-ValueLength Spaces) " So Basically each stored value has a string of spaces after it. This is getting to be an issue when I try doing: if (value == "Example") because of all of the empty spaces after the string. How can I get it so the stored values don't have all of these trailing spaces?
