• Hyphens or underscores in CSS and HTML identifiers?

  - by Török Gábor

  As both hyphen (-) and underscore (_) are valid characters in CSS and HTML identifiers, what are the advantages and disadvantages using one or the other? I prefer writing CSS class names with hyphens (e.g. field-text) and underscores for IDs (e.g. featured_content). Is there a best practice or it's only the matter of taste?

• RowFilter including [ character in search string

  - by JeffC

  I fill a DataSet and allow the user to enter a search string. Instead of hitting the database again, I set the RowFilter to display the selected data. When the user enters a square bracket ( "[" ) I get an error "Error in Like Operator". I know there is a list of characters that need prefixed with "\" when they are used in a field name, but how do I prevent RowFilter from interpreting "[" as the beginning of a column name?

• jQuery plug-in to remap numeric keypad

  - by Álvaro G. Vicario

  Is there a jQuery plug-in to remap the "dot" key in the numeric keypad? The purpose is to make it print a decimal separator, rather than a dot, in languages that use commas or other characters. I'd like to mimic the behaviour of some desktop applications like MS Excel. (It's okay to hard-code the output character.)

• Is there an HTML attribute to tell smartphone keyboards to show special email keys?

  - by slolife

  I notice that when using my touch-screen smartphone (no physical keyboard) that when an app asks for an email address to be entered in a textbox, the on screen keyboard is modified slightly to provide specialized keys that enter blocks of text, like '.com' or push some characters to the foreground key, like '@'. Is there an HTML attribute or style that I can add to my HTML input boxes that will tell the smartphone/browser to provide these specialized keys?

• Simple JQuery Validator addMethod not working

  - by tehaaron

  Updated question on the bottom I am trying to validate a super simple form. Eventually the username will be compared to a RegExp statement and the same will go for the password. However right now I am just trying to learn the Validator addMethod format. I currently have this script: JQuery.validator.addMethod( "legalName", function(value, element) { if (element.value == "bob") { return false; } else return true; }, "Use a valid username." ); $(document).ready(function() { $("#form1").validate({ rules: { username: { legalName: true } }, }); }); Which if I am not mistaken should return false and respond with "Use a valid username." if I were to put "bob" into the form. However, it is simply submitting it. I am linking to JQuery BEFORE Validator in the header like instructed. My uber simple form looks like this: <form id="form1" method="post" action=""> <div class="form-row"><span class="label">Username *</span><input type="text" name="username" /></div> <div class="form-row"><input class="submit" type="submit" value="Submit"></div> </form> Finally how would I go about restructing the addMethod function to return true if and false at the else stage while keeping the message alert for a false return? (ignore this last part if you don't understand what I was trying to say :) ) Thanks in advance. Thank to everyone who pointed out my JQuery - jQuery typo. New Ideally, I am trying to turn this into a simple login form (username/password). It is for demonstration only so it wont have a database attached or anything, just some simple js validations. I am looking to make the username validate for <48 characters, only english letters and numbers, no special characters. I thought a whitelist would be easiest so I had something like this: ^[a-zA-Z0-9]*${1,48} but I am not sure if that is proper JS RegExp (it varies from Ruby RegExp if I am not mistaken?...Usually I use rubular.com). Password will be similar but require some upper/lowercase and numbers. I believe I need to make another $.validator.addMethod for legalPassword that will look very similar.
