Talking about technology (mostly)

Found some cool glow effects. Couldn’t actually get them to work in my context, but it’s the thought that counts.

To get the element/tag name with jQuery:

 $( '.selector' ).get( 0 ).tagName

Found this which said:

$('<div/>').text('This is fun & stuff').html();

I’m always forgetting the syntax for the jQuery ‘document ready’ event. Which is an embarrassment because it’s so simple:

$( document ).ready( handler )
$().ready( handler ) (this is not recommended)
$( handler )

I used to use the $( document ).ready( handler ) syntax, but starting today I use the $( handler ) syntax.

Using the jQuery Validation Plugin to validate my web forms… handy!

Found this article today which had a method for preserving white space in jQuery’s .val() function.

$.valHooks.textarea = {
  get: function( elem ) {
      return elem.value.replace( /\r?\n/g, "\r\n" );
}};

Today I heard from John Resig on StackOverflow about how to clone objects using jQuery:


// Shallow copy
var newObject = jQuery.extend({}, oldObject);

// Deep copy
var newObject = jQuery.extend(true, {}, oldObject);

Today I learned about the jQuery Templating Plugin. Looks like something I’ll want to learn about!

I used the jQuery.browser interface for the first time today to put in an IE hack.
