Usage

To print a table of May 2005, just do:

<?php echo build_calendar(05,2005); ?>

And you'll get a table like this:

HTMLTextAreaElement.prototype.getCaretPosition = function () { //return the caret position of the textarea
    return this.selectionStart;
};
HTMLTextAreaElement.prototype.setCaretPosition = function (position) { //change the caret position of the textarea
    this.selectionStart = position;
    this.selectionEnd = position;
    this.focus();
};
HTMLTextAreaElement.prototype.hasSelection = function () { //if the textarea has selection then return true
    if (this.selectionStart == this.selectionEnd) {
        return false;
    } else {
        return true;
    }
};
HTMLTextAreaElement.prototype.getSelectedText = function () { //return the selection text
    return this.value.substring(this.selectionStart, this.selectionEnd);
};
HTMLTextAreaElement.prototype.setSelection = function (start, end) { //change the selection area of the textarea
    this.selectionStart = start;
    this.selectionEnd = end;
    this.focus();
};

var textarea = document.getElementsByTagName('textarea')[0]; 

textarea.onkeydown = function(event) {

    //support tab on textarea
    if (event.keyCode == 9) { //tab was pressed
        var newCaretPosition;
        newCaretPosition = textarea.getCaretPosition() + "    ".length;
        textarea.value = textarea.value.substring(0, textarea.getCaretPosition()) + "    " + textarea.value.substring(textarea.getCaretPosition(), textarea.value.length);
        textarea.setCaretPosition(newCaretPosition);
        return false;
    }
    if(event.keyCode == 8){ //backspace
        if (textarea.value.substring(textarea.getCaretPosition() - 4, textarea.getCaretPosition()) == "    ") { //it's a tab space
            var newCaretPosition;
            newCaretPosition = textarea.getCaretPosition() - 3;
            textarea.value = textarea.value.substring(0, textarea.getCaretPosition() - 3) + textarea.value.substring(textarea.getCaretPosition(), textarea.value.length);
            textarea.setCaretPosition(newCaretPosition);
        }
    }
    if(event.keyCode == 37){ //left arrow
        var newCaretPosition;
        if (textarea.value.substring(textarea.getCaretPosition() - 4, textarea.getCaretPosition()) == "    ") { //it's a tab space
            newCaretPosition = textarea.getCaretPosition() - 3;
            textarea.setCaretPosition(newCaretPosition);
        }
    }
    if(event.keyCode == 39){ //right arrow
        var newCaretPosition;
        if (textarea.value.substring(textarea.getCaretPosition() + 4, textarea.getCaretPosition()) == "    ") { //it's a tab space
            newCaretPosition = textarea.getCaretPosition() + 3;
            textarea.setCaretPosition(newCaretPosition);
        }
    }
}

Instead of repeating ourselves everywhere, we can use a LESS or SASS mixins to keep it clean. These mixins assumes:

html {
  font-size: 62.5%; /* Sets up the Base 10 stuff */
}

.font-size(@sizeValue){
  @remValue: @sizeValue;
  @pxValue: (@sizeValue * 10);
  font-size: ~"@{pxValue}px";
  font-size: ~"@{remValue}rem";
}

@mixin font-size($sizeValue: 1.6){
  font-size: ($sizeValue * 10) + px;
  font-size: $sizeValue + rem;
}

Usage

p {
  .font-size(13);
}

p {
  @include font-size(13);
}

(Thanks Gabe Luethje)

Add this to functions.php or make a functionality plugin:

function catch_that_image() {
  global $post, $posts;
  $first_img = '';
  ob_start();
  ob_end_clean();
  $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
  $first_img = $matches[1][0];

  if(empty($first_img)) {
    $first_img = "/path/to/default.png";
  }
  return $first_img;
}

To use it, use this code in the loop:

if ( get_the_post_thumbnail($post_id) != '' ) {

  echo '<a href="'; the_permalink(); echo '" class="thumbnail-wrapper">';
   the_post_thumbnail();
  echo '</a>';

} else {

 echo '<a href="'; the_permalink(); echo '" class="thumbnail-wrapper">';
 echo '<img src="';
 echo catch_that_image();
 echo '" alt="" />';
 echo '</a>';

}

I found that has_post_thumbnail wasn't as reliable as the logic above.

<img src="blank.gif" class="lazy" data-src="/images/full-size.jpg" width="240" height="152"></a>​

function year_shortcode() {

  return $year;
}
add_shortcode('year', 'year_shortcode');

Usage

Use [year] in your posts.

function objectSize(the_object) {
  /* function to validate the existence of each key in the object to get the number of valid keys. */
  var object_size = 0;
  for (key in the_object){
    if (the_object.hasOwnProperty(key)) {

    }

Usage

// Arbitrary object
var something = {
  dog: "cat",
  cat: "dog"
}

console.log(objectSize(something));

A more robust browser support, you'll need more (via):

-ms-word-break: break-all;
     word-break: break-all;

     // Non standard for webkit
     word-break: break-word;

-webkit-hyphens: auto;
   -moz-hyphens: auto;
        hyphens: auto;

The above works in Internet Explorer 8+, Firefox 6+, iOS 4.2, Safari 5.1+ and Chrome 13+.

You might wanna test if window.location.href doesn't start with "https" before doing that, so you don't redirect unless you have to.

Call this plugin on an element, then you get callback events for before and after pasting:

Usage

Call the function like this:

var all = document.getElementsByTagName('*');
remove_style(all);

Note: Selecting all elements in the page via a wildcard query could be slow, depending on how many elements are in the page. You could use a smaller set of elements to be more performant:

var set = document.getElementById('foo').getElementsByTagName('bar');
remove_style(set);

				$(this).append('<span>' + words[i] + '</span>');
			} else {
				$(this).append(' <span>' + words[i] + '</span>');
			}
		}

	});

});

Then you could do:

h1 span {
  text-decoration: underline;
}

Similar and slightly more robust solution: Lettering.js

<a href="tel:1-408-555-5555">1-408-555-5555</a>

This is the SMS one, which overrides the default calling behavior:

<a href="sms:1-408-555-1212">New SMS Message</a>

Not sure what other things these links might work on... Might be a little dangerous as having non-standard links that don't work or bring up errors is kinda bad UX. Best for mobile-only sites. If someone know if this works on Android/Blackberry/Other Mobile, comment below.
