jQuery Masked Input

Andrew Burgess — Wed, 25 Aug 2010 20:42:52 +0000

Found this plugin for jQuery for masking input boxes to restrict input to a specific format.

http://digitalbush.com/projects/masked-input-plugin/

Definitely pleased with this plugin. Very easy to use, and the format for specifying masks is easy as well.

1	$("#CellPhone").mask("(999) 999-9999");

That’s how easy it is to set up a mask.

I do have one problem with it though. It’s basically a one to one mapping for characters (you can specify optional sections on the end) but it doesn’t allow something more regex based. For instance: at least one but up to three letters, followed by 6 numbers (a135923 and ab473922). I will probably try to extend it if I ever run across this situation though.

Give it a look if you need to restrict input on textboxes.

MP3 Folder Cleaner

This is just a quick Python script that I put together to help sort through my music collection. I have a pretty large one, around 24,000 tracks, and I’m trying to consolidate all of them into a more standardized bitrate of 192kbps. Since they’re all over the map, I figured I would put them into correct bitrate, over, and under folders, so that the ones that are correct can be tagged with MusicBrainz Picard, and the rest can be down converted or reacquired in order to get that consistency.

Requirements:

Python 2.5.2 or greater (older versions may work, but you should have at least this)
Mutagen (http://code.google.com/p/mutagen/) – you can install it using easy_install

Usage:

Just run the script in a command prompt, and it will ask you which directories to use.

Updates

August 19, 2010 – 11:17 PM
- Moves files based on their metadata instead of just file name
- Fixed some character handling (removing invalid filepath characters
- Handles situations where a track may not have tags

Creating a Vertically Oriented Table

Andrew Burgess — Tue, 03 Aug 2010 16:24:25 +0000

For the project that I’m working on at my company, one of the pages required developing a table that was vertically oriented (first cell in each row is a header, each data item takes a column). It also had to be editable in place, which means that using a traditional table would be extremely difficult and hackish.

I settled on using unordered lists and some jQuery to give the appearance of a table, and it seems to have worked out splendidly.

.table-container {
border: 1px solid #AAAAAA;
}
.vertical-list-container {
overflow-x:scroll;
width: 600px;
border-left: 1px solid #AAAAAA;
}
.vertical-list {
float: left;
width: 230px;
padding-bottom:10px;
}
.vertical-list .label {
padding-right: 14px;
text-align:left !important;
font-weight: bold;
}
.vertical-list li {
vertical-align: middle;
text-align: center;
margin-top: 5px;
padding: 5px 10px;
min-height: 15px;
border-bottom: 1px dotted #E0E0E0;
border-right: 1px dotted #E0E0E0;
}

jQuery magic to make it more table-y. This code basically extends the inner section (id = “scroller”) to the maximum width of the table columns (based on how many there are). It then stretches the container to fit within the whole parent container that the scroll bar will go all the way across. Finally, it loops through each column, and then uses a custom selector to find any cell heights that are above the minimum amount, and then updates all of the heights for those rows

Edit: I made a change to how the heights are calculated. I realized that a taller height in a later row wouldn’t have it’s original height recognized. I replaced it with a dictionary based approach, where each row index stores the maximum height it encounters before applying the final row heights

$.extend($.expr[':'], {
height: function (a, i, m) {
//Check to make sure it's :height(>##) or :height(<##)
if (!m[3] || !(/^(<|>)\d+$/).test(m[3])) { return false; }
return m[3].substr(0, 1) === ">" ?
$(a).height() > m[3].substr(1) : $(a).height() < m[3].substr(1);
}
});

$().ready(function () {
var scrollWidth = 230 * ($(".vertical-list-container").find(".vertical-list").length);
$("#scroller").width(scrollWidth);

var tableContainerWidth = $(".table-container").width();
$(".vertical-list-container").width(tableContainerWidth - 232);

var heights = {};
$(".vertical-list").each(function (x) {
$(this).find("li:height(>15)").each(function (index) {
var z = $(this).index();
var height = $(this).height();
if (heights[z] === undefined) {
heights[z] = height;
} else {
if (heights[z] < height) {
heights[z] = height;
}
}
});
});

$(".vertical-list").each(function (y) {
for (var key in heights) {
if (heights.hasOwnProperty(key)) {
$(this).find("li:eq(" + key + ")").height(heights[key]);
}
}
});
});

Then finally, here’s the structure for the HTML code that displays the data
