I would like to make my table filter more elegant. Basically, this table will have links at the bottom to hide and show rows based on attributes in the table. It's working the way I want, but I feel like I could have written using a lot fewer lines of jQuery... Anyone have any ideas?
Here's the jsfiddle: /
And the code:

Reset to default 3$(document).ready(function()
{
$('.filtertable a[data-color]').click(function() {
var color = $(this).data().color;
if(color == 'all'){
$('td[data-color]').parent().show();
} else {
$('td[data-color='+ color +']').parent().show();
$('td[data-color!='+color+']').parent().hide();
}
});
}
);
I frequently use CSS for this sort of thing.
<table id="myTable" class="all">
<tr class="red"><td>red</td></tr>
<tr class="yellow"><td>yellow</td></tr>
<tr class="blue"><td>blue</td></tr>
<table>
<div class="controls">
<a href="#" data-color="all">All</a>
<a href="#" data-color="red">Red</a>
<a href="#" data-color="white">White</a>
<a href="#" data-color="blue">Blue</a>
</div>
And then in JS
$('.controls a').on('click', function(e){
e.preventDefault();
var c= $(this).data('color');
$('#myTable')[0].className = c;
});
The CSS determines what shows when:
tr { display: none; }
.all tr { display: table-row; }
.red tr.red { display: table-row; }
.blue tr.blue { display: table-row; }
.yellow tr.yellow { display: table-row; }
In JSFiddle.
Here's a demo
$(function() {
var td = $('#colortable td');
$('.filtertable').on('click', 'a', function() {
var color = this.getAttribute('data-color');
if (color === 'all') {
td.parent().show()
} else {
td.filter('[data-color=' + color + ']').parent().show()
td.filter('[data-color!=' + color + ']').parent().hide()
}
});
});
http://jsfiddle/vC88q/6/
$('.filtertable a[data-color]').click(function() {
var color = $(this).data().color;
$('td[data-color=' + color + ']').parent().show();
$('td[data-color!=' + color + ']').parent().hide();
});
The following should replace all your code.
$(document).ready(function() {
$('.filtertable a[data-color]').click(function() {
var $this = $(this), color = $this.data('color');
if (color !== 'all') {
$('td[data-color]').parent().hide();
}
$('td[data-color' + (color !== 'all' ? '=' + color : '') + ']').parent().show();
});
});
EDIT: Updated to fix 'All' link
