File size
Sort abbreviated file sizes correctly (8MB, 4KB, etc)
- Author: Allan Jardine - datatables.net
When dealing with computer file sizes, it is common to append a post fix such as B, KB, MB or GB to a string in order to easily denote the order of magnitude of the file size. This plug-in allows sorting to take these indicates of size into account.
A counterpart type detection plug-in is also available.
Plug-in code
jQuery.fn.dataTable.ext.type.order['file-size-pre'] = function ( data ) {
var matches = data.match( /^(\d+(?:\.\d+)?)\s*([a-z]+)/i );
var multipliers = {
b: 1,
bytes: 1,
kb: 1000,
kib: 1024,
mb: 1000000,
mib: 1048576,
gb: 1000000000,
gib: 1073741824,
tb: 1000000000000,
tib: 1099511627776,
pb: 1000000000000000,
pib: 1125899906842624
};
if (matches) {
var multiplier = multipliers[matches[2].toLowerCase()];
return parseFloat( matches[1] ) * multiplier;
} else {
return -1;
};
};
CDN
This plug-in is available on the DataTables CDN:
Note that if you are using multiple plug-ins, it is beneficial in terms of performance to combine the plug-ins into a single file and host it on your own server, rather than making multiple requests to the DataTables CDN.
