jQuery sortable column

163

I came across this, and thought I'd throw in my 2 cents. Click on the column headers to sort ascending, and again to sort descending.

• Works in Chrome, Firefox, Opera AND IE(8)
• Only uses JQuery
• Does alpha and numeric sorting - ascending and descending

$('th').click(function(){
    var table = $(this).parents('table').eq(0)
    var rows = table.find('tr:gt(0)').toArray().sort(comparer($(this).index()))
    this.asc = !this.asc
    if (!this.asc){rows = rows.reverse()}
    for (var i = 0; i < rows.length; i++){table.append(rows[i])}
})
function comparer(index) {
    return function(a, b) {
        var valA = getCellValue(a, index), valB = getCellValue(b, index)
        return $.isNumeric(valA) && $.isNumeric(valB) ? valA - valB : valA.toString().localeCompare(valB)
    }
}
function getCellValue(row, index){ return $(row).children('td').eq(index).text() }

table, th, td {
    border: 1px solid black;
}
th {
    cursor: pointer;
}
