The two sorting functions are typical Javascript sort methods: - * <ul> - * <li> - * Function input parameters: - * <ul> - * <li>{*} Data to compare to the second parameter</li> - * <li>{*} Data to compare to the first parameter</li> - * </ul> - * </li> - * <li> - * Function return: - * <ul> - * <li>{int} Sorting match: <0 if first parameter should be sorted lower than - * the second parameter, ===0 if the two parameters are equal and >0 if - * the first parameter should be sorted height than the second parameter.</li> - * </ul> - * </il> - * </ul> - * @type object - * @default {} - * - * @example - * // Case-sensitive string sorting, with no pre-formatting method - * $.extend( $.fn.dataTableExt.oSort, { - * "string-case-asc": function(x,y) { - * return ((x < y) ? -1 : ((x > y) ? 1 : 0)); - * }, - * "string-case-desc": function(x,y) { - * return ((x < y) ? 1 : ((x > y) ? -1 : 0)); - * } - * } ); - * - * @example - * // Case-insensitive string sorting, with pre-formatting - * $.extend( $.fn.dataTableExt.oSort, { - * "string-pre": function(x) { - * return x.toLowerCase(); - * }, - * "string-asc": function(x,y) { - * return ((x < y) ? -1 : ((x > y) ? 1 : 0)); - * }, - * "string-desc": function(x,y) { - * return ((x < y) ? 1 : ((x > y) ? -1 : 0)); - * } - * } ); - */ - "oSort": {}, + _api_register( 'destroy()', function ( remove ) { + remove = remove || false; + return this.iterator( 'table', function ( settings ) { + var orig = settings.nTableWrapper.parentNode; + var classes = settings.oClasses; + var table = settings.nTable; + var tbody = settings.nTBody; + var thead = settings.nTHead; + var tfoot = settings.nTFoot; + var jqTable = $(table); + var jqTbody = $(tbody); + var jqWrapper = $(settings.nTableWrapper); + var rows = $.map( settings.aoData, function (r) { return r.nTr; } ); + var i, ien; - /** - * Version string for plug-ins to check compatibility.
