Hello,

I am using "DataTables individual column filtering example (using select menus)" http://datatables.net/examples/api/multi_filter_select.html for creating this functionality for my table.

One of the columns has rows with A HREF elements:

<a href="http://localhost/France">France</a><br />


Problem are the generated SELECT filters.
The elements in the list are generated like:
France">France
and not
France

Thanks a lot for your support!

This happens in the header, where select boxes are generated by JS (like in the example).

JS:
<script type="text/javascript" src="http://localhost/jquery.dataTables.min.js"></script>
<script type="text/javascript" src="http://localhost/TableTools.min.js"></script>

<script type="text/javascript" charset="utf-8">
			(function($) {
			/*
			 * Function: fnGetColumnData
			 * Purpose:  Return an array of table values from a particular column.
			 * Returns:  array string: 1d data array 
			 * Inputs:   object:oSettings - dataTable settings object. This is always the last argument past to the function
			 *           int:iColumn - the id of the column to extract the data from
			 *           bool:bUnique - optional - if set to false duplicated values are not filtered out
			 *           bool:bFiltered - optional - if set to false all the table data is used (not only the filtered)
			 *           bool:bIgnoreEmpty - optional - if set to false empty values are not filtered from the result array
			 * Author:   Benedikt Forchhammer <b.forchhammer /AT\ mind2.de>
			 */
			$.fn.dataTableExt.oApi.fnGetColumnData = function ( oSettings, iColumn, bUnique, bFiltered, bIgnoreEmpty ) {
				// check that we have a column id
				if ( typeof iColumn == "undefined" ) return new Array();
				
				// by default we only wany unique data
				if ( typeof bUnique == "undefined" ) bUnique = true;

					var aData = this.fnGetData(iRow);

				{
					r += '<option value="' + aData[i] + '">' + aData[i] + '</option>';
				}
				return r+'</select>';
			}
	
			jQuery.fn.dataTableExt.aTypes.push(
				function ( sData ) {
					return 'html';
				}
			);				

			function fnShowHide( iCol )
			{
				/* Get the DataTables object again - this is not a recreation, just a get of the object */
				var oTable = $('#example').dataTable();
				
				var bVis = oTable.fnSettings().aoColumns[iCol].bVisible;
				oTable.fnSetColumnVis( iCol, bVis ? false : true );
			}

			$(document).ready(function() {
				/* Initialise the DataTable */
				var oTable = $('#example').dataTable( {
					"bPaginate": false,
					"bSort": true,
					"bSortClasses": true,
					"oLanguage": {
						"sSearch": "Search all columns:",
						"sLengthMenu": ''
					}

				} );
				
				/* Add a select menu for each TH element in the table footer */
				$("thead th").each( function ( i ) {
					this.innerHTML = fnCreateSelect( oTable.fnGetColumnData(i) );
					$('select', this).change( function () {
						oTable.fnFilter( $(this).val(), i );
					} );
				} );
			} );

It is not in the header, it is in the rows.
Information in the rows need to link somewhere.

Problem is with the table headers, where select boxes are generated based on values from the rows.
These select boxes act like filters on table data. They are populated with unique records from the rows.
Problem is when they are generated, they also containt part of the a href HTML (as you can see in the example).

Thanks alot!

i suggest rather than using anchor tag in the cells of body rows', use an onclick event on the table cell

<td onclick="gotTo('france')" onmouseover = "this.style.cursor = 'pointer'" onmouseout="this.style.cursor='auto'">CellText</td>


function goTo(site)
{
   location.href = site;
}
