Hello,
i need to unescape api's $.fn.dataTable.util.escapeRegex(). I need it to restore state of column filters made with select fields.
I'm doing the select fields with this:
initComplete: function () {
this.api().columns('.select-filter').every(function () {
var column = this;
var select = $('<select><option value=""></option></select>')
.appendTo($(column.footer()).empty())
.on('change', function () {
var val = $.fn.dataTable.util.escapeRegex(
$(this).val()
);
column
.search(val ? '^' + val + '$' : '', true, false)
.draw();
});
column.data().unique().sort().each(function (d, j) {
select.append('<option value="' + d + '">' + d + '</option>')
});
and restoring state with this:
var state = table.state.loaded();
if (state) {
table.columns().eq(0).each(function (colIdx) {
var colSearch = state.columns[colIdx].search;
// alert(colSearch.search.slice(1, -1))
if (colSearch.search) {
$('select', table.column(colIdx).footer()).val(colSearch.search.slice(1, -1));
}
});
table.draw();
}
Above code works for me, except situation, when colSearch.search.slice(1, -1) retruns values with special characters. They are with escapes (made by $.fn.dataTable.util.escapeRegex). So i need to do something like unescape this value. Does anyone tried to do that ?
