过滤正在工作,但我需要使用这两个选择下拉菜单来暗示全选。我需要的是两个选择下拉菜单都有一个全选。
HTML:
<select name="select1" id="select1">
<option Value="">All</option>
<option Value="2013-10-10">2013-10-10</option>
<option Value="2013-10-09">2013-10-09</option>
<option Value="Onion">Onion</option>
<option Value="Wewe">Wewe</option>
</select>
<select name="select2" id="select2">
<option Value="2013-10-10">2013-10-10 Style 1</option>
<option Value="2013-10-10">2013-10-10 Style 2</option>
<option Value="2013-10-10">2013-10-10 Style 3</option>
<option Value="2013-10-09">2013-10-09 Style 1</option>
<option Value="2013-10-09">2013-10-09 Style 2</option>
<option Value="2013-10-09">2013-10-09 Style 3</option>
<option Value="Orange">Orange Style 4</option>
<option Value="Onion">Onion Style 1</option>
<option Value="Onion">Onion Style 2</option>
<option Value="Wewe">wewe Style 2</option>
</select>
JavaScript:
$("#select1").change(function() {
if($(this).data('options') == undefined){
/*Taking an array of all options-2 and kind of embedding it on the select1*/
$(this).data('options',$('#select2 option').clone());
}
var id = $(this).val();
var options = $(this).data('options').filter('[value=' + id + ']');
$('#select2').html(options);
});
