需要帮助或指出正确的方向选择下拉菜单中的特定字词。
例如,如果选择了选项1 - “Team1”vs“Team4”,则从第二个下拉列表中删除“Team2”和“Team3”。
<select id="gameDrop">
<option value="1">Team1 vs Team4</option>
<option value="2">Team2 vs Team3</option>
<option value="3">Team3 vs Team2</option>
<option value="4">Team4 vs Team1</option>
</select>
<select id="teamDrop">
<option value="1">Team1</option>
<option value="2">Team2</option>
<option value="3">Team3</option>
<option value="4">Team4</option>
</select>
有没有办法可以扩展以下代码,在下拉列表中选择特定的单词而不是选项值?
$('select').change(function() {
$('select').not(this).children('option[value=' + $(this).val() + ']').remove();
});

<select id="gameDrop">

<option value="2:3">Team2 vs Team3</option>
<option value="3:2">Team3 vs Team2</option>
<option value="4:1">Team4 vs Team1</option>

<select id="teamDrop">

$('#gameDrop').change(function() {
var $val = $(this).val();
$val = $val.split(':');
$('#teamDrop option').prop('disabled',true);
$.each($val,function(index,value){
$('#teamDrop option[value="'+value+'"]').prop('disabled',false);
});
})
CSS [这很重要,因为这可以隐藏不需要的选项]
select option[disabled] {
display: none;
}
