您可以使用jQuery轻松完成此操作。如果你给第一个选择id为“type”,你可以添加以下jQuery:
$(document).ready(function(){
$("select[name='txt_specialize']").hide();
$("select#type").change(function(){
if($(this).val() == 'Doctor')
{
$("select[name='txt_specialize']").hide();
}
else
$("select[name='txt_specialize']").show();
});
});

将数据属性添加到txt_specialize $ s并完成写脚本,如下所示: 选择医生
$('#doctor').change(function(e){
var doc = $('#doctor').val();
$("#specialist option").each(
function(){
if ($(this).attr('data-doctor')==doc){
$(this).show()
}else{
$(this).hide()
}
})
})
