我有以下代码:
<select>
<option value="Type 1">Type 1</option>
<option value="Type 2">Type 2</option>
<option value="Type 3">Type 3</option>
<option value="Other">Other</option>
</select>
<input type="text" id="other" />
我想要做的是使用jQuery默认隐藏下面的文本框,然后在用户从下拉列表中选择其他选项时显示它。

这里不需要任何CSS。
$('#sel').change(function() {
var selected = $(this).val();
if(selected == 'Other'){
$('#other').show();
}
else{
$('#other').hide();
}
});

试试这个:
<select id="selectbox_id">
<option value="Type 1">Type 1</option>
<option value="Type 2">Type 2</option>
<option value="Type 3">Type 3</option>
<option value="Other">Other</option>
</select>
<input type="text" id="other" />
<强> JQuery的:强>
$(function(){
// hide by default
$('other').css('display', 'none');
$('selectbox_id').change(function(){
if ($(this).val() === 'Other') {
$('other').css('display', 'block');
}
});
});
