我有一个类别下拉列表和具有类名称的多个div,我希望当用户选择时,从下拉列表中选择并根据所选选项过滤div,例如,当用户选择该类别时,我有一个名为makeup的类别我只想显示带有类组成的div,这是我尝试过的:
$('#categories').change(function() {
var val = $(this).val();
if (val == "makeup") {
$('.makeup').fadeIn();
} else {
$(".makeup").not('.' + value).fadeOut();
$('.makeup').filter('.' + value).fadeIn();
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="categories">
<option selected disabled>Choose category</option>
<option value="makeup">Make-up</option>
<option value="cafes">Cafes</option>
<option value="other">Other</option>
</select>
<div class="makeup">
Div 1
</div>
<div class="makeup">
Div 2
</div>
<div class="makeup">
Div 3
</div>
<div class="other">
Div 4
</div>

此代码按要求工作,我刚刚将类.category-option
添加到了要淡入淡出的元素中。
$('#categories').change(function() {
// Get value of selected option
var val = $(this).children("option:selected").val();
// Fadeout all that are not linked
$(".category-option").fadeOut();
// Fade in appropriate options
$(".category-option." + val).fadeIn();
});
