复选框子类别隐藏,直到父复选框被选中
Checkbox subcategories hidden until parent checkbox selected
我正在尝试让子类别复选框仅在相关父复选框被选中后显示。
目前我正在使用以下代码:
<script type="text/javascript">
$(document).ready(function () {
$("#listing_category-401 .children").css("display", "none");
$(".option").change(function () {
if ($('checkbox[id="in-listing_category-401"] :checked').val() == "true") {
$("#listing_category-401 .children").slideDown("fast");
}
});
});
好的,方法略有不同,但下面的方法会起作用,这里是 fiddle:https://jsfiddle.net/pxt4x7q1/
这是代码:
HTML
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>
<li id="listing_category-401"><label class="selectit"><input value="401" type="checkbox" class="required option" name="_listing_category[]" id="in-listing_category-401" aria-required="true"> Artists/Bands</label>
<ul class="children">
<li id="listing_category-399"><label class="selectit"><input value="399" type="checkbox" class="required" name="_listing_category[]" id="in-listing_category-399" aria-required="true"> Acoustic Artists/Bands</label></li>
<li id="listing_category-402"><label class="selectit"><input value="402" type="checkbox" class="required" name="_listing_category[]" id="in-listing_category-402" aria-required="true"> Alternative Artists/Bands</label></li>
</ul>
</li>
风格:
<style TYPE="text/css" MEDIA=screen>
.children {
display:none
}
</style>
JAVASCRIPT:
$(document).ready(function () {
$('#in-listing_category-401').change(function () {
if (this.checked) {
$("#listing_category-401 .children").slideDown("fast");
}
else {
$("#listing_category-401 .children").slideUp("fast");
}
})
})
