当我单击下拉菜单时,没有prpblem的打开,但是如果我单击其他下拉菜单,则两个下拉菜单都打开了,我想在单击应打开的下拉菜单时隐藏其他打开的下拉菜单。
<div class="more-options" id="PostMenu<?php echo $p_id; ?>" onclick="openMenu(<?php echo $p_id; ?>)">
<img src="../images/ellipsis-h-solid.svg" alt="">
<div class="user-setting-drop" id="openDropMenu<?php echo $p_id; ?>">
<a href="#" title="">Report</a>
</div>
</div>
<script type="text/javascript">
function openMenu(y){
//alert(001);
$('#PostMenu'+y).on('click', function () {
$('#openDropMenu'+y).toggleClass('active').siblings().removeClass('active');
return false;
});
}
</script>

$(this)
或e.target
onclick
如果您有多个标签需要注册/委托给某个事件,请使用.class
或<tagName>
-使用#id
既繁琐又不必要。
$('.more-options').on('click', function() {...
如果需要,使用$(this)
引用单击的标记,并使用链.find()
引用其后代。如果一行太笨拙,请将其存储在变量中。
var clicked = $(this).find('.user-setting-drop');
如果要“手风琴行为” ,请关闭/停用/折叠所有标签(使用.not()
除外单击的标签),然后打开/激活/展开单击的标签。< / p>
$('.user-setting-drop').not(clicked).removeClass('active');
clicked.toggleClass('active');
使用.remove
/ toggleClass()
方法。如果您想要一些动画,它涉及到CSS的更多工作。
$('.more-options').on('click', function() {
var clicked = $(this).find('.user-setting-drop');
$('.user-setting-drop').not(clicked).removeClass('active');
clicked.toggleClass('active');
});
.more-options {
cursor: pointer
}
.user-setting-drop {
max-height: 0;
color: transparent;
opacity: 0;
transition: all 0.5s;
}
.active {
height: auto;
max-height: 5000px;
color: #000;
opacity: 1;
transition: all 0.5s, max-height: 0.7s;
}

使用.slideToggle
/ Up()
方法。使用内置的动画可以减少工作量。
$('.more-options').on('click', function() {
var clicked = $(this).find('.user-setting-drop');
$('.user-setting-drop').not(clicked).slideUp(300);
clicked.slideToggle(500);
});
.more-options {
cursor: pointer;
}
.user-setting-drop {
display: none
}
