我在两个元素上有一个mouseenter
事件。 mouseenter
显示具有内容的div;在每个div中,都有一个按钮,我想在其中附加一个事件以监听click
或tap
,这将允许删除自身,即div。
这是jQuery中的脚本:
$(function() {
var $subnav = $('.subnav');
$("#discover #watch").on({
mouseenter: function(e) {
$subnav.show();
$(".close").on('click tap', function(e) {
if ($subnav) $subnav.hide();
else $subnav.show();
});
},
mouseleave: function() {
$subnav.hide();
}
});
$(function() {
var $subnav = $('.subnav');
$("#discover #watch").on({
mouseenter: function(e) {
$subnav.show();
$(".close").on('click tap', function(e) {
if ($subnav) $subnav.hide();
else $subnav.show();
});
},
mouseleave: function() {
$subnav.hide();
}
});
});

我在做什么错了?
更新
显然我不得不更新脚本,因为我没有意识到它们是与JS冲突的CSS代码。作为解决方法,我必须使用jQuery选择器实际选择:hover
状态。该脚本有效,但只能运行一次。
$(document).ready(function() {
var $subnav = $('.subnav');
$(".close").on('click tap', function(e) {
if (!$subnav) {
$subnav.show();
}
$subnav.hide();
});
$('.discover:hover, .watch:hover').on({
mouseenter: function() {
if (!$subnav) {
$subnav.show();
}
$subnav.hide();
},
mouseleave: function() {
if ($subnav) {
$subnav.hide();
}
$subnav.show();
}
}
答案 0 :(得分:1)
请在两个ID选择器之间添加一个逗号=>#discover,#watch。为了安全起见,将代码包装在文档中,然后将close事件处理程序放到鼠标进入/离开的外部,因此仅应用一次。参见下面的代码:
$(document).ready(function () {
var $subnav = $('.subnav');
$(".close").on('click tap', function (e) {
if ($subnav) $subnav.hide();
else $subnav.show();
});
$("#discover, #watch").on({
mouseenter: function (e) {
$subnav.show();
},
mouseleave: function () {
$subnav.hide();
}
});
});
答案 1 :(得分:1)
如果要使用纯JavaScript,则需要:
通过在subnav
div中添加display:none;
css属性,确保默认情况下两个subnav
div都被隐藏。
然后,您可以使用getComputedStyle()来检索该display
属性值,并基于该检索到的值,只要{{{ 1}}或subnav
事件被触发。
最后,只要单击子mouseenter
元素,就可以使用parentElement()属性关闭父mouseleave
div。
您可以在上述jsFiddle或下面的代码段中查看我上面所描述内容的实际示例:
subnav
X
var discover = document.getElementById("discover");
var watch = document.getElementById("watch");
var close = document.querySelectorAll(".close");
function openSub(e) {
var subNav = e.target.childNodes[5];
var x = window.getComputedStyle(subNav);
if (x.display == "none") {
subNav.style.display = "block";
} else {
subNav.style.display = "none";
}
}
function closeSub(e) {
var subNav = e.target.childNodes[5];
subNav.style.display = "none";
}
discover.addEventListener("mouseenter", openSub);
watch.addEventListener("mouseenter", openSub);
discover.addEventListener("mouseleave", closeSub);
watch.addEventListener("mouseleave", closeSub);
function btnSub(e) {
e.target.parentElement.style.display = "none";
}
close.forEach(btn => {
btn.addEventListener("click", btnSub);
});
答案 2 :(得分:0)
您需要在被单击元素的上下文中找到按钮:
$(e.target).find(".close").on ....
答案 3 :(得分:0)
从现有.close
侦听器中移除mouseenter
单击事件侦听器,并定位父元素。
$(".close").on('click tap', function(e) {
$(this).parent().hide();
});
更新的解决方案
我还删除了条件语句,好像.close
元素仅在父级可见的情况下才可以单击,因此无需注意“隐藏的父级”
