我是一个全新的javascript新手。我正在尝试创建一个搜索栏,当用户点击我添加到顶部栏的搜索图标时会显示该搜索栏。我使用了tutorial
我根据自己的需要调整了HTML标记,但是,当我添加下面的代码时(与教程中相同),似乎出现了问题。
// Close the dropdown menu if the user clicks outside of it
window.onclick = function(event) {
if (!event.target.matches('.dropbtn')) {
var dropdowns = document.getElementsByClassName("dropdown-content");
var i;
for (i = 0; i < dropdowns.length; i++) {
var openDropdown = dropdowns[i];
if (openDropdown.classList.contains('show')) {
openDropdown.classList.remove('show');
}
}
当用户点击图标时会出现搜索栏,但如果我尝试选择搜索字段来编写某些内容,则会消失。我检查过,我注意到上面的教程有相同的行为(如果你点击下拉菜单中的一个链接,下拉菜单就会消失)。
我知道它与事件目标有关。有谁知道我应该改变什么,在哪里? HTML标记是相同的,但我添加了一个搜索表单,而不是下拉菜单。
谢谢!

这段代码会删除每个没有dropbtn
课程的div中的show class。
你可以做那样的事情
if (!event.target.matches('.dropbtn') && !event.target.matches('.searchBox')) {
var dropdowns = document.getElementsByClassName("dropdown-content");
var i;
for (i = 0; i < dropdowns.length; i++) {
var openDropdown = dropdowns[i];
if (openDropdown.classList.contains('show')) {
openDropdown.classList.remove('show');
}
}
并将.searchBox
类添加到搜索框元素中,或将其更改为已有的类。

event.target.matches
无效。使用此fiddle。愿它帮忙!
JS:
/* When the user clicks on the button,
toggle between hiding and showing the dropdown content */
function myFunction() {
document.getElementById("myDropdown").classList.toggle("show");
}
// Close the dropdown menu if the user clicks outside of it
window.onclick = function(event) {
if (event.target.className.indexOf('dropbtn') == -1) {
var dropdowns = document.getElementsByClassName("dropdown-content");
var i;
for (i = 0; i < dropdowns.length; i++) {
var openDropdown = dropdowns[i];
if (openDropdown.classList.contains('show')) {
openDropdown.classList.remove('show');
}
}
}
}

以上都没有为我工作,所以我最终自己组建了一个解决方案。我用下面的jQuery替换了javascript。
当用户点击搜索图标时,这是在slideUp和slideDown之间切换:
$( "#mobile-search-ico" ).click(function() {
$( ".mobile-search-inner" ).slideToggle(400);
});
这是在用户点击搜索框外部时切换slideUp:
$(document).mouseup(function (e)
{
var container = $(".mobile-search-inner");
if (!container.is(e.target) // if the target of the click isn't the container...
&& container.has(e.target).length === 0) // ... nor a descendant of the container
{
container.slideUp(400);
}
});
$("#mobile-search-ico").click(function() {
$(".mobile-search-inner").slideToggle(400);
});
$(document).mouseup(function(e) {
var container = $(".mobile-search-inner");
if (!container.is(e.target) // if the target of the click isn't the container...
&& container.has(e.target).length === 0) // ... nor a descendant of the container
{
container.slideUp(400);
}
});

注意:切换搜索框的搜索图标是使用linea图标字体创建的,搜索按钮是使用FontAwesome创建的。我不知道如何在这里添加,所以我把它们排除了。 “ICON”取代了搜索图标(不是按钮)。另外,造型有点不同。
