Question

如果我点击搜索栏元素以外的任何位置(输入和提交按钮(，我想要关闭搜索栏。到目前为止，我所做的是使用toggle来打开和关闭它，这是有效的。但是到目前为止，如果我点击div之外的任何地方，我都找不到关闭它的方法。代码笔：https://codepen.io/hateusall/pen/abdedJE

Answer 1

DEMO

const $toggler = $(".search-toggler");
const $wrapper = $(".search-wrapper");
$toggler.on("click", function() {
$wrapper.toggleClass("search-wrapper-active");
});
$(document).on('click', function (e) {
if ($(".search-toggler, .search-wrapper").has(e.target).length === 0) {
$wrapper.removeClass("search-wrapper-active");
}
});

你可以这样做：

[...document.querySelectorAll('body')].forEach(el => {
//get all elements in body
el.addEventListener('click', event => {
//add addEventListener
if (event.target.className.includes("search") === false) {
//if clicked element does not have class search
searchWrapper.classList.remove("search-wrapper-active");
//remove search-wrapper-active class to close it
}
})
})

这样，您就不需要任何其他东西，只需将其组合在一起即可关闭和打开(也有好处，只使用JS(：

const searchWrapper = document.querySelector(".search-wrapper");
[...document.querySelectorAll('body')].forEach(el => {
el.addEventListener('click', event => {
if (event.target.className.includes("search") === false) {
searchWrapper.classList.remove("search-wrapper-active");
} else {
searchWrapper.classList.toggle("search-wrapper-active");
}
})
})

请记住：

现在，页面上的所有元素都有了事件监听器，如果您需要它来做其他事情，只需扩展它以满足您的需求，无需在任何位置再次单击添加事件监听器。

const searchWrapper = document.querySelector(".search-wrapper");
[...document.querySelectorAll('body')].forEach(el => {
el.addEventListener('click', event => {
if (event.target.className.includes("search") === false) {
searchWrapper.classList.remove("search-wrapper-active");
} else {
searchWrapper.classList.toggle("search-wrapper-active");
}
})
})
