我想在点击时放置一个 cookie，以便在页面刷新后保持我的选择处于活动状态

Question

我想在页面刷新后点击一个cookie以保持我的选择处于活动状态，我在下面有以下代码：

我尝试了不同的方法，但我无法实现。我是javascript或jquery的菜鸟。

看看我到目前为止尝试过什么。我有一个函数，我想在其中设置 cookie，然后在点击事件时调用该函数。

$(function() {
//LANGUAGE COOKIE
function setLanguageCookie() {
var expire = new Date();
expire = new Date(expire.getTime() + 7776000000);
document.cookie = "Language=Language; expires=" + expire;
}
// THIS IS FOR THE BURGER MENU TOGGLE
$(".dropbtn").click(function() {
$(this).next(".dropdown-content, .items").stop().slideToggle(500);
});
// If you click outside dropdown - close dropdown
var $menu = $('.dropdown');
$(document).mouseup(function(e) {
if (!$menu.is(e.target) && $menu.has(e.target).length === 0) {
$('.dropdown-content').hide();
}
});
$("#dd-content a").click(function(e) {
e.preventDefault();
var text = $(this).text();
var img = $(this).find('img').clone(true);
$('.dropbtn .lang').text(text);
$('.dropbtn img').replaceWith(img);
$("#dd-content a").removeClass('hide');
$(this).addClass('hide');
setLanguageCookie();
});
});

Answer 1

如果你是一个标签是一个真正的链接，那么你应该添加一个 preventDefault 调用到你的点击事件。 它将阻止在您设置 cookie 之前执行默认链接函数。

function setLanguageCookie() {
var expire=new Date();
expire=new Date(expire.getTime()[phone]);
document.cookie="Language=Language; expires="+expire;
}
// THIS IS FOR THE BURGER MENU TOGGLE
$(".dropbtn").click(function() {
$(this).next(".dropdown-content, .items").stop().slideToggle(500);
});
// If you click outside dropdown - close dropdown
var $menu = $('.dropdown');
$(document).mouseup(function(e) {
if (!$menu.is(e.target) && $menu.has(e.target).length === 0) {
$('.dropdown-content').hide();
}
});
$("#dd-content a").click(function(e) {
e.preventDefault(); // changes are HERE <--
var text = $(this).text();
var img = $(this).find('img').clone(true);
$('.dropbtn .lang').text(text);
$('.dropbtn img').replaceWith(img);
$("#dd-content a").removeClass('hide');
$(this).addClass('hide');
setLanguageCookie();
});

工作小提琴。

您必须在页面加载时获取cookie并将其设置为默认值，例如：

function getCookie(cname) {
var name = cname + "=";
var decodedCookie = decodeURIComponent(document.cookie);
var ca = decodedCookie.split(';');
for(var i = 0; i <ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') {
c = c.substring(1);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}
//GET LANGUAGE COOKIE
function getLanguageCookie() {
var lang = getCookie('Language') != ""?getCookie('Language'):"EN";
$('#dd-content').hide();
$("#dd-content a:contains('"+lang+"')").click();
}
//SET LANGUAGE COOKIE
function setLanguageCookie(Language) {
var expire=new Date();
expire=new Date(expire.getTime()[phone]);
document.cookie="Language="+Language+"; expires="+expire;
}
// THIS IS FOR THE BURGER MENU TOGGLE
$(".dropbtn").click(function() {
$(this).next(".dropdown-content, .items").stop().slideToggle(500);
});
// If you click outside dropdown - close dropdown
var $menu = $('.dropdown');
$(document).mouseup(function(e) {
if (!$menu.is(e.target) && $menu.has(e.target).length === 0) {
$('.dropdown-content').hide();
}
});
$("#dd-content a").click(function() {
var text = $(this).text();
var img = $(this).find('img').clone(true);
$('.dropbtn .lang').text(text);
$('.dropbtn img').replaceWith(img);
$("#dd-content a").removeClass('hide');
$(this).addClass('hide');
setLanguageCookie(text);
});
getLanguageCookie();
