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

问题描述

我想在点击后点击一个cookie，以便在页面刷新后保持我的选择活动，并且我在下面有以下代码：

I want to put a cookie on click to keep my selection active after the page refresh and I have this code below:

我尝试了不同的方法，但我可以没有成功。我是javascript或jquery的菜鸟。

I have tried different methods but I can't make it happen. I am a noob at javascript or jquery.

看看我到现在为止做了什么。我有一个函数，我想设置cookie，然后我在点击事件上调用该函数。

Look what I've tried till now. I have a function where I want to set the cookie and then I call that function on click event.

$(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();
  });

});

Working fiddle.

您必须在页面加载时获取Cookie并将其设置为默认值，如：

You've to get the cookies when the page loads and set it as the default like :

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();
