首先，我需要了解为什么cookie不在我的浏览器中设置。我拿了另外一个脚本并从我的openserver运行它，一切都很好，但如果我写这样的代码

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<!DOCTYPE html>
<html>
<head>
	<title>Any project</title>
	<meta http-equiv="Content-Type" content="text/html"; charset="utf-8" />
</head>
<body>
<div class="wrapper">
	<a class="link" href="#">Countries</a>
	<div class="elem">
		<p class="title">Choose youre locality </p><i class="close" >X</i>
		<div class="regions">	
			<a class="floating" href="#">Kiev</a>
			<a class="floating" href="#">Baku</a>
			<a class="floating" href="#">Paris</a>
			<a class="floating" href="#">London</a>
			<a class="floating" href="#">Moscow</a>
			<a class="floating" href="#">Amsterdam</a>
			<a class="floating" href="#">Rome</a>
			<a class="floating" href="#">Dubai</a>
			<a class="floating" href="#">Berlin</a>
		</div>
		<p class="otherregion">Or choose another one:</p>
		<form>
			<input class="edit" type="text" name="add" placeholder="Начните вводить название">
		</form>


</div>
<script type="text/javascript" src="jquery/jquery-3.2.1.min.js"></script><!-- This is my cookie  -->
<script type="text/javascript" src="script.js"></script>
<script type="text/javascript" src="cookie.js"></script>
</body>
</html>

警告显示空字符串。在开发者工具中，Chrome显示空行。接下来我需要点击并选择（点击）它必须保存在cookie或localstorage中的国家/地区列表中的任何国家/地区。如果有可能请告诉我两个版本，如果你刷新浏览器或关闭浏览器它必须在那里。而不是国家必须是你的选择。请任何人帮助已经周无法解决这个问题。

Answer 1

使用localStorage。

$('.floating').click(function(e){
   e.preventDefault();
   $('.link').text($(this).html());
   localStorage.setItem('cookiename',$(this).html());
});

然后检索它

 var value = localStorage.getItem('cookiename');

Answer 2

语法不正确。 document.cookie = "cookiename=" + event.target.textContent;

理想情况下，您也希望设置过期日期，否则在浏览器关闭后Cookie将不存在。

var dt = new Date();
dt.setTime(dt.getTime() + (<duration in ms>);
document.cookie = "cookiename=" + event.target.textContent + ";expires=" + dt.toUTCString();

如何在cookie或localstorage中保存点击的结果
