大家好。这是我的简单窗口。已经3天努力改变S.T.E.A.M.实验室文本到浮动类中的其他文本，单击一个。如果可能将此结果保存在cookie中。更多详细信息更多详细信息更多详细信息（对不起这是stackoverflow，他们需要更多详细信息）

您必须向浮动元素添加单击侦听器并将文本保存到链接。为了设置cookie，我使用了hier vanilla JS，但你也可以使用这个http://en.cppreference.com/w/cpp/io/basic_istream/readsome

＆＃13; 
$(document).ready(function(){
    $(".link").click(function(){  // when .link clicked 
        $(".elem").toggle(); // toggle .elem visibility 
    });
    $('.floating').click(function(evt){
        evt.preventDefault();
        $('.link').text(event.target.textContent);
        // document.cookie = "cookiename=event.target.textContent";  
    });
});
jQuery(function($){
	$(document).mouseup(function (e){ 
		var div = $(".link"); 
		var second = $('.elem');
		var close = $('.close');
		if (!div.is(e.target) && (second.has(e.target).length == 0 || close.is(e.target))) {  
			second.hide(); 
		}
	});
});

答案 1 :(得分：0)

第1步：将点击事件添加到区域下的a标记。

步骤2：在此单击事件处理程序上获取作为主题的单击元素的内部文本 - 并存储在变量中以供显示并存储在cookie中。

步骤3：编写一个cookie保存函数，该函数接受一个字符串参数，并在步骤2中调用，传入主题名称以保存在cookie中。

 $("body").on("click" "div.regions a", function(e) {
     // Your code here that fetches the event.target.innertext or some such
    var txt = $(e.target).text(); // sample code not tested
    SetCookie(txt);
    SetStemLabText(txt) 
});

 SetCookie(txt) {
  $.cookie("Subject", text);
 }

 SetStemLabText(txt) {
  $('.link').text(txt)
 }
