出现时如何从弹出窗口获取文本值？

Question

我想从弹出窗口中获取文本值。当我们垂直向下滚动页面时，将显示此弹出窗口。这是代码段

<div class="talk-button animated slideInUp in">
    <a type="button">
    <span class="hidden">Would you like to talk to us about this article?</span>
    </a>
</div>

和我的JavaScript

var listen = "Would you like to talk to us about this article?"; 
var bodytext = $(".hidden").text(); 

if (listen == bodytext) { 
   console.log("bodytext", bodytext); 
   alert("Value is " + bodytext); 
}
