我正在尝试添加一个点击后会打开的小“触发框”。它曾经工作过一段时间，但我不确定现在到底出了什么问题。

我学了一点 HTML 和 CSS，所以我了解这些部分的内容，但我几乎不知道 Javascript。所以脚本选择器中的所有内容对我来说都是新的；其他人在线提供了它，我正在努力理解它。阅读语法，我想我知道发生了什么，但我仍然不知道问题到底是什么。

这是我的代码。是的，它都在 1 个 HTML 文件中，因为这仅适用于 1 页。

<!DOCTYPE html>
<html>
<head>
<title> This is the Title </title>
<style type="text/css">
html, body { color:#666; font:"Times New Roman", Times, serif; }
        h1 { font-size:36px; color:#333; margin:0 0 15px 0; padding:0 0 15px 0; border-bottom: solid 1px #e1e1e1; }
        .awesomeBox { border:solid 1px #cacaca; box-shadow: 0 0 3px #bbb; padding:15px; margin:20px; width:400px; }
        .trigger { cursor:pointer; }

        /* this is all you need to make the hidden box hidden :) */
        .hiddenBox { display:none; }

        /* we put a little style to the trigger */
        .box { position:relative; }
        .box .trigger { font-size:12px; background:#cacaca; padding:5px 10px; color:#fff; text-decoration:none; position:absolute; bottom:-42px; right:0; }
        .box .hiddenBox { background:#f9f9f9; color:#000; padding:10px; margin:10px; }
</style>

<script src = "//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>

$(function() { 

            $(".trigger").on("click", function() { 
                $(".hiddenBox").toggle();                                                   
            });             
        });
</script>

</head>

<body>
<div class="awesomeBox">

    <h1 class="trigger">Le awesome Page</h1>

    <div class="box">The area where you could type a lot of text but also want to hide some text<br>

        <p>So, user will press the read more button.</p> <a href="#" class="trigger">Read more &raquo;</a> 

        <div class="hiddenBox"> 

            <p>A lot of text in this hidden box and ...
            a lot 
            alot more
            fsdfsd
            </p>

            <img src="https://www.google.com/images/srpr/logo4w.png" width="100%" /> 
       </div>             
    </div>        
</div>    
</body>
</html>

It works just fine for me, see here: http://jsfiddle.net/Ex6pK/

Try viewing this page in Google Chrome, Right click on any part of the visible page, and Inspect Element, look for Javascript errors there.

I suspect that perhaps

    $(function() { 

        $(".trigger").on("click", function() { 
            $(".hiddenBox").toggle();                                                   
        });             
    });

is being called before Jquery is loaded
