javascript - 无法弄清楚如何调用ohsnap.js

我一直试图发出一个简单的通知“弹出窗口”，但我的阅读障碍是我的敌人。 （花了3个小时，我发现我写的是“ scr”而不是“ src”

该脚本本身是一个预先编写的脚本（http://justindomingue.github.io/ohSnap/）
这是我的html代码：

<!DOCTYPE html><html><head><meta charset=utf-8>


<link href="//my.site.se/css/ohsnap.css" rel="stylesheet" type="text/css" />

</head>
<body>

<div id="ohsnap"></div>


<script src= "//my.site.se/js/jquery-3.2.1.slim.js"></script>
<script src="//my.site.se/js/ohsnap.js"></script>

<script>
ohSnap('Oh Snap! I cannot process your card...');
</script>
</body>


最后的“脚本”是我最后一次调用ohsnap函数的尝试，但是我无法使其正常工作。

我已经检查了html代码，并确保css和脚本文件已“加载”。

这是ohsnap.js

    }

    // Generate the HTML
    var html = $('<div class="alert ' + color_markup + '">' + icon_markup + text + '</div>').fadeIn(options['fade-duration']);

    });

    setTimeout(function() {
        ohSnapX(html);
    }, options.duration);
}

 */
function ohSnapX(element, options) {
    defaultOptions = {
      'duration': 'fast'
    }

    options = (typeof options == 'object') ? $.extend(defaultOptions, options) : defaultOptions;

    if (typeof element !== "undefined") {
        element.fadeOut(options.duration, function() {
            $(this).remove();
        });
    } else {
        $('.alert').fadeOut(options.duration, function() {
            $(this).remove();
        });
    }
}


这是css文件：

/* ALERTS */
/* inspired by Twitter Bootstrap */

.alert {
  padding: 15px;
  margin-bottom: 20px;
  border: 1px solid #eed3d7;
  border-radius: 4px;
  position: absolute;
  bottom: 0px;
  right: 21px;
  /* Each alert has its own width */
  float: right;
  clear: right;
  background-color: white;
}

.alert-red {
  color: white;
  background-color: #DA4453;
}
.alert-green {
  color: white;
  background-color: #37BC9B;
}
.alert-blue {
  color: white;
  background-color: #4A89DC;
}
.alert-yellow {
  color: white;
  background-color: #F6BB42;
}
.alert-orange {
  color:white;
  background-color: #E9573F;
}


而且我猜我不需要附加jQuery;）

这也是我今天尝试的第五个脚本（只是尝试过的脚本已花费了5个小时以上），但它不仅会起作用。
我什至尝试阅读制造商主页的源代码，但是该解决方案对我不起作用（他使用按钮），我需要在检索页面时执行脚本。

有人遇到过这个吗？

最佳答案

1）您的第一个脚本标签未关闭:)

2）您不能在没有名称的情况下声明函数，只需在执行代码之前使用$(function(){ ... });等待页面完全加载即可。

3）您需要使用JQuery而不是JQuery Slim才能正确使用.fadeIn()函数。
