我的javascript赢了'；t装在python烧瓶中,javascript,html,flask,Javascript,Html,Flask,我正在尝试将一段javascript函数性加载到index.html中然而，当我在flask中加载时，它似乎不起作用。我不是JS专家，但我假设它是JS错误的，因为我已经确保所有东西都在正确的目录中，并且加载正确。请看看我做错了什么 base.html <!doctype html> <html> <head> <title>Flask-Mobility example</title> </head> <body&

我正在尝试将一段javascript函数性加载到index.html中然而，当我在flask中加载时，它似乎不起作用。我不是JS专家，但我假设它是JS错误的，因为我已经确保所有东西都在正确的目录中，并且加载正确。请看看我做错了什么

base.html

<!doctype html>
<html>
<head>
  <title>Flask-Mobility example</title>
</head>
<body>
  {% block content %}
  {% endblock %}
</body>
</html>
app\static\index.js

将

脚本

标记移到底部

如果写在上面，它们就没有什么可参考的了。例如，

$（“.next”）

实际上没有匹配任何内容，因为尚未创建具有该类的元素。

| FlaskApp
----|烧瓶应用程序
--------|模板
-----------html文件在这里
--------|静态
-----------css和javascript文件在这里

script type=“text/javascript”src=“{url\u for（“static”，filename=“javascript.js'）}”

您可以包含

base.html

模板吗？将其添加到主线程中。这就是我正在使用的代码笔。这个代码笔使用的是jQuery（和一个插件），我在你的代码中没有看到。它们在JS设置中：

//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.JS

和

//cdnjs.cloudflare.com/ajax/libs/jquery-easing/1.3/jquery.easing.min.JS

，我补充说，它似乎不起作用。{%block content%}{%endblock%}我把它放在底部，似乎不起作用。我还将其添加到base.html下。如果这些是您包含的脚本，它将无法工作。您没有包括jquery，代码笔中也没有提到jquery一页。只需按顺序添加jquery、jquery和您的索引，就行了！谢谢

{% extends 'base.html' %}
