树莓派 - Flask服务器使用JQuery不工作离线（在线工作） [英] Raspberry Pi - Flask Server using JQuery not working Offline (Online it works)
问题描述
< pre class =snippet-code-html lang-html prettyprint-override ; script src =http://code.jquery.com/jquery-1.9.1.min.js>< / script>
现在我想让它脱机工作，我尝试了很多在这个网站的其他问题的解决方案，但我不能让它工作远。
我尝试下载JQuery，并放在相同的文件夹，并在代码中引用它，但没有成功。这是我以为会的。
< script src = jquery-1.9.1.min.jstype =text / javascript>< / script>
我确保把相同的名称和文件夹，尝试子文件夹，有和没有/，但没有任何工作。
目前我也在使用在线css（图片），但是我试着在测试离线JQuery的时候删除它。我只想让JQuery离线工作，这样我就可以完成这个页面。
再次，我是一个新手，所以我很抱歉，提前感谢您的帮助。 / p>
下面是完整的HTML文件，它可以很好的在线工作，它有一些葡萄牙语，但是它们并不重要，因为问题只是在本地加载Jquery。再次感谢您的关注。

尝试创建一个静态文件夹，它将托管所有js和其他静态文件，如下所示：
code> static /
- js /
- css /
- ...
现在，将 jquery 文件放在 js / 文件夹中，并在您的
url_for（'static'，filename ='js / jquery-1.9.1.min.js'）
在您的模板中，您将拥有：
< script src ={{url_for（'static'，filename ='js / jquery-1.9.1.min.js'）}}type =text / javascript> ;< /脚本>
I'm a beginner and I have what should be an easy problem to solve. However, after researching many forums and trying the technical solution, I could not make the code to work offline, but it does work just fine loading JQuery online. Let me start explaining my work so far.
I used Flask to create an application so I could manipulate an inspection robot using smartphone app or navigator (Raspberry local host). I wrote 2 codes, the Python server and HTML client. It works just fine online, getting the JQuery library as it follows:
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
Now I want to make it to work offline and I tried many solutions given in other questions in this website, but I just could not make it work so far. I tried downloading the JQuery and placing in the same folder and referencing it in the code with no success. This is what I thought it would be.
<script src="jquery-1.9.1.min.js" type="text/javascript"></script>
I made sure to put the same name and folder, tried subfolder, with and without the "/", but nothing is working.
For the moment I`m using also online css (for images), but i tried removing it too while I was testing the offline JQuery. I just wanna get JQuery to work offline so I can finish the page.
Again, I`m a newbie, so I apologize and thank you in advance for your help.
Here is the full HTML file that does work just fine online, it has some portuguese but they don`t matter since the problem is just loading Jquery locally. Again, thank you for the attention.

Try to create a static folder that will host all your js and other static files like below:
static/
- js/
- css/
- ...
Now, put your jquery file in js/ folder and use the following in your template:
url_for('static', filename='js/jquery-1.9.1.min.js')
In your template, you will have:
<script src="{{ url_for('static', filename='js/jquery-1.9.1.min.js') }}" type="text/javascript"></script>
