Create HTML button to run Python Script
提问by user2125116
I am trying to create a button on a webpage quad_relay.html
我正在尝试在网页 quad_relay.html 上创建一个按钮
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.o$
<html xmlns="http://www.w3.org/1999/xhtml">
</script>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<h1>Quad Web Relay</h1>
<div>Relay 1:
<input type="button" value="Toggle" id="toggle1" />
</div>
</body>
</head>
</html>
When that button is clicked I want it to run a python script set_gpio.py
单击该按钮时，我希望它运行 python 脚本 set_gpio.py
def set_pins_high():
fp = open("/sys/class/gpio/gpio"+pin+"/value","w")
fp.write(str(1))
fp.close()
def set_pins_low():
fp1 = open("/sys/class/gpio/gpio"+pin+"/value","w")
fp1.write(str(0))
fp1.close()
for pin in pins:
for x in range (0,2):
set_pins_high()
time.sleep(0.5)
set_pins_low()
time.sleep(0.5)
The webpage is located on a lighttpd server running Django. I have jQuery and AJAX installed, and I know they are the route that I need to take to accomplish this however everytime I try something it doesnt work.
该网页位于运行 Django 的 lighttpd 服务器上。我安装了 jQuery 和 AJAX，我知道它们是我需要采取的方法来实现这一点，但是每次我尝试一些东西时它都不起作用。

you have to do some modifications:
你必须做一些修改：
In your HTML file:
在您的 HTML 文件中：
<div>Relay 1:
<form action= '{% url my_view_name%}' method="POST">
<input type="submit" value="Toggle" id="toggle1" />
</form>
</div>
in urls.py
在 urls.py 中
url(r'whatever^$', 'core.views.my_view',name='my_view_name'),
In views.py:
在views.py中：
def my_view(request):
if request.method == 'POST':
import set_gpio
#Do your stuff ,calling whatever you want from set_gpio.py
return #Something, normally a HTTPResponse, using django
