Answer» Consider the application which includes a folder named “media” with index.html and Jquery plugin, and a file with AJAX implementation. Let us consider the name of the file as “ajax_app.py”
ajax_app.py
import cherrypy
import webbrowser
import os
import simplejson
import sys
MEDIA_DIR = os.path.join(os.path.abspath("."), u"media")
class AjaxApp(object):
@cherrypy.expose
def index(self):
return open(os.path.join(MEDIA_DIR, u'index.html'))
@cherrypy.expose
def submit(self, name):
cherrypy.response.headers['Content-Type'] = 'application/json'
return simplejson.dumps(dict(title="HELLO, %s" % name))
config = {'/media':
{'tools.staticdir.on': True,
'tools.staticdir.dir': MEDIA_DIR,}
}
def open_page():
webbrowser.open("http://127.0.0.1:8080/")
cherrypy.engine.subscribe('start', open_page)
cherrypy.tree.mount(AjaxApp(), '/', config=config)
cherrypy.engine.start()
The class “AjaxApp” redirects to the web page of “index.html”, which is included in the media folder.

The function for AJAX is included within <script> tags. Consider the application which includes a folder named “media” with index.html and Jquery plugin, and a file with AJAX implementation. Let us consider the name of the file as “ajax_app.py” ajax_app.py
import cherrypy
import webbrowser
import os
import simplejson
import sys
MEDIA_DIR = os.path.join(os.path.abspath("."), u"media")
class AjaxApp(object):
@cherrypy.expose
def index(self):
return open(os.path.join(MEDIA_DIR, u'index.html'))
@cherrypy.expose
def submit(self, name):
cherrypy.response.headers['Content-Type'] = 'application/json'
return simplejson.dumps(dict(title="Hello, %s" % name))
config = {'/media':

}
def open_page():
webbrowser.open("http://127.0.0.1:8080/")
cherrypy.engine.subscribe('start', open_page)
cherrypy.tree.mount(AjaxApp(), '/', config=config)
cherrypy.engine.start() The class “AjaxApp” redirects to the web page of “index.html”, which is included in the media folder. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
