从html代码调用python函数 [英] call python function from html code
问题描述
我现在正在使用Flask框架开发Google App引擎，我已经创建了具有不同控件的模板，我不需要从html调用python中的python函数，而我可以通过ajax脚本来捕获按钮触发，如下所示的html代码
I'm now working to develop google app engine using flask framework i have create a template with different control i need no to call function in python from my html where i catch the button trigger by ajax script the html code as follow
<html>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js" ></script>
<br>
<form action="" method="post" >
<div id ="par_input" ><table> <tr> <td><textarea id ="equation" rows="2" cols="60"></textarea> <input id ="insert" type="button" onclick="insert_fun()" value="Insert" > <!-- -->
</form>
</div>
<script type="text/javascript">
function insert_fun(){
//window.alert("Tariq work !");
$.ajax({
type: 'POST',
url: window.location.href + '/insert'
});
document.getElementById("equation").value = "{{ TARIQ_ID }}";
}
</script>
</html>
我的python代码是
and my python code is
from flask import Flask #import the Flask class.
from flask import make_response
from flask import render_template
from flask import request
from flask import session
from flask.kvsession import KVSessionExtension
from flask import abort
from flask import jsonify
from google.appengine.ext import webapp
from google.appengine.ext.webapp import template
APPLICATION_NAME='application test '
app = Flask(__name__)
@app.route('/', methods=['GET'])
def index():
"""Initialize a session for the current user, and render index.html."""
TARIQ_ID = 'inside index function'
# serving it.
response = make_response(
render_template('tariq.html',
APPLICATION_NAME=APPLICATION_NAME,
TARIQ_ID=TARIQ_ID))
response.headers['Content-Type'] = 'text/html'
return response
@app.route('/', methods=['POST'])
def insert(self = webapp.RequestHandler):
TARIQ_ID = 'In Python Code Function__INSIDE RESPONSE___===='
response = make_response(
render_template('tariq.html',
APPLICATION_NAME=APPLICATION_NAME,
TARIQ_ID=TARIQ_ID))
response.headers['Content-Type'] = 'text/html'
return response
class MyHandler(webapp.RequestHandler):
def get(self):
TARIQ_ID = 'In Python Code Function__INSIDE get===='
self.response.out.write(unicode(
template.render('tariq.html',
TARIQ_ID)))
def post(self):
TARIQ_ID = 'In Python Code Function__INSIDE post===='
self.response.out.write(unicode(
template.render('tariq.html',
TARIQ_ID)))
def main():#app.debug =真#app.run(host ='0.0.0.0'，port = 4567)#我们使用run()函数在我们的应用程序中运行本地服务器
def main(): #app.debug = True #app.run(host='0.0.0.0', port=4567) #we use the run() function to run the local server with our application
app = webapp.WSGIApplication([
(r'.*',MyHandler)], debug=True)
wsgiref.handlers.CGIHandler().run(app)
if __name__ == '__main__':
main()
但是python函数没有返回TARIQ_ID的更新值，也没有任何响应，请您帮忙
but the python function dose not return the updated value of TARIQ_ID also it dose not make any response please your help
推荐答案
我不了解Flask，所以这只是一个猜测，但是您需要更改吗:
I don't know Flask so this is just a guess, but do you need to change this:
@app.route('/', methods=['POST'])
def insert(self = webapp.RequestHandler):
对此:
@app.route('/insert', methods=['POST'])
def insert(self = webapp.RequestHandler):
