How To Get Data In Flask From Ajax Post
I want to retrieve the data from the variable 'clicked' so I can use it in SQL queries in Flask. JQuery $(document).ready(function(){ var clicked; $('.favorite').click(function
Solution 1:
You can compose your payload in your ajax request as so:
$(document).ready(function(){
var clicked;
$(".favorite").click(function(){
clicked = $(this).attr("name");
$.ajax({
type : 'POST',
url : "{{url_for('test')}}",
contentType: 'application/json;charset=UTF-8',
data : {'data':clicked}
});
});
});
In your flask endpoint, you can extract the value as follows:
@app.route('/test/', methods=['GET','POST'])deftest():
clicked=Noneif request.method == "POST":
clicked=request.json['data']
return render_template('test.html')
Solution 2:
I used the best answer but i found a bad request error. I solve this error as below:
1- remove this line from ajax request:
contentType:'application/json;charset=UTF-8',
2- Access to data by request.form instead of request.json.
The Javascript part will similar to this:
$(document).ready(function(){
var clicked;
$(".favorite").click(function(){
clicked = $(this).attr("name");
$.ajax({
type : 'POST',
url : "{{url_for('test')}}",
data : {'data':clicked}
});
});
});
Flask part:
@app.route('/test/', methods=['GET','POST'])deftest():
clicked=Noneif request.method == "POST":
clicked=request.form['data']
return render_template('test.html')
Solution 3:
At your flask app end-point , you can define method to retrieve GET/POST data like this :
from flask_restful import reqparse
defparse_arg_from_requests(arg, **kwargs):
parse = reqparse.RequestParser()
parse.add_argument(arg, **kwargs)
args = parse.parse_args()
return args[arg]
@app.route('/test/', methods=['GET','POST'])deftest():
clicked = parse_arg_from_requests('data')
return render_template('test.html' , clicked=clicked)
