Menu
My goal is to return the button's ID to the python script and use it to control stuff the script is doing. After trying a whole evening and basically going through it with try and error I am a little frustrated with it, because there must be something simple I oversaw.
I tried to reduce stuff as much as possible but the button will always return a None inrequest.form.get("button") which leads to an Error 400. As I am not to firm with jQuery I tried a lot there but nothing ever delivered somethign other than a None.
Can anybody help me?
from flask import Flask, render_template_string, request
app = Flask(__name__)
@app.route('/')
def index():
return render_template_string('''
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-2.1.4.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('input').on('click', function() {
$.ajax({
url: "{{ url_for('data_post') }}",
method: "POST",
data: JSON.stringify($(this).attr("id")),
contentType: 'application/json;charset=UTF-8',
success: function(data) {
console.log(data);
}
});
});
});
</script>
</head>
<body>
<input type="submit" id="testvalue" name="button" value="button">
</body>
</html>
''')
@app.route('/data', methods=['GET', 'POST'])
def data_post():
text = request.form.get("button")
return text
if __name__ == '__main__':
app.run(debug=True)
400
Change data_post function to:
@app.route('/data', methods=['GET', 'POST'])
def data_post():
text = request.data
return text
and everything should be fine.
