code ajax :

<script type="text/javascript">
    $(function(){
       $('.btn').click(function(){
           var $cname = $('input[name="cname"]').val();
           var $cemail = $('input[name="cemail"]').val();
           var $curl = $('input[name="curl"]').val();
           var $text = $('textarea[name="comment"]').val();
           var $res = $('#res');
           $.ajax({
               url:'/tpush/pl',
               data: $('form').serialize(),
               type: 'POST',
               dataType:'json'
           }).done(function (data) {
               if (!data.r){
                   $res.html(data.rs);
               }else{
                   $res.html(data.error);
               }
           });
       });
    });
</script>

code python

@web.route('/tpush/pl',methods=['POST'])
def web_tpush():
    cname = request.form['cname']
    cemail = request.form['email']
    curl = request.form['curl']
    #ctext = request.form['ctext']
    print(cname,cemail,curl)
    error = None
    if len(cname) < 2:
        error = '666'
    if len(cemail) < 5:
        error = '777'
    if error is not None:
        return jsonify({'r':1,'error':error})
    return jsonify({'r':0,'rs':ok})

Je clique sur Soumettre et passe à /tpush/pl

Answer 1

cemail = request.form['email']

changé en

cemail = request.form['cemail']

De plus, votre formulaire est soumis à une publication par défaut. Si vous souhaitez le gérer vous-même, n'ajoutez pas d'actions au formulaire.

$('.btn').click(function(event){
  event.preventDefault();
});
