Thank you, now I use it, becouse I haven't form only variables (delFo,
delFac, delDir, delPr) in JavaScript:
view:
data = {fo : delFo, fac : delFac, direction : delDir, pr : delPr};
jQuery.ajax({
type: "POST",
url: "deleteCompetition",
data: 'data='+JSON.stringify(data),
cache: false,
success: function(response) {
alert("Deleted");
}
});
controller:
def deleteCompetition():
a = json.loads(request.vars.data)
i = 0
for b in session.prog_list:
if (b['fo']==a['fo'].encode('utf-8')) &
(b['fac']==a['fac'].encode('utf-8')) &
(b['dir']==a['direction'].encode('utf-8')) &
(b['prog']==a['pr'].encode('utf-8')):
del session.prog_list[i]
break
