Send 'POST' request without submit event

Event after which i am sending ajax is not submit. I even don't have sumbmin button. This is part of my jquery:

              var description_data = $('#description_form').serialize();
              alert(description_data)
              $.ajax({                  
                  url: '/accounts/profile/add_description/',
                  type: 'POST',
                  data: description_data,
                  success: function(data){alert('ok')}
              });

and my view.py

def add_description(request):
    if request.is_ajax() or request.method == "POST":
        form = DescriptionForm(开发者_StackOverflowrequest.POST, prefix="description")
        if form.is_valid():
            user = request.user
            profile = user.get_profile()                
            description = form.cleaned_data['content']
            profile.description=description
            profile.save()
            response = HttpResponse()
            response['Content-Type'] = "text/javascript"
            response.write(serializers.serialize('json', [profile], fields=('description')))
            return response
        else:
            return HttpResponse('form invalid')    
    else:
        return HttpResponse('error')

Ajas is sent not by submit event, but when it is send like that there request.is_ajax() or request.method=="POST" return False. How can i make it working?

You probably need to call preventDefault, to stop the click event submitting the form before it runs the Ajax request.

$('#myButton').click(function(e) {
  e.preventDefault;
  //Your code from above
});
