Hello I have a few formelements that all trigger the same action:

$this->lst1Object->AddAction(new QClickEvent(), new QAjaxAction('functionname'));
$this->lst2Object->AddAction(new QClickEvent(), new QAjaxAction('functionname'));
$this->lst3Object->AddAction(new QClickEvent(), new QAjaxAction('functionname'));


protected function functionname($strFormId, $strControlId, $strParameter) {

}

How can I do these 2 things:

- Identify which element was calling the function?
- Pass a parameter to the function?

Resolved, see below.

Regards,
tronics

-Identify which element was calling the function?
Works very well:

protected function GeneratePersonAnteil($strFormId, $strControlId, $strParameter) {
$this->txtKommentar->Text=$this->GetControl($strControlId)->SelectedValue;

- Pass a parameter to the function?
Works very well:

$this->lstRating->ActionParameter = $intUserId.','.$intContentId;
$this->lstRating->AddAction(new QChangeEvent(), new QAjaxControlAction($this, 'lstRating_Change()'); 


public function lstRating_Change($strFormId, $strControlId, $strParameter) {
list($intUserId, $intContentId) = split(',', $strParameter);
}

Interesting: If you want to use the same Ajaxaction for a checkbox that triggers updates you can also use the property ->ControlId and hand it manually over to the checkbox action parameters.

So you can chill out without duplicating too much coode.

$this->lstTTObject->AddAction(new QClickEvent(), new QAjaxAction('GeneratePersonAnteil'));    
    
$this->chkTTCheckSonstiges->ActionParameter 
   = "lala,".$this->lstTTObject->ControlId;            

$this->chkTTCheckSonstiges->AddAction(new QClickEvent(), new QAjaxAction('GeneratePersonAnteil'));        






protected function GeneratePersonAnteil($strFormId, $strControlId, $strParameter) {
           
list($whatever,$strControlIdOverride) = split(',', $strParameter);
    

$aktuellePerson=$this->GetControl($strControlIdOverride)->SelectedValue;
//instead of $aktuellePerson=$this->GetControl($strControlId)->SelectedValue;

...

}

All the best,
tronics
