Hi Razlie,

Just add the function name in the "Element identifier" box and define teh function in a JavaScript element

Hi Max,

I must be doing something wrong because I have tried to do this and it didn't work. I tried the function name with and without brackets "()" and neither worked.

My JS code is in a custom JS code in the designer tab but I have also tried it with the script on a custom code action in the setup tab.

Thank you for your time.

Best regards,
Joao Serina

Hi Joao,

The function name should be in the "Element identifier" box without brackets and the function should be defined in a JavaScript element:

function xyz(){
alert(123);
}

This does not work ?

Sorry for the late reply,

I didn't test it yet but I was calling a function that was encapsulated in a jQuery call like:

(function($)
{
    $(document).ready(function () {
        
    });

    function MyFunction() 
    {
        alert("test");
      }

})(jQuery);

So this was probably the problem.

Thank you very much for you quick reply and once again I appologuise for the delayed reply.
