How to set corectly the AJAX call for change the value in a field

Question

I would like to know how to set a AJAX call following an trigger call by a field. In particular what I have to insert in the new page for the AJAX call. It is clear how to set trigger e listener advance, but not clear how to change the value in the field when the trigger is on. I am using CF8

Many thanks

Hi Maurizio

Please check this:

The AJAX will load the result from "page5" and will call a function called "set_value" after the result arrives, this function will get 2 parameters:

The AJAX result, this will be whatever string or HTML you print in page5
The field object which has the listener

So you can add a JavaScript view to your form:

function set_value(result, field){
field.value = result
}

And this will set the value of the field to the AJAX result
