Previewer Hooks – gfpdf_previewer_auto_refresh_delay

Description

This filter allows you to change the default delay/timeout period before the Previewer auto-refreshes after a form change is detected.

Arguments

The following arguments are passed to functions that use this hook:

delay | int

• The time to wait in milliseconds before the previewer is refreshed.
• The default delay is 1000ms / 1 second

formId | int

• the current form ID the Previewer field is included

fieldId | string

• the ID of the current Previewer field

Usage

This example increases the delay/timeout from 1 second to 5 seconds:

gform.addFilter('gfpdf_previewer_auto_refresh_delay', function(delay, formId, fieldId) {
  return 5000;
}, 10, 3);

You can also limit the filter to a specific form:

gform.addFilter('gfpdf_previewer_auto_refresh_delay', function(delay, formId, fieldId) {
  if(formId === 5) {
    return true;
  }

  return 5000;
}, 10, 3);

Or a specific form field:

gform.addFilter('gfpdf_previewer_auto_refresh_delay', function(delay, formId, fieldId) {
  if(formId === 5 && fieldId === '7') {
    return true;
  }

  return 5000;
}, 10, 3);

Install

The Javascript code needs to be included on the same page as your form. A quick way to do this is to add a HTML field to your form and then place the code snippet inside the <script type="text/javascript"></script> tags.
