gform_post_render

Description

This jQuery hook is fired every time the form is rendered to allow custom jQuery to be executed. This includes initial form load, going to the next/previous page on multi-page forms, form rendered with validation errors, confirmation message displayed, etc.

Usage

<script type="text/javascript">

    jQuery(document).on('gform_post_render', function(event, form_id, current_page){

        // code to trigger on form or form page render

    });

</script>

Examples

This event is very useful when you wish you create a custom datepicker and enable AJAX for a form. Without this event, the default Gravity Form datepicker would be used if the form were reloaded due to validation errors. With this event, you can reinitialize your custom datepicker every time the form is rendered.

<script type="text/javascript">

    jQuery(document).on('gform_post_render', function(){

        // destroy default Gravity Form datepicker
        jQuery("#input_1_20").datepicker('destroy');

        // create new custom datepicker
        jQuery("#input_1_20").datepicker({ defaultDate: '+7d', minDate: '+7d', gotoCurrent: true, prevText: *, showOn: 'both', buttonImage: '/wp-content/plugins/gravityforms/images/calendar.png', buttonImageOnly: true });

    });

</script>
