In this article, we will demonstrate how to retrieve values from a subform. We'll use a simple app as an example, where we read the value from the subform and set it in a form field.

Make sure to remember the Form ID of your subform, it will be necessary for your Custom HTML.

Custom HTML
This is the Javascript code that reads the value of the subform and sets the field value.
Javascript
<script>
$(document).ready(function(){
selectmain = $(FormUtil.getField("field1")); //Get ID of subform
selectmain.on("change",function(){
setTimeout(function(){
my_name = $("#field2_subform_name"); //Get subform value
my_country = $("#field2_subform_country");
my_date = $("#field2_subform_date");
var field1 = FormUtil.getField("field3"); //Get field of form
var field2 = FormUtil.getField("field4");
$(field1).val(my_name.val()); //Set field to value of subform
$(field2).val(my_country.val());
},100);
});
})
</script>
