Open Child Form from parent form and prepopulate field in form javascript dataverse power apps

you can open a child table form and prepopulate field in child from parent record, use the below code.

Here I am opening student enrollment form in create mode with prepopulate student lookup and other details.

function openCreateFormAsDialogPrepopulateValue(context)
{
	//called from button so primary control is the formcontext
	var pageInput = {};

	var studentId = Xrm.Page.data.entity.getId();
	studentId = studentId.replace("{", "").replace("}", "");

	pageInput.createFromEntity = {
		entityType : "fbs_student",
		id : studentId,
		name : context.getAttribute("fbs_studentname").getValue()
	}
	pageInput.relationship = {
	attributeName: "fbs_student",
	namme: "fbs_fbs_studentenrollment_Student_fbs_student",
	relationshipType: 0,
	roleType: 1
	}
	pageInput.pageType = "entityrecord";
	pageInput["entityName"] = "fbs_studentenrollment";

	// Set default values for the enrollment form
	var formParameters = {};
	formParameters["fbs_name"] = "Enrollment for " + context.getAttribute("fbs_studentname").getValue();
	formParameters["fbs_coursestartdate"] = new Date(); 

	pageInput.data = formParameters;

	var navigationOptions = {
				target: 2,
				height: {value: 80, unit:"%"},
				width: {value: 70, unit:"%"},
				position: 1
			};

	// Open the form.
	Xrm.Navigation.navigateTo(pageInput,navigationOptions).then(
	function (success) {
	console.log(success);
	},
	function (error) {
	console.log(error);
	});
}
