JAVASCRIPT removeRow() function

JAVASCRIPT removeRow() function

i would like to know the syntax for removing a row which was added by
appendchild. There is also a removechild but i am not sure how to operate.
Thank you! Luca
<input type="button" id='submitlink' value="ADD_AGENDA"

var temp ="

var yourDiv = document.getElementById('AGENDA');
