}

javascrip:  function populatewoodid(){     var selectbox = document.getelementbyid('woodtype');      /* selected value of dropdown */     var woodheight = selectbox.options[selectbox.selectedindex].value;      /* selected value set input field */     document.getelementbyid('woodheight').value = woodheight;  } 

change option tag line :

<option value='<%=rs.getstring(1)+"#"+rs.getstring(2)+"#"+rs.getstring(3)+"#"+rs.getstring(4)+"#"+rs.getstring(5) %>'><%=rs.getstring(2) %></option> 

and in javascript :

function populatewoodid(){     var selectbox = document.getelementbyid('woodtype');      /* selected value of dropdown */     var woodprop = selectbox.options[selectbox.selectedindex].value;      /* selected value set input field */     var splitval=woodprop.split("#",5);     document.getelementbyid('woodheight').value = splitval[0];      document.getelementbyid('woodheight1').value = splitval[1];      document.getelementbyid('woodheight2').value = splitval[2];      document.getelementbyid('woodheight3').value = splitval[3];      document.getelementbyid('woodheight4').value = splitval[4]; //five different textboxes  }
