Hi Rodney Myers,
Thank your answer. I did what you said. But when I check the length of the
checkbox. It still show undefined instead of 1. Why?
Can you help me again?
Thanks.
Abe Liu
I have the codes as following,
.
.
function display_checkQty() {
var tot = 0;
var val = 0;
alert("sel-length= "+placeOrder.sel.length);
.
.
}
.
.
if (rsa.length == 1) {
%>
<td align="center" bordercolor="#FFFFFF" width="44"
height="15" <%= bgc %>><input type="checkbox" name="sel"
value="<%=tknAndUnits%>" onClick="display_checkQty()"></td>
<%
} else {
%>
<td align="center" bordercolor="#FFFFFF" width="44"
height="15" <%= bgc %>><input type="radio" name="sel"
value="<%=tknAndUnits%>" onClick="display_radioQty()"></td>
<%
}
