Numeric validation

Hi,

The folloiwng code displays data in an asp form from database for updating purpose. I want to force user to enter a number (no decimals or negative or zeros) in the "QtyOut_<%=iLp%>" fields. Could anyone pls. help me?

Zero is allowed only if user selected the check boxes in the form "Del_<%=iLp%>".

          <%if not rst3.EOF then
               iLp = -1
               while not rst3.EOF
                    iLp = iLp + 1%>
                    <TR>
                         <TD width="40" height="1" align="center"><%=rst3.AbsolutePosition%></TD>
                         <TD width="150" height="1">
                              <INPUT name="PartNo_<%=iLp%>" ReadOnly value="<%=server.HTMLEncode(rst3("PartNo"))%>">
                         </TD>
                         <TD width="151" height="1">
                              <INPUT name="f_1_<%=iLp%>" value="<%=server.HTMLEncode(rst3("ProductName"))%>" readonly>
                         </TD>
                         <TD width="100" height="1">
                              <INPUT size=5 name="QtyOut_<%=iLp%>" value="<%=rst3("QtyOut")%>">
                              <input type="hidden" name="OldQtyOut_<%=iLp%>" value="<%=rst3("QtyOut")%>">
                              <input type="hidden" name="ROL_<%=iLp%>" value="<%=rst3("ROL")%>">
                         </TD>
                         <TD align="center">
                              <INPUT type="checkbox" name="Del_<%=iLp%>" value="True">
                              <INPUT type=hidden name="ID_<%=iLp%>" value="<%=rst3("ID")%>">
                         </TD>
                    </TR>
                    <%rst3.MoveNext
               Wend%>
               <tr>
                    <td colspan="5" align="right">
                         <input type="hidden" name="ItemCount" value="<%=iLp%>">
                         <input type="hidden" name="Action" value = "Update">
                    </td>
               </tr>
          <%end if%>

use this onblur event on your inputs:

<INPUT type="text" name="numeric" onblur='this.value=this.value.replace(/[^\d]*/gi,"");' />

Do you want the user to be able to type any character in the box and then it checks it on submit or do you want it to only allow 1-9 and maybe 0 in the box and all other characters don't work?

Hi,

I want to force user to enter numeric values in the "QtyOut_<%=iLp%>" fields.

It should be something like this;

function mySubmit(obj)
{
     var theForm=obj.form;
     var p1=/^col1_/;
     var num=/^[1-9]\d*/;
     var oldCol1= new Array();
     for(var i=0;i<theForm.elements.length;i++)
     {
          if(p1.test(theForm.elements[i].name))
          {
               if(theForm.elements[i].value!="" && theForm.elements[i+1].value=="")
               {
                    alert("Please enter a valid quantity");
                    theForm.elements[i+1].focus();
                    return false;

But if user seletected <INPUT type="checkbox" name="Del_<%=iLp%>" value="True"> then 0 is allowed.
