<script type="text/javascript" language="JavaScript">
<!-- 
function CheckValidation() {
var errormessage = new String();
 
if(WithoutContent(document.add.sprice.value))
    { errormessage += "\n\n\"PRICE\" still Empty."; }
if(WithoutContent(document.add.spropadd.value))
    { errormessage += "\n\nPROPERTY ADD still Empty."; }
if(WithoutSelectionValue(document.add.sbed))
    { errormessage += "\n\nBED list still Empty."; }
 
if(errormessage.length > 2) {
    alert('NOTE:' + errormessage);
    return false;
    }
return true;
 
function WithoutContent(ss) {
if(ss.length > 0) { return false; }
return true;
}
 
function WithoutSelectionValue(ss) {
for(var i = 0; i < ss.length; i++) {
    if(ss[i].selected) {
        if(ss[i].value.length) { return false; }
        }
    }
return true;
}

hi ...

to test for a numeric value you may use javascripts isNaN() (isNotaNumber) method:

var foo = '12345.56';
var bar = '12345gh';
 
// test will be false
var test = isNaN(foo);
 
// test1 will be true
var test1 = isNaN(bar);
 

kind regards ...

U also can do this by stop processing the non-numeric character.

function validateNumeric()
{
 if(event.keyCode >=48 && event.keyCode <= 57);
 else event.keyCode = 0; //Stop processing the non-numeric character.
}
//Mind it event.keyCode ..... this is IE specific and i hope u know for others.
 

Try it.
Best of luck.

Kind regards,
