After following a tutorial, my client side form validation didnt work. As in nothing. It’s like I never wrote any validation code. :S I don’t know what I did wrong…
Here:
[code=php]
<script language=”JavaScript” type=”text/javascript”>
function checkForm()
{
var cby, cproduct, cprice, cdesc, cname, ccontact;
with(window.document.post)
{
cby = by;
cproduct = product;
cprice = price;
cdesc = desc;
cname = name;
ccontact = contact;
}
if(trim(cby.value) == ”)
{
alert(‘Indicate whether you are Buying or Selling’);
cby.focus();
return false;
}
else if(trim(cproduct.value) == ”)
{
alert(‘Please Enter the Product Name’);
cproduct.focus();
return false;
}
else if(trim(cprice.value) == ”)
{
alert(‘Please indicate the Price of the product’);
cprice.focus();
return false;
}
else if(trim(cdesc.value) == ”)
{
alert(‘Please enter a short description about the product’);
cdesc.focus();
return false;
}
else if(trim(cname.value) == ”)
{
alert(‘Please enter the name of the person to be contacted’);
cname.focus();
return false;
}
else if(trim(ccontact.value) == ”)
{
alert(‘Please enter the contact details, such as: cell number, email add, etc.’);
ccontact.focus();
return false;
}
}
function trim(str)
{
return str.replace(/^s+|s+$/g,”);
}
</script>
