Javascript - What is wrong with this expression?
I have the following snippit of an expression im making that i cannot get to work... its a function that is called onsubmit of a form.. note that the title and surname works, after that nothing
function checkit(_formname)
{
if (_formname.lsttitle.selectedIndex == 0)
{
alert ("Please select a title");
return false;
}
else if (_formname.txtsurname.value.length == 0 )
{
alert("Surname is empty!");
_formname.txtsurname.focus();
return false;
}
else if (checkone(_formname.txtsurname.value) != true)
{
alert("Surname is "+ _formname.txtsurname.value+" contains numbers - only uppercase and lowercase letters permitted");
_formname.txtsurname.focus();
return false;
}
else if (_formname.txtname.value.length == 0 )
{
alert("Name is empty!");
_formname.txtname.focus();
return false;
}
Sorry to say, but this is only a part of the code.... the code goes on to validate 10 different fields. Full code is:
function checkit(_formname)
{
if (_formname.lsttitle.selectedIndex == 0)
{
alert ("Please select a title");
return false;
}
else if (_formname.txtsurname.value.length == 0 )
{
alert("Surname is empty!");
_formname.txtsurname.focus();
return false;
}
else if (checkone(_formname.txtsurname.value) != true)
{
alert("Surname is "+ _formname.txtsurname.value+" contains numbers - only uppercase and lowercase letters permitted");
_formname.txtsurname.focus();
return false;
}
else if (_formname.txtname.value.length == 0 )
{
alert("Name is empty!");
_formname.txtname.focus();
return false;
}
else if (checkone(_formname.txtname.value) != true)
{
alert("Name is "+ _formname.txtName.value+" contains numbers - only uppercase and lowercase letters permitted");
_formname.txtname.f

Remove the else part of all the ifs. It is not needed as the return statement will terminate the function.
Also check the spelling of the field txtname on the form. The name is case sensitive.
Have fun.

Is checkone a previously declared function and what does it output?
Try checking that.
