Adapt character validation function to also check length of field.

[uncleroydee]

I would like to adapt the following function, which I am already using, to also ensure the length of the field as 13 characters. The function currently checks that a field contains only numeric data and is called by onblur event handlers in the individual input fields.

<SCRIPT LANGUAGE=&quot;JavaScript&quot;>

<!-- Begin
function validate(field) {
var valid = &quot;0123456789&quot;
var length = 13
var ok = &quot;yes&quot;;
var temp;
for (var i=0; i<field.value.length; i++) {
temp = &quot;&quot; + field.value.substring(i, i+1);
if (valid.indexOf(temp) == &quot;-1&quot ok = &quot;no&quot;;
}
if (ok == &quot;no&quot {
alert(&quot;Invalid entry! NSNs can only contain integers and must be 13 digits.&quot;
field.focus();
field.select();
}
}
// End -->
</script>

Thanks.

Will the following not work??

<SCRIPT LANGUAGE=&quot;JavaScript&quot;>

<!-- Begin
function validate(field) {
var valid = &quot;0123456789&quot;
var length = 13
var ok = &quot;yes&quot;;
var temp;
for (var i=0; i<field.value.length; i++) {
temp = &quot;&quot; + field.value.substring(i, i+1);
if (valid.indexOf(temp) == &quot;-1&quot ok = &quot;no&quot;;
}
if (field.value.length != 13) {ok = &quot;no&quot;;}

if (ok == &quot;no&quot {
alert(&quot;Invalid entry! NSNs can only contain integers and must be 13 digits.&quot;
field.focus();
field.select();
}
}
// End -->
</script>

It works well. Someone else sent me this

if(parseFloat(fieldLength)<13)
{
ok = &quot;no&quot;;
}

which also works.

Thanks for the response.
