Setting Max Length on a Catalog Item Variable

[NonaJohnson]

Hi,

I am trying to create a maxLength script on a catalog item variable that will work like the attribute used on dictionary field where they set the attribute on the field to max_length=50.  Here the text just stops after that number of characters.  I'd like to crate that same functionality on a catalog item variable in an OnChange client script (or do I need to use onLoad). The variable only shows after another selection is made so thought the onChange script would be needed.

I've tried:

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}

var maxLength = 30;
var descr = g_form.getControl('application_description');
if(descr.value.length > maxLength){
g_form.setValue('application_description','');
alert('Please enter only 30 characters or less');

}

}

And just a standard onChange to just give me the alert

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}

//Type appropriate comment here, and begin script below
if(newValue.length > 30){
g_form.setValue('application_description','');
alert('Please enter only 30 characters or less');
}
}

What they really want is for the user to not be able to input more than 30 char - i.e. text no longer shows like we can do on a dictionary field.

How can I achieve this

Thanks

And if it's about just a validation, have you considered Variable Validation Regex instead? Almost no coding needed to achieve the same.

Thank you Mark - completely forgot about default value/attributes.
