Limit value for text field

In Acrobat 8 Professional, look at the "Validation" tab for the field.

Thank you for your assistance.

Would you please provide short validation script? I would like to provide dialog box if the number entered is outside the range.

Thank you.

Limit length of field to 2. Add a Validation Script Message on the Value tab. Type in the following code into the validate event of the field:

this.isNull || (!isNaN(this.rawValue) && this.rawValue > 0 && this.rawValue < 23)Ciao

In the solution above you can type in values like "1." or ".3". A more secure solution is:

Limit length of field to 2. Add a Script Object called FormScript. Copy the function:

function isValid(text, field_name)
{
var returnWert;
var thisRegExp = new RegExp();

returnWert = true;

//set regular expression
thisRegExp.compile("^[0-9]{0,2}$","i");

if ((text != null) && ((thisRegExp.test(text) == false) || (text < 1 || text > 22)))
{
xfa.host.messageBox("Field invalid!", "Exception", 0);
xfa.resolveNode(field_name).rawValue = null;
xfa.host.setFocus(field_name);
returnWert = false;
}

return returnWert;
}

Now call the function from the validate event of the field
FormScript.isValid(this.rawValue, this.somExpression);

Ciao
