How do you ensure that what I typed in the Phone number must be an 8 digit number?

Question

Hi all,
I am now creating a text box that allows a person to type in an 8 digit phone number according to my country's specifications. If a person types in a single digit, how do I have a validation check to ensure that he has to type in 8 digits? Under Validation Pattern, I typed in 99999999 but the person can still type in a single digit and still pass through! It will only validate when a person types in more than 8 digits.
What gives?
Thanks for reading!

Answer 1

Again, I use code to check the string against a regular expression. My expressiong validates that a string contains valid US phone pattern. Ex. [phone] or [phone] or 1234567890
Here's my function that I put in a script object called scoAllScripts:
function validateUSPhone(strValue) {
DESCRIPTION: Validates that a string contains valid
US phone pattern.
Ex. [phone] or [phone] or 1234567890
PARAMETERS:
strValue - String to be tested for validity
RETURNS:
True if valid, otherwise false.
var objRegExp = /(^\d{10}$)|(^\([1-9]\d{2}\)\s?\d{3}\-\d{4}$)/;
//check for valid us phone with or without space between
//area code
return objRegExp.test(strValue);
Here is the code that I put in the Exit event of my phone number field:
if (!this.rawValue == "") {
if(!xfa.form.FSOrder.PAGE1.variables.scoAllScripts.validateUSPhone(this.formattedValue)) {
xfa.host.messageBox("Please enter a telephone number including area code in the format '1234567890' or '[phone]'");
Hope that helps.
If you need more help with field validation (i.e, more regular expressions), you can easily find RegExpr pages using a Google search.
