By using capturing groups to remember each set of digits, the same regular expression can be used to replace the subject text with precisely the format you want. Two other types of tokens used in this regular expression are character classes and quantifiers.
See Recipes 3.5 and 3.15 for help implementing this regular expression with other programming languages. Character classes allow you to match any one out of a set of characters.
This jquery validation code allows you to enter and check the international telephone numbers.
Some advanced features of intl-tel-input is listed below1)All countries telephone code are shown with their flag as a drop list.2)The code displays up-to-date pattern of phone numbers in the world.3)The data obtain from Google libphone number library so it is completely reliable.4)It lists all the countries and their international dial codes next to their flags.
The regexes in these recipes are all pretty straightforward, but hopefully this gives an example of the depth you can expect from the book. Both are followed by a question mark, which makes them optional.
For more than 100 detailed regular expression recipes that include equal coverage for eight programming languages (C#, Java, Java Script, Perl, PHP, Python, Ruby, and VB. We’ll explain more about the question mark after discussing the other types of tokens in this regular expression.
Some quick searching turned up Robert Freeman’s blog where he gives a great formula for ensuring phone numbers are entered in the form (###) ###-####. However, I wanted to make sure I understood it so I broke it out into logical sections and went through it.
I’ve taken his formula and added 2 additional checks =AND( LEN([Phone])=14, IF(ISERROR(FIND("(", [Phone],1)), FALSE, (FIND("(", [Phone]) = 1) ), IF(ISERROR(FIND(")", [Phone],5)), FALSE, (FIND(")", [Phone], 5) = 5) ), IF(ISERROR(FIND(" ", [Phone],6)), FALSE, (FIND(" ", [Phone], 6) = 6) ), IF(ISERROR(FIND("-", [Phone],10)), FALSE, (FIND("-", [Phone], 10) = 10) ), IF(ISERROR(1*CONCATENATE(MID([Phone], 2, 3), MID([Phone], 7, 3), MID([Phone], 11, 4))), FALSE, AND( 1*CONCATENATE(MID([Phone], 2, 3), MID([Phone], 7, 3), MID([Phone], 11, 4)) To get this working in Share Point, just copy the above and do a find and replace on [Phone] with whatever your column is named.
Note: to help preserve the paper tags, hunters need only attach the tag before leaving the carcass. The jquery code given below is used to validate telephone numbers. There are no errors which are specific to this method.Each year across EMEA, we host Automation Universities specifically aimed at engineers, business managers, consultants and system integrators.Automation University Classic is the original format of this popular event which is open to everyone interested in leading-edge automation solutions.
