javascript - Regex for international numbers - no space -


I am trying to create a regEx which will have the optional '+' as the first character and then accept all the digits After doing this, make sure no spaces are allowed

I have tried the following, but it does not seem to work: 

  New RegExp (/ ^ \ +? \ $$$);

Looks like you want something like that, 

 < Code> New RegExp (/ ^ \?? \ D + $ /);   
 Change the location with  +  in your regex  \ d +  matches one or more digits.
