用于最小和最大长度检查的正则表达式用于电话号码验证

Question

I need a simple javascript regex to validate phone numbers. Only digits, "+" at the beginning and "-"
Max and min length of digits should be 10 - 12

The next phones should be allowed:
1. +380631505624
2. 0631505624
3. 063-15-05-624

The next phones should be NOT allowed:
1. +38063+1505624
2. asd0631505624
3. -063-15-05-624-
4. +0---3-1--24

Answer 1

The Comment of Quentin is the way to go , but a Regex - Expression for your needs could be:

^\+?\d+(\d\-|\d)+\d$

I hope it helps, or is atleast a point in the right direction

It all depends on how save/strict you want to check

BTW.: is javascript ist would look something like this

 ...
 if (/^\+?(\d\-|\d)+\d$/ig.test("+43595-995-995")){
    alert("GOOD");
 }
 ...

Here you can find a working demo( On JsFiddler ) tested wit Chrome 24+ (with all numbers of your question)

Answer 2

In above code there has no any lenght validation, so I am just correcting the above answer

http://jsfiddle.net/KRwHQ/4/

 if (/^\+?((\d\-|\d)+\d){4,}$/ig.test("+43595-995-995")){
     alert("GOOD");
 }
