• javascript
• jquery
• regex

• If you have no control over the var type of the pattern you receive, but you are sure it is always passed like that, you may use var ining="/^0[94]\\d{8}$/g"; and then var regex = new RegExp(ining.replace(/^\/(.*)\/g$/, "$1"));. See this plunkr. – Wiktor Stribiżew Commented Aug 16, 2017 at 7:33

This regex is working for me:

/^0(9|4)\d{8}$/

Explained:

^ - means start of line
0 - leading zero is mandatory
(9|4) - this is saying that the zero has to be followed by either a 9 or a 4
\d{8} - next, there have to be 8 digits
$ - means end of line

This regex is fairly simple and it works:

/(09|04)\d{8}/g

Explained:

• (09|04) says match the group (09|04) (a group is essentially a sequence to match), where the sequence to be matched is 09 OR (the | symbol) 04.
• Next, \d{8} says match exactly 8 digits following the (09|04) group.
• Finally, g sets the global flag (allowing for more than one match).

I hope this helped!

I hope this helps you.

var regex = /^0(9|4)\d{8}$/
alert(regex.test('0412345678')); //true
alert(regex.test('0912345678')); //true
alert(regex.test('0512345678')); //false

var regex = new RegExp(/^0(9|4)\d{8}$/);
alert(regex.test('0412345678')); //true
alert(regex.test('0912345678')); //true
alert(regex.test('0512345678')); //false

In asp code Entity you can use following code:

RegularExpression(@"^0(9|4)[0-9\d]{8}$", ErrorMessage = "Your message")]
