I am working in a project which it needs to get a phone number from a string. the string is like this in Java Script array named dine

{

"group": 1, 



"tel1": "Tél(1): 05.82.77.31.78", 

"tel2": "Tél(2): 09.55.86.31.45", 



}, 

,...

I want to use pure phone numbers in a tag like this

<a href="tel:0970500469">Tél: 09.70.50.04.69</a>

I have used this java script codes

for (var i = 0; i < dine.length; i++) {

  telnom = dine[i].tel1;

  telnom = telnom.replace(/D/g, '');



  alert(telnom);



  telnom2 = dine[i].tel2;

  telnom2 = telnom2.replace(/D/g, '');

  alert(telnom2);



  infoHtml += '<div class="info">n <p> <a href="tel:' + telnom + '">' + dine[i].tel1 + '</a></p>n    <p> <a href="tel:' + telnom2 + '">' + dine[i].tel2 + '</a></p>n  n</div>';

}

the problem is that it added 1 at the beginning of my phone number that it seems belongs to the Tél(1) and makes the telnom1 like this : 10970500469 while I want to call 0970500469

I am sure the problem stand for the way I used replace codes but I really do not know how to correct it.

 telnom = dine[i].tel1;



 telnom = telnom.replace(/D/g, '');



 telnom2 = dine[i].tel2;



 telnom2 = telnom2.replace(/D/g, '');

I really appreciate any help. thank you

You need to remove any digits that appear within brackets, as well as non digits. Your regext should be /((d*)|D)/g

var telnom = "Tel:(1) - 05.34.36.15"



telnom = telnom.replace(/((d*)|D)/g, '');



console.log(telnom);   //05343615

If your phone numbers always start with something like Tel:, Tel(1): etc you could, for example, consider simply splitting the whole string first using : (or a space) as separators. Like this:

telnom = dine[i].tel1;

telnom = telnom.split(":")[1].replace(/D/g, '');

You can use the following regex to get the desired telephone number:

var n = "Tél(1): 05.82.77.31.78".match(/[d]d+/g).join("");

console.log(n);

Explanation: [d] matches only numbers and we are adding another d so only two numbers which are side-by-side matches. Next, we join them to a single string. If you need number instead of the string you can do following:
Number(n)
