    Hi! Please take the tour (you get a badge!) and read through the help center, in particular How do I ask a good question? Your best bet here is to do your research, search for related topics on SO, and give it a go. If you get stuck and can't get unstuck after doing more research and searching, post a Minimal, Complete, and Verifiable example of your attempt and say specifically where you're stuck. People will be glad to help.

The simplest and the most robust method would be to remove all non-numerical values from the string which can be done using a simple regex:






var tel = "Tel: 01.78.99.93.06";

var nom = tel.replace(/D/g, '');

console.log(nom);

Use replace. If your var is called telephone, then do: 



telephone = telephone.replace(“.”,””).replace(“other unwanted strings”,””);
