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.

Then please demonstrate your attempts at solving the problem using your research; explain where your attempts fail. How they fail. What you expected to happen and what happened instead.

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”,””);
