I am trying to format a text field phone number to show dashes and have found two ways. One using JS and the other using Matches Regex. I tried both examples and was not successful in my attempts. Can someone provide me direction on the best way to format a phone number so it will show the dashes in the field.

e.preventDefault();
});
jQuery(".InputText").on('keypress',function(){
if(event.which != 8 && isNaN(String.fromCharCode(event.which))){
event.preventDefault(); //stop character from entering input
}
var s = this.value.replace(/-/g,'');
if(s.length==10){
event.preventDefault();
}
if(s.length!=0){
if(s.length>=3 && s.length<=5){
var s1 = s.slice(0,3);
var s2 =s.slice(3,s.length);
this.value=s1+"-"+s2;
}
if(s.length>=6){
var s1 = s.slice(0,3);
var s2 =s.slice(3,6);
var s3=s.slice(6,s.length);
this.value=s1+"-"+s2+"-"+s3;

Look at the jquery input mask: jquery-input-mask-phone-number - npm (npmjs.com)
