How to add validation of mobile no dyanamically in js

Question

How to add validation of mobile no. Html code:<input type="text" id="mob" name="mob[]" placeholder="Enter mobile no" required>

js code

container.appendChild(document.createTextNode("mobile")); var input_m = document.createElement("input"); input_m.type = "text"; input_m.id= id+'_mobile'; input_m.name= "mob[]"; container.appendChild(input_m);

For Indian numbers: /[7-9][0-9]{9}/. Note this is a basic validation regex. This will not cover cases like 9999999999 — Rajesh Dixit

Well you can do this through regex:

function phonenumber(inputtxt) { var phoneno = /^\d{10}$/; if((inputtxt.value.match(phoneno)) { return true; } else { alert("message"); return false; } }
