Looking to implement phone number validation in ionic 2, I came across an example on intlpnIonic which was designed for ionic 1. However, I want to achieve something similar to the image provided here: https://i.sstatic.net/qqSak.png
My Query : How can I create a phone number validation like the one shown in the image?.

Additionally, you can review the following code snippet
static isValidMobile(control: FormControl): any {
let regExp = /^[0-9]{10}$/;
if (!regExp.test(control.value)) {
return {"invalidMobile": true};
}
return null;
}
This method has been incredibly successful for me...
I have integrated a third-party library called intl-tel-input into my project.
1- Start by installing jQuery:
npm install --save jquery
Next, import jquery into any of your app files like so:
import $ from "jquery";
You can now use it as follows:
$('#elemId').width();
2- Install the intl-tel-input library:
npm install intl-tel-input --save
Similarly, import intl-tel-input into your app files:
import 'intl-tel-input';
And use it in your code as shown below:
ngOnInit(): any {
let telInput = $("#elemtId");
let output = $("#output");
telInput.intlTelInput();
telInput.on("keyup change", function() {
var intlNumber = telInput.intlTelInput("getNumber");
if (intlNumber) {
output.text("International: " + intlNumber);
} else {
output.text("Please enter a number below");
}
});
}
home.html
<p id="output">Please enter a number below</p>
<input id="elemtId" type="tel">
