Hindi mo pa yata na explore ang js regex. Hindi totoo yan. Hindi mo lang alam gamitin ng tama yung mga special characters.

Pasensya na siya. Javascript po talaga ako nahihirapan intindihin. sige po aralin ko. pasensyan ulit

 

[the_flash]

or you can use php
tas bilangin mo ang input if 7 or 11 else, if other than 7 at 11, invalid na kasi dapat either telephone number at phone number lang sa pilipinas diba?

if you want, check mo rin if 11 siya, check mo if ang simula ay 09 else, mali/hindi phone number

teka try ko wahahhahah

Ito na okay na siya. Lagay mo lang sa isang .php file yang code na yan then run mo na

<?php
if ($_SERVER['REQUEST_METHOD'] == "POST") {
    $txtNumber = $_POST['txtNumber'];
    if ($txtNumber == null) {
        echo "<script>alert('Can\'t be empty!');</script>";
    }else{
        if ((strlen($txtNumber) == "11") && (substr($txtNumber, 0,2) == "09")) {
            echo "<script>alert('Cellphone number');</script>";
        }else if (strlen($txtNumber) == "7") {
            echo "<script>alert('Telephone number');</script>";
        }else{
            echo "<script>alert('Invalid number!');</script>";
        }
    }
}
?>
<form action="#" method="post">
<center>
<input type="number" name="txtNumber" placeholder="Phone/Telephone" style="padding: 20px;">
<input type="submit" style="padding: 20px">
</center></form>
