Check working example,

$(document).ready(function () {
   MobEncrypt();
   EmailEncrypt()
});

function MobEncrypt() {
var value = '9999888877';
    // make a string with x-characters
    var x = new Array(value.length - 3).join('X');
    // join this string with the tail of the value, and replace it
    alert(x + value.substr(value.length - 3));
}

function EmailEncrypt() {
var value = 'raju327@gmail.com';
    // make a string with x-characters
    var x = new Array(value.length - 5).join('X');
    // join this string with the tail of the value, and replace it
    alert(x + value.substr(value.length - 5));
}
