Random 'email format' text using jQuery

Question

I want to know how I can get a random text variable in jQuery like this format:

[email protected]

15 digit random combination of letters and numbers in the first part and '@domain.com' in the second part which remains the same.

I want to get real random entries that are different all the time.

how to do this with javascript or jquery?

Thanks

Answer 1

Use chancejs github

email

chance.email()
chance.email({domain: "example.com"}) 

Return a random email with a random domain.

chance.email()
=> '[email protected]'

Optionally specify a domain and the email will be random but the domain will not.

chance.email({domain: 'example.com')
=> '[email protected]'

Or pure JavaScript

fiddle DEMO

function makeEmail() {
    var strValues = "abcdefg12345";
    var strEmail = "";
    var strTmp;
    for (var i = 0; i < 10; i++) {
        strTmp = strValues.charAt(Math.round(strValues.length * Math.random()));
        strEmail = strEmail + strTmp;
    }
    strTmp = "";
    strEmail = strEmail + "@";
    for (var j = 0; j < 8; j++) {
        strTmp = strValues.charAt(Math.round(strValues.length * Math.random()));
        strEmail = strEmail + strTmp;
    }
    strEmail = strEmail + ".com"
    return strEmail;
}
console.log(makeEmail());

Answer 2

var chars = 'abcdefghijklmnopqrstuvwxyz1234567890';
var string = '';
for(var ii=0; ii<15; ii++){
    string += chars[Math.floor(Math.random() * chars.length)];
}
alert(string + '@domain.com');

This will randomly pick characters to add to the email string.

Note that this might, once in a blue moon, generate duplicates. In order to completely eliminate duplicates, you would have to store all generated strings and check to make sure that the one you are generating is unique.
