assuming a function like this:

  var email = "myemail@gmail.com";
  var username = email.substring(0, email.indexOf('\\@'))

According to the jquery documentation, '\\' should escape the @ character, but it doesn't work. How can I specify the '@' character?

edit: please see screenshot of my function. As you can see the @ character is being interpreted in a special way , because of Razor maybe?

You don't need to escape the "@" in the indexOf function. This is standard javascript :

var email = "myemail@gmail.com";
  var username = email.substring(0, email.indexOf('@'));
  console.log(username );

Edit : for Razor engine ... Use indexOf('@@') to escape the @ symbol
