You can do it like this:

$('textarea').keyup(function(){
   var mystr = $(this).val();
   var myarr = mystr.split("-");
   var myvar = myarr[0].toUpperCase() + "-" + myarr[1];
});

Using the split to separate the values and the toUpperCase to be converted into an uppercase.

Remembering that this solution was made for a single -

  • It wouldn’t be right to access the array by the beginning 0? myarr[0].toUpperCase(). What happens if he has multiple strokes -?

  • really @gabrielhof didn’t think about the chance to have you more than one - and the indices are correct

  • Take a look at what happens: http://jsfiddle.net/qbbgx3e7/

    yes @gabrielhof already edited the answer adjusting the array and tested together in your fiddle worked

function beforeDash( val ){
    return val.replace(/(?:\w+-)/g, function(match){
        return match.toUpperCase()
    });
}
