$('input').on('keypress', function (event) {
    var regex = new RegExp("^[a-zA-Z0-9]+$");
    var key = String.fromCharCode(!event.charCode ? event.which : event.charCode);
    if (!regex.test(key)) {
       event.preventDefault();
       return false;
    }
});

Oh in that case probably you can try this on submit 

string str = “$@/\/\”;
var regex = /^[^a-zA-Z0-9]+$/;

 var onlySpl = regex.test(str);

        if (onlySpl) 

// show notification
